Start with a 7-day free trial — full Pro access, no credit card required
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.
Starter gives you the core tool plus basic AI features (Speed Mode 5/mo, Video Chat 3 msg/session). Plus adds Socratic Questions, Ask Your Library, and knowledge graph syncing with higher limits. Pro unlocks everything unlimited — for just $3/mo more than Plus.
After your 7-day trial with full Pro access, you'll need to choose a plan to continue. All your videos, notes, and data are preserved — you just pick the tier that fits your learning style.
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.
