If you want to automate the translation process for your Xcode project, Xpolyglot is well worth a look. This macOS app uses AI to automate localization, letting you import projects, manage translations in a centralized way and keep up with changes. It requires an OpenAI API key for Magic.xcstrings but offers lifetime free updates for a one-time $9.99 purchase, a big step down from paying translation services.
Another good choice is Lokalise, a continuous localization and translation management service. It can be integrated into development processes, including GitHub, Bitbucket and Jira. Lokalise offers collaborative workspaces, AI-powered translations and quality assurance tools, so it's good for managing a variety of content, including software apps and marketing materials.
If you have a broader translation need, Lingvanex offers a platform with AI-powered tools that work with more than 100 languages. It can run on multiple platforms and integrates with iOS, Android, Windows and Mac. Lingvanex offers customizable options for customer support and language learning, and it has different pricing tiers for different business needs.
Last, O.Translator offers a context-aware translation engine that works with more than 60 languages and many file types. It's got data security with Google's protected storage and collaborative translation abilities. Pricing is based on the number of words translated, but O.Translator is a good option if you have a lot of text.
