Most of these are powered by GPT and work like ChatGPT. However, you can provide answers from the PDF you have uploaded. Here, we list seven of these tools.

AskYourPdf is a tool powered by chatgpt that allows you to upload PDFs and find useful information in minutes. Once you’ve uploaded your documents, enter a question about anything in PDF and get a to-the-point answer.

By assuming the role of a teacher, you can use AskYourPdf to understand the complex topics covered in your file using a variety of motivational techniques. Best of all, the tool is completely free to use.

In addition to PDFs, you can upload other file types including PPT, .TXT, CSV, and more. AskYourPdf supports files up to 40 MB.

You can also export your conversation as a PDF for future reference. Similarly, there is an option to share a special link that allows others to discuss your uploaded document. Rest assured, it won’t show them your chat history.

AskYourPdf is also available as a ChatGPT extension, but you must be a ChatGPT Plus user to install the plugins. Although the tool works well, you should learn to write effective questions for better results.

ChatPDF is another tool that does exactly what it says on the tin—it lets you chat with your PDF. To get started, you can upload a PDF from your device or fetch it from a URL. It also has a search feature that allows you to find PDFs from the Internet.

The tool uses GPT 3.5 and supports multiple languages. While it can’t read images in PDF, the tool can somewhat understand the table information. ChatPDF saves chat history and lets you export it. Like AskYourPdf, it has a feature to share the document via a link.

Be aware that ChatPDF responses may contain information not specified in the uploaded file. So be sure to double-check any answers.

It has both free and paid plans. The free account limits file size to 10 MB and 120 pages, number of requests to 50 per day and uploads to three documents. Upgrading to the Plus plan ($5 per month) increases these limits.

Perhaps, the best thing about Documind is searching information from multiple PDFs together.

First, the tool allows you to upload the documents either individually or in bulk. You can then visit the dashboard and start asking questions. Document scans all documents to find answers.

In addition to allowing you to extract specific information from your PDF, Docmund can generate summaries of long documents.

Another interesting use case for Docs is that you can upload a PDF to create your own chatbot and add it to your website. This way, you can use it as your customer support agent. Of course, you can also use it in your team.

However, Documind only offers 15 free credits. Beyond that, you’ll need to upgrade to three paid plans starting at $5 per month. It also provides API access.

LightPDF has dozens of tools for converting, protecting, and editing PDFs. One of them is an AI chatbot for reading PDF files. The tool not only provides quick responses to your queries, but also generates summaries, specifications and tables from the uploaded document.

Perhaps one of the most useful features is the display of the page number of the file from which the information was extracted, so you can quickly double-check it.

from SettingsYou can change the language or switch to an authentic or more creative mode. LightPDF is not limited to PDF as the tool supports Excel, Word and PPT files. To upload PDFs over 200 pages or files in a format other than PDF, you must upgrade to a paid plan.

Although LightPDF works seamlessly in the browser, it also has mobile and desktop apps.

PDF.ai has a clean yet convenient interface. It divides the tab into two columns, showing your document on one side and the chatbot on the other. Similarly, you can access all your uploaded documents and chat history from the dashboard.

In each answer, PDF.ai will cite the source (page number of the file) and take you directly to that page by clicking on it. You can adjust the display and zoom of the file to review the document yourself.

The free account only lets you upload one PDF, so it’s for testing purposes only. But if you’re willing to shell out $15 a month, PDF.ai removes all but the 50MB limit per PDF. PDF.ai also has it Chrome extension for PDF.

Although expensive, PDF.ai is a very user-friendly tool, especially if you prefer to view the document yourself rather than rely solely on AI.

Filegpt Website Screenshot

As the name suggests, FileGPT not only supports PDF, but also answers queries from various file types. These include documents, web pages, audio and videos. The paid versions also support handwritten text and unstructured PDFs.

Like Documind, FileGPT lets you query multiple files at the same time. Better yet, you can create a conversation with a collection of files and ask questions from it. This way you can keep all your files uploaded, but you can include or exclude certain files from any conversation. Therefore, it is an ideal AI tool for researchers who want to search multiple files at once.

FileGPT also displays clickable references. Clicking on these will show those extracted from the original file. You can also open the uploaded document in the sidebar, similar to how PDF.ai splits the screen.

Paid plans start at $18 per month. If you choose an advanced or premium account, you can integrate the tool into your website and provide your customers with live AI chat support. Another benefit of the upgrade is access to GPT-4 and GPT-3.5-turbo 16K, which are more powerful than GPT-3.5.

In addition to generating summaries, ClarifyPDF lets you upload files up to 10 MB and ask questions. However, it only supports English language.

Unlike the other tools listed here, ClarifyPDF lets you share your chat messages and documents with your friends via a special link. It promises to keep your chat history forever.

One disadvantage of ClarifyPDF is that it doesn’t have a free plan. And even the paid plan costs $1.99 per PDF, making it more expensive for power users.

Get useful information in a few clicks

Thanks to these tools, extracting useful information from a 100-page PDF is as easy as sending a few messages to your friends. These tools search the entire PDF and provide a relevant, concise response, just like ChatGPT’s response.

However, if you are comfortable using ChatGPT and don’t want to spend money on another tool, there are ways to allow ChatGPT to read PDFs.
