Q: Can I edit the generated flowchart?

Yes. Click any node to rename it or change its shape. You can also edit the Mermaid code directly in the output panel and re-render.

Describe any process in plain English. Gemini converts it into a structured, editable flowchart in seconds — no diagramming experience needed.

How to write a strong prompt

The more explicit your prompt, the better Gemini can structure it. Include:

A clear starting point — what triggers the flow? ("Start when a user submits the form")
Named decision branches — include both paths explicitly: the success path and the failure path
Action verbs at every step — validate, check, send, notify, redirect, retry, reject
Explicit end states — where does each branch terminate?

Example prompt

Customer refund approval

"Create a customer refund approval flow. Start with a refund request. Check if the order is within the return window — if not, reject and notify the customer. If yes, send the item to quality review. If approved, process the refund and notify the customer. If rejected, send an explanation and close the request."

FAQ

Can I edit the generated flowchart?

Yes. Click any node on the canvas to rename it or change its shape. You can also edit the Mermaid code directly in the output field and re-render. The Manual Builder tab lets you add or remove nodes entirely.

Do I need a Gemini API key?

Yes, for AI generation. You can get a free key from Google AI Studio at aistudio.google.com. The free tier supports hundreds of generations per day. The Manual Builder works without any key.

Is this only for Mermaid users?

No. Mermaid is the rendering engine under the hood, but you never need to write Mermaid syntax. The app generates it for you and renders a visual diagram. You can export as SVG or PNG if you don't need the code.

Is my API key sent to your servers?

No. Your key is stored only in your browser's localStorage and sent directly to Google's Gemini API. AI Flowchart Studio's servers never see it.
