A local-first reader for PDF, Markdown, and HTML documents.
 Shiori is a quiet document workspace for reading, marking up, and shipping documents without turning them into somebody else's cloud data. PDF annotation is the core workflow, and recent builds also support Markdown and HTML viewing with tabs, per-document state, and session restore. ## Highlights - **PDF reading and annotation**: highlights, markup tools, thumbnails, export, and local draft recovery. - **Tabs for documents**: open multiple PDF, Markdown, and HTML files; each tab keeps its own view state and survives relaunch until you close it. - **Markdown and HTML previews**: Markdown front matter is surfaced cleanly, and HTML can run in an isolated sandbox only when you choose to run it. - **Desktop side tools**: keep an embedded browser or terminal next to a PDF, including local shells such as `cc` / Claude Code when they are installed. - **Local-first storage**: documents, annotations, recent files, and preferences stay on your device. - **Desktop and mobile targets**: macOS, Windows, Linux, Android direct install, with iOS / iPadOS and Google Play distribution handled through their stores. ## Screenshots       ## Downloads Installers are published on the [GitHub Releases](https://github.com/Nagi-ovo/shiori-releases/releases) page. | Platform | Recommended package | Update path | | --- | --- | --- | | macOS Apple Silicon | `.dmg` | Signed in-app updater | | macOS Intel | `.dmg` | Signed in-app updater | | Windows | `.msi` | Signed in-app updater | | Linux | `.AppImage`; `.deb` for Debian / Ubuntu | `.AppImage` updater or manual package update | | Android direct install | `.apk` | In-app APK update flow | | Google Play | Coming soon | Google Play | | iOS / iPadOS | Coming soon | App Store / TestFlight | Desktop and Android direct-install builds can update from inside Shiori.
