What you'll get
Polygenic risk scores
11 health categories analysed against the GWAS Catalog: diabetes, cardiovascular, Alzheimer's, cancer, and more.
Pharmacogenomics
See how your genetics may affect response to common medications like warfarin, metformin, or SSRIs.
AI-powered explanations
Plain-language explanations of your results, grounded in peer-reviewed research from PubMed.
SNP search
Look up any variant by rsID and see your genotype, population frequency, and associated traits.
What your raw data doesn't tell you
Your DNA file is just letters until someone reads it against the research.

… 600,000 more linesYour raw DNA file
Around 600,000 lines of rsIDs and A/C/G/T. Technically your genome — practically unreadable.
One copy of the T risk allele — associated with ~37% higher relative risk of type 2 diabetes.
Your report
The same data cross-referenced against 78,000 GWAS associations, scored, and explained in plain language.
Your DNA, your data
We take privacy seriously. Your DNA is stored on our EU server and used only to generate your report — we never sell it or share it with insurers, researchers, or marketers. For AI explanations, risk scores and variant identifiers (not raw DNA) are sent to Anthropic (Claude). You can delete everything at any time.
Calibration & limits
We're upfront about what these numbers can and can't tell you. Accuracy depends on how many relevant variants your file covers and on your ancestry — and nothing here is a medical diagnosis.

Frequently asked questions
Is this a medical diagnosis? ▼
No. This is a research-based informational tool using published GWAS studies. It's not a diagnosis and should never replace advice from a qualified healthcare professional.
How accurate are the results? ▼
Accuracy depends on chip coverage (how many relevant variants your DNA file contains) and population bias in the underlying studies (mostly European ancestry). Each result shows a confidence level so you know how reliable it is.
Can I delete my data? ▼
Yes. Any uploaded analysis can be deleted from the history page. You can also delete your entire account from settings — this removes all SNPs, scores, and personal data permanently.
Do you share my DNA with anyone? ▼
No. Your data is used only to generate your report. We don't share, sell, or license it to research institutions, insurers, or any third party.
Which DNA providers are supported? ▼
23andMe (.txt), AncestryDNA (.txt), and MyHeritage (.csv). You need the raw DNA data file — not the health/ancestry PDF reports.
Is it free? ▼
The core analysis is free. AI-powered explanations use Claude (Anthropic) and are rate-limited per user to keep the service sustainable. You can always read the full variant breakdown without using AI.
What if I'm not of European ancestry? ▼
Be cautious with the numbers. The GWAS studies behind these scores have historically over-represented people of European descent, so predictive accuracy is measurably lower for African, East Asian, South Asian, Hispanic/Latino, and other ancestries. The platform surfaces this on every report with a prominent banner. The underlying rsID associations are still informative, but the relative-risk estimates are calibrated on a population that may not match yours. Use the results as a starting point for conversation with a clinician, not as a definitive answer.
