Unsent

An app that learns to understand you,
through your own diary.

Your diary is kept in Unsent — not in the AI you talk to.

  • Free to start — no card needed
  • We never post anything on your behalf

Write your diary from the AI you already use

Talk to Muse, Claude, or ChatGPT as you always do — and save it as a diary entry, right from the conversation. Everything goes into one diary.

The more you write, the better it understands you

As your entries grow, your AI can read the shifts and patterns in how you feel — and answer in words that fit you.

Your diary stays in Unsent

Your entries are stored in Unsent, and you can read, download, or delete them anytime. When you ask an AI about your diary, only the entries it needs are shared with that conversation, under that AI's own privacy policy.

The more you keep it up, the more the view changes

Keep writing, and you get to know yourself. Know yourself, and your days change.

  • Just talk, and your AI turns it into writing. Nothing to prepare, so what never stuck starts to stick
  • The more you write, the more your AI can read the shifts and patterns in how you feel — and you start to understand how to handle them
  • Your days grow lighter, one entry at a time. The same day starts to look a little different

Because you keep going, you get to know yourself. Because you know yourself, living gets a little easier.

Also

  • Keep it close on your home screen

    Add it to your phone's home screen to open it as an app — ready the moment you want to read back.

  • Your past self, arriving unannounced

    Now and then, a past entry quietly returns by email — a reminder that the unsteadiness isn't only today's.

  • Download everything, anytime

    Your words are yours. Export your whole diary whenever you like, and delete your account in one step.

  • Never posted, never shared

    Unsent doesn't post anything on your behalf, and nobody sees your entries unless you choose to share them.
