ChatPDF: Upload a PDF and ask questions with page references, with no sign-up for the first files.

Mem: Notes that AI links together on its own and that you can search with a question.

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

Notes are stored in the service's cloud: keep passwords and employee personal data out
An answer from your notes also pulls in outdated entries: look at the date of the note it cites
Test the note export before moving your whole base there, so you have a way back
