Runs on your Mac · your DNA never gets uploaded

The operating manual for your body.

Gramp turns your DNA into a personal operating manual — what you're made of, how you should eat, train and live, and ongoing health monitoring. Analyzed by the model you choose, including local open-weight models, and encrypted on your device.

§ 01What Gramp does

Your DNA, turned into instructions you can act on.

Import from 23andMe, AncestryDNA, MyHeritage or a VCF. Gramp parses it, encrypts it, and turns hundreds of thousands of variants into a clear picture of who you are — and how to work with it.

01🧭

Your operating instructions

Traits translated into what they mean for daily life — how you metabolize caffeine and alcohol, where you lean power vs endurance, what to eat more (and less) of, and what to flag with a doctor.

02🧠

Any model — even fully local

Bring your own AI: Anthropic, OpenAI, or an open-weight model running locally via Ollama. You pick who analyzes you — and with a local model, nothing leaves the machine at all.

03📈

Ongoing health monitoring

Import Apple Health for 30-day trends, and let Gramp watch the literature — daily or weekly — for new studies on your exact variants. Get a report when something relevant lands.

04🔬

See what's changed

Gramp keeps scanning PubMed, preprints, and government clinical-trial registries for the latest on your variants and conditions, then tells you how it changes what a marker means. Only public rsIDs are queried, never your genotype.

05📄

Records & prescriptions → routine

Import lab results, doctor's notes, and prescriptions. Gramp reads them locally, connects them to your genetics, and helps you adjust diet, timing, supplements, and what to raise with your clinician.

06🔎

Every variant, one click

Search 600k+ genotyped positions by rsID or locus, and research any single one against the literature on demand.

§ 02Method

From raw data to a life that fits you.

Four steps. Everything is parsed, encrypted, and kept on your device.

01

Upload your DNA

Bring your raw file from 23andMe, AncestryDNA, MyHeritage — or a VCF. Gramp parses and encrypts it on your Mac.

02

Share your medical records

Drop in a folder of blood tests, diagnoses, prescriptions, and doctor visits. Read locally, never uploaded.

03

Connect your devices

Add Apple Watch, Apple Health, or any device export so Gramp knows your current, day-to-day state.

04

Live the plan & celebrate wins

Gramp knits your genetics, records, and metrics into the lifestyle you want — and tracks the progress you make.

§ 03The difference
Typical DNA service
  • Upload your genome to their servers
  • A black-box report you can't inspect
  • $199–$299 and their choice of model
  • One report, then it's static
Gramp
  • Runs on your Mac — raw DNA never leaves it
  • Open, inspectable, and yours to export
  • Any model you like, including local open-weight
  • Keeps monitoring as new research lands
§ 04Privacy by architecture

Your raw DNA never leaves your machine.

Genetic data is the most sensitive data there is. Gramp is built so the private parts physically can't leave — not a policy, an architecture.

  • Encrypted at rest.Everything lives in a passphrase-locked, AES-256 (SQLCipher) vault on your device.
  • De-identification boundary.Only public rsIDs and de-identified questions ever reach a model or research API — never your genotypes.
  • Local embeddings.Documents are indexed on-device; your medical text is never sent out for embedding.
  • Fully local option.Point Gramp at a local model and nothing leaves the device at all.
