Rough idea in. Clear prompt out.

The Prompt Expander turns a one-line idea into a structured Markdown Prompting document, with every guess labeled so you stay in control. No “world-class expert” padding: if your prompt is already good, it comes back nearly unchanged.

Structured, honest about its guesses, and biased against bloat — if your prompt is already good, we'll barely touch it.

The method

What is Markdown Prompting?

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.

01Sections beat sentences. A markdown prompt with Task, Constraints, and Output Format sections gives the model unambiguous instructions to check itself against.
02Labeled guesses keep you in control. Anything the expander inferred lands in an Assumptions block you can edit — not silently baked into your prompt.
03Clarity, not length. A good prompt comes back nearly unchanged. Markdown Prompting is about structure, never word count.
