Which YouTube tools actually read the whole channel?
Most tools read one video at a time. Creator tools read a whole channel, but only its numbers. Of the eleven tools below, exactly one other reads YouTube comments at all — and only for the single video you are watching. Taffy indexes every video and every comment on a channel, then cites the exact episode and timestamp.
Capabilities and pricing verified July 2026. Where a vendor blocks automated checks, the price is marked corroborated and the source named.

Common questions
Only Taffy. Of the tools compared here, Eightify is the only other one that reads comments at all, and only for the single video you are watching. vidIQ and TubeBuddy touch comments for moderation and filtering, not meaning. NotebookLM, Gemini, ChatGPT, Glasp, NoteGPT and Recall do not read comments.
It depends on your source type. NotebookLM takes one captioned video per source and reads only the transcript. If you need a whole YouTube channel indexed, including its comments, with answers cited to the exact episode and timestamp, Taffy is the only tool that does it. For single-video summaries, Glasp and NoteGPT are strong.
No. As of July 2026, summarize.tech and www.summarize.tech both return HTTP 503, "Deployment paused by owner". The service is not functional. Many alternatives lists still recommend it.
No, and it is not trying to. vidIQ and TubeBuddy report a channel's numbers: views, tags, thumbnails and comment moderation. Taffy answers questions about the words in your videos and the words in your comments. Most Creator Club members run both.
Read every video and every comment on your channel.
Creator Club indexes your channel and three competitors, and cites the episode and timestamp for every answer.
