ChatPDF vs docAnalyzer

ChatPDF lets users summarize documents and ask questions about their contents using conversational AI. Answers include citations that point to references in a PDF, and users can organize files in folders or discuss multiple PDFs in one conversation. It accepts PDFs in any language and supports conversations in any language; listed file types also include Word, PowerPoint, Markdown and text. Sharing links can be created, with access permissions managed or revoked. ChatPDF says documents are encrypted during transfer and storage and can be deleted by the user. Queries are routed dynamically between GPT-4o and GPT-4o-mini. The service works in a browser on any device and is listed for Android, iOS, Linux, macOS and Windows. Its backend API accepts uploaded PDFs or public URLs and lets users query them to build custom PDF chatbots. The API documentation limits each PDF to 2,000 pages or 32 MB and describes the chat API as stateless. The Free plan costs nothing and allows two documents per day.

docAnalyzer is a source-grounded AI workspace for analyzing documents and producing deliverables. Ask docAnalyzer handles requests across a workspace, Focus chat works with selected sources, and Co-work chat supports editing notes. Cited claims can link to a page, section, or spreadsheet cell in the source viewer. Batch workflows cover data extraction, per-document questions and summaries, reference audits, rewrites, and SEO metadata. It can OCR scanned pages in more than 40 languages and generate downloadable PDFs, spreadsheets, charts, diagrams, and ZIPs. Inputs include PDFs, office documents, EPUB, spreadsheets, text, HTML, and web pages; standalone image, audio, and video uploads are unsupported. Paid plans can import selected Zotero or Mendeley references, but Google Drive and OneDrive connectors are unavailable. The API is available on paid plans. The free Community plan includes monthly credits and upload limits, without API access. Paid plans start at $8 a month.
