Our verdict on ChatDOC

ChatDOC is an AI assistant for asking questions about PDFs and other documents. It suits researchers, analysts, students, and teams that need to summarize files, extract information, inspect tables or formulas, and find answers across multiple documents. Its natural-language chat supports PDFs, Word files, Markdown, ePub, TXT, scanned files, and website content. Answers include page-number and reference citations that link back to relevant document passages.

The pricing structure is straightforward. The Free plan includes PDF support with limited uploads and questions. Pro costs $8.99 per month or $89.90 per year. Both Pro billing options include 300 files every 30 days, no PDF page limit, OCR for scanned pages, and multi-document chat. The paid tier is therefore the practical choice for larger document sets, scanned material, and users who need folder-based or cross-document questions. GPT-4o question packages are also available as a listed feature.

ChatDOC’s strongest fit is document-focused analysis rather than a broad general-purpose workspace. It combines citations with OCR, table and formula analysis, summaries, information extraction, URL import, browser access, and an API. The web app, API, and Chrome extension offer several access routes, while the product remains centered on document processing. Choose ChatDOC if cited PDF answers, multi-file questions, and scanned-page support are priorities. Choose another option if your workflow depends on platforms beyond its web, API, and Chrome extension access or if limited free usage is insufficient.

I've used ChatDOC myself and this is my honest opinion — nobody paid or asked me to write it.
