About
Echoo is a macOS app for people who work in English but think in another language.
Write the message in your own language - Spanish, Arabic, Hebrew, Japanese, anything - select it, press one keyboard shortcut, and it becomes English in place, in the app you were already using. Mail, Slack, Notion, Word, your browser. No copy-pasting into a chat window, no switching apps.
The point is that it keeps your voice. This is not literal translation: your tone and register carry across, so a direct message stays direct and a warm one stays warm, instead of arriving as stiff textbook English that does not sound like you.
Start with 10 free credits - no credit card, no API key.
Echoo does not store your processed text. Pro Mode routes through Echoo's OpenAI API project, where content is not used to train models - unlike pasting work into a consumer chatbot. If text must never leave your Mac, Free Mode runs the same commands against a local Ollama model.

About
Speechify’s text-to-speech API offers a family of Simba models for real-time voice generation across English, European languages, and broader multilingual use cases. Simba 3.2 is recommended for new English integrations, providing streaming-native synthesis, the lowest time to first byte, richer expressivity than earlier generations, and full support for SSML and emotion control. Simba 3.0 extends streaming-native speech to English, German, Spanish, French, Italian, and Brazilian Portuguese, with language selection handled through the request or voice locale. Simba Multilingual supports 35 locales across 30 languages, including mixed-language content and automatic language detection, while Simba English remains available as a legacy model for compatibility. Developers select a model through one parameter and can switch without changing the rest of the request structure, including voice, format, and SSML settings.
