Been using n8n for a while and kept running into the same
friction point — I wanted to quickly sketch out a workflow
idea without opening n8n, setting up a session, and going
through the full build process just to prototype something.
So I built a small standalone tool that runs entirely in
your browser. You paste your free Gemini API key, describe
what you want in plain English, and it generates n8n
workflow JSON you can import directly.
No server. No login. No n8n instance needed to generate.
Just open the HTML file and go.
Also included 5 ready-to-import workflow files for common
use cases:
- Slack → Google Sheets logging
- Gmail → Drive attachment backup
- RSS → Twitter/X auto-post
- Typeform webhook router
- Notion → email digest
Tested on n8n 2.x — nodes import correctly, you just
connect your own credentials after import as usual.
Useful if you’re prototyping ideas quickly, evaluating
workflows before building, or want a scratchpad outside
your n8n instance.
