In their own words
Gmelius
Gmelius is a Gmail-native platform for creating AI agents that carry out defined team jobs across connected tools. Users describe an agent’s task in plain language, choose the inbox it monitors, connect tools, and decide which actions need approval, without writing code. Meli, described as an AI Chief of Staff, supplies agents with context about a team’s clients, history, and priorities. Gmelius also provides shared Gmail inboxes and labels, shared drafts, email notes and mentions, delegation, templates, analytics, calendar tools, and scheduled sending. Listed integrations include Google Groups, Google Workspace Admin, Meet, Calendar, Salesforce, HubSpot, Slack, Trello, Nicereply, Zapier, Make, and Relay.app. The Gmail extension supports Chrome, Microsoft Edge, Brave, and Opera; listed platforms also include Android, iOS, API, and web. There is no free plan, but a seven-day trial gives access to Growth; afterward, users must choose a paid plan or the account is suspended. Prices start at $19/user/mo (annual).
