Acceptance of terms.

Description of service.

LinguaAI is a suite of applications for macOS, iOS, and watchOS. The AI-powered apps (LinguaAI Pro, Studio, Admin, Terminology) provide an interface to connect with third-party AI providers including Anthropic Claude, OpenAI, Google Gemini, Mistral AI, and others, using a Bring Your Own Key (BYOK) model. LinguaTrans is a local-only CAT (computer-assisted translation) tool that does not use AI or connect to external services. The Verdict and Sillage are companion apps with their own BYOK integrations (TMDB and Fragella respectively).
