Hi Nora,
Ribbet Fly is an advanced Photoshop-like editor which we have built on top of the popular online editor Photopea. It’s a more complex photo editing tool for those users who are familiar with Photoshop, or who would like to try some more complex tasks.
You can actually launch Ribbet Fly from inside Ribbet’s regular editor, by heading to the Pro tab > Pro Editor tool.
Photopea has a manual available here. You can also find various tutorials on YouTube for it.
If you have any further questions please let us know!
