As mentioned above, PDF.ai is an online PDF tool with AI features. You can use this tool to talk to your PDF and ask questions. PDF.ai finds the requested information from the PDF.

It has a significant effect when dealing with PDFs with many pages.

Furthermore, PDF.ai can summarize the PDF for you. You can leverage this to understand what the document is about. It will take you less than a fourth of the time you'd spend if you were to read the PDF.

PDF.ai is also available as a Chrome extension. If you install this, the PDF.ai chatbot will pop up every time you open a PDF from your local storage or external sources with Google Chrome. This streamlines the workflow, as you no longer have to upload the file to PDF.ai.

User Review:

Laurentiu Stefan on Product Hunt: 4/5 stars

"I'm impressed by the thought and effort that went into creating PDF.ai. It's clear that this product has the potential to revolutionize the way we interact with digital documents, and I can't wait to see where it goes from here. Congrats!"

Amir K. on Product Hunt: 1/5 stars

"I used this product, and it is fast. But it gives wrong results. That is a problem as it can mislead the user. Maybe because it uses a cheaper embedding to save cost? I think this needs to be fixed before launching it widely. Lifetime pricing is nice, but the product should work properly. It is not disclosed if this uses Open AI and which version. I wish I could rate it better, but it needs improvement before you sell it. All the best, Amir."
