Ellie is an AI email assistant that connects to a Gmail or Outlook mailbox and writes reply drafts on the user's behalf. The drafts sit in the Drafts folder, in the correct thread, ready to review. Nothing sends until the user decides, so the user stays in control of every message.
The product targets people who spend a large share of the day answering email, from founders and solo consultants to sales and support teams. The company reports 2.3 million replies drafted and an average of 42 minutes saved per day, figures taken from its own website rather than independent testing.
Setup starts by connecting a Gmail or Outlook account in the web app. Ellie then reads the user's sent mail to learn tone, openers, sign-offs and typical reply length. The company says this avoids rigid templates and identical replies, since drafts reflect how the person already writes.
After that, Ellie works in the background. It reads threads that need a reply, writes drafts overnight and files them in the Drafts folder. Users can instead trigger replies on demand with the browser extension or the Outlook desktop add-in. The company states that each thread is discarded after the draft is written and is not used to train general models.
The category system is a central feature. Users describe each category in a sentence, such as anything asking the company to pay or renew, and Ellie files incoming mail accordingly. Categories control whether a draft is written, whether a task with a due date is created, and which voice the reply uses. Six defaults are provided and can be renamed or replaced.
For business use, Ellie offers Knowledge Base Training from a website URL or uploaded PDF and document files, plus live lookups from connected CRM, e-commerce, helpdesk or billing systems. Roles give each kind of email its own tone and knowledge base, and replies can be written in any language.
