Why teams use this tool
Live preview, exports, and templates matter most when you are drafting long-form docs without leaving the browser.
Live preview as you type
See headings, tables, and code blocks render instantly — no save button, no server round-trip.
Export stakeholders can open
Download PDF, Word, HTML, or raw .md from the same source file your team reviews in Git.
Templates for READMEs and prompts
Append structured sections for install steps, API refs, and AI system prompts without starting from a blank file.

Use cases
Who opens the editor first versus a specialized conversion tool.
Developers
Draft README files, changelog entries, and internal docs with fenced code blocks that stay valid.
Technical writers
Review rendered output before exporting to PDF or Word for stakeholders who do not read raw Markdown.
AI workflow authors
Structure system prompts and context files with headings and lists that LLMs parse reliably.
Frequently asked questions
Is the Markdown editor free?
Yes. Live preview, templates, and core exports are free with no account required.
Does my content leave my browser?
Drafts auto-save to local storage on your device. Exports download directly — nothing is uploaded for editing or preview.
What can I export?
Raw .md, PDF, Word (.docx), and self-contained HTML — all generated client-side.
Does it support GitHub Flavored Markdown?
Yes. Tables, task lists, fenced code blocks, and strikethrough render in the preview pane.
How is this different from the tool pages?
The editor is the full writing workspace. Tool pages handle specialized conversions like HTML → Markdown or README assembly.
