A spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.
You describe intent and context first; Kiro captures requirements and design as specifications, then verifies the finished implementation against them.
Kiro Crew watches your backlog, codebase, or CI, triages new work, delegates to specialized bots, and returns results for your review.
Long tasks split into checked steps so agents cannot shortcut a failed test, and review agents inspect diffs before a human approves a merge.
Use the IDE, mobile, or web, run headless in CI/CD with the CLI, or trigger Kiro from Slack, Microsoft Teams, GitHub, and GitLab.
The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
