このガイドを信頼する理由

I have used Harvey directly for over a year across real client matters in legal and professional services. This Harvey guide comes from hands-on practice, not vendor screenshots or marketing notes.

Along the way I tested every feature on live work, made plenty of mistakes, and learned what actually saves time. Those lessons shape every step in this guide.

Harvey is one of the most capable AIツール built for legal teams and professional services firms today.

But most legal professionals only scratch the surface of what the platform can do.

This guide shows you how to use every major feature at your own pace.

Step by step, with screenshots, videos, and pro tips for law firms of any size.

Harvey Tutorial

This complete Harvey tutorial walks you through every feature step by step, from your first setup to advanced practices that turn you into a power user across legal documents and legal research.

You do not need to read it in order. Jump to the feature you need, or work through each section at your own pace.

Every step uses plain language, so a new associate and a senior partner can both follow along with ease.

Getting Started with Harvey

まずはこちらの簡単な概要をご覧ください。

Now let’s walk through each step so you learn the basics fast.

Step 1: Request Access and Sign In

Go to Harvey’s website and request access for your firm or team.

Harvey is sold to legal teams, so you sign in through a verified workspace rather than a public free trial.

A member of the Harvey team usually confirms your firm before granting access, which keeps the platform secure.

✓ チェックポイント: チェックしてください 受信トレイ for a confirmation email and your workspace invite.

Step 2: Open Your Workspace

Log in with your new account and open the main workspace.

This is the home page where you upload documents, run research, and start any workflow.

Take a minute to explore the layout, since knowing where each tool lives saves time on your first real matter.

✓ チェックポイント: あなたは見るべきです アシスタント search bar and your document library.

Step 3: Connect Your Sources and Tools

Connect Microsoft Word, Outlook, and your document management system so Harvey can pull context from real files.

Harvey connects with iManage and Vault, which keeps your knowledge and history in one place.

Connecting these sources 早い means your first queries draw on real documents instead of a blank workspace.

How to Use Harvey AI Assistant

AIアシスタント lets you ask legal questions and get cited answers pulled from your own documents and trusted sources.

The Assistant is the heart of Harvey for most legal teams. It reads the documents you upload, pulls context from connected sources, and returns answers with citations you can check. Because it is trained on legal language, it understands contracts, complaints, and case law better than a general chatbot. That expertise is what makes it safe to use on real client matters.

Picture a junior associate facing a 90-page agreement at 6 p.m. With the Assistant, they upload the file, ask for the key obligations, and get a cited summary in minutes. That same task once took hours, and the time saved goes straight back into higher-value analysis.

以下に、その使用方法をステップごとに説明します。

AIアシスタントの動作をご覧ください：

それでは、各ステップを詳しく見ていきましょう。

ステップ1：アシスタントを開く

Open the Assistant from your workspace home page and start a new chat.

Type a clear prompt that describes the matter, the client, and the 質問 you need answered.

Step 2: Add Context and Documents

Upload contracts, complaints, or notes so the Assistant can analyze the real 文章.

これがその様子です。

✓ チェックポイント: The Assistant pulls context from connected sources, then drafts answers with citations you can verify.

Step 3: Review and Export the Response

Read the cited responses, check the sources, and refine your prompts as needed.

Export the answer to Microsoft Word or paste it directly into your draft.

For legal teams, this turns a blank page into a cited first draft in minutes, which is why the Assistant is where most users start.

How to Use Harvey Supercharged Legal Research

スーパーチャージされた法的調査 lets you run legal research across case law, statutes, and articles without leaving the platform.

Legal research used to mean hours in a paid library checking one query at a time. Harvey changes that pace. You describe the matter in plain language, pick your trusted sources, and the platform returns grounded analysis with citations. This boosts efficiency for legal professionals who bill by the hour and need answers they can defend.

Trusted sources are what separate a real legal research tool from a generic chatbot. Harvey lets you steer each query toward the case law, statutes, and articles that matter, so the answers you build on are grounded rather than invented.

以下に、その使用方法をステップごとに説明します。

Step 1: Start a Research Query

Open legal research and type a plain-language query about your matter.

Describe the jurisdiction, the governing law, and the practices you want Harvey to check.

Step 2: Choose Trusted Sources

Pick the sources Harvey should search, including case law, statutes, and articles.

