Copy once, paste anywhere - instantly across devices
Multi-device users waste 10+ minutes daily trying to transfer text/images between phone and computer using clunky email, cloud apps or incompatible tools
EchoClip creates a universal, real-time synced clipboard that works seamlessly between your smartphone and computer. Copy text, images or files on one device and they appear instantly on all others. It runs in the background with a browser extension on desktop and a PWA on mobile, eliminating the need for email, cloud drives or incompatible tools.
Professionals and students who actively use both smartphone and computer throughout the day (remote workers, developers, researchers, content creators)
True OS-level clipboard integration with persistent WebSocket connections optimized for battery life, combined with end-to-end encryption so the company never sees your content - unlike bloated competitors that route everything through their servers.
