Feature & Specification Comparison
Tools & Capabilities Breakdown
Citation Check Tools (2)
check_citation
Fetch a URL and report whether it exists, and whether the source names the same entity as the claim you attach to it. These are two different questions and conflating them is the failure this exists to catch: a URL can return 200 and describe a different gene entirely. No account needed, nothing is stored about you.
verdict_meanings
The exact semantics of every status and relevance value, including what this checker cannot determine. Read once before trusting a verdict.
PDF Reader MCP Tools (4)
inspect
Document and media evidence when Markdown is not enough. video_timeline (bounded scene/cue timeline) and render_frame (actual decoded frames), and cite_check (quote/location support, not semantic truth), are anymd Pro; PDF operations: inspect (page facts, metadata), render_page (PNG images), extract_regions (crop bounding boxes), ocr_pages / analyze_regions (configured OCR or vision provider), structure (JSON with document map, elements, geometry; profile quality|research adds trust and accessibility reports), compare (page-level diff of sources[0] vs sources[1]).
