Configure your AI programming twin in our website, then plug it into editors like Cursor, GitHub Copilot, Cline, Lovable, Macaly
It will program in your style, respect your rules, and use your design system components.

You'll see a live preview of what it learns and how it talks like you.

Use Cases for Developers

You don't need a hundred apps, tools, or dashboards. You need more time to focus on meaningful development.

Code reviews in your voice

Automated PR reviews that match your style and standards

Drafting commit messages or PR descriptions

Consistent, clear commit messages following your conventions

Responding to issues or questions on GitHub

Handle bug reports and feature requests professionally

Handling repetitive Slack threads

Auto-respond to common questions and status updates

Why it matters

Most devs spend 80% of their time on:

• Rewriting similar responses in PRs

• Attending redundant standups

• Commenting on the same type of bugs

• Chasing down specs or managing side channels

We flip that. Let your avatar take care of the busywork, so you can ship, think, and build.

🔧 Built for Engineers

It sounds like you.

Your voice, your thinking, your patterns—fine-tuned by learning from your GitHub, Slack, and code history.

Use it anywhere you work.

Drop it into your GitHub repo, Slack workspace, VSCode, or even use it on calls and demos.

Full control.

You decide what it can do, see every interaction, and tweak its behavior using human language.

Text-based, open, and dev-friendly.

Everything runs on plain-text logic called Book, interpreted by the open-source PromptBook Engine. No no-code walls, no vendor lock-in.

Start in seconds.

Import your GitHub, Google, or Slack data—or configure manually. It's up to you.

Own it.

It's open source. You can host it yourself or move your data anytime.
