The method
Markdown Prompting is the practice of writing AI prompts as structured markdown documents — clear H2 sections for the task, constraints, output format, and success criteria — instead of a single run-on sentence. Models like Claude, GPT, and Gemini follow structured markdown prompts more reliably because every requirement sits under its own labeled heading rather than buried mid-paragraph.
The Prompt Expander turns any rough idea into a Markdown Prompting document automatically — and unlike other prompt generators, it refuses to pad. No invented requirements, no “world-class expert” role-play filler. Everything it guessed is labeled under Assumptions, so you can edit or delete its inferences and keep the intent yours.
