Both score well (8.0 vs 8.2) but answer different kinds of questions.
| ChatPDF | Perplexity | |
|---|---|---|
| Overall | 8.0/10 | 8.2/10 |
| Price | Freemium | Free / $20/mo |
| Scope | One uploaded document | The open web |
Verdict: ChatPDF when the question is confined to a document you already have — “what does this contract say about termination.” Perplexity when the question requires searching the live web with citations. Anyone handling confidential material on ChatPDF should verify its data-handling terms first.
