How AI is used
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
Stateful Localization Engines
Remembers glossary, brand voice, and model configurations across requests to support consistency.
Source Refinement
Uses an LLM to pre-process source text, resolve ambiguous references, and flag placeholder issues before translation.
Human Post-Editing
Provides access to a network of certified translators to review LLM output based on configurable quality triggers.
Automated Quality Scoring
Uses a second, independent model to score translations for fluency, accuracy, and style.
Context Enrichment
Matches source terms to glossary entries using vector embeddings and applies locale-specific brand voice profiles.
Multi-Tenant Infrastructure
Supports isolated context and token consumption tracking per user, project, or product.
Use Cases
API-Driven Translation
Translating product content via HTTP with options for synchronous and asynchronous delivery.
CI/CD Localization Integration
Using GitHub Actions to trigger translations on every push, which adds localized strings to pull requests.
Brand Voice Enforcement
Locking specific terminology and tone across multiple languages to help ensure a consistent product identity.
Quality-Gated Workflows
Setting quality thresholds that route low-scoring translations to human reviewers.
Integrations
- GitHub Action
- Lingo CLI
- Lingo React MCP
- Webhook delivery
- WebSocket delivery
