AI PDF Assistant
Upload a PDF and ask questions about it
What is AI PDF Assistant?
AI PDF Assistant is a free AI tool from Farvixo that helps you upload a PDF and ask questions about it. Text is extracted from your file in the browser and then sent to a language model to be processed. No API key and no account are required, and responses arrive as they are generated rather than all at once.
How to use AI PDF Assistant
Add your file to AI PDF Assistant. The text is read out of it in your browser, then sent to the AI model so it can answer.
AI PDF Assistant streams the response back as it is generated, so you can start reading immediately instead of waiting for the whole answer.
Ask follow-up questions to narrow the result, then copy it or download it. No API key and no account are required.
Frequently Asked Questions
How does AI PDF Assistant work?
Upload a PDF, then ask questions. AI reads the document text and answers from its content only.
Does it work on scanned PDFs?
Best on text-based PDFs. For scanned documents, use PDF OCR first, then chat with the searchable PDF.
Is it free?
Yes — 100% free, no API key required. Same free AI as the header AI Assistant.
Is my PDF uploaded anywhere?
Your PDF file itself never leaves your device — the text is read out of it right in your browser. To answer your question, that extracted text is then sent to the AI model, the same as if you had pasted it into a chat. Nothing is stored afterwards. For confidential documents, keep that in mind before uploading.
What can I ask it about my PDF?
Summaries of the whole document or a section, key facts and figures, what a table contains, action items, deadlines, names and dates, or plain-language explanations of dense passages. Answers come only from the document, not from the open web.
Does AI PDF Assistant work on mobile?
Yes — upload a PDF and chat with it from any modern browser on Android or iPhone, exactly as on desktop. No app or account needed.

Tips for better results
- Say who the output is for and how long it should be. Specific constraints produce far better results than an open request.
- Treat the first answer as a draft and refine it with follow-ups rather than re-typing the whole prompt.
- Always check facts, figures and citations yourself — a language model can state something wrong with complete confidence.
Common problems and how to fix them
The answer stopped part-way through
The response hit its length limit. Ask it to continue, or split the request into smaller parts.
The result is generic or off-target
The prompt left too much open. Add the audience, the format, the length and an example of what good looks like.
The tool declined the request
The prompt crossed a safety boundary of the underlying model. Rephrase it, stating the legitimate context and purpose.
