Capture
Say it once, never lose it
Talk or type, whenever it hits. No folders, no tags. It becomes memory — instantly, and smarter by morning.
Eigen Mesh Your memory. Not theirs.
Your second brain shouldn't belong to a company that mines it for ad revenue. Eigen Mesh is open source, less than a coffee a month, and yours forever.
Philosophy
A thought only matters because you kept it.
Most "AI memory" works by quietly mining your emails, transcripts, and PDFs — deciding for you what's worth remembering. Eigen Mesh works the other way around: you say it, you meant it, it's saved.
That one deliberate act is worth more than any amount of passive surveillance. It's what makes the difference between an assistant that has data on you and one that actually knows you.

"Open source" doesn't just mean free — it means anyone can read the code that handles your memories, including the people who make sure we can't do anything shady with them.
GDPR Compliant
Your data is protected by EU privacy law.
Eigen Mesh was built from the ground up on the principles of the EU General Data Protection Regulation. Not a bolted-on GDPR badge — but the foundation itself.
Nobody else can read your thoughts.
Your notes are stored encrypted at rest in the database — not even we can just read along. What you think and write stays yours.
Nobody else can see your memories.
Row-level isolation — every account sits in its own isolated row on the server. No other user can ever read your memories.
Your data stays in the EU.
Servers in the EU: your data is processed exclusively within the European Union — no cross-border transfers, no Schrems II risk.
We have nothing to hide.
Open source under Apache 2.0 — anyone can audit the code. What we say is what we do.
Why Eigen Mesh
Your thoughts stay yours.
Your data, your rules.
Your memory lives in plain storage you control. No hidden copies, no silent sync to a vendor cloud.
We don't train on your data.
Nobody else reads your memories. Not for ads, not for training, not for "improving the product."
Open source, audited by anyone.
The full code is public, so anyone can verify we're not doing anything shady with your thoughts.

About Eigen Mesh
There are memory tools built as kits for tinkerers — wire up your own agents, your own pipelines. That's a real thing, and OpenBrain, mem0 and others do it well. We're not competing with them. Eigen Mesh is a product, not a framework.
We don't believe in quietly pulling meaning out of your emails, transcripts and PDFs. That's not how a mind works. A thought matters because you had it, felt it was worth keeping, and chose to save it. That deliberate act is what builds a real understanding of you — so we make capturing it the whole point, not an afterthought.
You can start using it today with nothing to set up. Your data stays yours: export it, delete it, and read every charge in a transparent activity log. Open source under Apache 2.0 — run it yourself, or use our hosting for €3.99 a month.
What you get
- Capture a thought in plain words — the moment you decide it's worth keeping
- A transparent activity log that lists every charge
- Export or delete your data whenever you want
- Works with the AI tools you already use
FAQ
Common questions
A personal memory service for your AI. You save thoughts in plain language, we organize them in the background, and your AI assistant can find them when you ask — across any tool you use.
Those products remember you inside their own apps. The moment you switch tools, your memory stays behind. Eigen Mesh remembers you across every AI you use — and the data lives with you, not with a vendor.
Yes. Eigen Mesh is open source under Apache 2.0 — the same codebase powers both Eigen Mesh and self-hosted deployments. Source is on GitHub at github.com/hikaru90/eigen.
No. Write naturally when you capture something. Sorting, labels, and connections happen automatically after you save.
New accounts get 100 free credits — enough for about 100–150 thoughts. To keep capturing on managed hosting after that, subscribe for €3.99/mo (less than a coffee) with about 150 thoughts/month included. Or self-host the open-source software and bring your own keys. Cancel anytime.
Yes. Self-host the open-source software for full control, or use Eigen Mesh directly if you prefer not to manage servers. Either way, your data stays yours.
Your raw notes stay in your database. We never paste hidden copies of your full memory into AI prompts—only the text needed to answer your question.
No. Your memories are kept separate from other users' accounts, with strict access rules on the server.
Your team already has the knowledge. It's scattered across a hundred chats.
We're looking for early adopters for Eigen Enterprise: one place where your team's projects, timelines, chat and document storage actually connect. No dashboards nobody opens — just the knowledge your team already has, findable. Get in touch and be the first to hear when we launch.
