The brief that replaces
your infinite tab switching

Most developers spend 20 minutes every morning across Twitter, HN, and newsletters just figuring out what is worth reading. Cobun AI compresses that into 90 seconds.

The daily brief runs every morning across every category — an AI-generated summary of the highest-signal items from the last 24 hours.

Not a curated opinion. A structured summary of what the community actually engaged with, ranked by real signals.
