gnomancer keeps DNA analysis on your own machine
An open-source command-line tool that turns consumer DNA exports or VCF files into local HTML, Markdown, TSV, and JSON reports.
- For
- People analyzing consumer DNA exports locally
- Worth noticing
- ClinVar hits are scored for plausibility; the site warns that rare consumer-array calls can be unreliable.
Field notes
The workflow accepts ZIP exports from named consumer vendors, plus VCF, detects vendor and genome build, and remaps older builds to GRCh37. It installs open-source tools and reference data once, then produces a searchable, printable report with technical detail below its summary. The site says there is no account, upload, telemetry, cookies, or analytics; optional AI summaries send structured result tables—not the raw genotype file—to Anthropic. The displayed example uses synthetic data.
