💡 What is HumanLetter?
HumanLetter is a Chrome extension that adds authenticity certificates to your Gmail emails, proving they were written by a human rather than generated by AI or sent through automation tools.
💡 How does the verification work?
Our proprietary technology analyzes your writing patterns in real-time as you compose emails in Gmail. When human authorship is detected, we automatically generate a unique verification certificate linked to your signature.
💡 Is my email content stored?
No! HumanLetter only verifies that a human wrote the email - we never store, read, or access your actual email content. Your privacy is our top priority.
💡 How do recipients verify authenticity?
Recipients can click on the verification link in your email signature to view a secure certificate page that confirms the email was written by a human, along with verification details.
