Open on GitHubWhat DialectOS does
The server adapts technical content for 25 regional Spanish variants, such as Mexican and Argentinian. It includes 17 MCP tools. The tooling catches semantic drift while keeping markdown tables and code blocks intact. It also handles JSON locale file validation and merges.
Running the tool requires Node 20.0.0 or higher and pnpm 11.12.0. The 0.3.0 package is published as a GitHub release tarball instead of an npm registry package. Without a valid LLM_API_URL endpoint and an assigned LLM_MODEL, translation tools will not execute.
DialectOS checks formality levels between "tú" and "usted" across target regions. It supports gender-neutral options like "elles" and words ending in "-x". Quality checks rely on a public test suite of 205 adversarial samples covering regional nuances.
What it helps with
- translate markdown documentation into Mexican or Argentine Spanish without altering code blocks
- validate i18n JSON locale files against regional vocabulary and grammar drift
- enforce consistent "tú" versus "usted" formality across target locales
- apply terminology glossaries to Spanish translations
