Free DNA tools

Free tools that work on the raw data file you already have — everything runs locally in your browser, nothing is uploaded.

Pick a tool

• Check your DNA file — drop your export and see provider, format, marker count and warnings — all analyzed on your device.
• rsID lookup — search over 242,000 markers by rsID and see which genes and research traits they are linked to.
• Share cards — draw a shareable card about a fun trait and challenge a friend — you pick every word.
• Compatibility check — does your provider's chip cover the markers our catalog uses? Check the file before you analyze.
• Trait explorer — browse 2,600+ heritable traits with genes and evidence strength, searchable in your browser.

How the tools protect your file

• Everything runs locally in the browser — the file is never uploaded.
• No account, email or payment card required.
• Close the tab and nothing remains — the tools store nothing.
