Demi is an AI assistant that runs on your Mac and works across the tools where business conversations happen: Gmail, Google Calendar, Slack and CRMs such as HubSpot. Its stated aim is to get work done before it slips, which in practice means drafting the replies you owe, chasing follow-ups that have gone quiet and preparing meetings.
Unlike a general chatbot, Demi starts from your accounts. It reads the thread, the invite and the call notes together, then prepares the next step for review. A typical output is a drafted reply that already contains the agreed pricing, or a staged CRM update with a new deal stage and next step.
The product is aimed at people who live in their inbox, including founders, sellers, recruiters and customer success managers. Its website features testimonials from people in those roles, mostly describing drafts that match their own voice.
Setup has three steps according to the company: download the Mac app, connect your tools, and see what Demi found. Once accounts are connected, Demi surfaces what needs attention, for example a reply waiting on you or a deal that has been quiet for eleven days, and prepares the next action.
Demi learns from how you work rather than from a setup wizard. It keeps notes such as tone by audience, preferred summary format, sign-off and scheduling preferences. When a task repeats, it offers to take it over, and you decide whether to keep the pattern.
Demi also routes each job to a suitable model automatically, so a quick reply and a large multi-source brief are handled differently. Organizing, remembering and preparing happen on their own. Anything external comes to you for approval first.
The core feature is drafting. Demi writes email replies using the thread and the call behind it, and writes short follow-ups that offer something useful rather than asking for a status. After meetings it records what you promised, what the other party asked, and the dates mentioned, then drafts a recap and lists open tasks.
On the CRM side, Demi fills in deal stage, next step and last activity from what was said and stages the change in HubSpot. It also prepares meeting briefs and can rebuild them when circumstances change.
Control features include approve, edit or skip on every consequential action, and a Pause option in the menu bar that stops new work without disconnecting tools. Paid plans add routines that run on a schedule, morning and nightly digests, priority speed, and the ability to call Demi from any app or screen.
