Markdown Editor

A what-you-see-is-what-you-get Markdown editor in the spirit of Typora: type Markdown and the formatting renders inline, so there is no separate raw pane to keep in sync. It supports headings, bold and italic, strikethrough, inline and fenced code, blockquotes, tables, task lists, links, and images, plus KaTeX math both inline and as display blocks. A block menu (type / on a new line) and a selection toolbar keep formatting fast. Pick from fourteen themes — including GitHub, Vue, Notion, Nord, Dracula, One Dark, Tokyo Night, and a warm DevKitLab theme — switchable at any time. Your draft is kept in this browser via localStorage and you can copy or export the Markdown at any point. Everything runs locally; nothing is uploaded to a server.

  • Inline WYSIWYG editing — Markdown formats as you type, no split raw/preview pane to manage
  • Full Markdown: headings, bold, italic, strikethrough, code, blockquotes, tables, task lists, links, and images
  • KaTeX math, inline ($…$) and as display blocks ($$…$$), rendered live
  • Fourteen switchable themes (GitHub, Vue, Notion, Nord, Dracula, One Dark, Tokyo Night, and more), light and dark
  • Local-first — your draft is saved in the browser and the Markdown can be copied or exported anytime, with no upload

Overview

A focused, inline Markdown editor for writing rather than wrangling syntax. Formatting renders as you type, common structures have shortcuts, and the output stays clean Markdown you can copy or export. It runs entirely in the browser.

  1. 01

    Inline WYSIWYG editing

    Markdown formats in place as you type — headings become headings, **bold** becomes bold — so you read the document, not the syntax, while still producing standard Markdown underneath.

  2. 02

    Full Markdown coverage

    Headings, bold, italic, strikethrough, inline and fenced code, blockquotes, ordered and bulleted lists, task lists, tables, links, and images are all supported, following CommonMark and GitHub-style extensions.

  3. 03

    KaTeX math

    Write inline math with single dollar signs and display equations with double dollar signs; both render live through KaTeX, which suits notes, papers, and technical documentation.

  4. 04

    Block menu and selection toolbar

    Type a slash on a new line to insert headings, lists, tables, code blocks, or math, and select text to apply inline formatting from a small toolbar — so you rarely need to remember raw syntax.

  5. 05

    Fourteen switchable themes

    Choose from light and dark themes including GitHub, Vue, Notion, Newsprint, Solarized, Academic serif, Nord, Dracula, One Dark, Tokyo Night, and a warm DevKitLab default. Your choice is remembered.

  6. 06

    Local-first with export

    Your draft is saved in the browser through localStorage, and you can copy the Markdown or download a .md file at any time. Nothing is sent to a server.

How to use

A typical flow: start writing, use the slash menu for structure, pick a theme, then copy or export the Markdown.

  1. 01

    Start typing in the editor. Markdown formats inline as you go — for example type ## for a heading or - for a list and it renders immediately.

  2. 02

    On a new line, type a slash to open the block menu and insert a table, code block, blockquote, image, or math block.

  3. 03

    Select text to show the inline toolbar for bold, italic, strikethrough, code, and links, or just type the Markdown marks directly.

  4. 04

    Add math with single dollar signs for inline and double dollar signs for a display equation; KaTeX renders it live.

  5. 05

    Pick a theme from the bottom selector — light or dark — to match your taste; the choice is saved for next time.

  6. 06

    Copy the Markdown to your clipboard or download a .md file when you are done; your draft also stays saved in the browser.

Details

The everyday friction of writing Markdown — switching between raw and preview, remembering table syntax, getting math to render — is handled inline, with no server round-trip.

  • Inline rendering means one surface to read and edit, instead of a raw pane plus a preview pane.
  • CommonMark plus GitHub-style tables, task lists, and strikethrough are supported out of the box.
  • KaTeX renders inline and display math live as you write.
  • A slash block menu and selection toolbar make structure and inline formatting fast.
  • Code blocks get syntax highlighting and are easy to edit inside the document.
  • Fourteen light and dark themes are switchable at any time and remembered between visits.
  • Drafts persist in the browser via localStorage, so a refresh does not lose your work.
  • Copy the Markdown or export a .md file whenever you need it.
  • Everything runs locally in the browser — no account, no upload, no server processing.

