Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

I18N overview
What is I18N?
I18N is a native macOS desktop application that delivers AI-powered localization for iOS, macOS, Android, and JavaScript projects. Powered by GPT-4, it translates app string files across multiple languages simultaneously, supporting JSON, XML, Localizable.strings, and String Catalog (.xcstrings) file formats. Translation can be scoped at four levels of granularity: a single value, a single key across all languages, an entire language column, or all languages at once. Batch translation across full key-value rows is available in GPT-4 mode for subscribed users. Contextual translation allows developers to describe the usage scenario of the content being translated, producing output tailored to linguistic nuances and cultural considerations.
I18N integrates directly with Xcode, VSCode, and Android Studio, surfacing localization management inside the development environments developers already use. Multi-language string files are loaded and managed within a single interface, keeping translation output in sync without requiring context-switching to external tools or web platforms. The application targets individual developers and development teams responsible for maintaining multi-language string files across mobile and web platforms, reducing the manual effort associated with managing localization at scale.
