Coherence vs Gmelius

Coherence is a customer operations platform connecting CRM data, communications, workflows, websites, campaigns, and AI agents. Its Shared Inbox gives sales, support, and operations a common place to handle incoming conversations with customer context, replies, and internal discussion. Teams can assign conversation ownership, add internal notes, view teammate presence, and work on shared drafts. Inbox categories, custom fields, rules, assignment settings, response targets, snoozes, and reminders help organize queues. Staff can select published Knowledge articles and review suggested replies with source references, then edit drafts before sending; AI generation uses the workspace's configured AI provider. Shared Inbox is available on Pro, Team, and Enterprise. Listed integrations include two-way Gmail or Outlook email sync, Google or Microsoft Calendar sync, and a REST API. Coherence says data is encrypted at rest with AES-256 and in transit with TLS 1.2 or higher, and stored in the United States. The service is not currently available in the EEA, UK, Switzerland, Australia, Canada, and several other regions. Pro costs $29 a month per user; Team requires at least 10 paid seats.

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).
