Markdown Studio

Maker

📌

Hey Product Hunt! 👋 I built Markdown Studio because I was frustrated switching between my markdown editor, ChatGPT, and Claude just to iterate on prompts. The core idea: your markdown IS your prompt. Write it, fill in variables, then run it against GPT-4o, Claude, Gemini, or Llama side-by-side in Battle Mode to see which model handles it best. What makes it different: - Zero-knowledge architecture — there are no servers. Your content, API keys, and data never leave your browser. This isn't a privacy policy, it's an engineering constraint. - Battle Mode — run the same prompt against 2+ models simultaneously, compare streaming responses, see token costs, and rate the outputs with stars. - PromptOps — lock your prompt configuration, certify outputs with SHA-256 hashes, and detect drift when you re-run. Think version control for AI outputs. - 187 features — full CodeMirror 6 editor, Mermaid diagrams, KaTeX math, GitHub sync, audit logging, PII scanning, variables with presets, and 8 languages. It's completely free. No login required. I'd love to hear what you think — especially what workflows you'd want to see next!

GitHub Integration within Markdown Studio - Edit markdown without losing work

Today we re launching GitHub integration for Markdown Studio a markdown editor that syncs safely with Gists and repos, without the usual where did my work go? moments.

Most markdown files already live in GitHub READMEs, docs, design notes, drafts, wikis.
But editing them still feels clunky:
