The readm3 terminal reader, in your browser. Open a folder or a few files to get started: Markdown renders as a document, any other text file (JSON, code, config, logs) is shown as highlighted, foldable code you can edit, and PDFs and images open in the browser's own viewer.

Edits are kept in this browser as you type, so nothing is lost offline. In Chrome, Edge and the installed app, Open folder and Open files work on the real files: Ctrl / ⌘ S writes your changes back, and a dot marks a file whose disk copy is behind. Other browsers open a copy, and Ctrl / ⌘ S downloads it.

    
Install from your browser’s install menu, or on iPhone and iPad use Share → Add to Home Screen. After your first visit, the reader works offline. URLs need an internet connection and a host that allows browser access.

    

  
  
    
Open a file URL

    
Paste a raw file URL or a GitHub file link: Markdown, JSON, code, a PDF or an image. The file is fetched directly from its host and added to your workspace.
