Xpolyglot by FiveSheep
A macOS app for translating Xcode string catalogs and App Store listing content with a separate OpenAI API key.
About Xpolyglot by FiveSheep
Xpolyglot is a macOS localization app built for developers working with Xcode projects. It imports Xcode projects, keeps localization work organized, and uses an OpenAI API key to translate string catalogs. Delta updates identify changed strings so teams can translate only what needs attention, which can reduce repeat API usage. The app also supports App Store Connect listing content, including descriptions and keywords, and helps translate the “What’s New” text for new app versions. Length and relevance checks help developers prepare localized store listing content. Xpolyglot is notarized by Apple. It is sold as a $9.99 one-time purchase with lifetime free updates, while OpenAI API usage is a separate cost. This combination makes it most relevant to Mac-based Apple-platform developers who want an Xcode-centered workflow and are comfortable supplying and paying for their own OpenAI API key.

Pros
- Xcode project import keeps localization work close to the existing Apple development workflow.
- Delta updates can reduce repeated translation work and related OpenAI API usage by targeting changed strings.
- The $9.99 one-time purchase includes lifetime free app updates, avoiding a recurring app subscription.
Cons
- Translations require a separately configured OpenAI API key, adding setup work and variable usage charges.
- The app requires macOS and is centered on Xcode projects, so it does not fit non-Apple development workflows.
- AI-generated translations may still need human review before release when wording, brand voice, or market nuance matters.
