How secure is ClarifyPDF?

Secure enough for non-sensitive content. You should not upload any private or sensitive material. Read our Privacy Policy.

How is this different to ChatGPT?

ChatGPT only provide answers from public information on the internet, and only for content before 2021. ClarifyPDF answers questions based on the content of the PDF you upload.

Does this use GPT-3.5?

Yes. GPT-3.5-turbo-16k, to be exact. We will have GPT-4 access ready when we launch our credit-based usage.

Can I upload multiple documents?

Bulk upload will be available soon, including integration with Google Drive, Dropbox and Notion. Get updated with new features.

What languages do you support?

All languages! It's best with paragraph content, not bad at tabular data, and doesn't yet understand code.

Can I get a refund?

Yes, we have a no-questions 100% refund policy.

Get informed. Quickly, easily and naturally.

Reading is great. But for most of the time, we just want to get straight to the information. By asking questions.
