How to Translate Text with OpenAI on Mac
Translate text between languages instantly in any Mac app using OpenAI's GPT models through Echoo. Select text, press a shortcut, and get natural-sounding translations without switching to a browser.
Why This Combination Works
OpenAI's GPT models produce translations that read naturally in the target language, avoiding the literal word-for-word output that traditional machine translation tools often produce. GPT-4o handles idiomatic expressions, cultural context, and tone adaptation exceptionally well across over 100 languages. It also excels at translating domain-specific content like legal, medical, or technical text without losing precision.
Recommended Model
GPT-4o is the best choice for translation tasks. Its multilingual training data is extensive, covering both high-resource languages like Spanish and French and lower-resource languages like Swahili and Welsh. For high-volume translation of simpler content, GPT-4o Mini delivers surprisingly good quality at one-tenth the cost.
Example Prompt
Translate the following text to English. Preserve the original formatting, paragraph breaks, and any proper nouns. Produce a natural, fluent translation rather than a literal one. Return only the translated text.
