Twin

Twin is a free AI buddy for Mac that lives locally and reads your texts and calendar. It keeps data on your machine, not in the cloud, and you bring your own AI key.

Twin is launching as a free, open source Mac app that sits on your desktop and tries to act like a helpful sidekick instead of another chatbot tab. It catches you up on texts, keeps track of your calendar, talks back by voice, and nudges you before you forget something.
The part that stands out is where the data goes: nowhere public. Twin stores everything in a local DuckDB file, so the app is built around the machine it’s running on. No cloud. No account creation. That’s the pitch.
It also doesn’t ship with its own model access. Users bring their own Claude, GPT, Gemini, or Grok key, which makes Twin feel less like a giant platform and more like a thin layer of organization on top of tools people may already pay for.
That design choice says a lot. Product Hunt is full of apps trying to become the center of your digital life; Twin is leaning the other way, toward privacy and control, with the tradeoff that you’re wiring it up yourself. For people who want an on-device assistant and don’t love handing yet another service their messages, that may be exactly the point.
My take — AI-written commentary, not fact-checked reporting
The cleanest thing about Twin is also the rarest: it doesn’t pretend the cloud is a personality trait. Local-first AI is the sensible answer to all the “let us remember everything for you” enthusiasm that keeps tripping over privacy. A small miracle, really — an assistant that starts by minding its own business.
