Whether it's for study or work, scrolling through lengthy PDF files to find any specific information is the most tedious thing ever.However, you can make things easier by using artificial intelligence tools that answer PDF questions.


Most of these tools are powered by GPT and work similarly to ChatGPT.However, they can provide answers from PDFs you upload.Here, we list the top seven of these tools.

1. AskYourPdf


AskYourPdf is a tool powered by ChatGPT that allows you to upload a PDF and get relevant information within minutes.Once you've uploaded the file, type in a question about anything in the PDF and get a to-the-point answer.

By using different prompting techniques, such as giving it the role of teacher, you can use AskYourPdf to understand complex topics discussed in the document.Best of all, this tool is completely free to use.

In addition to PDF, you can also upload other file types, including PPT, .TXT, CSV, etc. AskYourPdf supports files up to 40MB.

You can also export your chat history as a PDF for future reference.Likewise, there is an option to share a unique link to allow others to chat with your uploaded file.Don't worry, 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 plugin.While this tool is great to use, you have to learn to write effective prompts for best results.

2. chatPDF


ChatPDF is another tool that does exactly what it says - lets you chat with your PDF files.To get started, you can upload a PDF from your device, or fetch it from a URL.It also has a search function that lets you find PDFs from the internet.

The tool uses GPT 3.5 and supports multiple languages.While it cannot read images in PDFs, the tool can understand tabular data to a certain extent. ChatPDF can save chat history and let you export it.Just like AskYourPdf, it has a feature to share files via a link.

Note that ChatPDF's replies may also contain information not mentioned in the uploaded file.Therefore, be sure to double-check any answers.


3. Document


Perhaps, the best thing about Documind is that you can search information from multiple PDFs together.

First, the tool lets you upload files, either individually or in batches.Then, you can visit the dashboard and start asking questions. Documind will scan all files for answers.

In addition to letting you find specific information from your PDFs, Documind can also generate summaries of lengthy documents.

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

However, Documind only offers 15 free credits.Beyond that, you'll have to upgrade to any of three paid plans, with prices starting at $5 per month.It also provides API access.

4. LightPDF


LightPDF has dozens of tools for converting, protecting and editing PDFs.One of them is an AI chatbot for reading PDF files.Not only does the tool answer your questions quickly, it also generates summaries, outlines, and tables from uploaded files.

Perhaps one of the most handy features is that it displays the page number of the document from which the information was extracted, so you can quickly double check.

In the settings, you can change the language or switch to a more precise or creative mode. LightPDF is not limited to PDF only, as the tool also supports Excel, Word and PPT files.If you want to upload PDF files longer than 200 pages or files in formats other than PDF, you must upgrade to a paid plan.

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

5. pdf.ai


PDF.ai has a fairly clean and convenient interface.It splits tabs into two columns, showing your files on one side and chatbots on the other.Likewise, from the dashboard, you can access all uploaded files and your chat history.

For each answer, PDF.ai mentions the source (the page number of the document), and clicking on it takes you directly to that specific page.You can adjust the display and zoom of the document to review the document yourself.

The free account only allows you to upload one PDF, so it's just for testing purposes.But if you're willing to shell out $15 a month, PDF.ai removes all limits except 50MB per PDF.

Although costly, PDF.ai is a great, user-friendly tool, especially if you prefer to view files yourself rather than relying entirely on AI.

6. FileGPT


As the name suggests, FileGPT can answer questions from different kinds of files, not just PDFs.These files include documents, web pages, audio, and even video.The paid version also supports handwritten text and unstructured PDF files.

Much like Documind, FileGPT lets you ask questions from several files at once.Even better, you can create a chat with a file set and ask questions from it.This way, you can keep all uploaded files, but include or exclude specific files in any chat.Therefore, it is an ideal AI tool for researchers who want to search through multiple files at the same time.

FileGPT also displays clickable references.Clicking on these displays an excerpt from the original document.You can also open uploaded files in the sidebar, similar to how PDF.ai splits the screen.

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

7. Clarify PDF


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

Unlike the other tools listed here, ClarifyPDF allows you to share your chat messages as well as files with friends via a unique link.It promises to keep your chat history forever.

One of the downsides 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.

Information is just a few clicks away

Thanks to these tools, finding relevant 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 answer, just like a ChatGPT response.This will greatly improve your work efficiency.
