Write like no one's watching. A calm place to write, organize, and think — with an AI you can talk to about your own notes. No account, no cloud, nothing leaves your device.

We believe the most personal software shouldn't live in someone else's cloud. localhost/AI builds focused apps that run AI entirely on your device — your notes, your money, your world, staying with you.
We believe privacy isn't a setting — it's an architecture. Nothing leaves the device, because there's no server for it to leave to. The model comes to your data, never the other way around.
We believe a focused app that does one thing for one person beats a sprawling platform. Each app is a specialist that knows your world and works offline, on your terms.
We believe you should own the intelligence you rely on. No accounts you can be locked out of, no subscription holding your files hostage. It runs whether or not we're around.
Every app shares the same on-device foundation — then adapts it to a corner of your life that deserves to stay private.
Write like no one's watching. A calm place to write, organize, and think — with an AI you can talk to about your own notes. No account, no cloud, nothing leaves your device.

Your money, on your phone. Track spending, snap receipts, and ask AI about your finances — all on your device. No bank logins, no account. Import a statement and it reads it locally.

We're building the next private, on-device app in the family. Same idea: your most personal data, an AI that helps, and nothing ever leaving your phone.
Our apps are powered by QVAC, Tether's open-source engine for running AI directly on your phone — no servers, no accounts, nothing sent away. We take that foundation and shape it into apps built around one person's world.
The engine that runs the AI on your device is QVAC. The apps, the design, and the way it all feels are ours.
We're building in the open and looking for early users, testers, and collaborators who care about private software.