これがその様子です。

✓ チェックポイント: Harvey researches legal queries against trusted sources so your answers stay grounded in real law.

Step 3: Save Citations to Your Library

Save the citations and answers into your library for the matter.

Keep the research history so your team can reuse the analysis later.

Used well, legal research in Harvey gives smaller firms the same depth of analysis that once belonged only to large law firms with big libraries.

How to Use Harvey Workflow Automation

ワークフロー オートメーション lets you automate repeat legal processes so your team saves hours on routine matters.

Every firm repeats the same legal processes again and again. Diligence, intake, and clause review all follow a pattern. Harvey lets you build custom workflows that capture that pattern once, then run it on demand. The result is real efficiency gains, since your team stops rebuilding the same analysis for every new matter.

その ビルダー is visual, so you do not need to write code to build custom workflows. You arrange prompts, inputs, and review tables like building blocks, then test the flow on sample files before your team relies on it for live matters.

以下に、その使用方法をステップごとに説明します。

Step 1: Pick a Process to Automate

Choose a repeat legal process, such as a diligence review or a contract check.

Map the steps your team takes today so Harvey can mirror your real practices.

Step 2: Build Custom Workflows

Use the builder to build custom workflows tailored to your firm’s matters.

これがその様子です。

✓ チェックポイント: Add prompts, document inputs, and review tables so the workflow generates consistent output every run.

Step 3: Test Before You Deploy

Run end-to-end testing on sanitized agreements before you deploy to the whole team.

Human oversight stays essential, so verify each output before it reaches a client.

Over time, a library of tested workflows becomes one of your firm’s most valuable assets, capturing expertise so it survives staff changes.

How to Use Harvey Governance Controls

Governance Controls lets you manage security, privacy, and compliance settings across your whole workspace.

Governance is where many AI tools fall short, but Harvey treats it as essential. You control who can access which matters, how data is handled, and what the 監査 history records. For law firms and in-house teams, this is the difference between a fun experiment and a tool you can actually trust with client data.

Audit logs may sound dull, but they are gold during a security review. When leadership or a client asks who accessed what, you have a clear record of every request, which keeps your firm transparent and compliant.

以下に、その使用方法をステップごとに説明します。

Step 1: Open the Admin Settings

Open admin settings to manage access, data, and compliance for your workspace.

Assign roles so legal professionals only see the matters they should.

Step 2: Set Access and Privacy Rules

Turn on SAML SSO, audit logs, and IP allow-listing for tighter security.

これがその様子です。

✓ チェックポイント: Harvey does not use client data for model training, which protects privacy across your firm.

Step 3: Review the Audit History

Check audit logs to see who used Harvey, what they asked, and when.

This history gives in-house and 法律事務所 teams a clear compliance record.

Strong governance is what lets leadership roll Harvey out across the whole firm with confidence instead of limiting it to a small pilot group.

How to Use Harvey Integrations

統合 lets you connect Harvey with Microsoft Word, Outlook, and document systems you already use.

Most legal work already lives in Microsoft Word, Outlook, and a document management system. Harvey meets your team there instead of forcing a new home for everything. You draft in Word, send email in Outlook, and pull files from iManage or Vault, all while Harvey keeps the legal context intact across each tool.

Switching tools all day breaks concentration and loses context. By living inside Word, Outlook, and your document system, Harvey keeps you in flow, so drafting an email or a contract feels like a natural part of the work, not a detour.

以下に、その使用方法をステップごとに説明します。

ステップ1：統合メニューを開きます

Open the integrations menu to connect the tools your team already uses.

Harvey connects with Microsoft Word, Outlook, iManage, and Vault.

Step 2: Draft Inside Word and Outlook

Draft documents in Microsoft Word and draft emails in Outlook using Harvey directly.

これがその様子です。

✓ チェックポイント: You get instant summaries and email drafting without switching tabs or losing context.

Step 3: Export Results for Analysis

Export review results to Excel so your team can run deeper analysis.

This keeps your data flowing between Harvey and the apps you trust.

Because the integrations keep context intact, your team gains efficiency without giving up the tools and practices they already know.

How to Use Harvey Pre-Built Workflows

Pre-Built Workflows lets you apply ready-made playbooks that analyze clauses against legal standards in one click.

