You have notes scattered across five apps, a chat history full of half-formed ideas, and a browser with 47 tabs "for later." Eigen Mesh is built for exactly that mess.
It's an AI-native second brain. You drop thoughts, links, plans, and screenshots in. It remembers them, organizes them in the background, and makes them available to every AI tool you use — from one place.
Here's the whole idea in 60 seconds.
The one-line pitch
Your memory. Not theirs.
Right now, every AI assistant keeps its own private copy of what you told it. ChatGPT remembers one version of you. Claude remembers another. Your notes app remembers a third. The real you — the one with the actual ideas — is split across a dozen silos you don't control.
Eigen Mesh flips that. Your memory lives in one place that you own, and the AI tools you already use can plug into it.
What you actually do
Nothing fancy. No folders. No tags. No "system" to maintain.
You just drop things in. A half-thought from the shower. A link a friend sent. A screenshot of a whiteboard. A voice memo on the way to the train. Whatever.
Eigen Mesh takes it from there.
What happens in the background
This is the part most apps skip, and it's the part that matters.
Every capture runs through a small pipeline:
- Capture — raw text, image, audio, link, anything.
- Background enrichment — Eigen Mesh cleans it up, extracts the key points, connects it to related thoughts you've already saved.
- Overnight consolidation — while you sleep, it re-reads your recent captures, tightens the links between them, and surfaces patterns. You wake up to a memory that's smarter by morning.
You don't do any of this manually. It just happens.
When you need it again
Later, you ask. "What was that framework for thinking about pricing I mentioned in March?" Eigen Mesh doesn't just keyword-search your notes. It uses a hybrid retrieval approach:
- Search — the literal words you wrote.
- Meaning — what you meant, even if you phrased it differently.
- Graph — how this thought connects to the others around it.
So you find the idea, not just the file.
Why this is different
Most "second brain" tools are fancy filing cabinets. You do the filing. You maintain the tags. You remember which notebook you put it in. Six months in, the system collapses under its own weight and you start a new one.
Eigen Mesh assumes you won't maintain anything. The maintenance is the product. You capture; it organizes. You forget; it remembers.
Who it's for
- People who think in fragments, not folders.
- People who use more than one AI tool and are tired of re-explaining themselves.
- People whose best ideas show up at the worst moment and need somewhere to land.
- People who want their memory to belong to them, not to a chatbot company.
If you've ever closed a chat window and immediately thought "wait, I needed that," Eigen Mesh is for you. If you've ever had the same good idea twice because you forgot you already had it, Eigen Mesh is for you. If your notes app has a graveyard of half-started systems you abandoned by week three, Eigen Mesh is for you.
A quick example
You're walking to the train and you have a thought about a project you've been stuck on. You don't have time to write it up properly. You drop a one-line voice memo into Eigen Mesh and forget about it.
Over the next few hours, in the background, Eigen Mesh transcribes it, connects it to three earlier thoughts about the same project, and notices it contradicts one of them. That night, during consolidation, it pulls those into a small cluster and flags the contradiction.
The next morning you open Eigen Mesh and there's a short summary waiting: "You've been circling this project. Here's what you've said about it. By the way, last night's note disagrees with Tuesday's — want to reconcile?" That's not a search result. That's a memory doing the work of remembering.
What it costs to try
You start with 100 free credits when you sign up — roughly 100 to 150 thoughts worth of capture, enrichment, and retrieval. No card required.
If it sticks, it's €3.99 a month. Less than a coffee. No usage surprises, no token math, no "did I just spend $12 asking a question?" anxiety.
What it doesn't do
It doesn't train on your data. It doesn't lock you in — it's open source under Apache 2.0, and you can self-host the whole thing if you want. Your memories are encrypted at rest and isolated per user. Servers are in the EU, under GDPR.
Your memory stays your memory.
Try it
If any of this sounds like the thing you've been missing, get early access and drop your first thought in. You'll know within the first 100 credits whether Eigen Mesh fits the way you think.
