Primer · marketplace vs directory

What's the difference, and which do you need?

An AI agent directory is a catalog. The job is to list every relevant tool or agent and let you search or browse. There's An AI For That and FutureTools are textbook directories — broad, SEO-driven, and best for the initial "what's even out there?" scan.

An AI agent marketplace goes further: structured metadata, comparison, reviews, and often the ability to run or deploy the agent. Agent.ai, AgentVerse, and PolarAgentHub fit here. You use a marketplace when you've moved past discovery and need to pick one.
