Turn release notes into a demo video — automatically.
Ship a feature. Type /devcast. Get a shareable talking-head demo with narration, app walkthrough, subtitles, and a hosted link — without recording.
- Stay in flow (no recording or editing)
- Story-driven narration + clean walkthrough
- Export for internal updates now, external soon
Likeness/voice optional, permission-based, reviewable before export.
Sound familiar?
You ship fast. Communicating what you shipped shouldn't slow you down.
"We shipped 40 features this quarter and nobody outside eng even noticed."
"Our changelogs are a graveyard. Long, unread, forgotten."
"I spent more time recording the demo than building the feature."
