Some limitations of the most welcoming AI PDF readers right now:

Part 2. 3 Best Websites to Upload and Chat with PDF

Here you can visit 3 websites that offer free services to summarize PDF and prepare you answers for any relevant questions based on the content of your uploaded PDF documents. 

#1. Chatwithpdf

The first option here is an all-language-supported AI PDF reader. This website allows anyone to upload 2 PDF documents every day, with unlimited questions you can put forward until you fully understand all the key points mentioned in your PDF document.

Verdict:

This PDF AI Reader is so far the most powerful tool we can find on the Internet. A big issue though is that it cannot understand images, which is a pity since essays and business reports greatly depend on data analysis. Users cannot get figures and numbers from authoritative PDF documents. That’s the only downside of this perfect PDF chatbot. 

#2. Monica ChatPDF

This AI PDF reader is a lifesaver for those who don’t know how to ask AI questions. You can start with a very general question such as ‘What’s the topic of this PDF’ and then after a quick answer, users are offered different derivative questions to help users have a deeper insight into their PDF document. 

Pricing: 

• Start with a 3-day free trial
• Billed at 16.6/month and $199 annual plan

After payment, you will unlock these features:

• ChatGPT 4.0 Powered AI PDF reader
• Unlimited questions
• Other practical tools unlocked such as YouTube summary

Verdict:

Monica’s chatPDF requires compulsory registration to unlock its free service. Compared with Chat With PDF, this is quite inconvenient. And another flaw that hurts a little bit of the editor’s user experience is that 10 questions are limited. 

#3. Smallpdf.com

This website is a magnate company back to the days when AI is not prevailing at all. Offering basic services to split, merge, rotate, translate, convert, and extract PDF pages, SmallPDF.com harvests a large group of loyal users around the world. 

Provide suggested questions, and let you trace back to the source text in the original PDF document.

• Business: custom.

Pro features unlock after the payment:

• Unlimited download of the PDF documents.
• Ads free
• Unlock traditional PDF tools: compress, convert and digital signature protection

Verdict:

The only problem is that you cannot instantly output your summaries or answers asked by this AI PDF Reader. But the best part of this website is that its subscription is bundled sales, you can get a lot of useful features paying for a single Pro license.
