Cortex — Persistent Semantic Memory

Cortex — Persistent Semantic Memory

Persistent semantic memory for AI assistants. Same memory from Claude, ChatGPT or any MCP client: your AI remembers your work, decisions and conversations across sessions, devices and models. Unlike plain RAG or note archives, every write passes a server-side **quality gate** that rejects redundant memories (~80% of proposals in production), contradictions are tracked as first-class objects instead of being silently swallowed, and every answer can cite its sources. - **Zero setup** — hosted remote MCP server, OAuth sign-in, trial space auto-created on first connection (30 days, no credit card) - **Governed writes** — novelty filter, typed claims, deduplication at write time - **Conflict tracking** — contradictions surfaced with warnings, never hidden - **Multi-model** — one memory across Claude, ChatGPT and any MCP-compatible client - **EU infrastructure** — export and delete your memories at any time Listed on the official MCP registry (io.github.FilippoPilo/cortex).
