A SelfDecode alternative without the subscription.
SelfDecode is a big health platform: a large report library, polygenic scores, and ongoing recommendations under a subscription. Helisoma is deliberately smaller: one honest wellness report, bought once, parsed in your browser, and readable by the AI assistant you already use.
What SelfDecode does well
Breadth and ambition. SelfDecode offers one of the largest consumer report libraries, uses polygenic scores that combine many variants, and keeps shipping new health content. If you want an all-in subscription health platform, it is a serious product.
Where Helisoma is different
| SelfDecode | Helisoma | |
|---|---|---|
| Your raw DNA file | Uploaded to their servers for processing | Read in your browser, never uploaded |
| Pricing | Subscription plans | $49 once, free analysis first, no subscription |
| Findings style | Large report library with in-platform recommendations | A curated set of replicated findings, each stating its effect size honestly |
| Works with your AI | No pairing with outside assistants | Connects to Claude live, pairs with ChatGPT, Gemini, and Whoop Coach |
| Where advice lives | Inside their platform | In your own AI chat, grounded in your report |
Which one should you pick?
Pick SelfDecode if you want an all-in-one subscription platform with a large report library and in-platform recommendations refreshed over time.
Pick Helisoma if you want to pay once, keep your raw file on your own device, and get coaching through the AI you already talk to every day instead of another app.

Questions people ask
Do I have to upload my raw DNA file to Helisoma?
No, and that is the core difference. Your browser reads the file on your own device and sends only the small set of markers the report uses. We never receive or store the raw file.
What does the Helisoma report cover?
Sleep and chronotype, caffeine response, nutrition markers, training and recovery, stress and mood leans, and longevity markers. Every card shows your genotype, the honest effect size, and a link to the study behind it.
How much does Helisoma cost?
The analysis is free: drop your raw DNA file on helisoma.com and see real insights with no account. The full report is a one-time $49 payment with no subscription.
Is Helisoma a medical test?
No. It is an educational wellness report built on peer-reviewed population research, not a diagnosis. Clinical questions belong with a doctor.
