Memory for your AI · imagined in 1945
Your AI is brilliant.
And forgets everything.
Memexa is the memory you own: a knowledge graph built from your notes and documents that Claude or ChatGPT can read, cite and tend — hosted in Europe, exportable forever.

Example scene: something is saved in one AI client — Memexa stores and links it via a tool call. Days later the same person asks another client and gets the answer with its source.
Scripted illustration of real tool calls.

The Memexa file
Three things worth remembering. Memexa remembers the rest.
File 01 · Remember
Your AI forgets you. Memexa doesn't.
Notes, documents, decisions — everything becomes a linked knowledge graph your AI searches and cites down to the page.
File 02 · Model-neutral
One memory, every AI.
Claude today, ChatGPT tomorrow, the next model after that. Models come and go — the brain stays.
File 03 · Yours
It belongs to you.
EU-hosted, all Markdown, export any time. And it tends itself instead of keeping you busy.
A look inside the brain
This is what knowledge looks like when it's connected.
Travel tips, lab results, recipes, project decisions, the garden: everything you save becomes a node — and Memexa draws the connections. Your AI follows them when you ask.
● Topic ▭ Note PDF document ◠ Person Example excerpt — your graph builds itself as you save.
The five-minute moment
Connect. Ask. “My AI knows me.”
No migration, no new tool to learn: connect your AI client once, toss in notes and PDFs — and from the first question on, your AI answers from your own material. With the source: document, page.
- 01 Connect — once, five minutes, no technical skills
- 02 Toss it in — notes, PDFs, links, decisions
- 03 Ask — every answer cites its source

Which tool did we evaluate for bookkeeping — and why did we drop it?

From the manifesto · 1945
“In 1945, Vannevar Bush described a machine that never existed: the Memex. Eighty years later we have machines that can think. But they don't remember.”
Tell your AI once.
From today on it remembers — in every client, with sources.
