[OS] ClipFlow: A local-first clipboard manager with offline AI and private cross-device sync
I built ClipFlow originally for myself because I wanted a clipboard manager that could do a bit more than just keep a history — without sending everything I copy to some server.
It keeps clipboard history locally and handles text, links, code, files and images. There’s also on-device OCR, so I can copy an image or screenshot and pull the text out of it directly.
The part I’ve been experimenting with recently is local AI. It can summarize, rewrite, translate, explain or answer questions about copied content, with the goal of keeping the processing on-device rather than sending clipboard data to an external AI API.
I’m also working on encrypted cross-device sync between macOS, Windows, Android and iOS. Instead of using S3 or storing everyone's clipboard history on my server, devices communicate directly and only paired devices can exchange clipboard data.
So the general idea is pretty simple: clipboard history + OCR + local AI + private device-to-device sync, while keeping as much as possible on your own devices.
It’s still very much a personal project and there are rough edges, but it has become useful enough for me that I figured other people here might enjoy playing with it too.

Would love to hear what you think, especially what you’d want from the AI/sync side of a clipboard manager.
