A personal RAG database you build from chat, so AI creates work that sounds like you.
MyAITwin is a personal RAG database and semantic search engine you build and control from inside your AI chat. No dashboards, no upload flows, no engineering. You store something worth keeping in a conversation, and your twin grows.
It holds two things and uses both: your knowledge, what you know, and your skills, how you express things. Store a voice note, a document, a URL, or a thought, and it is captured in seconds and tagged automatically. Ask what your principles are or what you decided last month, and it comes back in your own words with the source and date cited. When you create, the output starts from your knowledge and your voice, so it sounds like you rather than generic AI.
It runs on production infrastructure (Supabase for structured data, Pinecone for vector embeddings) and connects as a custom MCP connector to Claude Pro, Claude Team, and ChatGPT Pro. Your data lives in your own namespace, is never used to train models, and can be deleted instantly. Free during early access. Setup takes under two minutes.
MyAITwin is a multi-tenant knowledge management MCP server with generally sound architecture and proper OAuth authentication. However, several security concerns emerge: environment variable exposure risks in the test/admin scripts, inadequate input validation in some areas, and insufficient rate-limiting documentation. The cross-tenant isolation testing is thorough, but the production code relies on downstream validation. Permissions align reasonably with a productivity tool accessing knowledge databases and APIs.
