Why it deserves attention
MAYBESearch demand exists and retail pricing leaves room to investigate. Competition evidence is incomplete enough that one targeted research mission could still change the decision.

FROM NOISE TO A TESTABLE DECISION
Research only what can change the answer.
SellAnything does not send every product to an expensive generic agent. It asks the cheapest next question that can still change the decision.

Test
Move forward with explicit evidence, risks and kill rules — not model vibes.
THE AGENT RESEARCHES. THE ENGINE DECIDES.
