MensorAI is for researching what you’ll write. The browser extension saves the article you’re reading, a passage you select or the YouTube moment you’re at, with your own note kept separate. When you write, you ask across everything you saved, and every claim links to the passage it came from.
No. If you want to remember what you read and watch, Recall, Readwise Reader or Anki are better picks. MensorAI is for finding and quoting your sources when you write.
You can save any public video. Ask needs text, so it relies on the captions and your own note. Videos without captions have little to search beyond your note.
Saving 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.
