Gap 01 · Between your tools
Your AI tools don't talk to each other.
ChatGPT for one thing, Claude for another, Cursor in your code — and each starts from zero. What you taught one is invisible to the next.
Memory for your AI · imagined 80 years ago
A memory for your AI that comes with the page number
Memexa is the memory you own: a knowledge graph built from your notes, documents and scans. Claude or ChatGPT read it, cite it down to the page and keep it in order — EU-hosted, exportable forever.

Example scene: a scanned insurance PDF lives in Memexa. Asked about the deductible, the AI answers with the amount and cites the source — document, page 4 — while the passage is highlighted in the scan.

Two gaps, every day
You keep explaining things that are already written down
Gap 02 · Between AI and your knowledge
Your knowledge sits where no AI can see it.
In PDFs, email threads, scattered notes. It's written down already — no AI can read it there. So you explain it a third time.
One thing closes both gaps: a memory every client can read — and that belongs to you.
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.
What it's for, day to day
This isn't about tidying up
It's about having somewhere that holds what concerns you — and an AI that can reach it when you ask.
You askMemexa supplies
“Is the laptop still under warranty?”
Purchase date and retailer, from the invoice sitting there as a scan
“Which contracts run out this year?”
The dates are in documents you already added
“Draft a reply to this letter from the tax office.”
Prior correspondence and reference numbers, without you digging them out
“What did I decide last time, and why?”
Not just the outcome — the reasoning
The longer you collect, the sharper the answers.
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.
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
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.

Getting things in
Four ways in, and none of them feel like work
Upload it or type it
PDFs, notes, decisions — straight into Memexa.
Your own email address
Every account gets one. Forwarding is enough; the rest happens by itself.
A photo or a scan
Photograph the invoice. Text recognition turns it into searchable text you can cite by page.
Moving from Obsidian or Notion
Upload a ZIP — internal links survive as edges in the graph.
An honest comparison
Not built-in memory. Not a context file. Yours.

| Open source | No — export is open | App no, files open | No | No |
| Reads scans & PDFs (OCR) | Yes | “clunky” — community's words | Attachments, superficially | No |
| Page-level sources | Yes | No | No | No |
| Any MCP client | Yes — one URL | Via community servers | No | No, tied to the tool |

Before you ask
The questions that always come
What if you shut down?
Straight answer: Memexa isn't open source, so the community couldn't keep the service running. What we can commit to is in the contract rather than the marketing: we can only terminate the Free plan on three months' written notice (§ 7 of the terms), paid plans at the end of the billing period on one month. And the export works from day one — you don't have to take our word for it, you can try it immediately.
Why not just use Obsidian?
If your knowledge is text you write yourself: use Obsidian, it's excellent at that — and your vault imports later as a ZIP with wikilinks intact. The difference is documents. In the Mac Power Users forum, an Evernote emigrant calls Obsidian “good at text only”, with getting receipts and scans in being “clunky”. That exact part is Memexa's core: scans go through OCR and become citable down to the page.
Where does my data live — and can I leave?
The exit first: everything exports as Markdown, one click, complete — the graph is an index, not a lock-in. And inside: servers, database and documents live with Scaleway in Paris; AI processing runs through Mistral AI, also Paris. An EU company address is not EU hosting — which is why we publish names and places.
What does it cost — and what do you live on?
Free stays free forever; Pro is €12, Power €29 a month. Memexa is bootstrapped — no investors, your subscriptions are the entire business model. Which is why Memexa won't go the way of Pocket, Omnivore and Rewind: there's nobody to pull our plug.
Does it fit my stack?
Memexa is an MCP server — the open standard spoken by Claude, ChatGPT, Cursor and practically every new AI client. One URL, one browser sign-in, done. No per-tool plugin, no API keys, and the next client you try can read along immediately.
How do I know it works?
The demo above is scripted — the Free plan isn't. Connecting costs nothing and needs no credit card. The first question you ask about your own uploaded PDF answers this better than any landing page.

Verifiable
An EU company address is not EU hosting
So instead of badges, here are names and places — every claim checkable.
Data center
Scaleway, Paris (fr-par) — servers, database, object storage. Named, not just “EU”.
AI processing
Mistral AI (seated in Paris), processing in the EU — OCR, embeddings, distillation. No US model provider sees your content.
The exit
Markdown export, one click, complete — before you have to ask.
Error tracking
Self-hosted (GlitchTip on our own EU infrastructure) — no third-party telemetry.
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.”

From today on it remembers — in every client, with sources.
