About Gender Predictor
Gender Predictor is a free, privacy-first website that lets you play with every popular baby gender prediction method in one place — and, more importantly, tells you honestly which of them have any real evidence behind them.
In one line
We combine nine traditional and modern gender guesses into one fun result, then keep it honest: the medical tests are labelled as the only reliable ones, and every folklore method is clearly marked as entertainment.
What We Offer
A single predictor that runs the Chinese gender chart, the nub theory, Ramzi theory, skull theory, the heart-rate and symptom myths, the 15-sign old wives’ tales quiz, the baking soda and ring tests, plus your own gut feeling — and blends them into one weighted answer with a confidence read. Alongside it we publish plain-language guides and honest comparisons so you always know what you are looking at.
Our Mission
Gender prediction is a joyful, centuries-old pregnancy ritual, but the internet is full of tools that pretend to be more than they are. We wanted the fun without the false certainty: an honest site that lets you guess, explains the biology, and never lets a coin flip masquerade as a diagnosis. Every child is precious, and the gender is a fun detail — not a decision to plan a life around.
Our Methodology & Editorial Standards
- Consensus over hype. Medical claims follow mainstream, publicly documented guidance on fetal sex determination (NIPT, CVS/amnio, anatomy scan).
- Named sources. Where we cite studies or reference material, we link it and keep quotes attributed.
- Scored transparently. Each method is rated on accuracy, timing, evidence, ease and fun so readers can see why something is labelled entertainment or validated.
- Entertainment is labelled entertainment. Nothing on this site is medical advice; the ~50% methods are described as chance on purpose.
- Kept current. Pages carry a reviewed-on date and we update them when information or the calendar changes.
We are a small editorial team, not a clinic. We do not invent named medical reviewers or credentials we do not have; instead we hold ourselves to sourced, consensus-aligned writing and sign off as the Gender Predictor team.
Privacy by Design
This matters to us. Every calculation runs entirely in your browser — your birth dates, cycle data and quiz answers are never transmitted to a server, sold, or stored. No account, no tracking cookies, nothing to leak. There is a full breakdown in our privacy policy.
