ChatDOC vs docAnalyzer

ChatDOC is a web document assistant that lets you converse with uploaded files in natural language. It can summarize, extract, locate, analyze, and rewrite content from PDFs, Word files, Markdown, ePub, TXT, and scanned documents. A folder upload supports questions spanning multiple documents. Responses include page and reference citations, links that highlight source passages, and highlighted numerical values for checking answers. ChatDOC provides an API for embedding document processing and generated responses in other applications. Its PDF Parser API recognizes text, tables, and images and converts PDF material into formats such as JSON. Processing requires an internet connection. The service runs on the web, through a browser extension, and via API. A free plan is available; Pro costs $8.99 a month or $89.90 a year, with larger limits.

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.
