Show HN: TrAIn of Thought – AI chat as I want it to be
two-sandwich Tuesday, March 03, 2026My conversations with LLMs branch in many directions. I want to be able to track those branches, revert to other threads, and make new branches at arbitrary points. So I built my own solution to it.
It's essentially a tool for non-linear thinking. There's a lot of features I'd love to add, and I need some feedback before I take it anywhere else. So, I'm listening to whatever you're thinking is broken.
Basic feature set: - Branching conversations: follow up from any node at any time, not just the latest message
- Context inheritance: when you branch off a node, the AI gets the full ancestry of that branch as context, so answers are aware of the whole conversation path leading to them.
- Text-to-question: highlight any text in an answer to instantly seed a new question from it.
- Multi-provider AI: compare and adjust responses from OpenAI, Anthropic, and Google Gemini.
- Visual graph: the conversation renders as a React Flow graph with automatic layout, so you can see the whole structure at a glance.
- Shareable links: your entire chat is compressed and stored in the URL. Everything is local (well, except the API calls).
- Branch compression: long branches can be collapsed into a summary node to keep the graph tidy.
