FAQ
Tags describe a tool's core capability, workflow fit, or commercial attribute so you can filter more precisely than a broad category.
Categories group tools by broad product area. Tags capture specific signals such as free plans, developer workflows, agents, citations, or team use.
Use tags when you already know the capability you need. Use search when you are looking for a specific product, workflow, or brand.
