Lingo.dev is a localization engineering platform designed to integrate translation workflows into a software product's infrastructure. It uses a stateful engine that remembers glossaries, brand voice, and model configurations across requests, which may help maintain consistency in how a product is translated across various languages.
The tool is intended for developers, product teams, and enterprise localization managers. It handles the process from source refinement and AI translation to quality scoring and delivery via webhooks or WebSockets.
One practical aspect of the platform is its ability to route translations to certified human reviewers when AI quality scores fall below a user-defined threshold. This supports the management of high-visibility or regulated content without requiring separate vendor management for every project.
Buyers should confirm how the token-based pricing aligns with their expected volume and whether the API-first approach fits their existing CI/CD pipeline.
Key Features
Remembers glossary, brand voice, and model configurations across requests to support consistency.
Uses an LLM to pre-process source text, resolve ambiguous references, and flag placeholder issues before translation.
Provides access to a network of certified translators to review LLM output based on configurable quality triggers.
Uses a second, independent model to score translations for fluency, accuracy, and style.
Matches source terms to glossary entries using vector embeddings and applies locale-specific brand voice profiles.
Supports isolated context and token consumption tracking per user, project, or product.
Use Cases
Translating product content via HTTP with options for synchronous and asynchronous delivery.
Using GitHub Actions to trigger translations on every push, which adds localized strings to pull requests.
Locking specific terminology and tone across multiple languages to help ensure a consistent product identity.
Setting quality thresholds that route low-scoring translations to human reviewers.

FAQ
It is a translation API that remembers your glossary, brand voice, and model configuration across multiple requests to help maintain consistency.
It uses a cross-model evaluation where one model translates and another scores the result. If the score falls below a set threshold, the text can be routed to certified human translators.
There is a free Sandbox available and a Production Base plan for $99/month. Infrastructure usage starts at $2 per million tokens, while LLM costs are passed through without markup.
