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.
Files and edits are saved in this browser for offline use. Download a copy to keep it outside the browser; clearing site data removes the workspace. Opening a file does not change the original on disk.
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.
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.
