What is LocIn AI?
LocIn AI is a developer-focused localization platform that translates app strings while preserving brand tone, variables, and UI context. The tool uses tone-aware AI to ensure translations sound like your brand across 50+ languages, addressing the common problem where generic LLM translation produces technically correct but toneless output. LocIn reads components and comments rather than translating raw JSON in isolation, understanding context like whether

Frequently asked questions about LocIn AI
What does 'tone-aware' mean and how does it work?
Tone-aware AI means the translation preserves your brand voice—casual, technical, playful, or whatever you define. When context is thin (like a two-word button), LocIn leans heavily on the tone profile, glossary, and rest of project content to understand how your product communicates. The model gets a stronger understanding of the product itself rather than treating every string independently, which produces much better results than isolated string translation.
How does the CLI work and what frameworks does it support?
The CLI runs a full pipeline in one command: scan, setup, extract, upload, translate, export, and validate. It automatically detects React, Next.js, Vue, Nuxt, and standard i18next setups. For custom projects, you can configure paths. The CLI scans your codebase, fixes hardcoded strings, sets up i18n, syncs translation files, and can be hooked into your flow locally or in CI.
What happens if a translation breaks a placeholder like {{count}} or {{planName}}?
CI validation catches placeholder mismatches and will fail the check. The validation goes beyond basic checks—it catches missing keys, broken file structure, untranslated content, and ensures HTML tags are preserved. It also warns when a translation is dramatically longer or shorter than the source.
Do I ship AI translations straight to production without human review?
No. LocIn has multiple review and validation layers that check translations, flag potential issues, and recommend manual review when confidence is low. The goal isn't to remove humans entirely but to dramatically reduce manual work while keeping quality high. Teams should still review high-visibility onboarding, billing, legal, support, or culturally sensitive copy.
What localization formats does LocIn support?
LocIn supports all major localization formats including JSON (i18next, react-intl), YAML, PO/POT (gettext), XLIFF, ARB (Flutter), and more. The system auto-detects your format and handles it appropriately.
How does LocIn handle language pairs with different formality rules like Japanese honorifics or French tu/vous?
The tone profile, glossary, and project content build understanding of how your product communicates. While LocIn doesn't claim to solve context perfectly every time, giving the model stronger product understanding gets much better results than treating strings independently. Teams should test for language-specific issues like honorific levels.
Can I override AI translations if I don't like them?
Yes. You're always in control of the final output and can override any AI translation with your preferred text. The review layers flag potential issues but don't force acceptance of translations.
What happens when strings change or new strings are added?
New strings are detected automatically. Changed strings get re-translated. Deleted strings get cleaned up. This keeps your translation files in sync with your codebase without manual spreadsheet management.
Does LocIn work with specific frameworks like React, Vue, Angular, Next.js?
Yes. LocIn works with React, Vue, Angular, Next.js, and more. The CLI automatically detects React, Next.js, Vue, Nuxt, and i18next setups out of the box.
