The blank compose window is the enemy of productivity. You know what you want to say, but finding the right words, the right structure, the right tone takes time. Especially when English is not your first language.
Kerna's Compose feature eliminates the blank page problem entirely.
From Bullets to Business Email
Here is how it works. Open a new compose window in Gmail, click Kerna, and type your intent in shorthand:
*"meeting tuesday 2pm, budget review, bring Q1 numbers, confirm attendance by monday"*
Click Compose and Kerna generates:
*Subject: Budget Review Meeting — Tuesday 2:00 PM*
*Dear team, I'd like to confirm our budget review meeting scheduled for Tuesday at 2:00 PM. Please come prepared with the Q1 figures. Kindly confirm your attendance by end of day Monday...*
The output is a complete, formatted, professional email ready to send or edit.
Tone Control
Kerna adapts to the tone you set in your preferences. Choose from:
- Professional — Formal business correspondence suitable for clients and executives.
- Friendly — Warm but professional, ideal for internal team communication.
- Direct — Short, action-oriented messages that skip the pleasantries.
- Custom — Define your own tone instructions in the settings panel.
You set this once in your Kerna preferences, and every composed email follows your style automatically.
Multi-Language Composition
You can type your keywords in English and have Kerna compose the email in any of 45 supported languages. This is particularly powerful for international teams — think in your native language, send in the recipient's.
Use Cases
Managers use Compose to send structured project updates from quick notes taken during meetings.
Sales professionals use it to generate personalized outreach emails from CRM bullet points.
Non-native speakers use it to ensure their emails sound fluent and professional without second-guessing every sentence.
