Slack
Application
Team messaging platform for channels, direct messages and huddles, sold in Free, Pro, Business+ and Enterprise+ tiers.
Bundle of AI features built into Slack -- channel and thread summaries, daily recaps, AI search answers, huddle notes, translation and AI-assisted workflows -- unlocked from Pro through Enterprise+ (none of it ships on Free), distinct from the standalone Slackbot agent.
AI agent
Personal AI agent built into Slack that answers from a user's messages, files and channels, drafts content, schedules meetings and takes actions, within existing permissions.
Zendesk
Application
Contact-centre add-on on the Zendesk Resolution Platform that puts voice, digital and self-service in one agent workspace; its Voice AI agents understand caller intent, apply the company's policies and resolve calls end to end, while Voice Copilot takes notes, summarises and reads sentiment in real time for human agents.
An AI assistant add-on for Zendesk that gives human support agents in-workspace guidance, auto-assist suggestions and intelligent triage, and gives admins proactive workflow recommendations.
AI-assisted knowledge-base building and maintenance: unifies service and third-party content, generates ready-to-use articles, and grounds AI/human agents with a single knowledge foundation.
An AI-powered support QA add-on that auto-scores human and AI agent conversations via AutoQA, flags high-risk interactions with Spotlight, and drives targeted coaching.
Forecasting and scheduling add-on for Zendesk support teams: it analyses a team's historical ticket data to predict how many agents a day, month or season will need, builds schedules down to the minute, and tracks what agents are working on in real time.
AI agent
Autonomous agents that resolve multi-step customer-service requests across messaging, email, voice and social channels, learning from each resolution and escalating to a human agent when needed.
AI agents purpose-built for internal IT and HR support that retrieve permission-scoped answers from enterprise sources such as SharePoint, Google Drive and Confluence and execute workflows from inside Slack or Microsoft Teams.
