Evidence

Castmagic documents importing a file/link/feed, editing a timestamped transcript, applying recurring brand prompts and exporting text or styled clips. Transcript export formats and clip aspect ratios provide explicit output boundaries. This supports80 for recording-to-content production; transcription and drafted-content accuracy were not tested.

Limits: Source-researched AI assessment reviewed by a separate native AI worker. No hands-on product test or human verification is claimed.

Page date hints100/100

Server says last modified: Fri, 16 Oct 2026 13:53:21 GMT

A copyright year is a weak sign of upkeep. It does not prove the content is current.

Checked Oct 18, 2026.

Policy links do not verify a company's conduct. An HTML response time is not application speed. Tracker and accessibility checks miss behavior after page load. Copyright dates do not prove product upkeep.
