Claims keep their timestamp
Every takeaway is anchored to where it was said. Hedges stay hedges, and a contested point is marked contested rather than averaged into consensus.

YouTube Summarizer for Researchers
Triage a conference playlist before you commit the afternoon. Forty talks were recorded, four are relevant to you, and the cost of finding out which four shouldn't be watching all forty.
Reading is faster than watching, and always was
A conference talk runs at roughly 130 words a minute because that's the speed of speech. You read at three or four times that. The only reason to sit through a recorded talk at speaking pace is that there was no text version — which is a technical problem, not a fact of nature.
The workflow that follows is the one that falls out of fixing that: read everything at reading speed, then spend your watching budget deliberately. A YouTube video summarizer is just the mechanism — the discipline is deciding what earns the full forty minutes.

Batch the playlist
On Pro, which is on a waitlist, the whole playlist will run at once. Until then, paste the talks one at a time. You get a TL;DR for each — about a paragraph, enough to tell relevance from adjacency.

Shortlist on the takeaways
For anything that survives the TL;DR, read the key takeaways. This is where most of the false positives die: talks whose title promised your problem and whose content addressed a neighbouring one.

Watch the shortlist properly
Four talks, watched attentively, with the chapter map open so you know what's coming. This is the part that was always worth your time — it just no longer costs you the other thirty-six.

Cite to the second
When you quote a talk, the timestamp goes in the citation. Anyone checking your work lands on the exact moment rather than being told to watch a forty-minute video and trust you.
What matters most
Built for work that gets checked
Batch a whole playlist
Queue a conference channel or a reading-group playlist in one go instead of feeding it links one at a time. Coming with Pro.
Cross-language literature
The relevant talk isn't always in English. A talk in any language with captions is summarized in that language, free, with terms of art kept as spoken; translating the summary into your own language is coming with Pro.
Where you still have to be careful
A summary reflects what was said, not whether it holds up. Auto-generated captions also mis-hear specialist vocabulary and unfamiliar names more than they mis-hear ordinary speech, which is exactly the vocabulary you care about. Before anything goes in a citation, open the timestamp and check the wording against the source.