Pre-built workflows give newer users a head start. Instead of writing prompts from scratch, you pick a playbook that already knows how to analyze clauses against legal standards. This lowers the learning curve so even users new to legal AI can produce useful analysis on day one while they learn the platform.

Each playbook encodes the judgment of experienced lawyers into a repeatable process. When you run one, you borrow that expertise, which is why even a small team can produce review-grade analysis that once required a much larger group.

以下に、その使用方法をステップごとに説明します。

Step 1: Browse the Workflow Library

Open the library of pre-built workflows made for common legal matters.

Each playbook automates clause analysis against legal standards so you start fast.

Step 2: Run a Playbook on Your Files

Upload your contracts and run the chosen playbook against them.

これがその様子です。

✓ チェックポイント: Harvey flags risky clauses, missing terms, and governing law issues for review.

Step 3: Refine and Save Your Version

Edit the playbook prompts to match your firm’s practices.

Save your version so the whole team can reuse it on future matters.

Pre-built workflows are also a great way for new users to learn how Harvey thinks before they build custom workflows of their own.

How to Use Harvey Vault

Vault lets you store vast amounts of legal documents in a single searchable workspace.

Vault is where Harvey stores institutional knowledge. Drop in every document for a matter and the whole set becomes searchable in seconds. For litigation and diligence, where you face vast amounts of files, Vault turns a slow manual hunt into a fast, cited search across your entire library.

Search inside Vault is fast because every page is indexed as you upload. Ask a question about a clause buried on page 200 of a contract set, and Harvey points you to the exact spot, with the surrounding context attached.

以下に、その使用方法をステップごとに説明します。

Step 1: Create a New Vault

Create a Vault to centralize documents and research into one searchable workspace.

Vault can store vast amounts of files for a single matter or client.

Step 2: Upload and Organize Files

Upload contracts, complaints, and notes, then organize them by matter.

これがその様子です。

✓ チェックポイント: Search across the whole Vault to find any page or clause in seconds.

Step 3: Run Review Tables Across Documents

Use Review Tables to extract answers from many documents at once.

Export the review tables to Excel so you can sort and analyze the results.

With everything in one workspace, your team spends less time searching and more time on the analysis that actually moves a matter forward.

How to Use Harvey Legal Research Module

Legal Research Module lets you search trusted legal sources like EDGAR and LexisNexis directly inside Harvey.

The legal research module connects Harvey to the sources legal professionals already trust. You can pull filings from EDGAR, cross-check answers against LexisNexis, and keep a clean research history for each matter. This grounding is what keeps Harvey’s answers tied to real law rather than guesswork.

Keeping a clean research history pays off across a long matter. Months later, you can revisit exactly which sources supported a position, which protects your analysis if a colleague or a court questions how you got there.

以下に、その使用方法をステップごとに説明します。

Step 1: Open the Research Module

Open the legal research module to query trusted legal sources directly.

Harvey connects to sources like EDGAR and LexisNexis for grounded answers.

Step 2: Ask a Legal Question

Type your legal question and describe the matter you are working on.

これがその様子です。

✓ チェックポイント: The module returns cited answers drawn from real case law and filings.

Step 3: Save Sources to Your History

Save the sources and citations into your research history.

Your team can revisit the analysis and reuse it across related matters.

Grounding answers in trusted sources is what gives legal professionals the confidence to rely on Harvey for client-facing work.

How to Use Harvey Enterprise-Grade Protection

Enterprise-Grade Protection lets you protect client data with enterprise-grade controls built for law firms.

Security is not a feature you bolt on later in legal work. Harvey is built so encryption, access controls, and audit logs come standard. The platform does not use client data for model training, which protects privacy and lets your firm meet strict compliance requirements without slowing your team down.

Security settings are worth a careful walk-through with your IT team before launch. Confirm encryption, SSO, and access rules match your firm’s policy, and you turn Harvey from a promising tool into one you can deploy with full confidence.

以下に、その使用方法をステップごとに説明します。

ステップ1：セキュリティ設定を確認する

Open security settings to confirm encryption and access controls are on.

Harvey meets enterprise-grade security and compliance standards for legal teams.

Step 2: Manage Data Lifecycle

Set data lifecycle rules so files are retained or deleted on schedule.

