Prevyu: AI Fitness Visualizer

What if you could see yourself at the finish line before you take the first step?

Prevyu uses AI to show you what you could realistically look like after reaching your fitness goal. Not a filter. Not a fantasy. A personalized, science-informed preview of the body you're working toward.

How it works:
Upload a photo of yourself, enter some basic info — height, weight, body type — and tell us your goal. Lose 30 pounds. Build muscle. Tone up. Prevyu combines your data with AI image generation to create a realistic visualization of your transformation. Your face, your body, your goal — just further down the road.

Built on real fitness science, not gimmicks.

Other apps slap a filter on your photo or let you drag a slider until you look like a superhero. Prevyu is different. Your transformation is grounded in your actual body data and what's achievable naturally. We cap results at healthy ranges, flag unrealistic goals, and never generate imagery that promotes unhealthy body standards.

What makes Prevyu different:
* Your photo + your real biometric data = a result that's actually about you
* Health guardrails prevent underweight, unhealthy, or unrealistic output
* Goal-based, not filter-based — describe where you want to go, not how you want to look
* Side-by-side comparison so you can see the potential change
* Persistent disclaimers because we want to motivate you, not mislead you

Set a goal:
— Lose weight: enter a target weight or pounds to lose
— Gain muscle: general or targeted (arms, chest, legs)
— Body recomposition: lose fat and gain muscle simultaneously
— Tone and define: moderate fat loss with muscle definition

Get the best results:
Prevyu guides you through taking the right kind of photo — good lighting, front-facing, form-fitting clothing — so the AI has what it needs to create a high-quality result.

Free to try.
Your first transformation is free. Want more? Credit packs start at $2.99, or upgrade to Prevyu Pro and get a generous monthly quota for generating transformations.

Your privacy matters.
Your photos are yours. We don't use them to train AI models. We don't build facial recognition databases. Biometric data is encrypted. You can delete everything at any time.

This app generates AI illustrations meant to inspire — not predict. Real results depend on genetics, nutrition, training, and many other factors. Always consult a healthcare or fitness professional before starting any program.
