for developers
10x your dev efficiency in the AI era.
From spec writing to launch prep — tools for every stage of AI-powered development, organized by when you need them.
Why these tools
AI made development faster. But spec writing, environment setup, multi-task management, remote checking, and launch prep still slow you down. Here are tools that help at each stage.
Lock the spec first
Before vibe coding, nail down the spec. AI tends to break when you build incrementally without a solid plan. The more detailed your spec upfront, the smoother the build.
Shape a solid spec by talking it through with AI.
DesignFrom spec brainstorming to document creation. AI asks the right questions to help you build a thorough, gap-free spec.
