Phrase

Phrase is an AI-powered localization and translation platform designed to help enterprises, product teams, and language service providers manage multilingual content at scale. Built around a unified Phrase Localization Suite, the platform combines a translation management system (TMS), computer-assisted translation (CAT) editor, AI-driven machine translation orchestration, terminology management, and quality assurance tooling into a single ecosystem. Its core promise is to accelerate time-to-market for multilingual products by automating repetitive translation tasks while maintaining human-level quality where it matters most.

Phrase serves over 500 enterprise customers across 50+ countries, processing more than 100 million words per month through its platform. Companies including Shopify, Uber, Decathlon, Puma, and Buffer rely on Phrase to localize their applications, websites, and marketing content into dozens of languages. The platform supports over 500 file formats and integrates with 50+ tools across the development, design, and content management ecosystem, making it one of the most broadly connected localization platforms available.

The platform is architected around two complementary products. Phrase Strings handles software and app localization with developer-centric features like Git integration, CLI tooling, branching of translation keys, and over-the-air (OTA) mobile SDKs that push translation updates to iOS and Android apps without requiring app store resubmission. Phrase TMS manages enterprise content and document translation workflows with linguist and vendor management, project automation, and quality assurance checks. Both products share a common translation memory, terminology management layer, and AI orchestration engine called Phrase Language AI.

Phrase Language AI is the platform's differentiating technology layer. It automatically selects the best-performing machine translation engine for each language pair and content type from providers including DeepL, Google, Amazon, and Microsoft, then applies glossary enforcement, formatting preservation, and quality estimation scoring. The Quality Performance Score (QPS) predicts translation quality per segment, enabling teams to auto-publish high-confidence machine translations and route only lower-confidence segments to human linguists — reducing costs by up to 90% on suitable content types while maintaining quality thresholds.

For development teams, Phrase offers a comprehensive API-first architecture with a REST API, CLI, webhooks, and native integrations with GitHub, GitLab, Bitbucket, Azure DevOps, Jenkins, and CI/CD pipelines. Design teams benefit from plugins for Figma, Sketch, and Adobe XD that enable in-context translation directly from design files. Content teams connect through integrations with WordPress, Contentful, Drupal, and Adobe Experience Manager. This breadth of integration ensures localization can be embedded into existing workflows rather than requiring teams to adopt entirely new processes.

Phrase holds ISO 27001 and SOC 2 Type II certifications, is fully GDPR-compliant, and offers regional data hosting in the EU and US. It supports SSO, SAML, MFA, role-based access controls, and audit logging, making it suitable for regulated industries including automotive, financial services, and healthcare. Founded in 2014 in Hamburg, Germany (originally as PhraseApp), the company has grown to 200-500 employees and serves as a strategic localization partner for organizations scaling their global presence.
