A macOS command-line "multi-tool" for working with Apple Photos. Allows you to export photos (along with all the metadata), batch-edit metadata such as times and timezones, explore the AI metadata Apple computes for each photo (but doesn't make available to the user) such as "well timed shot", "pleasant composition", etc, compare libraries, sync metadata between libraries, and much more! It's written in python and provides a full python API for interacting with Photos.
