Social Layer is a free Chrome extension that improves email communication by helping users avoid misunderstandings in Gmail. This tool analyzes the tone and context of your messages right before you hit the Send button. If it detects potential emotional escalation or misinterpretation, it suggests a brief pause, allowing users to reconsider their message, especially in high-pressure situations or when the content may be perceived as harsh.

The extension maintains user control by not altering the content of emails or blocking sending. It operates subtly to ensure minimal interruption while effectively providing a moment of reflection. Importantly, all processing occurs locally in the browser, ensuring that email content remains private and secure, without being stored or transmitted externally.
