Rewatching a 90-minute lecture to find one concept is not a study strategy.
Video lectures are a dense way to deliver information, but they are a poor format for review. There is no way to skip to what you need, skim the key points, or quiz yourself on the concepts without sitting through the whole thing again. Passive re-watching feels like studying, but it produces weak memory retention compared to active recall.
Learnlo extracts the content from any YouTube video and converts it into a full interactive study pack. Instead of rewatching, you get a structured summary, flashcards for active recall, a multiple-choice quiz, and an AI-graded practice exam — all from a single URL paste.

Frequently Asked Questions
Is the YouTube summarizer really free?
Yes. Guest users can summarize one YouTube video and get the full study pack without creating an account. Free accounts get 3 packs per month at no cost.
What length of YouTube videos does it work with?
Up to 30 minutes on the free plan. Plus extends this to 90 minutes. Videos must have captions or audio that Learnlo can process.
Does it need closed captions to work?
Learnlo uses YouTube's captions when available and falls back to audio transcription. Most lecture videos work well. Music-only or heavily visual videos without speech will not produce usable study material.
Do I get more than just a summary?
Yes. You get a structured summary, key ideas, study notes, flashcards, a multiple-choice quiz, an AI-graded practice exam, and a mind map — all from one URL paste.
Can I use this for university lecture recordings?
Yes. Any YouTube video with substantive spoken content works — lecture recordings, educational series, tutorial videos, and documentary-style content all produce good study packs.
How is this different from YouTube's built-in summary?
YouTube's summary gives a text overview. Learnlo converts the video into interactive study material: active recall flashcards, a quiz, an AI-graded exam, and a knowledge-gap map — built for studying, not just reading.
When would I need to upgrade?
For videos longer than 30 minutes, more than 3 packs per month, packs that last more than 7 days, or to access podcast and slideshow audio downloads and content editing. Plus is $9/month.
