Building Bersyn — AI visibility measurement for SaaS products. We scan ChatGPT, Claude, Perplexity, and Gemini
to show you what AI tells buyers about your product, then help you fix what's wrong.

Previously built ImportKit (React CSV import component). Used it as a test case for Bersyn — took it from
0.7/10 AI visibility to 3.3/10 in 10 days.

Solo founder building from Iceland.

Bersyn

I build Bersyn. It answers one question for founders: why is AI recommending my competitor instead of me. It shows what ChatGPT, Claude, Gemini and Perplexity actually say in your category, who they name, and who they quietly leave out. Building it in public, first paying customer still pending. "Type your domain at https://www.bersyn.com/. 15 seconds, no signup, see who AI recommends instead of you."
