What each tool is
BigSpy is a very large multi-platform ad archive at a low price: Facebook, Instagram, TikTok, YouTube, Pinterest, Twitter, Yahoo and Unity, with a base plan around $9 a month. It is a keyword-and-filter library at scale.
Klayson is Meta only and goes deeper on each ad: a model reads the hook, angle, offer, format and who appears, watches the videos, and the search understands what you mean. Ranking puts the top performers first by run time and versions, questions come back with charts, and the same data feeds a creator search and a remix.

Where BigSpy is better
Breadth and price. If you need YouTube or Pinterest ads, or a quick look across every platform for under ten dollars, BigSpy is the sweep.
Where Klayson is better
Depth on Meta. Knowing that an ad has run 300 days with 12 versions, what its hook is, what the video says, and which creator is in it, then asking the next question, is what Klayson is for. BigSpy shows you the ad; Klayson tells you why it is still running.
