How browser‑based analysis works
- 1. Select your file: Choose the raw export from your provider.
- 2. Parse & normalize: The browser parses SNPs and normalizes values for trait scoring.
- 3. Score traits: We map known associations and compute indicators locally.
- 4. Explore results: Browse categories and explanations, all rendered in your session.
Performance tips
- • Use a modern browser (Chromium, Firefox, Safari) for best performance.
- • Close heavy tabs while analyzing very large files.
- • Keep your device on power to avoid throttling.
Compatibility
- • Works with common raw DNA text exports used by major providers.
- • Contact support if you need help converting niche formats.
- • Results are educational and not clinical diagnostics.
Frequently asked questions
Why analyze DNA in the browser?
It avoids uploads, reduces wait times, and keeps sensitive genetic data under your control.
How big can my file be?
Common SNP text exports are typically tens of megabytes and analyze within minutes depending on your device.
Which providers are supported?
We support common raw exports used by major DNA testing services and genealogy tools.
Does this work offline?
Once the page is loaded, parsing and analysis are local. A stable connection is recommended for initial load and updates.
Is this medical testing?
No. Results are for education and curiosity - they are not medical advice.
