Paperling

Paperling is a no-setup Markdown reader and editor. You open any .md file, read it rendered nicely, and edit with a live preview in which math, chemistry and diagrams render as you type. An optional AI, free and bring-your-own-model, proposes edits that you accept or reject inline, with no vaults or plugins to configure.

The author built it out of frustration with seeing raw Markdown in basic text editors, and positions it as lighter than tools such as Obsidian when you only want to open a file and edit it. Rendering supports KaTeX math and Mermaid diagrams, there are four themes called Dark, Light, Paper and Dracula, and the interface includes a file explorer and command palette. A small paper character appears in the app to greet and guide new users.

Paperling is built with Tauri, React, TypeScript and Rust for desktop on multiple platforms, with an Android APK available from the releases page. It is licensed under Apache-2.0 and runs locally on your device.
