Nashi is an independent, open-source file conversion and editing app inspired by Tangerine's drag-and-wheel interaction. It adds public web-media downloads, QR reading, refined crop/annotation workflows, keyboard media editing, live progress and signed automatic updates. Nashi is not affiliated with Tangerine or LEAP STUDIO and includes no proprietary reference-app binaries or artwork.

Try the interactive browser playground: drag sample files, use the wheel and shortcuts, and explore all 27 tools. Supported image/PDF/audio exports are real; desktop-only operations are labeled previews.

A real macOS 0.7.3 screen recording: drag files in Finder, use the wheel to convert to JPG, crop an image and trim a video with In/Out handles. Pauses and longer previews are shortened; retained actions play at normal speed. English and Turkish captions are available in the video player.

Download and use

• macOS ZIP · Apple Silicon, macOS 13+: extract, move Nashi.app to your Applications folder and open it. The full macOS catalog has 27 tools, 45 input formats and 275 conversion routes.
• Windows x64 ZIP: extract the entire archive into its own writable folder, then open Nashi.exe. No separate .NET install is required. Keep the folder together so portable updates can replace the app safely. Windows features and differences.

These first public builds do not have Apple notarization or Windows Authenticode publisher signing. Your OS may require first-launch approval; consult Apple's guidance. Nashi does not disable system security settings. Official release assets include SHA-256 checksums. A CI artifact alone is not an official signed update.

Shortcuts

On macOS, hold Shift while dragging in Finder for conversion, Command for tools or Control for file actions. Control–Shift–D downloads a copied public link. Drag modifiers are customizable. On Windows, use Ctrl+O to choose files, Ctrl+V to import copied files/text/images, and Ctrl+Space for the tools wheel. Ctrl+2 opens Library; Ctrl+F searches it. Normal paste inside text fields is preserved. Home and Library share the Mac color palette, rounded cards and gold actions, with System/Light/Dark appearance.

Supported media editors use Space for play/pause, Left/Right to seek one second and I/O to mark a range. Crop uses drag, Shift for aspect lock and Enter to save. The English and Turkish pages contain the complete macOS shortcut sheet; the Windows guide lists its available controls.

Privacy and updates

Conversion/editing run locally. Web downloads contact the selected media site. No analytics, cloud account or browser-cookie import is built in. Official releases update through this public repository without a GitHub account or token. macOS verifies the signed feed and archive; Windows verifies the archive signature and version before replacement. Active operations finish or cancel before the app exits for an update. Portable Windows updates retain the previous folder as a recoverable backup.
