Who it's for

Users who need to query numbers inside tables, like financial statements or experiment results. It recognizes tables accurately, unlike other PDF tools that often flatten them into plain text.
Users who want to run OCR on scanned image PDFs to ask questions. It is useful for digitizing and working with older materials.
Users who want to verify answers with source highlights. Clicking a citation instantly highlights the relevant table or paragraph in the original document.

The free plan has low document and query limits, making a paid plan necessary for regular use. It is best suited for testing with one or two files.
Operated by a Chinese company, so you should review its data processing policy before uploading sensitive documents.
The interface is only in English and Chinese, which may feel unfamiliar to beginners. Korean queries and answers work, but UI menus remain untranslated.

Sign up on the official website and upload a document. Turn on the OCR option for scanned PDFs.
Once processed, ask questions in Korean in the right-side chat panel. Example: "What is the 2025 revenue in the table on page 2?"
Click the citation in the answer to view the highlighted table or sentence in the original document.
To query multiple documents together, create a collection and upload them. Example: "Combine the revenue tables from these three reports into one."
When you reach the limit, check the pricing page for the Pro plan. Review the data processing policy before uploading sensitive files.

ChatPDF Free plan ChatPDF is simpler and requires no login, but ChatDOC is better for querying numbers inside tables.
Gemini Notebook Free plan NotebookLM offers generous free limits and sentence-level citations, but its table interpretation is weaker.
AskYourPDF Free plan AskYourPDF has tight daily document limits, while ChatDOC excels at reading table-heavy documents.
