Offline prompt builder

Offline prompt building for AI coding workflows

MarkupHTML helps you prepare AI coding prompts from local website files.

Use it to open local HTML or a site folder, mark what needs to change, and export a clean prompt. The prompt is plain text, so you can paste it into ChatGPT, Codex, Cursor, Claude, or another assistant.

No AI inside

MarkupHTML does not upload your project to an AI model, call an AI API, or generate code. It helps you prepare the instructions.
