ThreadWeaver

Every chat UI makes you choose between keeping the good thread and trying a different approach. So you open a second tab, then a third, then lose track of which one had the useful answer.

ThreadWeaver is AI chat where the conversation is a graph. Fork from any message, run several directions in parallel, compare them side by side, and cherry-pick the good parts into a merged thread.

• Branch any conversation — fork from any message, not just the last
• Compare branches side by side and cherry-pick into a merge
• Per-message provenance — which model, from which parent, under which settings
• Multi-LLM: OpenAI, Gemini, Mistral, Llama and local models via Ollama
• MCP tool calling, so the conversation reaches the rest of the suite
• Rich markdown rendering, voice, sharing and hooks

Self-hosted · multi-LLM · built on AgentStateGraph

• AgentStateRouter — compare models, then route on what you learned
