YouTube's built-in AI vs Signal Extractor
Ask YouTube is YouTube's own AI search. It answers questions across the whole catalogue rather than summarizing the one video in front of you.
The short answer
These two do different jobs, and knowing which you want saves you the trouble. Ask YouTube is conversational search: ask it something broad and it assembles an answer from clips, Shorts and full videos across YouTube, so it's genuinely good at finding what to watch. What it isn't is a summarizer. You can't point it at the video you already have open and get a structured read on it, and there's nothing to keep afterwards — no saved summary, no export, no clickable takeaways. It's also fenced in: signed-in US accounts, English searches only, and signed-out and supervised accounts can't use it at all. Signal Extractor does the opposite job. You have a specific video and thirty minutes you'd rather not spend: paste the link, get a one-line verdict and five to eight takeaways in about ten seconds, every timestamp clicking straight back into the video. No account, no country check, any language the video is in. Then ask it follow-up questions, push it to Notion, share it, or follow the channel and get every new upload summarized by email.

Which should you use?
Use Signal Extractor if
You already have the video and want to know what's in it, with timestamped takeaways you can check, keep, export or share.
Use Ask YouTube if
You don't know what to watch yet and want YouTube to find it — a broad question, a topic to explore, a shortlist of videos worth your evening.
Ask YouTube questions
Does YouTube have an AI summary feature?
It has Ask YouTube, a conversational search mode with an Ask button in the search bar. It answers questions using clips and videos from across YouTube. It isn't a per-video summarizer — you can't hand it one video and get a structured summary of it back.
Is Ask YouTube free?
Yes. It started as a Premium-only test and was opened up to all signed-in US viewers aged 13 and over. You do have to be signed in, and signed-out and supervised accounts are excluded.
Why can't I see the Ask button on YouTube?
Most likely you're outside the US, searching in a language other than English, signed out, or on a supervised account — all of those exclude you today. YouTube have said support for more countries, languages and devices is coming. Signal Extractor works anywhere, in any language the video is in, with no account.
How do I summarize one specific YouTube video?
Paste its link into Signal Extractor. You get a one-line verdict and five to eight timestamped takeaways in about ten seconds, and every timestamp opens the video at that second so you can check any claim. It's free and needs no account.
Can Ask YouTube summarize a video with no captions?
No. Its answers are built from content it can read, so videos without captions don't contribute. Signal Extractor falls back to processing the audio, so a video with captions disabled still gets a summary.
Can I save or export what Ask YouTube tells me?
No. It's a search result — there's nothing to keep, export or share as a document. Summaries here have a saved history, a public share link, markdown copy and a push to Notion.
Should I use Ask YouTube or a summarizer?
Use Ask YouTube when you don't know what to watch and want it to find something. Use a summarizer when you've already got a video open and want to know what's in it without spending forty minutes finding out. They're complements, not rivals.
What does Ask YouTube do better?
Discovery, comfortably. It searches the entire YouTube catalogue, blends long videos with Shorts and clips, works inside the app and on TV, and needs no extra tool. Nothing built on top of YouTube can match a feature built into it.
