VidQuest AI

Paste a YouTube lecture link, ask what the speaker said about a specific topic, and get an answer without sitting through the whole video.

VidQuest AI is an AI video search and question-answering tool for YouTube that also finds where keywords or phrases come up in a video.

The free plan covers keyword searches for 3 words or phrases a day, plus questions on videos up to 15 minutes, capped at 5 questions daily.

Paid options run from short passes to monthly plans.

The monthly Premium plan raises the limit to 30-minute videos and 50 questions a day.

Pro and VIP handle videos up to an hour, with 100 or 250 questions a day, and VIP allows up to 10 longer videos daily.

Pro and VIP include full keyword finder access, and Keyword Finder is also sold as a one-time purchase with no daily search limit.

Chat history from earlier videos is kept on paid tiers.

The free limits are tight, so heavy users will need a plan.
