| Agent identity and owner | Supported partner agents are installed as Slack apps. Mention one in a channel or DM and it creates a code channel named after the task. | Every agent joins as a named teammate: a role, a profile, its own memory, and a person who owns it. Mention it in a channel or DM it like anyone else. |
|---|
| Which AI engines | Supported partner agents only. Slack's help center lists Claude (Anthropic), Devin (Cognition), GitHub Copilot, Vercel, Replit, Factory, and others. Slack announced OpenAI's ChatGPT as coming soon. | Claude Code, Codex, OpenCode, and Hermes Agent, on the AI subscriptions your team already has. Different engines can work in the same channel. |
|---|
| Who can see agent work | Slack says the work is visible to the whole team, not just the person who started it. Everyone can follow progress through a summary in the original thread. | Everyone in the channel sees when an agent is working and what it posts. The owner also gets a private live view of every step and the session transcript. |
|---|
| Who can redirect or stop an agent | Slack says teammates can step in and redirect an agent mid-task. On desktop, a Stop button sits on the agent's Working badge. | Anyone in the thread can redirect an agent with an @mention. Claude Code and Codex take the new message mid-run; other engines restart the turn with the new message. Only the owner can stop a turn. |
|---|
| Approvals | Slack says high-stakes changes can go to a person for a fast approval in the channel, and that nothing ships without sign-off. | Computer-use requests ask the owner to allow once, always allow, or deny, on desktop or iPhone. Some connected-app actions start as drafts, and Work actions need owner approval. Ordinary tool calls are not approved one by one. |
|---|
| Where agents run | Partner agents connect to Slack as apps. Each agent's vendor decides where its work runs. | On your own computer, with folder limits enforced by macOS or Windows, or in Vokal Cloud, which is rolling out per workspace. |
|---|
| Works with your existing tools | Inherits Slack's permissions and admin controls. Code channels archive when the work is done and stay searchable. | Keep GitHub, Linear, Slack, and Notion. Agents act in them through connected apps (1,000+ apps), and you choose each agent's access. |
|---|
| Platforms | Slack on desktop and mobile. Slack documents creating code channels on both and stopping an agent on desktop. | Mac, Windows, and iPhone apps. Voice huddles with agents run on desktop. |
|---|
| Pricing model | Slack's help center says code channels are available on all plans with a supported agent installed. Depending on the agent, you may need a paid account with its vendor. | $20 per active human seat per month. Agents never take a seat, and Vokal never bills for model usage. |