これがその様子です。

✓ チェックポイント: Access is managed per user, and data in Harvey stays encrypted at rest and in transit.

Step 3: Confirm Compliance Coverage

Check that SSO, audit logs, and IP allow-listing match your firm’s policy.

This protects client data and keeps your firm audit-ready.

This is why firms with strict privacy duties can adopt Harvey, knowing client data and matters stay protected at every step.

Who Should Use Harvey?

Harvey is built for legal and professional services teams that handle real client matters at scale.

If your work touches contracts, litigation, or legal research every week, the platform earns its place fast.

Large law firms use Harvey to draft, review, and analyze documents across hundreds of matters at once.

In-house legal teams use it to answer 仕事 questions quickly without sending every query to outside counsel.

Boutique firms use it to punch above their size, since one lawyer with Harvey can review vast amounts of documents in a day.

Professional services firms beyond law also use Harvey for compliance work, due diligence, and contract analysis.

The common thread is that every user needs cited answers, strong security, and real legal expertise baked into the tool.

If you only need a casual writing assistant, a general AIツール may be enough.

But if accuracy, privacy, and legal context matter, Harvey is built for exactly that kind of serious work.

It also suits teams that handle vast amounts of documents and cannot afford to miss a key clause or citation.

And it fits firms that care about security, since client data stays encrypted and is never used for training.

How Harvey Fits Into Your Legal Workflows

The best way to learn Harvey is to map it onto the legal workflows your team already runs.

Start with intake, where you upload a new client’s documents into Vault for a fresh matter.

Next comes research, where the Assistant and the legal research module answer your queries with citations.

Then comes drafting, where Harvey works inside Microsoft Word to create contracts, memos, and letters.

Review is where review tables shine, pulling answers from many documents so you can analyze them side by side.

Email follows, where you draft client updates in Outlook using Harvey directly without leaving your inbox.

Finally, governance runs underneath all of it, recording history and protecting client data at every step.

Seen this way, Harvey is not one feature but a thread that runs through your whole practice.

Each step builds on the last, so your knowledge and analysis stay connected from intake to final filing.

That continuity is what drives the real efficiency gains legal teams notice after a few weeks of steady use.

Best Practices for Using Harvey Safely

Harvey is powerful, but safe legal work still depends on good habits from every user.

First, always give the platform context, since documentation and context are crucial for effective AI usage in law.

Upload the real contracts, complaints, and notes so the Assistant can analyze the actual text, not a guess.

Second, keep human oversight in the loop, because verifying AI-generated outputs is critical before anything reaches a client.

Read every citation, confirm the governing law, and check the analysis against your own legal expertise.

Third, protect client data by using sanitized agreements when you test or train new workflows.

Run end-to-end testing before you deploy any workflow to the wider team, so surprises surface early.

Fourth, build a shared prompt library so your team can learn from each other and keep answers consistent.

Fifth, use the support hub, watch the videos, and read the articles to learn Harvey at your own pace.

These practices keep efficiency high while keeping compliance, privacy, and security firmly in place.

Sixth, treat Harvey as a partner, not a replacement, since your legal expertise is what verifies its work.

The platform speeds up research and drafting, but you still own the final judgment on every client matter.

Followed together, these habits let your team move faster without トレーディング away the care good legal work demands.

Harvey for In-House Teams vs Law Firms

Harvey serves both in-house legal teams and outside law firms, but each group uses it a little differently.

In-house teams focus on speed and business context, since they answer the company’s own questions daily.

They use the Assistant to triage requests, draft routine contracts, and decide which matters need outside counsel.

For them, the value is efficiency, since a small in-house team can handle far more work with the platform’s help.

Law firms focus on depth, billing, and client-ready output across many different clients at once.

They lean on legal research, review tables, and custom workflows to handle complex litigation and diligence.

For firms, the value is expertise at scale, since associates produce better first drafts in less time.

Both groups share the same need for security, citations, and a clear audit history of every request.

Whatever your house, the core practices stay the same: give context, verify outputs, and protect client data.

Many firms run a hybrid model too, where in-house teams handle routine work in Harvey and send complex matters to outside firms that also use it. Shared tooling makes that handoff smoother, since both sides speak the same language and trust the same cited sources.

