このガイドを信頼する理由

I’ve paid for Grok since launch and tested every feature covered here.

This tutorial comes from real hands-on use — not marketing copy or vendor screenshots.

Grokは AIアシスタント built by Elon Musk’s startup xAI.

It lives inside X, formerly Twitter, and now on its own web app too.

Most people only ever ask it one or two questions.

The technology moves fast, so this guide sticks to what works right now.

It shows you how to use grok properly, feature by feature.

Grokチュートリアル

This How to use Grok AI tutorial walks through every feature step by step, from your first sign-up to the api key that powers custom builds.

Grokの始め方

Before you touch any feature, finish this one-time setup.

約3分かかります。

Here’s what the first week of daily use actually looked like:

それでは、各ステップを順を追って見ていきましょう。

ステップ1：アカウントを作成する

Open https://grok.com in your browser, or log in through the x app.

Click Sign Up and enter your email address.

You can also sign in with an existing x account in one click.

✓ チェックポイント: チェックしてください 受信トレイ 確認メールについて。

Step 2: Pick Your Access Route

The free tier works on web, アンドロイド, and iOS with a daily message cap.

Premium and Premium+ subscribers get higher limits inside the x platform itself.

✓ チェックポイント: You should see an empty chat box with a model picker above it.

Step 3: Set Your Privacy Controls

Open settings and decide whether your conversation history feeds model training.

xAI states that a small sample of chats may be read by human reviewers.

Switch that off if you handle client data, then delete any history you don’t want kept.

How to Access Grok Real-Time Knowledge

リアルタイムの知識アクセス lets you pull live information from public posts instead of a frozen training set.

以下に、その使用方法をステップごとに説明します。

Step 1: Ask a Time-Sensitive Question

タイプA 質問 about something happening right now.

Ask about a stock move, a product launch, or a breaking story.

Add the date range you care about for tighter results.

Step 2: Open the Source List

Click the small source counter under the response.

You’ll see the exact public posts and web pages it read.

これがその様子です。

✓ チェックポイント: Every claim in the answer links back to a post or page you can open.

Step 3: Push for Depth

Ask a follow-up like “what changed in the last six hours?”

Each follow-up triggers a fresh search rather than a cached answer.

Grokの高度なツール統合の使い方

高度なツール統合 lets you connect outside tools so a single request can search, calculate, and write code.

以下に、その使用方法をステップごとに説明します。

Step 1: Enable the Tools You Need

Open the tools menu below the input box.

Turn on web search, code execution, or file reading.

Step 2: Write One Combined Request

Give it a task that needs two skills at once.

Ask it to find last quarter’s figures and chart them.

これがその様子です。

✓ チェックポイント: The response shows each tool call it made before the final answer.

Step 3: Wire It Into Your Own Build

Grab an api key from the xAI console for programmatic access.

The api follows the same message format most developers already know.

Grokのマルチモーダル機能の使い方

マルチモーダル機能 lets you read images, screenshots, and diagrams alongside your 文章.

以下に、その使用方法をステップごとに説明します。

Step 1: Attach Your File

Click the paperclip icon and pick an image from your device.

Photos, charts, whiteboard shots, and screenshots all work.

Step 2: Ask a Specific Question About It

Vague prompts get vague answers here.

Ask it to convert a flowchart into working code instead.

これがその様子です。

✓ チェックポイント: The reply references details only visible in the picture you uploaded.

Step 3: Iterate on the Output

Point at the part it got wrong and ask for a fix.

Grok-1.5V was xAI’s first multimodal model, and diagram reading is still its strongest party trick.

How to Use Grok Accessibility

シームレスなアクセシビリティ lets you reach the same assistant from the x app, the web, or a phone.

以下に、その使用方法をステップごとに説明します。

Step 1: Install the Mobile App

Download the app on android or iOS and sign in.

Your chat history syncs across every device automatically.

Step 2: Switch Between Regular Mode and Fun Mode

Regular mode gives you clean, direct answers for work.

Fun mode turns up the humor and the rebellious streak xAI is known for.

これがその様子です。

✓ チェックポイント: A conversation you started on desktop appears in the mobile app within seconds.

Step 3: Pin It Where You Work

Add the web app to your home screen for one-tap access.

声 input works on mobile when typing isn’t practical.

How to Use Grok Image Generator and Editor

画像生成と編集 lets you turn a written description into a finished picture, then edit it.

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：詳細なプロンプトを作成する

Describe the subject, the lighting, and the style.

Short prompts produce generic art, so be specific.

Step 2: Generate and Compare

Send the request and wait a few seconds for the batch.

Pick the strongest option from the set it returns.

これがその様子です。

✓ チェックポイント: You have at least one image that matches the scene you described.

Step 3: Edit With Follow-Up Text

Ask it to change the background or shift the color palette.

Each edit builds on the previous image rather than starting over.

Grok Proのヒントとショートカット

After a year of daily use, here are the shortcuts that actually saved me time.

キーボードショートカット

ほとんどの人が見逃す隠れた機能

• Think mode: Ask it to reason step by step before answering. Accuracy on problem solving jumps noticeably on multi-part questions.
• Document summaries: Paste a long report and ask for the key points. It condenses lengthy files into a short list of actionable findings.
• Trend reading: Ask which topics are climbing on X this week. This is the unique feature no other ai チャットボット can copy.
• Voice chat: Tap the microphone in the mobile app for hands-free ai conversations while you drive or walk.

Grokでよくある間違いを避ける方法

Mistake #1: Treating It Like a Search Engine

Mistake #2: Using Fun Mode for Serious Work

Mistake #3: Trusting Live Data Without Checking

Grokのトラブルシューティング

Problem: You Can’t Access Grok At All

原因： Availability is limited in some regions, and a few features still sit behind a paid x account.

修理： Verify your subscription status first, then confirm the service is live where you are.

Problem: Responses Are Slow or Stall Mid-Answer

原因： A weak connection or an outdated app build, usually during peak hours.

修理： Update to the latest version of the x app, restart the device, and retry on a stable network.

Problem: An Error Message Appears on Every Request

原因： A rate limit on the free tier, or an expired api key on developer accounts.

修理： Wait for the window to reset, or generate a fresh key in the console.

📌 注記： If none of these help, contact xAI support through the help menu.

Grokとは何ですか？

グロク is an ai assistant from xAI that answers questions, helps with work tasks, and holds a conversation with a bit of wit.

Think of it as a witty young man who happens to read every public post on X at once.

The name nods to Robert Heinlein, while the assistant’s tone borrows from the Hitchhiker’s Guide to the Galaxy.

こちらの簡単な概要をご覧ください。

主な機能は以下のとおりです。

• リアルタイムの知識アクセス： Live answers drawn from current posts and trends on X
• 高度なツール統合： Web search, code execution, and api access from one chat
• マルチモーダル機能: Reads images and diagrams, then translates them into code
• シームレスなアクセシビリティ： The same assistant on web, android, iOS, and the x app
• 画像生成と編集： Creates detailed visuals from a text prompt

Real world applications run from drafting a コールドメール to reading a messy financial chart.

Users control how much of their data shapes future user interactions, straight from the settings menu.

For example, ask it to trim a long thread to the relevant points and you get a short list back.

The personality is what most people discover first, and it feels more engaging than a corporate assistant.
