Learn Kiro, calmly.
Kiro is Amazon's agentic AI development tool: an IDE, a terminal CLI, a web app, an iOS app, and Kiro Crew, an open-source always-on agent. This site is the free Kiro tutorial for beginners (yes, Kiro for dummies) and for engineers who want the details.

Steering
Markdown rules that teach Kiro your project's conventions.
Memory
Context Kiro learns in one session and recalls in the next, so you stop repeating yourself.
Hooks
Automations that fire on events like saving a file.
MCP
A plug-in protocol connecting external tools and data sources.
IDE
