Top 7 AI tools that can read PDFs
Alright, let’s jump into the list. Here are some of the best AI tools out there that give you powerful ways to interact with your PDF documents, helping you get the information you need faster and more efficiently.
1. eesel AI
eesel AI isn’t just your average PDF reader. It’s actually a full AI platform built to automate and improve customer support by using knowledge from all your documents. Yes, that includes PDFs, but it also pulls from past support tickets, help centers, internal wikis like Confluence, documents in Google Drive, and over 100 other places. It uses PDFs as a really important knowledge source to train smart AI Agents and Assistants that can actually do things, not just answer questions.
This platform takes the content from your PDFs (along with all those other sources) and uses it to power AI Agents for automating those first-level support questions and sorting tickets smartly. It also helps fuel the AI Assistant (think of it like a Copilot) to draft replies and grab information for your human agents right within their workflow, all based on the knowledge it’s been trained on, including everything in your PDF content. Plus, because you can customize the prompts and actions, the AI can do more than just read the PDF; it can act on the information it finds. For example, it could use data from a PDF policy document to process a refund by connecting through an API.
Here’s why people like eesel AI:
- It uses PDF content for practical, real-world tasks like automating support conversations.
- It trains on lots of sources at once, giving it much richer context than just one PDF.

- The pay-per-interaction pricing is clear and can be more cost-effective, especially compared to paying for every single agent.

Choosing the right AI tool that can read PDFs for your needs
The best tool depends on what you actually need to do with your PDFs. Are you looking to chat with one file for research or studying? Or do you want to take information from multiple documents and use it to automate workflows, like customer support or internal help?
Here are a few things to think about:
- Use case clarity: If your goal is simple Q&A or summaries from a single PDF, tools like ChatPDF, AskYourPDF, or PDFGPT IO are solid picks. If you also need editing features, UPDF or Foxit could be a better fit. For teams needing full-scale automation powered by PDFs and other content, eesel AI is built exactly for that.
- Where your knowledge lives: Is your content only in PDFs, or scattered across help centers, past tickets, and cloud folders? eesel AI connects to all of these, training on them at once for more accurate and useful answers.
- Integration support: Need it to work with Zendesk, Intercom, or your CRM? Make sure the tool connects smoothly. eesel AI supports deep integrations and lets you set up custom API actions to move beyond basic responses.
- Pricing transparency: Look for a pricing model that fits your usage. Page-based or agent-based pricing can get expensive fast. Models like eesel AI, which charge based on actual usage, are often easier to manage.
- Accuracy and testing tools: Can you test how it performs before rolling it out? This is key if you’re using it in support or customer-facing roles. eesel AI lets you preview results and simulate live conversations.
- Real action, not just answers: Some tools just give you answers. Others, like eesel AI, go further by performing tasks such as tagging, routing, or pulling data, which is crucial for business use.
Choosing the right tool means making sure its abilities match your specific workflow needs and thinking about how it will work as your data and team grow.
The future of working with PDFs and AI
The way AI is learning to “read” PDFs shows a clear trend: we’re moving past just asking questions and getting answers towards AI that is integrated and can actually take action. Documents aren’t just static files anymore; they’re becoming dynamic sources of knowledge that AI can tap into to automate tasks, help you make decisions, and make complex processes smoother, especially in areas like customer support and managing internal knowledge. The ability to pull out, understand, and act on information from all sorts of documents is getting incredibly powerful.
