Building a persistent AI 'digital twin' with Convex
Convex is a backend platform for AI agents that stores conversation history and state permanently. 'Convex twin' explores building a persistent AI agent that mirrors a real user or system using this platform. It's a practical idea worth knowing for anyone building AI agents.
Convex bundles a database, real-time sync, and async workflows into one backend platform. One of the hardest problems when building AI agents is state management — keeping track of what the agent remembers and making sure it can pick up where it left off. Convex handles this automatically by storing threads, messages, and memory so multiple agents can share and build on the same context.
A 'digital twin' originally meant a software copy of a physical system. In the AI agent world, it means a persistent agent that learns how a specific person or system behaves and can respond or act on their behalf. Convex's permanent state storage and real-time update features make it well-suited infrastructure for building this kind of twin agent.
Key points
- Convex automatically persists an AI agent's conversation history and state
- Multiple agents can share the same thread and collaborate
- A 'digital twin' is a persistent AI agent that mimics a specific person or system
- Convex pushes real-time updates to clients without manual WebSocket setup
- It is open-source and lets you write backend logic in TypeScript
