[ Why translate ]

Localization is the most overlooked revenue driver

Most app teams focus on UA and conversion while leaving entire markets untapped. A single strings file stands between you and 5× the audience.

More languages, bigger audience

Every new language typically increases downloads by 25-50%. Reaching Spanish speakers alone can triple your addressable market overnight.

40 languages, fully supported

From Spanish to Arabic to Japanese - including full RTL support. Every language is production-ready, not an afterthought.

Upload once, ship everywhere

Drop in your native strings file. Transolve reads your format, translates every key, and returns an identical file ready to drop back into your repo.

Edit, override, publish

Review AI translations inline, override any key, and publish when you're ready. No engineers required.

[ How it works ]

Four steps to a global app

No new tooling. No localization engineers. Just your existing strings file and a few clicks.

01

Generate your localization file

Export your strings file from your project - .xcstrings or .strings for iOS, .xml for Android, .arb for Flutter.

02

Upload to Transolve

Drop your file straight into the platform. Transolve parses every key and groups them for review.

03

Choose up to 40 languages

Select the markets you want to reach. AI translates every string with context-awareness tuned for app UI copy - not generic machine translation.

04

Download & ship

Download your fully translated file in the same format you uploaded. Drop it back into your repo and deploy to new markets.

Transolve supports .xcstrings and .strings for iOS, .xml for Android, and .arb for Flutter. You upload your native project file and get back the same format, fully translated and ready to drop into your repo.
Typically seconds to a few minutes depending on file size. A standard iOS .strings file with a few hundred keys translates across all 40 languages in under two minutes.
Translations are context-aware and tuned for app UI copy - not generic machine translation. The model understands that "Save" in a button context means something different than "Save" in a document. You can review and override any key inline before publishing.
Yes — Arabic and Hebrew are fully supported including RTL string handling. The exported file is structured correctly for RTL layouts out of the box.
Yes. Every translated key is editable inline inside Transolve. Override AI output, add context notes, and lock strings you want to keep unchanged on future runs.
Your localization files are used solely to process your translations. Data is deleted after project completion.
No. Upload your file, pick your languages, download the result. The entire flow is self-serve. Engineers only touch it when they drop the translated file back into the repo — which takes under a minute.
