By: Bogdan Rancea

- January 13, 2025

I finally found a PDF with all the info I needed for my project. But as soon as I opened it I realized it was 300 pages long.

There was no way I could read the whole thing to get what I needed. If only there was a way to summarize the text so I could find the data without all the bother. That’s where AI PDF readers come in.

ChatPDF is one of those tools—an AI PDF reader that reads documents and answers questions to help you find what you need.

But you don’t like ChatPDF? Good news! There are plenty of other options to choose from. Let me show you 9 great ones to help you get the most out of your PDFs.

What is ChatPDF?

ChatPDF is an AI tool to interact with PDF documents. You can upload PDF files and chat with them—ask questions, extract data, get summaries. Good for long or complicated documents when you just need specific info.

ChatPDF Pros:

• Simple page and chat interface.
• Automatically detects language of your PDF and gives multilingual answers.
• Humanized responses feels like talking to a person.

• Answers get less accurate after 10th page of the document.
• No PDF conversion or editing feature.

Why Look for ChatPDF Alternatives?

ChatPDF is great but not for everyone. Maybe you need more features, better integration with your workflow or a simpler interface.

Or maybe the pricing doesn’t fit what you’re looking for. Whatever the reason there are other tools that might suit you better.
