MEMORY.md, a Redis-backed agent memory you can watch live

An AI SDK agent whose entire long-term memory is one Markdown file, MEMORY.md. The agent reads it, greps it, and writes to it with ordinary file-style tools. The "file" is virtual and lives in Upstash Redis.

Memory model inspired by https://docs.openclaw.ai/concepts/memory.

How it works

┌──────────────┐   tools     ┌──────────────┐   string key   ┌─────────────┐

Run it

1. Add your Anthropic key and Upstash Redis credentials to .env:

   UPSTASH_REDIS_REST_URL=
   UPSTASH_REDIS_REST_TOKEN=
   ANTHROPIC_API_KEY=sk-ant-...
   

2. Start it:

   bun dev
   

   Open http://localhost:3000.

3. Tell the agent something about yourself ("I'm Josh, I prefer TypeScript") and watch it write to MEMORY.md on the right. Ask "what do you remember?" in a fresh message and it reads the file back. Reset demo wipes it between takes.
