このガイドを信頼する理由

I have used Softgen for eight months and shipped four real projects with it. Every screen here comes from my own account, not a vendor demo.

Softgen is an AI powered platform for building full stack web applications without coding experience.

You describe an app idea in plain words.

The AI writes the frontend, wires the backend, and hands you a codebase you own.

A working build lands in roughly 20 minutes.

Most users stop at one prompt and never touch the deeper tools.

That is where the real speed lives.

This guide shows you how to use Softgen properly, feature by feature.

Softgenチュートリアル

This How to Use Softgen tutorial walks through setup, all five features, and the tips that separate a demo from a shipped product.

Softgenを使い始める

Do this one-time setup before you touch any feature.

約3分かかります。

Here is my walkthrough video of the first run:

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：アカウントを作成する

Go to the Softgen website and click Sign Up.

Enter your email, then confirm the link that lands in your 受信トレイ.

Add wallet credit before your first build, because AI operations bill separately.

✓ チェックポイント: You can log in and reach the account screen.

Step 2: Learn the Dashboard

Softgen runs in the browser, so there is nothing to install.

The dashboard lists your projects, your wallet balance, and the new project button.

Open one project to see the chat panel on the left and the live preview on the right.

これは以下のようなものです。

✓ チェックポイント: You should see an empty project list and a visible credit balance.

ステップ3：最初のプロジェクトを開始する

Click new project and answer the short setup questions.

Pick Frontend for a Next.js page or Full Stack when you need a database.

Full stack projects let you configure Firestore for storage and switch on Firebase Authentication.

Answer the setup questions honestly, since the AI builds directly from your answer.

How to Use Softgen Project Management App

プロジェクト管理アプリ lets you build an internal task tracker that matches how your team already works.

以下に、その使用方法をステップごとに説明します。

Most teams finish this build in one sitting.

Step 1: Describe the Workflow

Open a new project and describe your stages in plain English.

Say what a task looks like, not just that you want tasks.

Name the boards, the fields, and who can see each one.

Companies get the most value here, because the app matches an existing process instead of forcing a new one.

Step 2: Generate and Review the Build

Hit generate and wait while the AI assembles the pages.

Cascade builds the database tables, the list view, and the detail page together.

これは以下のようなものです。

✓ チェックポイント: You should see a task board with working create and edit buttons.

Step 3: Add Roles and Storage

Turn on Firebase Authentication so managers and staff get different access.

Then customize the labels so the board speaks your team language.

How to Use Softgen Nexus Flow

Streamline Projects with Nexus Flow lets you plan the build order before the AI writes any 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: Split the Idea into Phases

Break your app into login, data, and 報告 phases.

Write each phase as one sentence you could hand to a contractor.

Short phases keep the AI accurate and reduce rework.

Nexus Flow is designed for builds too large for one prompt.

Step 2: Approve the Roadmap

Softgen returns a development roadmap for you to approve or edit.

Read it closely, because fixing the plan is cheaper than fixing generated code.

これは以下のようなものです。

✓ チェックポイント: Each phase should list its own screens and data fields.

Step 3: Build One Phase at a Time

Run one phase, test it, then move to the next.

Each finished phase leaves room for changes without breaking what already works.

How to Use Softgen Project Version Controller

プロジェクトのバージョン管理 lets you track every change and roll back a bad edit in seconds.

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 Change Log

Each generation is saved as a restore point automatically.

You do not have to remember to save anything.

The log shows what the AI touched and when.

Scan it after any big prompt to understand which files actually changed.

Step 2: Restore or Compare a Version

Pick any earlier version and restore it with one click.

Nothing is lost, so you can test a risky idea and walk it back.

これは以下のようなものです。

✓ チェックポイント: Your preview should reload with the older layout intact.

Step 3: Export to GitHub

Connect a private repository to keep full ownership of the codebase.

You keep 100% of the code, which matters if you ever hire developers later.

How to Use Softgen Agent

Softgen Agent is Cascade, the AI that reads your request and writes the full stack 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: Write Specific Requirements

Tell Softgen exactly what each screen does and who uses it.

Name the buttons, the fields, and the outcome of every action.

Vague prompts produce generic UI components.

Explain your rules too, like who can delete a record.

