ChatDOC digs into the tables and formulas other PDF chatbots skip
ChatDOC is an AI reading assistant for documents: you upload a file, ask questions, and every answer comes with footnotes pointing back to the exact source passage. The team behind it previously built document tools for financial clients, which explains how well it copes with dense tables. Over 500,000 people run it on the web or through the Chrome extension. Two files a day cost nothing, and the Pro plan is $8.99 per 30 days.
Pros
- Every answer segment carries its own citation
- Sharp handling of tables and formulas
- Targeted questions on a selected passage
- Chat across a whole folder of files
Cons
- OCR restricted to English and Chinese scans
- Free tier capped at 20 pages per file
- Mobile experience still early-stage
Answers you can verify line by line in ChatDOC
ChatDOC attaches a footnote to each segment of its answers: you click it, the page opens, and the source passage shows up highlighted. Checking whether the AI made something up takes seconds instead of a re-read.
The other trick is direct selection. You highlight the cash-flow table in an annual report, ask what explains the gap between two years, and the answer stays locked on that spot. The same works for a math formula you want explained in plain words, or a paragraph to translate. Follow-up questions keep their context in a thread, so you can push until it clicks.
- PDF and Word documents (.doc/.docx)
- Markdown, ePub, TXT
- Scanned files (OCR) and website content
- Whole folders, queried in a single conversation
ChatDOC Studio in action: a chatbot built from your documents
From thesis chapters to company chatbots
People buried in long documents get the most out of it: students turning lecture PDFs into exam questions and flashcards, lawyers combing through contracts, analysts cross-reading several reports. Traceable citations matter a lot in academic work, a key criterion behind the best AI picks for students.
The company also launched ChatDOC Studio, a no-code platform aimed at businesses: feed it your files or website and it builds a support or onboarding chatbot, embeddable through a floating button, iFrame or API. A PDF parser converts documents into structured, model-ready data.
ChatDOC free vs Pro, the line in numbers
Pro costs $8.99 per 30 days on auto-renewal ($16.99 at list price) or $89.90 for 360 days, with add-on packs at $0.29 per file or $0.06 per page. It also switches on optical character recognition for 500 scanned pages a month, plus optional access to OpenAI's latest models through a separate quota. Those figures shift with promotions, so treat the subscription page as the reference.
The free tier works best as a test bench (long enough to confirm that a messy multi-column table survives the trip).
| Feature | Free | Pro |
|---|---|---|
| Files | 2 per 24 h, 10 total | 300 per 30 days |
| Pages per PDF | 20 | No limit |
| Questions | Reduced quota | 300 per 24 h |
| Scanned files (OCR) | No | 500 pages per 30 days |
| Formula recognition | No | Yes |
Frequently asked questions
Is ChatDOC free?
Yes, a free tier exists: 2 files per 24 hours, 10 files in total, and a 20-page cap per document. Lifting those limits, along with OCR and formula recognition, requires the Pro plan at $8.99 per 30 days or $89.90 for 360 days.
Is ChatDOC better than ChatPDF?
On sourcing, yes: ChatDOC places citations inside each answer segment and lets you select a table or formula to question directly, while ChatPDF only cites page numbers. Price is another gap, with ChatPDF Plus at $19.99 per month against under $9 for ChatDOC Pro.
Is ChatDOC safe for confidential documents?
According to its privacy policy, ChatDOC does not collect uploaded documents to train its models, though it stores standard account data such as name, email and payment details. Institutions reviewing the tool still advise keeping genuinely sensitive files off it, a sound habit with any cloud service.
Can ChatDOC read scanned documents?
Only on the Pro plan: OCR covers up to 500 scanned pages per 30-day period and currently supports English and Chinese documents. A scan in another language has to be converted to text before uploading.
Verdict: Table-heavy annual reports are where ChatDOC earns its keep; PhD students, analysts and legal teams stand to save whole afternoons of reading, starting with the free tier.
