PrivacyDoc

You upload a document, sign in with your Google account, and ask questions about it in a chat. PrivacyDoc answers from the file's contents, so you can pull out details or get a summary without reading every page.

It is an AI PDF chatbot that works on PDFs, ebooks, txt, csv and json files.

The main selling point is privacy.

PrivacyDoc says it does not store your files, which matters if you are working with contracts, reports or other material you would rather not leave sitting on someone else's server.

Plenty of PDF chat tools skip that promise, so it is a fair reason to pick this one.

The service is free to use.

The catch is a 10MB file size limit in the free version, which rules out large scanned books or heavy reports.

Because only a free version is offered, you may find functionality is more limited than in paid document tools.

For quick questions, summaries and data extraction from everyday files, the limits are unlikely to get in the way, and the Google login keeps setup short.
