Stronger: AI Muscle Filter

Upload a photo and see how another body would look on you. Stronger uses generative AI
to hand your own photo back with more mass, sharper definition or a more athletic build — and
lets you compare before and after by dragging across the same image.

NINE LOOKS, ONE TAP
Bulk, Cut and Athletic, each in three levels — more muscle, a visible six pack, or
a leaner gym body. All of them sit on the same screen: pick one
and the image is generated right there, without switching screens or filling in forms.
Not convinced? Tap another one.

BEFORE AND AFTER, ON THE SAME PHOTO
The slider runs across the image under your finger, so you see exactly what the muscle
editor changed: the muscle goes on below the neck only, and your face and pose stay
put. Bulk fills out the shoulders, Cut brings out the abs. No collages, no frames: the same
photo, split wherever you want it.

YOUR RESULTS, ON YOUR PHONE
The app keeps your last 30 results in its own gallery, on the phone itself, and you can
reopen any of them in the comparator whenever you like; once you reach 30, the oldest
one makes room for the new one. You can delete them all at once from Settings.

WHAT WE DO WITH YOUR PHOTO, NO SMALL PRINT
Your photo leaves your phone encrypted, goes through an automatic safety check at
Google, then to our AI provider to generate the result, and the result goes through
that same check again, and is never stored on
Stronger's servers. Before your first upload we tell you
exactly who processes the image and under whose policies. No accounts, no sign-up, no
ads.

EVERY RESULT IS MARKED AS AI
Because EU law requires it and because it is the honest thing to do: every result carries
technical image-generation marking that any tool can check. And there is a report button
right on the result screen.

Results
are AI-generated images for entertainment: they predict no real physical change,
and the app gives no medical, fitness or nutrition advice.
