30K: Digital Diary & Journal

30K is a personal diary that gathers your life into a book.

Keeping a classic diary is boring. 30K works differently: drop in the fragments of your day — voice, a photo, a quick thought — and the app turns them into a coherent chronicle, gradually gathering them into a book about you. A diary you don't have to work at.

HOW IT WORKS

30K doesn't just record — it hears, sees, and senses: how you speak, what's around you, and what mood you're in. From a voice note it picks up emotion, pace, pauses, and the sounds around you (the street, a café, home, the road). With photos it's the same: in a selfie it reads your state, in the frame it catches the place and the detail you shot it for. And from screenshots it sees what you lived through on your phone: what you read, watched, and scrolled, what caught you, who you messaged. It notices everything and assembles the full picture of your life — the one no one else sees.

These entries pile up — and come together into a book: not a retelling of your diary, but a story with characters, plotlines, and insights. You open it and see which new chapter has come out. Like a series, only about you.
