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.

Saving sources is free. Asking and finding videos on YouTube need an active trial or a paid plan. You get a 7-day free trial of Pro features with a limited AI allowance. No credit card required. After that, plans are $9, $19 or $22 a month, and they differ only in how many AI requests you get per day.
