AI SEARCH & RESEARCH
Exa
Paid links. We earn a commission if you buy through links on this page. It never changes our ranking — see how we rank.
Pricing
We do not reprint prices. They change too often for that to be honest, and a number on our page with no date is worse than sending you to the source.
How we rated it
What it is
A search engine built around meaning rather than keywords, intended for AI applications: you describe what you are looking for and it returns pages that match the idea.
Who it is for
Developers doing research-style retrieval where the right page does not contain the obvious words.
Where it is strongest
Finding things keyword search misses — companies like this one, papers about this idea, pages similar to this page.
Where it falls short
Worse than a keyword engine for exact lookups, which is a real limitation when you need a specific fact. Priced per search. And the index is narrower than the general engines.
Our verdict
Recommended for semantic research. Pair it with a keyword search rather than replacing one — they fail in different directions.
Editorial assessment. We earn a commission on some links; it does not change the ranking.
