A calm place for notes, journals and to-dos — with AI that summarizes, finds and plans for you. Everything is encrypted on your device and works offline.
Free to start. Sync across all your devices with Pro. Android beta first, iPhone later.
Capture & find
Type, talk or snap a photo. Search by meaning, right on your phone — Tessera finds the note you’re thinking of even when you don’t remember the words.
Daily brief
Each morning, Tessera turns your notes into a short stack of cards. Go through them one by one, add what matters to today, and push the rest to later.
Tasks
Put “get quotes for the shelving” on a checklist in a note and it becomes a task. Break big ones into steps, give lists a deadline, or make your shopping list reset every Saturday.
Security
Every note is encrypted on your device before it syncs. Your keys never leave your devices — we can’t read your notes, and neither can anyone else.*
Pricing
Free keeps everything on one device. Pro adds encrypted sync across your devices, more cloud AI and cloud storage.
Available when the app launches
Available when the app launches
Local prices and taxes in Google Play and Apple App Store may vary; the price shown in the store is final. Subscriptions are managed in the app — cancel anytime. On-device encryption and the app lock are always free.
No. On Free your notes never leave your device. With Pro they're encrypted on your device before they sync. The one optional exception is cloud AI, and only if you turn it on.
Most AI runs on your phone. Cloud AI is optional and off by default. If you turn it on, it sends only the passages a request needs, over an encrypted connection, to providers that don't train on your data. On phones without on-device AI it asks you first, every time, and shows you what would be sent. You can turn cloud AI off anytime.
Pro is bought in the app through Google Play (and the App Store on iPhone, later), so you manage or cancel it where you manage your other subscriptions.
Nothing is deleted. Sync pauses, every device keeps its full local copy, and you pick one device to keep using on Free. Your encrypted cloud copy is kept for 180 days, so sync picks up again if you come back.
With your Google or Apple account. Both options work on Android and iPhone, so switching phones never locks you out. Google and Apple only confirm who you are; they never get access to your notes.
No. Free is one device, and your notes stay on it. Pro adds end-to-end encrypted sync across your devices.
With Pro, sign in on the new phone and restore with your Recovery Kit or another linked device. On Free the phone holds the only copy, so keep a backup with the built-in export. Either way, nobody (including us) can decrypt your notes without your keys.
After the Android beta. Join the waitlist and pick iOS to hear when it is ready.
The app is in English at launch, and you can write notes in any language; AI features answer in the language of your note. German, French, Spanish and Turkish are planned for the app.
Free to start. Pro adds encrypted sync across your devices and more cloud AI for €4.99 a month.
Your notes are end-to-end encrypted on our servers, so we can't read them. Cloud AI is optional and off unless you turn it on. If you do, the parts of your notes a request needs (for example, a few passages you ask about) are sent through our servers to an AI model provider, with personal details like email addresses and phone numbers masked. Our servers only relay these requests and don't log or store them, so apart from the model provider processing a request, nobody can see what was in it. AI that runs on your phone, search and voice transcription never send anything.
