You can add a filter or lens to your Snaps, but the process is quite different, depending on the effect you want to use.
You can reverse a video on Snapchat by using a filter that's always available and built into the Snapchat app.
The Imagine Lens lets users transform their Snaps or create entirely new images by simply entering a text prompt.
Snapchat is making its once paid Imagine Lens feature free which lets you create AI filters for Snaps free for everyone.
