Nothing to sign up for
Install it and it works. No account, no profile, no password, no email address handed over to use the app itself.
Personal OS · Android · Waitlist
The renewal, the appointment, the payment that changes next month, your mother's flight number — it all arrived in a text or an email, and it all scrolled away. SynexisOS reads your texts and your email, remembers what matters, and keeps every last byte of it on your device.
First build goes to this list before anywhere else. One email when it's ready — no newsletter, no drip, one-click unsubscribe.

What you see
Reading, understanding and remembering all run on the handset.
Not one network request happens between those two panes.
Local-first memory
Every assistant you've been offered asks for your texts and your inbox, and then takes them somewhere. SynexisOS is built the other way round: the reading happens on your phone, the memory is a file on your phone, and there is no second copy on a server we own. Turn off the network and it keeps working — because it was never using it.
Install it and it works. No account, no profile, no password, no email address handed over to use the app itself.
Capture, extraction and your memory all run on the handset. No signal, no Wi-Fi, no problem — the product doesn't notice.
Your memory is a database on your phone. Wipe it in one tap and it's gone — there's no copy on our side to go chasing.
Not a policy we could quietly rewrite in an update. In the local tier they never reach us in the first place, so there's nothing to hand over, sell or leak.
No ads. No data sale. No ad-tech SDK riding along in the app. This page has no tracker and no third-party font on it either — view the source.
Want your list in a browser, or to survive losing the phone? That's one clearly-labelled setting, off by default, and it stays off until you choose otherwise.
Most apps promise to protect your data. We'd rather never hold it.
What it takes off your plate
Texts and email come in on their own — you don't retype a thing. And when something reaches you another way entirely, a phone call, a letter, a conversation in a corridor, you add it yourself in a couple of taps and it sits in the same list as everything else.
Permits, insurance, passports, MOTs, free trials about to bite. They arrive months early, in a message you read once and never saw again.
Rescheduled, delayed, brought forward. The new time lands in a message; the old one stays in your head. SynexisOS keeps the current one.
Direct debits going up, subscriptions renewing, bills falling due. Amounts and dates pulled straight out of the text, on your phone.
The birthday, the school closure, the favour your sister asked for on Tuesday. The half of your inbox no productivity app has ever had a home for.
Where this goes
Dates are simply the first thing a system can be trusted with. Once your phone genuinely understands what's arriving — and keeps it to itself — the renewals, the bookings, the chasing and the paperwork all become things it can carry for you, with your say-so and nobody else's.
A personal operating system, in the plain sense of the phrase: the layer that runs the logistics of your life. Built local first, so that trusting it with more doesn't mean giving more away.
Early access
The first build goes out to this list, on Android, before it goes anywhere public. Put your address in and you'll hear the moment there's something to install.
We keep your address and the date you gave it. Nothing else, no tracking, no sharing. Android first — reading your texts is part of the mechanism, and iOS doesn't allow it.
