Frequently Asked Questions

Does the AI muscle filter keep my face?

Yes. Your face, clothes and background stay the same; only your build changes, growing into a bodybuilder physique.

What photo works best for the muscle filter?

A photo that shows your upper body, standing or sitting upright, in fitted or regular clothes.

Can I post the muscle-up video as a joke?

That is what most people do. The 4-second vertical clip is sized for Reels, TikTok and Shorts.

What does an effect cost?

New accounts get free credits that cover one effect. One more effect costs one small credit pack, and failed runs are refunded.
