A private AI twin that lives on your phone, learns only from what you tell it, and answers in your own words — or stays honestly quiet. Nothing you write ever leaves your device.
Most AI answers by guessing the next likely word — which is why it can sound confident and be wrong. SelfTwin is built the opposite way. It reads what you've written, finds the truest thing you actually said, and gives it back to you — worded the way you would say it. If your own words don't hold an answer, it tells you so instead of inventing one.
No stiff templates, no “As an AI…”. Ask a question and your twin replies in a real sentence — your phrasing, flipped to “you”. A person, not a form to fill.
verbatim · person-awareWhen your words don't hold the answer, it says so — plainly. That single rule is what makes a twin trustworthy: everything it tells you, you can trace back to something you truly wrote.
cite · or · abstainThe whole twin — the model, your journal, the thinking — runs inside your browser tab. Nothing is uploaded, nothing is stored on a server, no account is required. The only thing that ever leaves is an email, if you ask to be told when there's news.
no server · no biometricsIt uses your phone's own keyboard, so it understands whatever you write — English, Hinglish, Devanagari, and more — by voice or by typing. Ask “Asha kahan rehti hai?” and it answers in the same breath you asked it.
keyboard-native · voice-readyAs you type, the twin holds — it doesn't interrupt mid-thought. Pause, and it softly surfaces something you said before, right when it's useful. It learns your own typing rhythm, so the timing feels like a conversation, not a notification.
holds · reflects · never barges inTurn on a private self-view to watch yourself while you speak with your twin. Want to keep a clip? You choose — Save or Discard, every time. Nothing records without your word, and it only ever saves to your own device.

The honest catch: SelfTwin won't invent poetry you never wrote or answer trivia about the world — that's not what a twin is for. It's exactly as deep as you are with it. That's what makes it yours.
You give it your words — a journal, a thought, a memory. It keeps them safe on your phone, and hands them back when you need them: as an answer, a reflection, a nudge from your past self. It never lies, never leaks, and never pretends to be more than the words you've trusted it with. The longer you talk to it, the more it becomes you.
Open it in your browser, tell it a few true things, and watch a twin take shape. Free, private, and yours from the first sentence.
