A note from the builder

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. I hope it serves you well.
