Try Speed Mode free on your first video
All your videos, notes, and insights stay with you forever. You just lose access to AI features like Speed Mode, Video Chat, and semantic search. You can still view and edit everything you've created.
Currently MensorAI is optimized for YouTube. We're focused on doing one thing exceptionally well. Support for other platforms may come in the future based on community demand.
Yes. Your notes are private by default. Only lessons you explicitly choose to publish become visible to the community. We never share or sell your data.
Free users get 3 AI requests per day. Premium unlocks 100 requests/day plus Speed Mode (briefing, quiz, evaluation, notes in one flow), Video Chat, and semantic search across your entire library.
I spent years watching educational content, feeling productive, but retaining almost nothing a week later. The gap between consumption and understanding was frustrating.
I built MensorAI to close that gap. It is not designed to optimize your engagement metrics. It is designed to optimize your retention.
This is a tool for the intentional learner. The person who watches to understand, not just to kill time.
Turn your watch history into real progress today.
