How reliable is AI summarization?
For getting the shape of a document, it is reliable. The weak spots are numbers, conditional clauses, and negation — "declined" becoming "unchanged", or a hedged conclusion turning into a flat claim. Verify any figure or condition you plan to act on against the original.
Can it summarize YouTube videos or meeting recordings?
Yes, but quality is decided by the transcript, not the summarizer. If auto-captions are inaccurate or speakers are not separated, the summary degrades with them. For meetings, check that the tool supports speaker diarization before relying on it.
