- Apple Live Text (VisionKit framework): this will work on macOS Ventura or later. It should be the same as Vision except that in Sonoma Apple added vertical text reading, on the other hand it's a bit slower/requires a small Swift helper tool to be downloaded (source code is in this repo, it's a stripped down version of LiTeX). ("d" key)
- WinRT OCR: this will work on Windows 10 or later if winocr (`pip install winocr`) is installed. It can also be used by installing winocr on a Windows virtual machine and running the server (`winocr_serve`), installing requests (`pip install requests`) and specifying the IP address of the Windows VM/machine in the config file (see below) ("w" key)
