# PDF AI vs PDF Summarizer

The clearest difference is ads: PDF AI at none against PDF Summarizer's shown. PDF Summarizer's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. PDF AI sells 2 in-app purchases, starting at $4.99 per month and PDF Summarizer sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
