React i18n translation FAQ
Which React i18n libraries are supported?
Native compatibility with next-intl, react-i18next, react-intl, LinguiJS, and Remix i18n JSON files.
Are {{variable}} interpolation placeholders preserved?
Yes. Variables inside double braces ({{count}}, {{userName}}) and component placeholders ($t(key)) are treated as immutable tokens and preserved exactly.
Does AI Glot support ICU MessageFormat plurals and gender rules?
Yes. Complex ICU syntax like {count, plural, one{# item} other{# items}} is recognized and translated with valid target language plural rules.
Is JSON syntax and indentation guaranteed to be valid?
Yes. All generated files pass JSON.parse() validation. Quotes, commas, arrays, and nesting depth are strictly preserved, matching your project's indentation.
Why not copy-paste JSON into ChatGPT?
ChatGPT frequently truncates files over 100 lines, hallucinates keys, misses nested sub-objects, or outputs unescaped quotation marks that crash your build. AI Glot guarantees 100% structural fidelity.
Can I translate newly added keys without overwriting existing translations?
Yes. You can upload updated JSON dictionaries to populate missing keys while keeping human-approved strings untouched.
How does AI Glot handle short UI labels like Save or Close in context?
By analyzing surrounding keys and parent object context, AI Glot accurately distinguishes verbs from nouns (e.g. Save as an action vs Save as a discount).
Is there a free tier for React developers?
Yes. Upload your locales/en.json file into the free tool above to translate strings immediately with zero credit card required.