Harvey Use Cases by Practice Area

Harvey adapts to almost any practice area, since legal research and drafting cut across every field of law.

In litigation, teams upload complaints and exhibits to Vault, then use review tables to find key facts fast.

The Assistant can summarize a deposition, surface contradictions, and draft a motion outline with cited sources.

In transactional work, lawyers run diligence on stacks of contracts and flag risky clauses against legal standards.

Harvey checks governing law, indemnities, and termination terms, then drafts a clean issues list for the client.

In corporate and securities work, the legal research module pulls filings from EDGAR for quick context.

Teams cross-check those filings against LexisNexis so their analysis stays grounded in current law.

In compliance and privacy, in-house teams use Harvey to answer policy queries and draft internal guidance.

In employment law, lawyers analyze handbooks and contracts, then generate plain-language answers for managers.

で 不動産, teams review leases at speed and export the results to Excel for deeper analysis.

Whatever the practice area, the pattern repeats: upload documents, ask clear queries, verify answers, then draft.

This flexibility is why so many users across different teams find Harvey useful within their first week.

How to Get Better Answers From Harvey

The quality of Harvey’s answers depends heavily on how you write your prompts and set up your context.

Start by telling the Assistant who the client is, what the matter involves, and what answer you actually need.

Vague prompts get vague answers, so describe the jurisdiction, the governing law, and the documents in play.

Attach the real files first, since the platform draws its best analysis from the text you upload, not guesswork.

Ask for citations every time, then open each source to confirm the answer matches the underlying law.

If the first response misses, refine your prompt rather than starting over, and add the missing context.

Save the prompts that work into your library so the whole team can reuse them and learn from each other.

Break big questions into smaller steps, since a focused query usually beats one giant request.

When you need a document, ask Harvey to draft it in Microsoft Word so you can edit in your normal tool.

These small habits compound, and over time your team gets faster, sharper answers with far less back and forth.

A few prompt patterns come up again and again, so they are worth keeping in your library from the start.

Ask Harvey to summarize a contract and list every obligation, deadline, and governing law clause it finds.

Ask it to compare two agreements and flag where the terms differ, then draft a short note for the client.

Ask it to research a narrow legal question, cite the sources, and explain how each one applies to your matter.

Save the versions that work, and your team builds a shared playbook of prompts that keep getting better.

What Makes Harvey Different

Plenty of AI tools claim to help lawyers, so it is fair to ask what sets Harvey apart.

The first difference is focus, since Harvey was built only for legal and professional services work.

That narrow focus means the platform speaks the language of contracts, complaints, and case law fluently.

The second difference is grounding, since every answer can carry citations to trusted legal sources.

You are not asked to trust a black box, because you can open each source and check the law yourself.

The third difference is security, since the platform meets enterprise-grade standards from the start.

Harvey does not use client data for model training, which protects privacy across every matter you handle.

The fourth difference is depth, since custom workflows and review tables handle real volume, not just demos.

A team can run a playbook across hundreds of contracts and export the analysis to Excel in one pass.

The fifth difference is reach, since the platform connects to the Microsoft Word and Outlook tools you already use.

Taken together, these traits explain why so many legal teams trust Harvey for client-facing work.

It is less a clever toy and more a working tool that fits the practices serious legal professionals already follow.

How to Roll Out Harvey Across Your Team

Getting one lawyer comfortable with Harvey is easy, but a firm-wide rollout needs a little planning.

Start with a small pilot group of curious users who already feel comfortable with new tools.

Give them a few real but sanitized matters so they can test the platform without risking client data.

Ask each user to build one workflow and run it end to end, then share what worked at a short team meeting.

Collect the best prompts into a shared library so new users start with proven examples, not a blank page.

Point everyone to the support hub, the videos, and the articles so they can learn at their own pace.

Set clear rules early: always add context, always verify outputs, and never paste an answer in without review.

Turn on audit logs and access controls from day one so security and compliance are built in, not bolted on.

As confidence grows, widen access to more legal teams and more practice areas across the firm.

Measure the efficiency gains in real terms, like hours saved on research and faster turnaround on contracts.

Share those wins, since nothing drives adoption like a colleague showing how Harvey saved them an afternoon.

Done this way, the platform spreads through your firm steadily, and the expertise behind it compounds over time.

よくある質問
