About

Madless

Madless is the place you keep your own mind. Capture what you let in — a note, a voice memo, a photo, a link — the moment it matters, and it's kept: laid out and connected, so you can find it again and see what you think. A map, not a feed. No infinite scroll, nothing deciding what comes next. Only what you chose to keep. WHAT YOU CAN DO • Capture anything — type a thought, record a voice memo, take a photo, or save a link. Share into Madless from any other app, too. • Search everything you've kept — by meaning, not just exact words. • See the shape of your thinking — your connections, themes, and the threads still left loose. WHAT MADLESS WON'T DO No ads. No feed. No selling your data. No training AI on what you keep. Keep your own mind.
