Modern social platforms prioritize reach over resonance. 150.fyi is a technical intervention—an encrypted layer built for the people you actually trust.
150.fyi runs via an encrypted browser extension. Once active, every URL on the internet becomes a canvas for discussion. It’s a hidden layer that only your circle can see, existing "above" the website content.
Your inner circle is hard-capped at 150 people. This isn't a bug; it's a feature. By restricting your network to the "Dunbar Number," you ensure that every comment you see comes from a person you know and trust.
View a live feed of what your crew is interested in from across the web. Discover new ideas and engage in real-time conversations on any page, from niche research papers to products, services and breaking news.
Forget anonymous reviews and toxic comment sections. 150.fyi replaces the algorithmic noise with real, direct insights from your peers. It’s a tool for collaboration, note-taking, and high-signal sharing.
