Cihat was super-responsive to feedback on TranslateKit when I contacted him (made a request Saturday, update in App Store on Monday!). I'm excited to see where TranslateKit goes, especially with his years of experience in this space.

Reach 1 Billion People within minutes. We added support for Hindi, Bangia and Urdu in MoneyCoach. Something it would have cost us thousands of dollars. TranslateKit is a no brainer for all app developers. Highly recommended.

Tried TranslateKit: it's really amazing! Added a new localization to my app today in no more than five minutes – just drag & drop a few files into TranslateKit. Congrats!

Localized Snel to five languages (German, French, Dutch, Spanish and Simplified Chinese) and added a complication for easy access. Since there's only very basic strings in here I used TranslateKit which uses DeepL

TranslateKit has been a great help in localizing my first app. Excited to see it grow and all the changes along the way.

It seems like a great flow to use TranslateKit to get initial translations, and then a crowdsourcing tool to improve them. I've just tried TranslateKit and it works great!

My time tracking app Moons is now also in Swedish! This time TranslateKit helped me to localize my app faster than using ChatGPT and Google Translate alone.

Clean, simple, works. Like it says on the tin. You can even link up to a Google Translate account (or one of the other services) and have the translations done automagically. 5 stars!

FAQ

How does AI translation work?

Unlike traditional services that translate strings in isolation, our AI understands your app's context, purpose, and terminology. We batch your strings together and provide the AI with crucial information about your app, ensuring accurate translations that feel natural in each language. There's no API setup needed – just select your languages and let TranslateKit handle everything. Note that we constantly evaluate and fine-tune our prompts to make translations as accurate as possible.

How does AI proofreading work?

Our AI proofreading uses an advanced model specifically tuned for app localization. It checks for context accuracy, UI-appropriate language, consistent terminology, regional variants, length constraints, culture-fit, language-specific rules, formality & gender and much more! Proofreading is optional but recommended for critical markets. Proofread strings are marked as verified, and you can run multiple passes if needed.

What's included in each plan?

All plans include our core features: AI translations, AI proofreading, unlimited projects, TranslateKit SDK, and our smart Translation Editor. The difference is in the monthly AI tokens: Basic ($0.99) gives 50 tokens monthly – perfect for small apps. Pro ($2.99) gives 200 tokens monthly – our most popular plan. Ultra ($9.99) gives 750 tokens monthly – best value for larger apps.

How many tokens do I need?

As a rough guide: Small apps (200 strings) need ~8 tokens per language for translation, ~18 for proofreading. Larger apps (500 strings) need ~20 tokens per language for translation, ~45 for proofreading. Pro tip: Start with our Basic plan and purchase additional tokens as needed.

Can I still use DeepL/Google/Microsoft?

Yes! While our AI translations offer superior accuracy and context awareness, we've kept our Classic Mode for those who prefer traditional services. You can still use your existing API keys with DeepL, Google, or Microsoft for translations.
