Preferred Localization
What Preferred Localization is
Preferred Localization is a paid localization platform combining AI translation, quality review, terminology management, and developer integrations. It can reference existing translations, extract terms into glossaries, and analyze context. Projects can set tone, item context, and labels, while the workflow supports batch drafting, checks for omissions and terminology mismatches, revision proposals, and approval. Listed format examples include Word, Excel, CSV, JSON, PDF, and TXT, with additional formats considered for customer needs. Browser review, an API for systems and CMSs, and a CLI for syncing locale files provide integration options. Models include GPT, Gemini, Gemma, Qwen, gpt-oss, and PLaMo Translate. Deployment can be cloud or on-premises, including private-network and offline environments. Stated uses cover games, web content, SaaS and apps, and documents. Pricing is on request, and tailored demos are offered. Japanese terms restrict applications to corporations in Japan and use by their officers or employees. The terms also prohibit entering sensitive personal information.
