The desktop app holds your archive, reads your handwriting on your own hardware and serves the local MCP server. The Boox app captures raw pen strokes at 5 ms. Both run today — what isn't finished is the signed, notarised installer, and we'd rather say that than hand a warning dialog to people who came here for the security posture.

Behind the two above
The native capture app. Raw Onyx pen strokes with pressure, ink latency measured at 5 ms on a Go 10.3 Lumi — down from ~30 ms in the browser. Installs as a normal APK; there is no Play Store listing because Boox devices sideload anyway.
Held until device pairing is finished — see below
A writing surface that runs in your tablet's own browser — reMarkable, Supernote, an old iPad, anything with a pen and a browser. Nothing to install, nothing to sign. About 30 ms ink latency instead of 5, and it produces exactly the same .ink strokes the native app does.
This ships with the desktop app: it's served by your own computer, on your own network, so it arrives when the desktop build does.
Minimum OS versions and exact app sizes are published with the first build — we don't have them measured yet and won't guess.
Not a marketing hold. Two specific pieces of engineering, both nearly finished, both worth waiting for.
An unsigned binary makes macOS and Windows warn your users that the software is untrusted. For a product whose entire argument is about handling your most private data, the first thing you see cannot be a security warning. Certificates are being sorted.
The sync between tablet and computer currently filters by local network address and nothing more. That stops a stranger on café wifi. It is not yet a pairing handshake, and we're not shipping it into strangers' home networks until it is.
gemnotes runs its models on your hardware. That's the privacy promise, and it's also a real cost that lands on everyone — including people who never pay us anything.
About 10.9 GB of model weights on first launch, plus room to work. We're actively trying to get to one model instead of two, which would roughly halve it.
We don't yet know whether 8 GB is enough, and that number decides who this product is actually for. If you're on 8 GB, tell us below — it's genuinely the most useful thing you can send us.
The tablet doesn't read handwriting by itself. Your computer has to be on and on the same network when you sync. A real constraint, and one that rules some people out.
Not a newsletter and not a drip sequence — one message when the button above turns black, and nothing in between.
