Kaho Clipboard - E2EE Real-Time Sync

Zero-Knowledge End-to-End Encrypted Cross-Platform Clipboard Synchronization for Web Browsers.

Kaho Clipboard keeps your copied text in sync across all your devices — Windows, Linux, macOS, Android, and your browser — in real time, with end-to-end encryption. When you copy text on one device, Kaho automatically and securely delivers it to your other paired devices, so it's ready to paste wherever you need it next. All clipboard content is encrypted (AES-256-GCM) on your device before it ever leaves — the relay server only ever sees ciphertext and cannot read your clipboard contents. Getting started takes seconds: pick a room name and passphrase (or sign in with a sync code / email and password), then use the same credentials on your other devices. No account is required for room/passphrase mode. Features: • Real-time, two-way clipboard sync across desktop, mobile, and browser • Zero-knowledge end-to-end encryption — the server never sees your plaintext clipboard • Works with room+passphrase, sync code, or email/password pairing • Desktop notification when new clipboard content arrives from another device • Right-click menu for quick sync actions
