Four sample PDF files, one click each. They go through exactly the same document processing as a file of your own.
Can AI Read a PDF?
Yes. A PDF AI tool does more than open a file — it reads what is inside it. Upload a research paper, a contract, an ebook or a set of slides, and artificial intelligence works out how the PDF document is structured, can extract key insights from it and answers questions about it in the chat. The AI will read the entire document rather than the first few pages, and the original PDF stays on screen the whole time, so you can check anything the AI tells you against the page it came from.
How to Use AI to Read a PDF
- 01
Upload your PDF document
Drag a file in or pick one from your device. The AI reader supports PDF, DOCX, TXT, PPTX, EPUB and FB2 files, up to 30 MB each.
- 02
Read the AI summary
The AI goes through the entire document and lays out the key points. The original PDF stays open beside it, so nothing is taken on trust.
- 03
Chat with your PDF
Ask for a specific chapter, an explanation of a term, or a translation. Use AI chat in whatever language you prefer.

Upload a PDFWhat This AI Assistant Can Do With Your PDF Files
Chat with any PDF
Ask questions in plain language and get instant answers drawn from the PDF you uploaded, not from the open web. Chat with PDFs the way you would with a colleague who has already read them, and this PDF chat takes follow-up questions for as long as you need them.
Summaries in seconds
A long report becomes a short brief that keeps the argument intact. It summarizes PDFs instantly, and long PDFs are read whole. Ask for a tighter version, or expand a single section when you need the detail.
Any language, both ways
Upload a document in one language and translate text into another. The language of the file and the language of the answer are independent of each other.
Document and chat, side by side
The viewer sits next to the conversation, so you never lose your place. Check any claim the AI makes against the original document it came from.
AI OCR for Scanned PDF Documents
Not every PDF holds selectable text. Pages that were scanned or photographed are images, and an ordinary PDF reader has nothing to read on them. AI OCR can extract text from scanned pages first, and from that point the file behaves like any other: summarized, searchable, open to questions. A contract photographed on a phone, a library scan of a single chapter, or an invoice that came off a scanner all work.
PDFs and Other Documents That Work Here
Research papers
Methods, results and conclusions pulled out first, so you can decide whether the full read is worth it.
Books and ebooks
EPUB and FB2 alongside PDF. Chapter-by-chapter summaries for long reads.
Contracts and legal
Find a clause, get it explained in plain language, and check it against the original.
Slides and decks
PPTX goes in the same way a PDF does. Useful for lecture decks and conference talks.
Reports and notes
Quarterly reports, meeting minutes and working drafts in DOCX or plain TXT.
Scanned documents
Pages that are images rather than text are read with OCR, so an old contract photographed on a phone still works.
Who Uses This AI Tool
Students
Turn a week of PDF reading into an afternoon before the exam. Summarize the lecture deck, then go back into the chat for the parts that did not land the first time. It can help with homework by explaining a passage rather than only shortening it.
Researchers
Triage papers quickly. Read the methods and conclusions in your own language and decide in minutes whether the full text earns your afternoon.
Professionals
Work faster on contracts, proposals and reports by reducing each one to what you have to act on — with the specific clause or number findable through the chat.
What Does an AI PDF Reader Cost?
Most free PDF AI tools are free until they are not: a couple of documents a day, a page cap, or a sign-up wall before you see a result. This online PDF reader has no such wall. Here is how that compares.

Frequently Asked Questions
What is an AI PDF reader?
A tool that opens a PDF document and reads its contents, rather than just displaying the pages. This kind of AI PDF assistant can summarize the document, answer questions about it and translate it, using the text of the file itself as the source.
Is it really free?
Yes, completely free. There is no paid tier, no subscription and no payment page anywhere on the site. You also do not need an account — open the page, upload a file, and start.
How much do AI PDF readers cost?
Most charge somewhere between a few dollars and thirty dollars a month once you pass the free tier, which is usually one or two documents a day. This one has no paid tier at all, so there is no limit to run into.
What is the best free AI PDF reader?
Three things matter more than the interface: whether it handles the language of your document and the language you want to ask in, how tight the free limit is, and whether you can ask follow-up questions after the summary. An AI tool that only produces a summary leaves every unclear passage unclear, however many other AI features it lists.
How is this different from ChatGPT?
ChatGPT is a general assistant where documents are one feature among many. This is an AI-powered document assistant: the AI summary starts as soon as the file is uploaded, the PDF stays visible during the conversation, and there is no login or usage cap.
What file types can I upload?
PDF, DOCX, TXT, PPTX, EPUB and FB2, up to 30 MB per file. Word documents and PowerPoint decks go in exactly the way PDF files do — there is no need to convert anything first.
Can it read scanned PDFs?
Yes. Pages that are images rather than selectable text are put through OCR first, which extracts the text from scanned pages, so a contract that was scanned or photographed can be summarized and searched like any other document.
Can it summarize a long document?
Yes. Long PDFs of several hundred pages can be uploaded whole, without splitting them by chapter, as long as the file is under 30 MB. After the summary appears you can ask for a more detailed version of any one section.
Does it work in languages other than English?
Yes. The AI reads documents in all major languages, and the language of the answer is independent of the language of the file. Upload something in German and ask for the summary in Spanish.
Is my data safe?
Your document is processed to produce the summary and answer your questions, and is not kept as a stored file afterwards. It is never published, sold or used to train models. The privacy policy sets out which processors are involved and what rights you have, and privacy and security are covered there in full.
Do I need to install anything?
No. This is an online PDF reader, so you read PDF files directly in your browser, on Windows, macOS, Linux, Android and iPhone. There is no desktop app to download.
Does it work on a phone?
Yes. The reader and the chat both adapt to a small screen, so you can upload a PDF document and work through it from a phone or tablet.
Can I use it without creating an account?
That is the default. There is no sign-up step at any point, and nothing to verify by email before you can read your first document.

No account, no install, no limit on how many PDF files you read.
