Model-neutral memory · MCP-native
Not another memory MCP. A knowledge system that tends itself.
Notes and documents become a linked knowledge graph with hybrid search and page-level provenance — readable and maintainable by any MCP client via OAuth 2.1. Reasoning runs on your model. Hosted in the EU. Everything exports as Markdown, any time.
Free plan, no credit card. Works on every Claude plan.

Sign in once in the browser — OAuth 2.1, no tokens to copy. The endpoint is the same for every client.
Architecture
What "not a scratchpad" means
Document pipeline
PDFs are OCR'd, chunked, embedded and distilled into linked notes — search hits carry page-level provenance.
Typed graph edges
Notes, people, projects and sources are linked with typed relations, not a flat tag soup.
Auto-linking
New captures are connected to existing knowledge automatically — no manual gardening.
Weekly digest
A summary of what changed, what connected, and what's left open. The graph tends itself.
Architecture in one line: your model reasons, Memexa is the substrate.
Compare honestly
Against thin memory stores
| Memexa | Typical memory stores | |
|---|---|---|
| Works across AI clients | Any MCP client | Single vendor, or plugins |
| Ships its own model | No — bring your own | Bundled (you pay twice) |
| See & edit every memory | Full notes UI + graph | Opaque store or settings list |
| Export | Markdown, one click, complete | Varies; often JSON dumps |
| Hosting | EU, GDPR | US by default |

Ownership & EU
Your data stays yours
Hosted in the EU under the GDPR. Every memory is a Markdown file you can read, edit and export — the graph is an index, not a lock-in.
