Codon
For the 15M people who just left 23andMe

Stop reading 20,000 cryptic SNP rows. Talk to your genome instead.

Codon parses the raw DNA file you already downloaded — 100% in your browser — then lets an AI genetic counselor answer anything about your traits, drug interactions, and carrier status. The file never leaves your device.

A real Codon conversation
I'm about to be prescribed clopidogrel — does my CYP2C19 matter?
You carry *2/*1 — that makes you an intermediate metabolizer. Clopidogrel (Plavix) is a pro-drug your CYP2C19 enzyme has to switch on, and intermediate metabolizers get a weaker antiplatelet effect. The FDA label carries a boxed warning about exactly this. Worth showing your cardiologist — alternatives like prasugrel or ticagrelor aren't CYP2C19-dependent.Read from your rs4244285 (G;A) · rs4986893 (G;G)

Every answer is grounded in your actual genotype and shows the SNPs it read.

Conversational, not a wall of rows

Promethease hands you 20,000 rows of magnitude/repute columns. Codon answers the actual question you have, in plain English, about your specific genotype.

Local-only by architecture

The raw file is read with the browser's FileReader and parsed in memory. Only a tiny, question-relevant slice of variants is ever sent to the AI — never the genome.

Grounded, hedged, auditable

The counselor reasons only over curated ClinVar / PharmGKB / SNPedia evidence, distinguishes association from destiny, and shows you the SNPs behind every claim.

Ask your DNA anything

The model maps your fuzzy question to the right loci, reads them out of your file, recalls the literature, and translates it — work a static report structurally cannot do.

You already have the file. You just don't trust where it lived.

23andMe's bankruptcy taught 15 million people that a genome is a corporate asset that gets sold in a liquidation. You deleted your account — but kept the genome_v5.txt in your Downloads. Codon is the place to ask “what does this actually mean for me?” without re-trusting anyone with your DNA.

Important. Codon is an educational tool that helps you interpret raw genetic data you already own. It is not a medical device and does not diagnose, treat, or prevent any condition. Genetic associations describe probabilities across populations, not your destiny. Always talk to a qualified clinician or genetic counselor before making any health decision.
