Translate Any Language on Mac with AI

Echoo brings the power of large language models directly into your macOS workflow for seamless, context-aware translation. Unlike traditional translation tools that require switching between browser tabs or dedicated apps, Echoo lets you translate selected text in most applications with a single keyboard shortcut. Whether you are drafting an email in English and need a quick French version, or reading a Japanese article and want an instant English summary, Echoo handles it natively on your Mac.

Powered by state-of-the-art AI models from OpenAI, Anthropic, and Google, Echoo delivers translations that understand context, tone, and idiomatic expressions - not just word-for-word replacements. The result is natural, fluent text that reads as if it were written by a native speaker. You can customize the translation style (formal, casual, technical) and even ask the AI to preserve specific terminology for your industry.

Echoo currently has guides for 40 language pairs, including Spanish, French, German, Portuguese, Chinese, Japanese, Korean, Arabic and Hebrew. In Free Mode, translations use your own API keys or local models, and Echoo does not store your processed text. Each guide below covers what makes that specific pair difficult, an example translation, the model we recommend for it, and whether voice dictation is available.
