ConvTree brings Git-style version control to LLM conversations, letting users create checkpoints and branch into new discussion paths without losing context.
Built on MongoDB Atlas, it stores chats as a conversation tree and reconstructs any branch using $graphLookup.
When histories grow large, Atlas Vector Search helps users find the right checkpoint using natural language.
Tech stack: Next.js, TypeScript, ReactFlow, MongoDB Atlas, OpenAI/Ollama.
