My landlord is keeping my deposit for “wear and tear”. Can he do that?
Normally no — ordinary wear and tear is the landlord’s cost, not yours. Damage beyond that is different. Tell me what he listed and I’ll sort it into the two piles, then draft the letter back.
Draft it as a PDF I can send.

Where it runs

Six platforms. One app.

Not a flagship version and five compromises. The parts that have to behave identically are written once and shared by every one of them — including the Windows and Linux builds still on the way.
iPhoneThe whole product in your pocket, with Face ID in front of it.
iPadA real iPad app — your chats and the conversation side by side, not a stretched-out phone.
MacA native Mac app, built as its own thing rather than a phone app in a window.
AndroidSame encryption core as the iPhone app, so the two behave identically.
Coming soon
WindowsA proper desktop app for the machine you actually work on.
Coming soon
LinuxBecause the people who care most about this tend to be running it.
Why they cannot drift apartEverything that has to agree between devices — the encryption, the way messages are packed, the codes you use to verify each other — is one shared core that every app compiles against. Two of our own apps cannot quietly disagree about something that matters, because there is only one copy of the part that matters.
What you get

Everything you expect. None of the exhaust.

This is not a stripped-back “private alternative” that asks you to give things up. It is the whole thing — it just does not keep anything.
It makes real documentsAsk for a summary and get a PDF. Ask for the numbers and get a spreadsheet that opens. Built on your device, not on a server.
It knows what happened todayWeb search when you want it, off when you do not — set per chat or everywhere at once.
It remembers, on your deviceTell it something once. The memory lives on your phone, sorted on your phone, and you can bring your memories over from another AI.
Dictation that never leavesSpeech becomes text on the device itself. On a phone that cannot do that locally, we hide the microphone rather than quietly send your voice away.
A locked drawer for your filesKeep documents in the app, encrypted, and set them to destroy themselves after a day, a week, a month — or never.
Photograph a document, then ask about itPoint the camera at a letter or a bill and it becomes text you can question. You choose whether the picture itself is sent.

Only in the apps

The apps do something the website cannot.

Collaborate lets you bring other people into an encrypted chat — and pull the assistant in when you need it. It exists only in the apps, and there is a specific reason for that which we would rather explain than hide.

One subscription. Every device.

Buy it once and sign in anywhere — phone, tablet, laptop, desktop. Your chats sync between your own devices, encrypted the whole way, and never through anything we can read.First month free with code PRIVATE · cancel anytime
