Each term, explained
AI coworker: a shared teammate in Slack
An AI coworker is a shared AI teammate that sits in your work chat (usually Slack or Microsoft Teams). Multiple people can @mention it and get work done. It's designed for team collaboration: briefs, reports, handoffs, summaries.
Key attribute: Shared—anyone in an invited channel can direct it.
Examples:
- Geniusly — AI coworker for team briefs, reports, and handoffs in Slack
- OpenTag — General-purpose AI coworker with 40+ models
- Claude Tag — Anthropic's shared AI teammate
When to use this term: You're describing a shared agent in Slack that multiple people use together.
AI agent: software that acts on your behalf
An AI agent is software that uses AI to take actions—scheduling a meeting, sending an email, updating a Notion doc, booking a flight. It often has persistent memory and some level of autonomy (it can act without asking you every time).
Key attribute: Takes actions (not just answers questions).
Examples:
- OpenAI dots — "Always-on agents" with persistent memory
- Meta Muse — AI agent with background work and app actions
- Instinct — AI concierge you reach by text or email
- Lindy — "AI employee" with scheduled routines
When to use this term: You're describing software that takes actions (not just chats), or you want to emphasize autonomy.
AI assistant: a helper that answers on demand
An AI assistant is an AI helper that answers questions, summarizes content, or performs tasks when you ask. It's usually conversational (you type or speak, it responds). It's on-demand—it doesn't act autonomously or remember much between sessions (unless it's a newer "agent" like OpenAI dots).
Key attribute: On-demand—you ask, it answers.
Examples:
- ChatGPT (when used for Q&A, not as an agent)
- Siri, Alexa, Google Assistant
- Slack AI (search, summaries, recaps)
- Microsoft Copilot (when used for on-demand help)
When to use this term: You're describing a helper that answers questions or summarizes content (not a shared team tool).
Which term should you use?
- Use "AI coworker" when you're talking about a shared tool in Slack that your team directs together.
- Use "AI agent" when you want to emphasize actions (not just answers) or autonomy.
- Use "AI assistant" when you're describing a personal helper that answers on demand (like ChatGPT or Siri).
Many products blur the lines. OpenAI dots are both an agent (they take actions) and an assistant (they answer questions). Geniusly is both a coworker (shared in Slack) and an agent (it prepares work, though with human review). The categories aren't rigid—they're just useful shorthand.
Frequently asked questions
What's the difference between an AI coworker and an AI agent?
An AI coworker is a shared teammate in Slack that multiple people direct. An AI agent is software that takes actions on your behalf (can be personal or shared). Some AI coworkers are also agents (they take actions), but not all agents are coworkers (some are personal).
Is ChatGPT an AI assistant or an AI agent?
ChatGPT is usually called an AI assistant (it answers questions on demand). But OpenAI dots (ChatGPT's "always-on agents") are AI agents because they have persistent memory and can take actions.
Is Geniusly an AI coworker or an AI assistant?
Geniusly is an AI coworker—it's a shared agent in Slack that prepares work for your team. It's also technically an assistant (it helps you), but "coworker" better describes its team-focused design.
Which term do AI search engines prefer?
All three terms are common in search. "AI assistant" is the most generic. "AI agent" is trending in tech circles. "AI coworker" is newer and more specific to team tools like Geniusly, OpenTag, and Claude Tag.
