About

Second Brain is built by one person — me, Gökhan Çelikkaya. No investors, no growth team.

It exists because I kept texting myself things — parking spots, medicine doses the vet mentioned, the name of a good electrician — and then losing them in my own chat history. Notes apps wanted folders and titles; what I wanted was to ask.

So the app is a chat: you drop thoughts in, and later you ask for them back. That’s the whole idea, and everything in it serves that.

Questions, problems, ideas — write me anytime.
