Questions

Does anything I bring in leave my computer?

No. DockJack does all of its work on your computer. It only reads public things in, like daily currency rates, and downloads a model only when you choose to install it. Each connection is listed in Settings, and Work offline turns them all off.

Does it use AI?

DockJack doesn't need AI. For a few tools, you can run an AI model on your own computer with one click: transcripts, translation and background removal.

Which computers does it run on?

Mac: macOS 13 Ventura or later, on Apple silicon (M1 or newer). Windows: Windows 10 or 11, 64-bit. It installs just for you, so no admin rights are needed. Under 50 MB to download. Optional tools and models you install take more.

Is it a clipboard manager?

No. It works out what you have, however it arrived, and does the job you would otherwise take to a website.
