Compare URLs side-by-side
compareRead-onlyIdempotent
Fetch 2-5 URLs concurrently and return per-URL excerpts, enabling side-by-side evaluation of multiple sources against a single question in one round trip.
Instructions
Fetch 2-5 URLs concurrently and return per-URL excerpts so the LLM can compare them against a single question in one round trip.
Best for:
- Side-by-side product/feature/article comparisons.
- "Compare X to Y" or "How does A differ from B" queries.
- Triangulating a fact across multiple sources.
Not recommended for:
- >5 URLs -> use `fetch_batch`.
- 1 URL -> use `fetch`.
- Don't have URLs yet -> use `search` or `research` first.
Returns:
- markdown (default): a comparison brief with per-URL sections, each
containing title, sitename, published date, and a smart-truncated excerpt.
- json: {question, urls, excerpts:[{url, title, excerpt, ...}],
tokens_estimated}.
Common mistakes:
- Asking `compare` to actually answer the question — it returns material,
the LLM does the comparison.
- Passing >5 URLs and expecting them all to fit in context — use
`fetch_batch` for bulk reads.
Args:
question: The comparison question the LLM will answer using the
returned excerpts.
urls: 2-5 absolute http(s) URLs.
format: "markdown" (default) or "json".
