As answered by people managing DeveloperToolStack and KissMySkills.
KissMySkills's answer:
Freelancers, agencies, marketers, sales teams, and small business owners who use AI daily but don't want to spend time writing and testing their own prompts - they want a ready-made result for a specific role or task.
KissMySkills's answer:
Shopify (storefront and checkout), with skill files packaged as Markdown/SKILL.md format compatible with Claude, ChatGPT, Gemini, and Copilot.
KissMySkills's answer:
We package prompts and workflows as ready-to-use skill files instead of raw text - buyers get a tested, structured deliverable (SKILL.md + examples) they can drop into Claude or ChatGPT and use immediately, not a prompt they still have to tweak and test themselves.
KissMySkills's answer:
Most prompt marketplaces sell single prompts with no guarantee they'll work. We sell tested skill files and agents across 289 role-based skills, 119 prompt packs, and 35 agents, backed by a 30-day money-back guarantee, and we also offer 46 free generators so people can try the format before paying
KissMySkills's answer:
KissMySkills started from a simple frustration: rewriting the same prompts from scratch every time a new AI task came up. Instead of solving that just for ourselves, we built a marketplace where anyone can buy a ready-made skill or prompt for their exact use case - and where people who build good prompts can sell them instead of leaving them in a doc.
