Built like a product, focused like a motivation tool
The experience is designed to reduce friction and make the visual goal feel personal, simple, and easy to revisit.
Three-frame comparison
See current, -7 kg, and -15 kg together instead of guessing what progress might look like.
Photo-based preview
The result is designed around your uploaded image, pose, and face rather than a generic body chart.
Motivation first
Use the preview as a visual reminder for habits, workouts, nutrition, and consistency.
No account wall
The first experience should feel fast and easy: upload, preview, compare.
Get the best results
A few simple choices make the three-frame preview feel more believable and easier to compare.
Wear fitted clothing
Avoid oversized layers so body shape is easier to read.
Use bright natural light
Clean lighting makes the preview feel more realistic.
Face the camera
Stand straight with your torso and face visible.

Upload one photo and compare three versions of yourself.
Questions before you try it
A realistic preview is useful when expectations are clear from the start.
What kind of photo works best?
Use a clear, front-facing photo with good lighting and your full torso visible. Avoid heavy filters, extreme angles, and baggy clothing.
Is this a medical or fitness prediction?
No. It is a visual simulation for motivation and curiosity. Real results depend on your body, habits, health, and timeline.
Will the preview look exactly like future weight loss?
No AI preview can guarantee that. The goal is to make a possible transformation easier to imagine, not to promise a precise outcome.
Does it change the face too?
The examples show both body-focused and face-aware previews, including subtler cheeks, neckline, and jawline changes when the photo supports it.
