Gistly
It does one job well: the summary appears next to the player rather than in another tab, and the timestamps actually move the video. The problem is commercial opacity — you cannot see what the paid tier costs without entering a checkout flow, which is a poor way to ask for a card.
Pros
- Summary widget renders inside the YouTube page, with no copy-pasting of URLs
- Timestamped sections link back into the video at the right moment
- Also generates full transcripts and blog-post drafts from the same video
- Handles more than 40 languages
Cons
- No published price list, and the only checkout link on the site sells a different product
- Publisher is a bare name with no address, country or company registration
- The extension has not been updated since August 2024 (version 0.0.4)
- Entirely dependent on YouTube transcripts, so videos without them are out of scope
