Very simple, effective, and surprisingly quick. Plus, there's a summary section built in - the chatbot is just for specific questions. The coolest part is that the summary can be copied, and you can ask another AI to expand on it (I used Grok fast mode but the OG summary was a good size too).

I have subscribed and sent you 4 emails but you have not resolved the issue. I am not able to use your app after payment also. Upon logging in the page asks me to subscribe and pay. Secondly your app does not give any details of logging in from other devices. Neither from pc or tablet. Please refund me my payment for subscription to your app. It does not work on android also. You should reply my emails.

Hi Waseem, it’s an app on PlayStore, I don’t know why you think you’d be able to use it on computer.

Two stars as a nod to the idea / potential of this app, and it's lack of input length limits. Otherwise unimpressed. e.g. ..last night I submitted a short document and asked it to count the number of times a specific string of text appears. (The correct answer was 20) It counted 10. When I said that was incorrect , it came back with 7. Then 8. Asked it another question, and it suddenly claimed to not know the doc to which I was referring. Frankly the app seems clueless, often

Hello John, Thank you for your feedback. I apologize for the confusion. ChatPDF is designed to interpret and provide information from documents, using semantic search to focus on relevant sections related to your query. It doesn’t retain full document awareness, affecting tasks like counting specific text occurrences. We value your input and will.
