Most AI email tools give generic, robotic responses. GhostPen learns YOUR writing style by analyzing your sent emails, then generates contextual responses in one click—right in Gmail. It remembers how you communicate with each contact (formal with clients, casual with teammates) and adapts automatically. Save 2+ hours daily on email without sacrificing authenticity. Built for sales teams, account managers, and professionals drowning in their inbox. Use our handy calculator on website.
