Localization without the busywork.
Everything between “English only” and “live in 50 locales” — handled.
AI that knows ASO
Claude translates with App Store context: keyword intent, tone, and the character limit of every field. Not word-for-word output — copy that ranks.
Straight to App Store Connect
No spreadsheets, no copy-paste. Translations are written to your app version through the App Store Connect API the moment they’re ready.
Every field covered
Description, keywords, promotional text, What’s New — pick exactly which fields to translate and which to leave alone.
Your keys stay yours
App Store Connect credentials are sent per request and never stored on a server. The API is stateless by design.
Live per-language progress
Watch each locale complete in real time, cancel mid-run, and re-run only what changed. Existing translations are never overwritten unless you say so.
Your voice, every language
Add custom instructions — brand terms to keep, tone to match, words to avoid — and they apply across all 50 locales.
Three steps. A few minutes.
Connect
Upload your App Store Connect API key (.p8) with its Key ID and Issuer ID. Credentials never leave your browser session.
Choose
Pick an app, a version, the fields to translate, and any of the 50 App Store languages as targets.
Translate
AI translates every field within its character limit and uploads the results to App Store Connect. Review in Connect, then submit.
Why translate your App Store metadata at all?
App Store search is local. When someone in Tokyo, Berlin or São Paulo searches the App Store, they type in their own language — and Apple’s search index matches against the keywords and name of your listing in that locale. If your app only has English metadata, it simply doesn’t rank for those searches.
Localized listings also convert better once found. Apple has said users are far more likely to download an app presented in their native language, and developers routinely report double-digit conversion lifts after localizing just the description and screenshots’ captions.
The catch has always been effort: 50 locales × 4 fields, each with its own character limit, managed through App Store Connect one language at a time. That’s the part StoreTranslate removes. Read the full App Store localization guide or start with the two highest-impact fields: keywords and the description.
All 50 App Store languages.

Frequently asked questions
What App Store metadata can StoreTranslate translate? ＋
The description, keywords, promotional text, and What’s New (release notes) for any app version in an editable state. You choose per field — for example, translate keywords and description but leave your app name untouched.
Which languages does the App Store support? ＋
App Store Connect supports 50 localizations, from German and Japanese to Ukrainian and Catalan. StoreTranslate can translate into all of them in a single run.
Does it respect App Store character limits? ＋
Yes. Each field is translated against its App Store Connect limit — 100 characters for keywords, 170 for promotional text, 4,000 for the description and What’s New — so uploads never fail validation.
Are my App Store Connect credentials stored? ＋
No. Your .p8 key, Key ID and Issuer ID are included with each request and used only to talk to Apple’s API. The backend is stateless and stores nothing.
Will it overwrite translations I already have? ＋
Only if you ask it to. By default, existing localizations are left in place and only missing ones are filled in.
Is machine translation allowed for App Store metadata? ＋
Yes — Apple doesn’t restrict how you produce your metadata, only that it’s accurate and follows the App Store Review Guidelines. AI translation with human review is how most localized listings are made today.
