Private beta — iOS & Android

Your head is not a filing cabinet.

Brain² catches every thought, task, and link the moment you say it — by voice or by text — sorts it, and comes back later asking whether you actually did it.

"Renew the passport before the trip, and remind me to send Jonas the deck tonight."

01 — Capture

Say it. Type it. It's already logged.

Talk to Brain² like an assistant standing next to you. Every voice note gets transcribed, every scrap of text gets a home — a thought, a task, a link, something to watch, something to buy.

02 — Sort

Nothing sits in a pile.

Every capture lands in one inbox and gets tagged as it arrives — work or personal, project or one-off — so a 2am idea and a Tuesday grocery run never end up in the same undifferentiated mess.

03 — Follow through

It checks back. On purpose.

Ask for the daily brief and get the morning in one message. Run the weekly review and see what actually moved. Brain² doesn't wait for you to remember it exists — it notifies you when it has something worth saying, and gives location-aware answers when that helps.

"You've opened four different projects today. Which one is actually the flagship?"

— the kind of thing Brain² says back to you

04 — Connect

It already knows where you work.

Link Gmail, Google Calendar, Google Drive, Outlook, or Canvas once, and Brain² can read the context it needs instead of asking you to paste it in every time.
