Best AI Tools to Chat
with PDF

To get a feel of ChatPDF’s capabilities, I tried it out with a mix of PDFs. I used short documents, legal contracts, picture-heavy guides. First of all, I asked it to provide answers to specific details. Next, I made the program generate overviews and clarify certain points. What impressed me most of all was how fast and accurate it was with text-heavy documents. I only needed to ask direct questions instead of flipping through multiple pages to get the needed data.

To be fair, ChatPDF was good but not perfect. It handled simple documents without issues, but when I threw it a complicated PDF with lots of images, it didn’t cope with the task properly. It would sometimes misread the text or miss key details. Still, it was way faster than manually searching. I particularly liked how quickly it answered my questions and participated in the back-and-forth conversation.

I wanted to understand whether my ideas about ChatPDF were objective. So, I asked my colleagues from FixThePhoto to test it with technical manuals. Tetiana and Kate uploaded a document with lots of diagrams. They said the program coped well with summarizing text, but it faced problems with managing diagrams and charts. Besides, there were occasional issues with the specialized terms. Still, they decided to rephrase their questions in simpler words. It really helped. Currently, you can try the tool for free, with a daily limit, and then upgrade if you need more features.

When testing Adobe Acrobat, I also used different PDFs, including detailed presentations, contracts, and reports packed with data. To see what the AI Assistant could do, I asked it various questions, had it summarize sections, and searched for key points. The program responded quickly and efficiently. Using the provided data, I was able to prepare emails, design presentations, and write documents. Most of all, I like its summarization feature. It can break down complex topics into brief and understandable summaries.

It feels that the developer really takes care of the program. For example, the latest update brought a valuable enhancement. It is possible to find answers in documents up to 200 pages long, so managing large files is much smoother.

Adobe Acrobat AI also does a great job processing tables, converting raw data into clear concepts, and generating accurate results. Plus, thanks to the improved support for German, French, Spanish, Italian, and Portuguese, I can review contracts and presentations more conveniently.

With this free PDF reader, I don’t have to spend hours, going through long documents. Besides, I’m looking forward to getting the Adobe Acrobat AI Contract feature. The Adobe team claims it will simplify legal wording, summarize details, and streamline contract reviewing. I also like a new comparison tool, which helps track changes across different agreements.

My colleague Tetiana says that Adobe Acrobat Pro DC does an excellent job with text documents. As for the price, there is a 7-day free trial. Once it expires, the subscription fee starts at $19.99 per month if you choose an annual plan. You can get Adobe Acrobat Standard and Pro based on your needs.

Some users claim AskYourPDF is the best chat with PDF AI. I wanted to figure out whether it lived up to its reputation, so I asked questions, requested summaries, and evaluated how well it handled complex tables and structured data. One thing I genuinely liked was the freedom to pick the AI model that suited my needs. GPT-4 showed amazing results with the detailed summaries and explanations. Claude, in its turn, was unmatched for structured content and contracts. Generally, the software is fast and precise. With it, document reviewing is easier.

Not everything was smooth sailing. I face a big problem when uploading large files. Some took forever to process, while others just refused to upload at all. Tetyana tested AskYourPDF with business reports and was impressed by how well it summarized contracts and decoded legalese. She also said that Mistral worked impressively fast, but its summaries weren’t always as detailed as those from GPT-4 or Claude.

I think this tool is as efficient as a specialized free PDF editor, as it enables you to add notes, highlight relevant passages, and leave comments. Another impressive feature was its ability to swiftly summarize intricate charts and tables or pinpoint key trends. This is very convenient as you don’t need to review large files manually page by page. You can start with a free plan if you don’t mind a 100-page document limit. To get the full access to advanced AI models and features, you must pay $11.99 per month (billed annually).

TextCortex is an advanced AI tool. It not only supports PDFs, DOCX, and PPTX files but also lets you upload multiple documents and chat with them at a convenient pace. I imported some photography guides, tutorials, and even a few contracts with dense legal jargon. TextCortex accurately extracted the text and responded as if it had years of experience in retouching and business negotiations. It was very impressive.

Tetiana pointed out an interesting quirk. AI does a solid job of understanding text, but if you throw in some intricate legal jargon, it may need a second to catch up. This may be a serious hindrance if you’re dealing with ultra-specialized content. On the plus side, TextCortex is a polyglot, supporting over 25 languages, including English, Spanish, French, and more.

The free version lets you generate up to 20 pieces of content daily. If you need more, there is a premium plan. It is priced at just $5.59 a month and gives you 150 generations, being perfect for those who like their AI working overtime.

When testing PDF.AI, I uploaded multiple photography-related PDFs, including equipment manuals, post-processing guides, and general photography tutorials. The tool impressed me with its rapid responses, providing insights on optimal camera settings for low-light environments and advanced editing techniques. Still, its accuracy was somewhat inconsistent. Some answers were precise and useful, while others were too vague or of little help.

This chat with documents free AI tool can summarize lengthy text pieces. Thus, I can extract relevant information in a matter of seconds. Unfortunately, the performance was inconsistent. Sometimes, PDF.AI processed documents swiftly, but there were moments when it lagged or even froze.

Tetiana liked how this artificial intelligence software could sift through long articles and pull out the essentials in no time. But when it came to complex design jargon, the responses sometimes felt more like guesses than expert insights. Moreover, if you want the premium perks, you have to pay $10 a month.

NotebookLM turned out to be a pretty handy PDF chat AI tool. It tackled all my photography-related queries with ease. Once I needed camera instructions and it was very helpful. The other time I asked for a step-by-step editing guide and received a high-quality result. Still, the most impressive feature for me is its ability to summarize long texts. Instead of digging through pages of content, I could instantly find the key points I needed.

While NotebookLM impressed me with its speed, its accuracy wasn’t always spot-on. When I asked for advanced techniques, I got surface-level answers or those without crucial details. Still, I appreciate how quickly it responds, as I can navigate documents and locate specific information promptly.

For Tanya, this tool was very helpful when she needed to summarize long documents. She used it to pull key aspects from project briefs. However, she agrees that some responses are too simplified. They may disappoint pros who need deep, detailed info. Still, its speed and user-friendly design make it a strong choice. There’s a free plan available, or you can opt for the Plus plan at $19.99 per month.

Coral AI caught my attention right away because it prided itself as the best PDF chat AI tool. In fact, it not only answers questions about a document, but actually points you to the exact pages for proof. Intrigued, I tested it with research papers, contracts, textbooks, financial reports, and academic journals. This tool can handle it all.

Curious about Coral AI’s potential, I uploaded a few photography guides focused on portrait techniques. Then, I asked some questions, namely, “What’s the best lighting setup for indoor portraits?” and “How do I tweak skin tones in post-production?” The answers were not only accurate but also perfectly concise. The bragging point of Coral AI is its ability to take complex, jargon-heavy manuals and distill them into easy-to-digest paragraphs. This is very helpful when you need to work with many lengthy documents.

Coral AI copes well with technical details, but when it comes to creativity or subjective analysis, it can be less efficient. Some responses were too general. As for pricing, there’s a free plan with two file uploads and basic chat, or you can go Pro for $14/month (billed annually) if you need more features.
