README Excerpt

**Persistent, searchable memory for every AI tool you use — solo or as a small team.** > 📖 **[Read the full documentation →](https://srnichols.github.io/OpenBrain/)** Every AI conversation starts from zero. You explained your architecture to Claude last week, made a caching decision in ChatGPT yesterday, captured a pattern in GitHub Copilot this morning, and now Cursor has no idea about any of it. Your knowledge is scattered across platforms, locked inside sessions that expire.
