AI-Powered Second Brain

Think freely.
Never forget.

The app that remembers so you don't have to. Write your thoughts, and let AI organize, connect, and resurface them at the right time.

WriteTodosMemory

Just had a great idea for the onboarding flow —

what if we skip it entirely and let the blank

editor be the onboarding?

Need to follow up with Maya about the Q2 design

review. Also remind me to cancel that subscription

before Friday.

Extracted 2 todos: "Follow up with Maya about Q2 design review" and "Cancel subscription before Friday". Connected to 3 previous entries about onboarding.

Your brain, but better

Write first, organize never. Cerebro does the thinking about your thinking.

✍️

Blank canvas

No folders, no tags, no templates. Just a blank markdown editor. Write whatever comes to mind.

🧠

AI memory

Cerebro builds an evolving document about you — your patterns, your projects, your priorities.

Auto todos

Action items are extracted automatically with urgency levels. No manual tagging required.

🔔

Smart resurfacing

Get nudged about the right thought at the right time. Like a smart friend who never forgets.

🔍

Semantic search

Find thoughts by meaning, not keywords. Vector-powered search that understands what you meant.

🌙

Light & dark

Beautiful adaptive themes that feel right on your device. Electric lime in the dark, warm moss in the light.

How it works

Three steps. Zero configuration.

01

Write anything

Open the app and start typing. Markdown supported. No categories, no friction. Just your raw thoughts.

02

AI does the rest

Cerebro silently extracts todos, connects related thoughts, and builds a memory of your patterns and priorities.

03

Get nudged

When something becomes relevant — a deadline, a connected idea, a forgotten follow-up — Cerebro brings it back to you.

Ready to stop forgetting?

Your thoughts deserve a brain that never drops the ball.
