Calabi Sanitizer vs remove-ai-watermarks

remove-ai-watermarks is the closest direct competitor — a Python CLI that handles C2PA and EXIF stripping. But it stops at stripping. Calabi also injects authentic phone identity.

When to choose Calabi instead

• You work with video (MP4 / MOV / WEBM), not just images.
• You want the file to look like a real phone capture after cleaning — Make / Model / GPS / timestamp injected.

• You don't want to install anything or run a GPU.
• You want to batch upload multiple files from a web UI.
