Under every decent video sits a focus group that paid for itself: hundreds of comments where your audience tells you, unprompted, what confused them, what they want next, and which thirty seconds they'd watch a full video about. Creators know this in theory. In practice, comment sections get skimmed for praise and trolls, and the request layer — "please make one about X", "you lost me at the part where...", "does this work for Y?" — scrolls past unmined.

Multiply by your whole channel, then by your competitors' channels (whose audiences are your audience), and there's a content calendar sitting in plain sight: ideas pre-validated by the exact people who'd watch them, expressed in the exact words they'd search with.

run_youtube_tool's comment-summarizer reads the whole section so you don't: recurring questions, requests and confusion points, aggregated and ranked by frequency instead of by recency and rage. comment-sentiment adds the temperature — which themes come with enthusiasm (make that video) versus frustration (fix that gap).

Run it across your recent uploads and the mine produces your backlog; run it across your competitors' biggest videos and it produces theirs — the requests their audience made that they haven't fulfilled. Both passes work on any public video from its URL. The output isn't inspiration; it's demand, counted, in the audience's own phrasing — which doubles as your title draft.
