Frequently Asked Questions

What presets are available?

Full-Stack Web, Next.js App, Python/ML, Java Spring, Go App, Android Kotlin, Flutter, and DevOps/Infra. Each preset selects the most relevant stacks for that project type.

How does smart deduplication work?

When multiple stacks share the same pattern (e.g. both Node.js and React ignore build/), only one instance appears in the output. This keeps the file clean and readable.

Can I add a project name?

Yes — enter a project name in the input at the top of the settings panel. It appears as a comment in the output header: # Project: YourName.

Is the output suitable for team use?

Yes. The generated file is designed to be committed to your repository. All team members will share the same exclusion rules automatically.

How do I use Custom Rules?

Click "✏️ Custom rules" to expand the editor. Type any patterns (one per line). They are appended as a separate section at the end of the output file.
