OBS. This tool still works, but I now recommend a simpler approach: create a copy of your Power Automate flow and use the Power Automate Tools Chrome extension to paste and edit JSON directly instead of importing and exporting solutions.
Generate Power Automate Flow with AI.Describe the flow you want, let AI draft it and get a solution.zip with your flow that works (or needs only minor tweaks after import).

Step 1: Upload your unmanaged solution (.zip)

In Power Apps, create a new unmanaged solution with your preferred prefix. Add a new simple flow or copy an existing flow (don't add active production flows), export the solution as a zip, then upload it here.

Step 2: Describe your flow

Step 3: Review generated flow JSON
