# ChatPDF vs AI Note Taker

The clearest difference is review sentiment: AI Note Taker at 100% against ChatPDF's 0%. AI Note Taker also leads on ads (none vs shown) and rating (5.0 vs 4.6). ChatPDF's advantage is ratings volume (93 vs 4) and update cadence (every 4 days vs weekly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ChatPDF sells 2 in-app purchases, starting at $14.99 per month and AI Note Taker sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
