# PDF Summarizer vs PDF AI

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 16). On price and in-app purchases there is nothing between them.

Both are free to download. PDF Summarizer sells 2 in-app purchases, starting at $6.99 per month and PDF AI sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
