Verdict

The call

The clearest difference is monetization model: ChatPDF at free with in-app purchases against Slides AI's subscription. ChatPDF also leads on rating (4.6 vs 4.3) and ratings volume (95 vs 16). Slides AI's advantage is ads (none vs shown). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
