What is Auto Localize?
Auto Localize is a desktop localization tool aimed at developers and teams who need to translate and maintain app content across multiple languages. It focuses on reducing the manual work involved in updating localization files when apps change, and it supports both manual editing and AI-assisted automation.
The app can open and edit common localization formats directly, including XLIFF and XCLOC, and it also works with project-based localization flows for formats like XML, JSON, ARB, STRINGS, RESX, and PROPERTIES. It can inspect project structure to identify source and target languages and determine which items should be localized.
A major feature of the tool is its PRO automation layer, which can localize an entire project with one click using AI services. The website says it supports Gemini AI, OpenAI models, and local LLM apps such as LM Studio and Ollama, giving users flexibility between cloud-based and offline workflows.
The tool is for developers working in Xcode, Android Studio, Java, Flutter, Unity, and related app ecosystems, as well as people managing App Store Connect content and localized screenshots. It is especially useful for anyone who wants to speed up repetitive localization tasks, reduce API usage through caching, and keep translations organized inside an app-centric workflow.
Auto Localize pricing
Pricing model: Free
Auto Localize has a free editor tier that lets users download the app and manually edit localization files without paying. The PRO version requires a paid monthly subscription and unlocks AI localization, caching, and multi-item localization. Each active month of PRO adds 10,000 free localization credits, and AI localization actions consume credits based on item size. When credits run out, users can either buy credit packages from the in-app Localization Credit Store or wait for the next monthly credit refill. The website says monthly subscription credits and purchased credits never expire, and unused credits remain available even if a subscription is canceled and later reactivated.

Frequently asked questions about Auto Localize
What is Auto Localize used for?
Auto Localize is used to localize app projects and related content into multiple languages. It supports manual localization file editing and AI-driven project localization, so developers can manage translations for apps and app store assets in one place.
Which project types does it support?
The website says Auto Localize supports Xcode, Android Studio, Java, Flutter, Unity, and related localization workflows. It also mentions App Store Connect data and localized app store screenshots as part of the toolset.
Which file formats can it handle?
It directly supports XLIFF and XCLOC, including XLIFF versions 1.2 and 2.0. It also supports localization-related formats such as XML, JSON, ARB, STRINGS, RESX, and PROPERTIES, though some of those are handled through project folders rather than opened as standalone files.
Does Auto Localize work without AI?
Yes. The website describes Auto Localize as a free editor application for manually editing localization files. AI localization is available only in the PRO version.
What does the PRO version include?
PRO unlocks automatic localization using AI, caching, and multi-item localization. It also enables the use of AI providers such as Gemini, and the website says you can use local LLM apps like LM Studio and Ollama as part of the supported AI workflow.
How do localization credits work?
Each active month of PRO adds 10,000 free localization credits. AI localization actions use credits according to the size of the localized items, and when credits are exhausted, the AI localization service cannot be used until more credits are added.
Can I buy more credits?
Yes. The website says users can purchase credit packages from the in-app Localization Credit Store when their credits run low or run out. Users can also wait for the next monthly PRO renewal to receive another 10,000 credits.
Do unused credits expire?
No. The website states that credits from the PRO subscription and credits purchased from the store never expire. It also says unused credits remain available even if a subscription is canceled and later reactivated.
What is caching in Auto Localize?
Caching stores prior localization results so the app can reuse them instead of calling the AI service again for the same source language, target language, and source text combination. The website says this helps prevent unnecessary credit consumption and also updates the cache when a user manually localizes an item.
Is the AI localization service available on the free tier?
No. The website says the AI localization service is a PRO feature, so it is not available unless the PRO subscription is active.
