KitRank is a free library of real AI agent use cases. Each one comes from a creator, builder or operator who actually shipped it, links to the original source, and is rewritten as a recipe: what it costs, how long it takes, how hard it is, and a setup prompt you can paste into Claude Code, Codex or Grok Bot. There are 1,900+ use cases across eight categories, plus 137 step-by-step how-to guides. The Daily 5 email sends five new use cases every morning. A free, read-only MCP server lets your agent search the catalog directly.
