MailBuddy

MailBuddy is a ChatGPT overlay tool that writes Gmail replies in five seconds with a ChatGPT extension. A free Chrome extension that drafts contextual Gmail replies with GPT, accepts written instructions for tone and form, and lets users edit or regenerate before sending.

MailBuddy is a Chrome extension that drafts email replies inside Gmail using GPT models. It sits in the reply box rather than in a separate app: open a message, hit reply, and a small panel appears at the top right corner of the compose area. From there the tool reads the previous message and generates a response in context, and the user reviews the draft before sending. The pitch is narrow and deliberate, it handles replies only, not new outbound emails. The control model is what separates it from a plain text generator. Users can type an instruction into the input field to shape the output, and the site lists three kinds of direction it recognizes: specific details to include (extra information, examples, questions), sentiment (polite, positive, formal, funny), and form (bullet points, a set number of tips, brevity). Drafts can be regenerated as many times as needed, and everything is editable before it leaves the mailbox. The vendor positions the tool as a writing assistant, with the human approving rather than delegating the send. Setup is intentionally minimal. There is no training step, no account to create, and no login inside the extension, which the site frames as a privacy point: access is limited to the email text at the moment of activation. That makes it a low-friction fit for freelancers, support staff and office workers who answer a high volume of routine correspondence and want a first draft without leaving the inbox. It competes with broader email assistants that add scheduling, triage or CRM sync, and it does not try to match them on scope. The site also notes a related product for building a chatbot on a company website, aimed at teams that want answers grounded in their own content.
