    description
    Markdown Studio is an all-in-one toolkit for Markdown files in
your browser. Read, edit, and export .md without leaving the tab.

WHAT IT DOES
• Renders Markdown with LaTeX math (KaTeX), syntax-highlighted
  code, GitHub-flavored tables, Pandoc footnotes, and Mermaid
  diagrams. Light/dark themes, collapsible sidebar TOC.
• Split-pane source editor with live preview and scroll sync;
  save edits as a new .md download.
• Saves as PDF — math, diagrams, code, and footnotes paginate
  cleanly.
• Saves as Word (.docx) with EDITABLE EQUATIONS. Math is
  embedded as OMML, not screenshots — open the .docx in Word
  and edit any formula in the equation editor. Tables,
  footnotes, hyperlinks, and lists are native Word elements too.

Most browser-to-Word workflows turn math into flat images you
can only resize. Markdown Studio keeps it as math.

FOR LOCAL FILES
Enable "Allow access to file URLs" at chrome://extensions →
Markdown Studio → Details. Chrome turns this off by default;
http(s) Markdown works without it.

PRIVACY
No data leaves your browser. No analytics, no telemetry, no
cookies. Two per-origin localStorage flags track UI
preferences. Source on GitHub; every dependency is bundled.

PERMISSIONS
Content-script access to .md / .markdown / .mdown URLs only.

LIMITATIONS
• Pages already served as text/html are left alone.
• PlantUML not supported (Mermaid is).
• Same-page anchor links render as plain text in Word export.

    Markdown Viewer with Math turns any .md file into a clean, readable page —
without losing your math equations or your sanity.

WHY THIS EXTENSION
Most Markdown viewers handle headings, lists, and code, but fall apart the
moment you write $E = mc^2$. They either fail to render the math, or they
mangle the math by treating dollar signs inside code blocks as formula
delimiters. This extension was built around solving that problem first.

FEATURES
• LaTeX math, rendered by KaTeX. Supports $...$, $$...$$, \(...\), \[...\].
• Robust formula extraction. Dollar signs inside fenced code blocks (```),
  inline code (`...`), or escaped as \$ are correctly left alone.
• Syntax highlighting via highlight.js with automatic language detection.
• GitHub-flavored Markdown: tables, task lists, strikethrough, autolinks.
• Pandoc-style footnotes: [^id] references render as superscript links plus a collected footnotes section at the end of the document.
• Mermaid diagrams: fenced ```mermaid blocks render to inline SVG (flowcharts, sequence, class, state, pie, gantt, etc.). The diagram theme matches your light/dark mode automatically.
• Collapsible sidebar table of contents, auto-built from your headings.
  Click any item to scroll there smoothly; the current section is highlighted
  as you scroll. Click the « tab to hide the whole sidebar; the state is
  remembered.
• Automatic light / dark theme — follows your system setting.
• Full Unicode and CJK support: rendering and TOC slugs both handle Chinese,
  Japanese, Korean, and other non-Latin scripts correctly.
• Works with local .md files when you enable "Allow access to file URLs"
  on the extension's details page.

PRIVACY
This extension does not collect, transmit, or share any data. All rendering
happens locally in your browser. No analytics, no telemetry, no cookies.
The only thing stored is a single per-origin flag that remembers whether
you've collapsed the table-of-contents sidebar.

OPEN SOURCE
The source code is available on the project's repository. The extension
ships entirely self-contained — every dependency (marked, KaTeX,
highlight.js, DOMPurify) is bundled and runs locally.

REQUESTED PERMISSIONS
Only content-script access to URLs ending in .md, .markdown, or .mdown
(both http(s) and file://). The extension does not request access to
your tabs, browsing history, or any other site.

KNOWN LIMITATIONS
• The extension does not try to render markdown when the server already
  returns text/html — it leaves pre-rendered pages alone.
• PlantUML is not supported (Mermaid and Pandoc-style footnotes are).
• Image references using relative paths next to the .md file may not load
  on http(s); local file:// paths work fine.
