Where AI Meets Genetics Science
Our predictions combine cutting-edge AI with real genetic science. Not random face blending - scientifically-informed visualization.
Our Technology Stack
Advanced AI guided by real genetic science
Google Gemini AI
Google Gemini reads the parent photos for facial structure and writes your genetics report in your own language. It never infers your genes from a photo — the probabilities come from the Punnett-square engine, and Gemini only explains them. Your photo is checked on your device first by Apple's Vision framework; the cloud is only called if that passes.
TrueDepth 3D Face Scanning
Devices with Apple's TrueDepth camera — the Face ID sensor on iPhone X and later — capture precise 3D facial structure for depth mapping.
Mendelian Genetics Engine
Real Punnett square calculations for eye color, hair color, and other inheritable traits.
The Confidence Ladder
The confidence figure (60–95 %) reflects how complete your inputs are; it is not an accuracy measurement and is capped at 95 % by design.
Confidence Scoring
Each prediction gets a single computed confidence score: it starts at a 60% base and rises with how much family data you provide, hard-capped at 95%.
Privacy-First Processing
Parent photos are deleted a few hours after your prediction; the prediction itself clears after 48 hours by default (24 hours to 30 days, your choice). Scientific mode uses no photos.
Prediction Modes
Choose the level of detail that's right for you
Scientific Mode
No photos needed | Punnett square genetics | Educational breakdowns | Comprehensive PDF report — 4 credits
Standard Mode
Full trait input | Punnett square calculations | Two babies — dominant and recessive scenarios | Two-sheet PDF report — 8 credits
Premium Mode
Grandparent data input | Up to 95% confidence | Video animation | Two-sheet PDF report with three-generation crosses — 12 credits
How It Works
From your family's traits to a prediction, in three steps
Input Data
Enter each parent's traits — Scientific stops there, with no photo at all. Standard and Premium also take a photo or a TrueDepth scan of each parent, and Premium adds all four grandparents.
Genetic Calculation
Our engine calculates trait probabilities in code with Punnett squares — a two-gene eye-colour model (HERC2 + OCA2), hair colour including MC1R red hair, hair type, a three-gene skin-tone model and simple Mendelian traits — before any image is generated.
AI Visualization
AI generates realistic images guided by genetic calculations - not random blending.
Technology FAQ
Common questions about our prediction technology
Confidence isn't set by the mode — it's one computed score. It starts at a 60% base and rises with the data you give us: any grandparent data, each individual grandparent, childhood hair color, ethnicity and both parent photos each add to it, and it is hard-capped at 95%. Premium reaches that cap because it's the only mode that collects grandparents.
Parent photos are used only to run your prediction and are deleted from our servers a few hours after it finishes — never before the prediction completes, and at least 4 hours after upload. The prediction itself — the report and the generated images — is removed from your account after 48 hours by default; you can choose 24 hours, 7 days or 30 days in Settings. Scientific mode sends no photos at all.
Grandparent data reveals hidden recessive genes. A brown-eyed parent might carry blue eye genes from their parents, which our three-generation analysis can detect.
Scientific mode uses pure Punnett-square genetics with no photos at all — it is text only, and the privacy notice even rewords itself to “Your data stays private.” It costs 4 credits, so the 5 starter credits every new account gets cover it. It is for anyone who prefers privacy, or who wants to explore inheritance from parental traits alone: eye colour, eye shape, hair details, face shape, skin tone, height and ancestry. Blood type is not part of the prediction — a separate free blood-type calculator covers it.
