I came across rewind.ai for macos a year ago and have wanted something like this for windows/linux ever since. As long as this is all processed on-device as promised, I’m super excited and it might actually be enough to get me to upgrade from Windows 10 to 11. Except I think it requires an NPU which afaik my ~epic gamer pc~ doesn’t have, so maybe in the future.
Available information indicates that it’s all processed and stored on-device (and even encrypted). I’ll wait for confirmation from security researchers, but the available information I’ve come across says that it’s all done locally.
