Turn rough software ideas into specs your AI coding agents can follow.

MySpec is a cloud-based spec-driven development tool for software builders using AI coding agents. It interviews you about a project, then produces a structured specification bundle that can be exported to tools such as Cursor and Claude Code or accessed through MCP.

Agenticness = how independently a tool can take action, scored across 9 dimensions. Scored independently by David Kooi, Skylark Creations — see full rubric → Last re-evaluated 28 September 2026.
