The agent successfully understood the product from a single homepage fetch. The site clearly presented what Markdown Peek does, who it serves, pricing (free), and key features, but offered no explicit comparison to competitors or detailed positioning against alternatives, requiring the agent to infer differentiation from feature descriptions.

• ›Single-page fetch sufficed: The homepage was information-dense and self-contained, requiring no navigation to secondary pages. All task requirements (what, who, how priced, how different) were answered from [1].
• ›Site is machine-readable and well-structured: The response was presented as clear markdown sections with bullet points, making facts easily extractable and summarizable.
• ›Differentiation had to be inferred: The site highlights features (Quick Look, offline rendering, Mermaid/LaTeX support) but does not explicitly name or compare against competing markdown viewers. The agent attributed differentiation to feature positioning rather than direct competitor comparison.
• ›No comparison table or alternatives section: The agent noted this as a minor gap—someone unfamiliar with markdown viewer ecosystems would not learn whether Markdown Peek is faster, cheaper, or more capable than Preview.app, MacDown, or others.
• ›System requirements noted but not in final answer: The fetch revealed macOS 15.5+ requirement, but the agent did not emphasize this as a potential barrier despite it being material for adoption.
