Direct answer
What is Ellie?
Ellie is an AI inbox assistant for Gmail and Outlook that automatically drafts contextual email replies in your personal writing style. Operating directly inside your existing mail client, it leverages sent-mail patterns, website crawls, and uploaded reference materials to prepare ready-to-review responses without sending messages automatically.
Ellie connects directly to Gmail, Google Workspace, Outlook, and Microsoft 365 to automate email response drafting. Rather than requiring users to open a standalone dashboard or write explicit prompts, Ellie operates in the background. It reviews incoming threads overnight or on demand, determines which emails require replies, and generates completed response drafts directly into your client's Drafts folder. The system learns your specific writing style by analyzing previously sent emails, mimicking your customary greetings, sign-offs, sentence structures, and typical message length. Users can configure plain-language categories (such as sales inquiries, billing, or general support) and assign distinct reply voices or personas to each, ensuring that financial matters receive a direct tone while sales inquiries remain warm. For factual accuracy, Ellie incorporates knowledge base training. Users can point the assistant to public URLs—such as help centres and pricing pages—or upload documentation including PDF, TXT, and DOCX files. Ellie references this data when assembling replies and is programmed to avoid fabricating facts when information is absent. Structured data lookups can also pull dynamic records like renewal dates or ticket statuses. Ellie strictly generates drafts; it does not send outgoing emails without manual user review and approval.
Unlike standalone generative AI writing tools that require copy-pasting prompts, Ellie works directly within native Gmail and Outlook Drafts folders overnight, mimicking your observed sent-mail habits and switching distinct tone profiles across custom plain-text categories.
