Traditional PDF readers force you to scroll, search, and scan manually—wasting time and energy. With an AI-powered PDF chat tool, you can instantly interact with your documents using natural language. Whether you’re reviewing research papers, legal contracts, user manuals, or reports, simply upload the file and ask questions. The AI reads and understands the content, delivering accurate answers, smart summaries, and faster insights—no manual reading required.
Chatting with your PDFs in Fello AI is fast, intuitive, and designed for deep document understanding—without the need to manually read or search. Here’s how it works:
You can upload up to 16 PDF documents at once to Fello AI, even if they’re hundreds of pages long. Whether you’re working with research papers, business reports, or legal contracts, Fello AI handles large files effortlessly.
Once uploaded, your document appears in a clean, scrollable sidebar. This gives you full visual access to the content while you chat with the AI—so you can reference, navigate, and interact with the file in real time.
Just type your questions naturally, like:
The AI reads the full document instantly and responds with accurate answers, detailed summaries, and contextual understanding—within seconds.
Academic papers can be dense and time-consuming to read. With AI PDF chat, you can quickly get summaries of key findings, methods, or conclusions.
Just upload the document and ask direct questions like “What are the main takeaways?” or “What was the outcome of the study?”
Contracts and agreements are full of fine print. AI PDF chat helps you pull out important sections like payment terms, responsibilities, and clauses.
Instead of reading line by line, simply ask, “What are the termination conditions?” or “Is there a non-compete clause?”
Market reports, financial statements, or annual summaries can be overwhelming. AI makes it easy to extract the most relevant insights.
Upload your file and ask things like “What are the revenue trends?”, “What’s the outlook for next quarter?” or anything else you’re curious about.
Technical manuals can be hard to follow, especially when you just need one answer. AI PDF chat gives you quick, clear instructions.
Ask questions like “How do I install this?” or “Where is the reset button?” and get right to the point.
Medical documents often use complex terminology and long explanations. AI PDF chat helps simplify that content into plain language.
It’s great for quickly understanding treatments, results, or clinical data by asking specific, focused questions.
New employees often have to dig through handbooks and internal PDFs. With AI chat, they can ask questions and get answers in seconds.
From “How do I request time off?” to “What’s the reimbursement policy?”—everything becomes more accessible.
Fello AI is built with a privacy-first approach to help you interact with your PDF documents quickly and securely. When you upload a file and begin chatting, the content is processed in real time using advanced AI models such as ChatGPT, Claude, o Gemini, enabling fast and intelligent responses based on your document.
We never analyze your documents beyond what’s needed to generate the responses you see. Your files are handled in-session only, and document interactions happen directly in your browser, giving you full control over your experience.
Because processing is powered by third-party AI services, it’s important to understand that your document data is temporarily shared with those models. While most providers have policies in place to limit data usage, this may vary by platform or usage tier.
