Localization without release friction
Phrase Strings lets design, development, and localization run in parallel.
Phrase Strings is a string management platform that connects product copy from code repositories and design tools to translation workflows, keeping text and translations aligned as teams iterate. Localization becomes part of day-to-day product development rather than a separate, end-of-cycle task.
This makes it easier to support apps, websites, and games with frequent updates, where copy needs to change and ship independently of design finalization or release schedules.
Built for product localization
Automate to deploy faster
Phrase Strings helps you move faster by automating routine steps in the localization process. Import and export content, create and launch translation jobs, and deliver updates, all from one platform. By running translation alongside development, you can ship multilingual products faster and reduce manual effort.
Centralize localization work
Phrase Strings provides a single source of truth for product copy and translations across teams. Owners can assign work, track progress, and collaborate across regions, while over-the-air updates allow text changes to be delivered without tying them to releases.
Deliver high-quality translations
Contextual editing, Figma previews, and customizable QA checks help teams spot issues before translations are delivered. Placeholders stay intact, terminology stays consistent, and UI constraints are respected, reducing rework and last-minute fixes.
Integrate localization into your stack
Phrase Strings offers a robust API, webhooks, and 50+ integrations to connect localization with the tools you already use. From GitHub and GitLab to design tools like Figma, localization fits naturally into existing workflows.
Machine translation, your way
Phrase Strings connects to Phrase Language AI, giving teams access to 30+ machine translation engines, including LLMs, with intelligent engine selection and automated quality scoring built in.
Teams can also bring their own MT or AI models into Phrase Strings and use them alongside built-in engines, with the same workflows and controls.
Why Phrase Strings?
Built for change
Designed for products where text changes continuously. Localization happens alongside product development, so updates don’t have to wait for finished designs or completed release cycles.
Made for key-based software
Optimized for products that manage text through keys across apps, websites, and games. This approach fits naturally into modern software architectures instead of document-based localization workflows.
Fits how teams work
Connects code, design, and translation with minimal process overhead. Automation and integrations help teams stay aligned as products evolve, without adding coordination complexity.
Mobile Apps
Localize in-app text for mobile applications, with updates delivered over-the-air so copy changes don’t require a new release.
Video games
Integrate localization into your game development cycle, supporting UI, dialogue, and frequent over-the-air updates.
Web apps and websites
Localize UI and dynamic web content as it changes, without interrupting development or release workflows.
Other software products
Support localization for any software using key-based text across frontend and backend systems.
Introducing Phrase Strings
Ways software localization connects to your product
Lyst has now designed a process where Phrase allows us to have the content ready on our sites within 1 minute since the translators add or update their translations. We are saving an average of 48 hours on engineering time, each time we deploy a new feature.
The localization management process is so much more streamlined at Livestorm, which makes it much easier to release new versions and add new locales.
The thing that I have seen with Phrase and Personio’s translation management is specifically the ease with which it allows us to scale to additional languages.
Reliable and secure
The Phrase Localization Platform follows best practices in security, stability and performance. This means we comply with the Principles and Security Statements of ISO 27001, PCI DSS, AWS, CCPA and GDPR. Our infrastructure is one of the most resilient and robust available (zero downtime deployments and a 99.9% uptime), and we work hard to ensure it stays that way.
