Marksist

A markdown editor for the AI age.

Beta
Opportunity

Most markdown editors are either too simple, lacking features writers need, or too complex, trying to be second brains like Notion or Obsidian. Writers need a focused, elegant tool for writing and previewing Markdown with zero friction, a beautiful UI, and optional AI assistance that can directly edit their documents.

Product
  • Three Views, Switch seamlessly between Markdown-only, Split (editor + preview), and Render-only views
  • AI-Powered Editing, An AI assistant that doesn't just suggest, it can directly edit your document with diff highlighting
  • Beautiful Syntax Highlighting, Color-coded Markdown tokens for maximum readability
  • GitHub Flavored Markdown, Full GFM support including tables, task lists, strikethrough, and code block highlighting
  • Math Support, LaTeX math rendering via KaTeX
  • Dark & Light Modes, Both themes fully designed, respects system preference
  • Tab System, Open multiple files with instant switching and session restore
  • No Lock-in, Files are just .md files on disk. No proprietary format, no database, no sync service
