Do I always need a Firecrawl key?

No, only for fetching URLs. The 'paste content directly' expander reviews pasted markdown or text with just your Anthropic or OpenAI key, so you can skip Firecrawl entirely if you already have the content.

Why is some of my page missing from the review?

The Firecrawl scrape uses onlyMainContent plus an includeTags whitelist of h1-h6, p, li, table and blockquote. Text in other elements (divs, spans, accordions rendered without those tags) and anything Firecrawl classes as navigation or ads never reaches the model, so it cannot be reviewed. Paste the content directly if coverage matters.

Can the annotated output get cut off?

Yes. The review call is capped at 8,000 output tokens, and because the output repeats your full content with annotations inserted, long pages can hit the cap and lose the end of the review, including the summary section. Review very long pages in parts via paste mode.

What are the limits and pacing in bulk mode?

Bulk runs are capped at 50 URLs per run (slider, default 10) with a fixed 2 second pause between URLs. Each URL costs one Firecrawl scrape plus one LLM call over the full fetched content, so token spend scales directly with page length.

Are the annotations machine-readable?

They are HTML comments inserted into the markdown (ISSUE, MISSING, STRENGTH, IMPROVE, SEO), which means they are invisible when the markdown is rendered but easy to grep or parse from the downloaded file.
