Watching a lecture twice isn't studying. Testing yourself on it is.
YouTube is full of high-quality lectures from universities, professors, and subject experts. But watching a video — even a great one — does almost nothing for long-term retention if you don't test yourself on the content afterward.
Learnlo turns passive watching into active learning. Paste the YouTube URL, get your study pack, take the exam, and find out which parts of the lecture actually stuck.

Question
According to the lecture, why does the action potential have a refractory period, and what are the two types?
Student Answer
The refractory period prevents the action potential from going backwards. The absolute refractory period is when no new action potential can fire at all.
AI Grading Feedback
6 / 10Good start — you correctly identified the directional function and the absolute refractory period. To complete the answer: (1) the relative refractory period allows a new action potential only with a stronger-than-normal stimulus; (2) both periods are caused by the inactivation state of voltage-gated sodium channels, which the lecture specifically emphasized.
Frequently Asked Questions
What YouTube videos work with Learnlo?
Educational lectures, university course videos, subject tutorials, and documentary-style explanations work best. The video needs either auto-generated captions or clear audio for transcription. Music videos, gaming content, and non-educational videos won't produce useful study packs.
Does the video need to have captions already?
Captions help but are not required. Learnlo uses audio transcription when captions aren't available. Videos with clear English audio typically produce accurate transcriptions.
How long can the YouTube video be?
Learnlo supports videos up to about 2–3 hours. Longer videos may be trimmed to the most content-dense sections within the plan's processing limit.
Can I use lecture recordings posted publicly on YouTube?
Yes. University lecture recordings, Khan Academy videos, MIT OpenCourseWare, and similar public educational content all work well.
Are the exam questions from the video or from general knowledge?
From the video. Learnlo generates questions based on the specific content in the lecture — what the professor said, the examples they used, and the concepts they emphasized. Not generic questions about the subject.
Can I get flashcards from a YouTube video too?
Yes. Every study pack includes flashcards, notes, quiz, practice exam, podcast, and mind map — all generated from the YouTube lecture content.
Do I need to sign up?
No. Guest users can paste a YouTube URL and generate a full pack including the practice exam without creating an account.
