crosspaste/crosspaste-desktop — reverse-engineered prompt

Build me a desktop app called CrossPaste that lets me copy something on one device and paste it on another device on the same local network. It should work on Mac, Windows, and Linux with a clean consistent interface.

I want it to keep a clipboard history and support common things people copy, like text, links, colors, rich text, HTML, images, and files. It should sync quickly between trusted devices, store data locally, and protect clipboard content with encryption so it isn’t sent through a cloud server. Add simple device pairing, search, and settings for automatic cleanup so old clipboard items don’t take over storage.

Please include local OCR so text can be extracted from screenshots without uploading them anywhere. Also include a Chrome extension that can connect to the desktop app and join the same clipboard sync. If reasonable, add an MCP option so AI assistants can access clipboard history when the user turns it on.

Look up current docs online if you need to.
