Best Practices & Tips

WhatsApp is the world's most used messaging platform, and for Mac users who access it through WhatsApp Web or the desktop app, Echoo brings AI-powered text transformation to every conversation. Translation and grammar correction are especially valuable given WhatsApp's global, multilingual user base.

The primary workflow for WhatsApp is quick message polishing. WhatsApp conversations move fast, so speed matters. Type your message naturally in the compose field, select it, and press your shortcut. Echoo replaces the text in place, and you hit send. The entire polish-and-send flow takes seconds. Use in-place replacement mode rather than popup for WhatsApp to maintain conversational speed.

Translation is the killer feature for WhatsApp users. Many people use WhatsApp to communicate with family, friends, and business contacts who speak different languages. Set up one-shortcut translation for your most common language needs. Type in your native language, select, translate, and send. For incoming messages in foreign languages, select and translate to understand them instantly.

For business users on WhatsApp, the Professional Tone command helps maintain a professional image in business chats and groups. WhatsApp is increasingly used for business communication in many regions, and the line between casual messaging and professional communication is thin. A quick tone adjustment ensures your business messages are clear and polished without being overly formal for the WhatsApp context.

WhatsApp Web works in any browser, and Echoo functions identically across Chrome, Safari, Arc, Firefox, and others. The WhatsApp Desktop app is also fully supported. Whether you prefer the browser or native app experience, Echoo shortcuts work the same way.

Create a "WhatsApp Business Reply" command for professional conversations that balances warmth with clarity. WhatsApp business communication has a unique tone: more personal than email but more professional than casual messaging. The AI can be instructed to match this hybrid tone with specific prompt instructions.

Google Gemini is the top choice for WhatsApp use thanks to its fast responses, free tier, and strong multilingual support across dozens of languages commonly used by WhatsApp's global user base.
