Auto Localize

Ship your app in every language with AI-powered localization

Multi-format project scanning

Detects and rewrites .xcstrings, XLIFF 1.2/2.0, .xcloc, .strings, .stringsdict, Interface Builder strings, Android strings.xml, Flutter ARB, Java .properties, .NET .resx and JSON files, with Unity and Articulate Rise via XLIFF.

Bring your own AI model

Translate with on-device Apple Intelligence for free, or your own OpenAI, Gemini, LM Studio, Ollama or OpenAI-compatible key. No account and no vendor server hold your strings.

Plural- and placeholder-aware translation

Fills every language's plural forms, swaps out %@, %1$d, {{name}} and HTML tags as protected markers, and verifies them on the way back.

Glossary, tone and translation memory

Enforce fixed terms and a brand voice, and automatically reuse text you already translated so it is never sent to a model twice.
