What makes it different

◈

Model-agnostic

Claude, ChatGPT, Gemini, Mistral — your memory isn't locked to any platform.

◎

Zero transcript storage

Raw conversations are processed in memory and discarded. Only distilled facts persist.

◉

Semantic retrieval

Memories are fetched by meaning, not keywords. Ask about your Go project and get everything relevant.

◇

Contradiction resolution

Moved cities? Changed jobs? Havril detects conflicts and updates your profile automatically.

✦

Native MCP for Claude

Claude calls Havril as a real tool mid-conversation. No prompt injection. No hacks.

⊕

Importance scoring

Memories that matter stay. Stale context fades. The engine keeps your profile accurate over time.
