Diffcast
Turn your changelog into a 30-second narrated demo clip — automatically, on every release.
The pitch
The problem
Teams ship features nobody notices. Changelogs go unread; recording demo videos by hand takes an afternoon nobody has.
The idea
Connect your repo. On release, Diffcast reads the changelog and diff, drives a headless browser through the new feature, and renders a short narrated clip ready for Slack, X, or your docs.
Why now
Browser agents can finally follow "click the new button" instructions reliably, and TTS stopped sounding like a robot reading a phone book.
