Eightify
A narrow tool that does one job well: decide whether an hour-long video is worth an hour before you spend it. The timestamped key points are the real feature, because they let you jump straight to the section you actually needed. The catch is that it is subscription-only for a job several free extensions and general assistants now also do.
Pros
- Key points come with clickable timestamps, so the summary doubles as navigation
- Handles very long recordings rather than capping at a few minutes
- Output available in roughly 40 languages, including summarising an English video into another language
- Works inline on the YouTube page instead of asking you to paste URLs elsewhere
Cons
- No permanent free tier — after the trial it is pay or nothing
- Summary quality is bounded by YouTube's auto-captions, which are poor on accented or technical speech
- The vendor blocks automated access to its own site, so pricing and terms are hard to verify independently
