Search tools head to head — Genspark web_search vs Claude Code WebSearch
Head to head
Same question, and two thirds of the answer differs. Neither tool alone can tell you what page one looks like.
Put the same three questions (two English, one Korean) to both tools and compared which domains came back on page one
10 / 30domains both tools returned
Where they differ The differences run in a clear direction. Genspark gave eight of twenty-eight slots to Reddit and Quora; WebSearch gave one of twenty-five. The Korean question splits them further — Genspark returned five Naver blog slots plus AdPost's own help page, while WebSearch returned no Naver blogs at all and spent four of nine slots on Google Ad Manager documentation about native ads, which has nothing to do with the question.
How we measured One run per question per tool, comparing only the set of domains on page one. Rank and titles were ignored — the question was simply which sites appeared. Repeat appearances of a domain counted once.
Not measured We did not judge which set is more useful. This record only says the two disagree. Whether either tool repeats itself on another day is a separate question.
