Probably my favorite project to this day. Started as an MVP using Obsidian and the ChatGPT API.

This product was very interesting because it got the attention of Shaan Puri.

Turned into a product. I believe it's still the only product that can process 1M+ tokens and handle it like nothing. Cerebro is basically Notion + a second brain. It also literally means "brain" in Portuguese.
