LangSync is an AI-powered localization platform built for developer and product teams that ship globally. Manage all your translation strings in one place, let AI translate with full context awareness, and export i18n-ready JSON via REST API or CLI – straight into your build pipeline. Unlike traditional TMS tools that bolt AI on top of a translation memory, LangSync is AI-native. Every translation runs through your glossary, your custom tone prompts, and the term's surrounding context – so brand names stay consistent, UI strings sound like your product, and technical vocabulary doesn't get mangled in transit. Key capabilities: - AI translation across 100+ languages using the IETF BCP 47 standard, including country-specific variants like en-US, pt-BR, and zh-TW - Glossaries with type categorization (brand, UI, technical, billing) and translatability flags to lock brand names as-is - Custom translation prompts for tone, formality, and domain context - Namespace-based projects to isolate apps, modules, or client work - Bulk CSV import with optional auto-translation on ingest - REST API with API key authentication for i18n JSON export - norcube CLI for two-way sync between LangSync and your local i18n files — resumable jobs survive backend restarts - One-click POEditor migration: terms, languages, and translations move over automatically - Namespace-level roles and per-language contributor access for team collaboration Built for SaaS products, mobile apps (iOS, Android, React Native, Flutter), agencies managing multi-client projects, e-commerce stores, and open source maintainers running community translations. Three pricing principles we don't break: empty translations are always free (you only pay for strings with content), no per-seat pricing (invite your whole team), and no vendor lock-in (export everything via API anytime). Free tier of 1,000 strings forever, no credit card required.
