Turn agent work intoclient-ready walkthroughs
A narrated walkthrough of everything your agents ship. No human hits record.
How it works
A real demo, every time your agent ships
Spool drives the actual app, records it, narrates it, and publishes a single link.
Real recordings, not slideshows
Playwright drives the live app. Continuous video with a smooth cursor, auto-zoom on clicks, and word-synced captions, never a deck of stitched screenshots.
Narrated like the engineer who built it
An AI voice walks through the change the way the person who shipped it would brief a client. Calm, specific, and client-ready by default.
Built for your pipeline
spool build then spool publish from any CI job. Every merged change can leave with its own walkthrough, hands-off.
One link for humans and agents
Humans get a watch page. Agents get a machine-readable spool.json receipt, with chapters, transcript, and console telemetry travelling alongside the video.
