I kept hitting the same friction point while working
with n8n — every time I had a quick workflow idea,
I had to open my n8n instance, hunt for the right
nodes, wire them up manually, just to prototype
something that might not even work.
So I built a small tool to fix that.
What it does
A single HTML file that runs entirely in your browser.
You paste your free Gemini API key, describe your
workflow in plain English, and it generates n8n-
compatible workflow JSON you can import directly.
No server. No backend. No n8n instance needed to
generate the workflow.
How it works
The tool sends your plain English prompt to the
Gemini API with a system prompt engineered to output
valid n8n workflow JSON — correct node types,
parameters structure, and connections format.
The key challenge was getting Gemini to output JSON
that n8n actually accepts on import. n8n's workflow
JSON has a specific structure — nodes need correct
typeVersion, position arrays, and the connections
object needs to map node names exactly.
After several iterations the output imports cleanly
with nodes and connections intact. Credentials are
intentionally excluded — n8n never stores credentials
in workflow JSON anyway, so users connect their own
after import as usual.
What's included
- The HTML generator tool (BYOK Gemini API)
- 5 ready-to-import workflow JSON files:
- Slack → Google Sheets logging
- Gmail → Drive attachment backup
- RSS → Twitter/X auto-post
- Typeform webhook router
- Notion → email digest
Try it
If you're an n8n user who wants a faster prototyping
experience outside your instance, the pack is
