When doing AI-first development, I found myself waiting for the AI to finish executing and started planning the next prompt in generic markdown editors. But those editors had no specialization for prompt planning. So I built Prompt Planning — a notebook-style app designed specifically for planning AI prompts, with a rich editor, token estimation, templates, context snippets, and drag-to-reorder.
Prompt Planning is live and free to use. It removes the friction of switching between generic text editors and AI tools, keeping developers one step ahead of their AI workflow.
