Tonemail is an AI-powered email drafting application designed to help users write emails quickly and confidently using predefined tones such as professional, friendly, formal, or casual. The idea for Tonemail came from a simple observation: while many people rely on tools like ChatGPT or other AI assistants to draft emails, the experience often feels fragmented, generic, or disconnected from real writing workflows. Users frequently switch between tools, adjust prompts manually, and rewrite outputs to match the intended tone. Tonemail explores how AI can be packaged into a focused, usable product, where tone selection, clarity, and control are prioritized over prompt complexity. Instead of exposing AI mechanics, the interface is designed around user intent: choosing a tone, generating content, and refining it quickly.
