Rabbithole turns documents, questions, and answers into a branching canvas. Select what catches you, ask, and follow the answer as far as it goes.
select anything, ask anything.
Two ways in
Open the hosted app immediately, or connect Rabbithole to the terminal agent already doing your work.
Bring an OpenRouter key or point Rabbithole at an OpenAI-compatible local model such as Ollama. Your holes and settings stay in this browser.
OpenRouter requests go directly to OpenRouter. Local-model requests go only to the endpoint you configure.
Open RabbitholeInstall the MCP server and let your existing agent answer. Rabbithole supplies the local canvas, branching documents, and durable storage.
The server and canvas run on your machine. Documents and questions go only to the agent you already use.
