Capture at the speed of thought

A voice note on your walk, a one-liner between meetings. No app to open, no form to fill — it's the messenger you already use, and every message is saved and transcribed automatically.

A memory that connects the dots

That idea you had three weeks ago and the problem you're chewing on today? Rambling notices they're related and shows you — so recurring themes stop slipping away.

You've circled back to this three times now. What would change if you actually tried it?

Brainstorming modes on demand

Explore an idea with open questions, expand it in new directions, or have it challenged. When you're done, you get a wrap-up with key points, open questions, and possible next actions.

Your thought palace compounds over time

Every thought you capture makes the next connection more likely. Weekly recaps land right in your WhatsApp, and one tap takes you to your dashboard — no password, no login screen.
