Pitfalls to watch at work

ChatPDF

The file is stored on the service's server and stays in your account by default: keep NDA contracts and documents with personal data out, and delete files after work
The service reads scanned PDFs without a text layer poorly or refuses them
Check answers about amounts and dates on the cited page, because the model rounds

Perplexity

The links are there, but the model sometimes retells what is behind them inaccurately: open the source and find the claim word for word
For official registers (company, court, tax) the engine gives only a surface picture: check critical facts in the register itself
On the free plan, turn off AI Data Retention in settings, otherwise queries with client names may be used for training
