# Professor Index vs AI Note Taker

The clearest difference is rating: Professor Index at 4.5 against AI Note Taker's 3.8. Professor Index also leads on in-app purchases (none vs 7) and ads (none vs shown). AI Note Taker's advantage is update cadence (weekly vs monthly) and review sentiment (100% vs 88%). On price and device support there is nothing between them.

Both are free to download. AI Note Taker sells 7 in-app purchases, starting at $7.99 per 7 days. Professor Index asks for nothing beyond the download.

Professor Index holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Professor Index has 59 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 88% of Professor Index's written reviews are positive against 100% of AI Note Taker's, so the app with the better star average is not the one people write more warmly about.

Professor Index ships an update monthly, AI Note Taker weekly. The most recent releases landed on September 20, 2026 and September 25, 2026 respectively.
