MensorAI started as a YouTube note-taking tool for learners. Now it saves articles, passages and YouTube moments as you go, and when you sit down to write, you ask across all of them. Every answer links back to the passage it came from.
Sound familiar? Here’s what usually gets in the way.
Here’s what it does for this kind of work today.
Save the YouTube moment you’re at, whole articles, passages you select and your own notes without paying. The web app also takes YouTube links.
7-day free trial of Pro features with a limited AI allowance. No credit card required. Asking across your library and finding videos on YouTube need that trial or a paid plan.
Starter is $9, Plus $19 and Pro $22 a month. The only difference is how many AI requests you get per day: 10, 50 or 100.
When the trial ends, everything you saved stays in your library and you can keep saving for free. You only pay if you want to keep asking.
