Enterprises pay a coordination tax on localization

Managing shared glossaries, aligning terminology across teams, and carrying the cost of ever migrating. An organization-scoped localization engine with retrieval at inference time, and forward-deployed localization engineering from the Lingo.dev team, reduce the tax.

The Localization API

Professional localization - source refinement, glossary enrichment, quality scoring, and optional human review - encapsulated behind a single POST. One request, any number of target locales, results via webhook.

Introducing Lingo.dev v1.0

After proving that retrieval augmented localization reduces LLM terminology errors 17-45%, we built Lingo.dev v1.0 - a localization engineering platform where teams create stateful localization engines with per-locale models, glossaries, and quality scoring.

Retrieval Augmented Localization Cuts LLM Terminology Errors 17-45%

Raw LLMs translating isolated paragraphs produce 17-45% more terminology errors without a domain glossary. Holistic quality metrics miss this entirely.
