CallVault
LiveA conversation vault, not an AI notetaker.
- The problem
- Call recordings produce signal that dies in “I'll review the transcript later,” and every notetaker traps it in its own silo.
- The build
- Record everything, transcribe, and expose the corpus to any model through a 40-tool MCP server. Solo: 3,302 commits, ~214K lines TypeScript, 283 migrations, 79 edge functions, 277 unit + 67 e2e tests.
- The decision that mattered
- In January 2026 I deleted ~39K lines of in-app RAG and went MCP-first — let Claude be the AI, make the data AI-ready.
- Adoption
- Three organizations, 580+ calls.
- What I believe
- The durable value of AI products is in the data and the interfaces to it, not the chat window.
