Noiz
The timestamps are what make it worth using: every extracted point links back to the moment in the video, so the summary is a navigation aid rather than a replacement you have to trust blindly. Twelve-hour support and 41 output languages cover the awkward cases most summarisers punt on. It is one narrow job, done without ceremony.
Pros
- Timestamped key ideas that link back to the exact moment in the video
- Handles videos up to twelve hours, including podcasts
- Output in 41 languages independent of the source language
- Chrome extension summarises in place without leaving the video page
- Same product available as iOS and Android apps under the Eightify name
Cons
- No API and no bulk processing
- The vendor's pricing page returns a server error, so prices are second-hand
- Two brand names for one product (Noiz and Eightify) makes support and billing confusing
- Free allowance is small and the site does not state its exact limit
