Doing so will help you get an idea of the topics discussed on different pages. When asking questions, add particular page numbers or section titles within prompts to get more accurate responses.

FAQs Related to AI PDF Chatting Tools

  1. Is it safe to upload sensitive documents to online AI chatting platforms?

Generally speaking, online AI PDF chat tools are not considered safe, as you have to upload sensitive documents on their servers. However, most reputable offline AI platforms prioritize user privacy and data security.

So, we recommend you utilize offline tools for highly sensitive documents, such as medical records and financial reports. Afirstsoft is one such offline tool that provides the utmost security to users for a secure chatting experience.

  1. How accurate are AI responses when querying a PDF?

The accuracy of the AI responses depends upon various factors, including the complexity of the document and the quality of the text extraction. In addition, the response quality relies on the specificity of the questions you have asked.

Generally, AI provides valuable insights when it comes to questions related to the uploaded PDF content. However, you need to verify critical information manually to avoid any fabricated facts and figures.

  1. Can AI handle all types of PDFs, including scanned documents?

Most AI tools support almost all types of PDFs to let you interact with the content for better comprehension. However, while dealing with scanned PDFs, you need to find a tool with built-in OCR technology. Now, there are AI-integrated OCR tools available that can help you recognize handwritten text within PDF for document interaction.

  1. Which is the best AI PDF chatting tool?

Many online and offline AI-powered PDF chat tools are available in the market, but most lack advanced features. Among these competitors, Afirstsoft stands out as the top choice, offering a comprehensive range of AI capabilities.