Use cases

Whenever you write in Markdown, an inline editor removes the syntax overhead and lets you focus on the content.

  1. Draft READMEs and docs

    Write a project README or documentation page with live formatting, then copy the Markdown straight into your repository or docs site.

  2. Take technical notes

    Keep notes with code blocks, tables, and KaTeX math rendered inline, so formulas and snippets read clearly while you type.

  3. Write issues and pull requests

    Compose GitHub or GitLab issues and PR descriptions with tables and task lists, then paste the Markdown into the tracker.

  4. Prepare blog posts and articles

    Draft posts for a static-site generator or CMS, pick a theme that matches your reading preference, and export the Markdown file.

  5. Build checklists and plans

    Use task lists and headings to outline a plan or checklist, with the formatting visible as you organize the items.

  6. Convert thoughts to clean Markdown

    Paste rough text, restructure it visually with headings and lists, and copy out tidy Markdown ready for any Markdown-aware tool.

When you need word, character, and reading-time counts for what you have written, hand the text to Text Counter . If you need to escape or unescape Markdown that contains raw HTML or special characters before embedding it, use HTML Encoder and Decoder . And to normalize headings or titles to a consistent letter case, run them through Case Converter before copying the Markdown back here.

Best practices

An inline editor is comfortable, but a few habits keep the Markdown it produces portable and predictable.

  • Copy or export periodically. Drafts are saved in this browser only, so they do not sync across devices or survive clearing site data.
  • Check tables and math in the target system; renderers vary, and a complex table or equation may need small adjustments elsewhere.
  • Prefer fenced code blocks with a language tag so highlighting and copying behave well wherever the Markdown lands.
  • Keep images as links or attachments in your destination; pasted or embedded images are not uploaded anywhere by this tool.
  • Use the theme to suit reading comfort, but remember the theme is for editing here — it does not travel with the exported Markdown.
  • For long documents, export a .md file as a backup rather than relying solely on the browser draft.

Limitations

Knowing what the editor does not do keeps it from being mistaken for a full publishing platform or a document store.

  • It is not cloud storage or a sync service: drafts live only in this browser via localStorage and are not backed up or shared.
  • It does not render to PDF or upload images; export is the Markdown source, and images stay as the links or data you provide.
  • Math is rendered with KaTeX, which covers most LaTeX math but not the full LaTeX language or document classes.
  • It targets CommonMark plus common GitHub extensions; very niche Markdown flavors or raw HTML may not round-trip exactly.
  • It is a single-document editor, not a multi-file workspace, wiki, or version-control system.
  • Processing stays local, but local security still depends on your device, browser extensions, and where you paste the exported text.

FAQ

Common questions cover how editing works, math, themes, where drafts are stored, and whether anything is uploaded.

Is this a WYSIWYG editor like Typora?

Yes. Markdown formats inline as you type, so you edit the rendered document rather than a raw pane next to a preview. Underneath it is still standard Markdown, which you can copy or export at any time.

How do I write math?

Use single dollar signs for inline math, for example $E = mc^2$, and double dollar signs on their own lines for a display equation. Both render live through KaTeX, which supports most common LaTeX math.

How many themes are there and are they remembered?

There are fourteen themes — seven light and seven dark, including GitHub, Vue, Notion, Newsprint, Solarized, Academic, Nord, Dracula, One Dark, Tokyo Night, and a warm DevKitLab default. Your selection is saved in the browser for next time.

Where is my document saved?

Your draft is stored locally in this browser through localStorage. It is not uploaded, synced, or shared, so copy the Markdown or export a .md file if you need it elsewhere or as a backup.

Can I get the raw Markdown out?

Yes. Use Copy Markdown to put the source on your clipboard, or Download to save a .md file. The output is standard Markdown that other editors and renderers understand.

Does it support tables and task lists?

Yes. Tables, task lists (checkboxes), strikethrough, and other GitHub-style extensions are supported alongside standard CommonMark, and you can insert a table from the slash block menu.

Does my content get uploaded anywhere?

No. Editing, theming, math rendering, copy, and export all run in your browser tab. Nothing is sent to a server, so it is safe for private notes and unpublished drafts.
