I built NodeTrellis, a lightweight web app that converts ChatGPT-generated JSON into an interactive mind-map. It’s 100 % client-side—no log-ins, no servers, completely free.
How it works
1. Enter a topic (or paste any URL) and click Copy Prompt. 2. Send that prompt to ChatGPT and copy the JSON it returns. 3. Paste the JSON back into NodeTrellis and hit Render Map. 4. Instantly get a draggable, zoomable map you can edit, undo/redo, and export.
I’d love your feedback, bug reports, and feature ideas. Thanks for checking it out!
