Show HN: Thought Canvas – Develop Ideas with AI (Mind Mapping)

I created Thought Canvas to explore ideas I've had but felt the standard AI chat interface was too linear and dense. The mind map layout used in the app reframes this human-AI workflow.

To use Thought Canvas, you start with an idea or area to explore and a few next branches are suggested by AI. You can continue along those suggested paths by clicking the green ticks. Or type in your own branches at any level by clicking the plus button to explore alongside AI.

It's early days, but I'm finding the app useful to explore ideas more broadly, using AI for inspiration and refining my own thinking. Please feel free to use and provide feedback on how it can be improved. Thought Canvas is mostly built with Claude Code using the awesome React Flow library. Haiku 4.5 is currently wired in for AI suggestions.
