Show HN: Llmcanvas.chat Tree-based LLM chat on an infinite canvas (llmcanvas.chat)

No one thinks linearly, yet current LLM interfaces still force you to, and it sucks.

So I built llmcanvas.chat. The name says it all; you can branch, regenerate across models and compare: all in one infinite canvas.

Every prompt and response is a node in the canvas and it brings ultimate flexibility on how you interact with the LLM, while keeping the old-school way of chatting linearly.

Bring your own keys, 4 providers supported: Anthropic, OpenAI, Gemini, and OpenRouter.

Try it: llmcanvas.chat. I'd love to hear your feedback.
