Your thoughts deserve better than a folder. Cerebro is an AI-powered thought journal that remembers so you don't have to. Open the app, write what's on your mind, and close it. That's it. Cerebro handles the rest: organizing your thoughts, extracting action items, and bringing forgotten ideas back at the right moment. How it works: - Open the app to a blank editor. Write freely in markdown. - AI silently processes every entry. No chatbot, no conversation. - Todos are extracted automatically from your natural writing. - A living memory document evolves with your thinking over time. - Push notifications resurface forgotten thoughts with context like "You mentioned wanting to learn Rust a week ago. Any progress?" Semantic search that actually works. Type "that creative project idea" and find an entry about building a camera app, even if those exact words never appeared. Cerebro understands meaning, not just keywords. Built for the forgetful. If you've tried journaling apps and abandoned them because organizing felt like a chore, Cerebro is different. There are no folders, no tags, no categories. You write. The AI organizes. Thoughts come back when they matter. Perfect for ADHD minds. Cerebro was built by someone who forgets things. The entire design removes friction: no onboarding, no setup, no maintenance. Just a blinking cursor ready for your next thought. What Cerebro is not: - Not a notes app. You don't organize anything. - Not a chatbot. The AI works silently behind the scenes. - Not a productivity system. It's a thought persistence layer.
