I built a free tool to translate Android, iOS, and Flutter string files (and here's how the translation actually works under the hood)

Every time I’ve localized an app, it’s gone one of two ways: hand-translate
the strings myself (slow, and my Spanish/French/whatever is not great), or
set up a full localization platform for what’s really a five-minute job on
a small project.

So I built StringLingo AI — a free
tool that translates:

• Android strings.xml
• iOS Localizable.strings
• Flutter .arb files
• Or just plain pasted text

Upload the file, pick a target language, download a translated file with
the same keys and structure. No account, nothing stored.

The part I actually want feedback on

The interesting problem wasn’t the UI, it was not breaking your strings
while translating them. Localization files are full of things a naive
translation pass will mangle:

xml
<string name="welcome_message">Hello %1$s, you have %2$d new messages</string>
