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.
