AI TOOL · DEEPSEEK
Chat with PDF
Upload a text-based PDF and ask a focused question. The answer is limited to the document text, and the file is not stored after the request.
This AI tool is waiting for server setup.
The page and the request handler are ready, but the server setup is incomplete. AI text tools need a DeepSeek API key. PDF tools also need MuPDF (mutool) for text extraction. Until the setup is complete, the form is disabled and this page is excluded from search results.
How it works
DeepSeek processes it
The server sends a focused instruction and the text to DeepSeek. The API key is never exposed to the browser.
Review the result
The answer appears on this page. Copy it if useful, and check it against the source before you rely on it.
Limits and expectations
This is a single-question tool, not a persistent chat. The document text is sent to DeepSeek for the answer.
Requests are rate limited. The service is free within the current limits and may be paused if capacity is exhausted. This site does not store the submitted text or the result after the request.
The PDF must contain selectable text. A scanned document needs OCR before it can be summarized or queried.
AI processing is provided by DeepSeek. Read the privacy notice before submitting sensitive material.
Frequently asked questions
What kind of PDF works best?
A text-based PDF exported from an office application or a digital document. Scanned image PDFs need OCR first.
Does it read the whole PDF?
It reads only the first 40 pages and up to 12,000 characters.
Is this a conversation?
No. This tool answers one question per PDF upload. Start a new request for another question.
Does it keep my PDF?
The uploaded PDF is a temporary file removed after the request. The extracted text is sent to DeepSeek for the answer.