ステップ2：カスケードに計画と構築を任せる

The agent drafts a plan, then writes the frontend and backend files.

It follows current standards and practices, so the output looks like normal modern code.

これは以下のようなものです。

✓ チェックポイント: The file tree should show pages, components, and API routes.

Step 3: Iterate on the Output

Reply with corrections and let the agent apply your improvements.

Change one thing per message and the results stay predictable.

How to Use Softgen AI App Builder

人工知能 アプリビルダー turns one description into production-ready applications you can publish.

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 Template or Start Blank

Pre-built templates accelerate the first draft for common app types.

Booking tools, directories, and dashboards all have a starting point.

Blank builds suit unusual products with specific requirements.

Every template allows full customization, so nothing locks you in.

Step 2: Generate Content and Images

The AI writes your copy and creates matching images for each page.

That saves the hour most people burn hunting for placeholder text.

これは以下のようなものです。

✓ チェックポイント: Your live preview should load a fully functional app.

Step 3: Test, Then Deploy

You can leverage the AI bug finder to catch broken links and dead buttons.

Fix what it flags, then deploy from the dashboard.

Softgen Pro Tips and Shortcuts

After eight months of building with Softgen, these are the tricks I keep reusing.

キーボードショートカット

アクション	ショートカット
Send prompt to the agent	Ctrl + Enter
New line inside a prompt	Shift + Enter
Refresh the live preview	Ctrl + R
Search inside your code	Ctrl + F

ほとんどの人が見逃す隠れた機能

• Wallet alerts: Set a low balance warning so a long build never stops halfway.
• Image regeneration: Re-roll a single picture instead of rebuilding the whole page.
• 履歴をすぐに表示します: Reopen an old prompt and edit it rather than typing it again.
• Component reuse: Ask the agent to reuse an existing card before it invents a new one.
• Seed data: Request sample records during the build so empty screens still look real.

One more habit worth building: keep a short note of what you asked for in each session.

It makes the next round of improvements far faster.

Softgen Common Mistakes to Avoid

間違いその1：巨大なプロンプトを1つだけ書く

This is the mistake that costs people the most wallet credit.

間違いその2：プレビューをスキップする

Sign up as a fake user and complete the journey end to end.

Mistake #3: Ignoring the code

Softgen Troubleshooting

Problem: The build stalls partway through

原因： Your wallet ran dry mid-generation.

修理： Top up the balance and 再開する from the last saved version.

Long full stack builds burn credits faster than small edits, so budget for the first day.

Problem: The app loads slowly

原因： Poor performance usually traces to external services rather than the generated pages.

修理： Trim outside calls and cache the data your app reads most.

Ask the agent to paginate any list longer than fifty rows.

Problem: Login fails after a change

原因： Firestore rules were rewritten during a later edit.

修理： Restore the previous version, then reapply the change in a smaller step.

Name your auth rules in the prompt so later edits do not overwrite them.

📌 注記： If none of these fix your issue, contact Softgen support.

Softgenとは何ですか?

ソフトジェン is a no-code app builder that writes full stack web applications from a description.

Think of it like hiring a junior developer who works in minutes instead of weeks.

It is built mainly for non-technical founders launching an MVP without manual coding.

Softgen AI stands apart from other AI tools because it handles the backend, not just the interface.

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。

• プロジェクト管理アプリ： Internal trackers built around your own process.
• Streamline Projects with Nexus Flow: A phased roadmap that keeps big builds on track.
• プロジェクトのバージョン管理: Restore points plus GitHub export for full ownership.
• Softgen Agent: Cascade reads your request and writes the code.

ソフトジェン価格

Here is what Softgen costs in 2026:

プラン	価格	最適な用途
Softgenに参加しよう	年間33ドル	Founders and small teams building web apps all year

The licence is only half the bill.

That yearly figure buys the platform access, not unlimited generation.

AI operations run on a separate pay-as-you-go wallet, so heavy building costs more than light editing.

Plan for a larger wallet spend in week one, then a small trickle afterwards.

無料トライアル: No open trial. You can explore the dashboard after you sign up.

返金保証: Not advertised. Ask support before you buy.

💰 最もお得な価格: Join Softgen — one yearly fee is cheaper than a single month on most rivals.
