Curated Skills marketplace

Browse thousands of agent Skills grouped by category — research, video, finance, marketing, coding, legal, productivity and more — with ratings and sales counts visible.

Run Skills online

Many listings can be executed directly in the browser, so you can test a Skill's output before subscribing rather than guessing from a description.

Creator storefronts and payouts

Flexible listing pricing

Skills are sold per month, per week or as free trials, letting creators match price to how often a Skill is actually used.
