7 Best Slack AI Agents for Teams (2026)

June 29, 2026Arthaud Mesnard

You searched "AI agent for Slack" and got forty results that all sound the same. Most of them are the same thing in different packaging: a chat box bolted into Slack that answers questions when you ask. A few are something else entirely: agents that read across your company's tools, take actions, and do the work.

This guide sorts them. It covers what to look for, ranks seven real options for 2026, and is honest about where each one wins and where it does not. Every pricing figure below was verified in June 2026; check the vendor's page before you buy, since plans change.

The picks at a glance

Best overall (AI coworker): Mio. Lives in Slack, reads and acts across 3,000+ tools, runs scheduled work, drafts proactively.
Best built-in: Slack AI. Native search, recaps, and summaries inside the Slack you already pay for.
Best for general Q&A: ChatGPT in Slack or Claude in Slack. A frontier model in your sidebar.
Best for customer and internal support: ClearFeed. Turns Slack channels into a real helpdesk.
Best for building custom agents: Lindy. A builder for teams that want to wire up their own workflows.

What to look for in a Slack AI agent

The category is noisy because "AI agent" is used for two very different things: assistants that chat and agents that act. Six criteria separate them.

Integrations breadth. Can it read and write across the tools where your work lives (HubSpot, Linear, Notion, Google Workspace), or only within Slack?
Memory and context. Does it remember your company and improve over time, or reset every conversation?
Scheduled and proactive work. Can it run recurring jobs and surface work on its own, or does it only respond when summoned?
Lives where you work. Is Slack the home, or a thin front end for a separate app?
Approval controls. Can you keep a human on sensitive actions before they happen?
Pricing transparency. Is the real cost clear, or buried in seat tiers and usage credits?

Reuse this checklist on any tool not in this list and the marketing sorts itself out fast.

1. Mio — best overall Slack AI coworker

Mio is a Slack-native AI coworker: an AI Chief of Staff that already knows your company. It lives entirely in Slack, reads context across your connected tools, proactively drafts the work, and takes actions with your approval. It is the option built around acting, not just answering.

Best for: Founders, small teams, and operators who want operational and reporting work off their plate.

Key features:

Lives entirely in Slack, in both channels and private DMs; no separate app to open.
Connects to 3,000+ tools, including HubSpot, Linear, Notion, Google Workspace, GitHub, and Stripe, with real read and write access.
Proactive: detects what needs doing (a brief is due, a meeting needs prep) and drafts it, instead of only acting when mentioned.
Scheduled work: runs recurring jobs like a weekly brief delivered to your DMs.
Learns your company over time and gets smarter every day.
Approval before sensitive actions; the human stays on every decision that matters.

Pricing: Free to start (early access phase as of June 2026).

Limitations: Slack-only by design, so it is not the pick for a Microsoft Teams shop. It is in early access, so the product is still expanding. It keeps a human on sensitive actions on purpose, so it is not a "fully autonomous, no oversight" tool, which is the point.

A few things you can hand it:

@Mio every Monday at 8am, DM me my brief: what shipped in Linear,
deals that moved in HubSpot, and the top three things that need
my decision today, with sources linked

@Mio before each external meeting tomorrow, pull the HubSpot
history, recent emails, and related Slack threads, and post a
one-page prep the night before

@Mio every Friday at 4pm, draft the weekly company update from
what shipped, key metrics, and decisions in #leadership, and
post it in my DM for review before it goes out

2. Slack AI — best built-in option

Slack AI is Slack's own native AI feature set: channel and thread recaps, AI-powered search across your workspace, and "catch me up" summaries. It is the lowest-friction option because it is already inside the Slack your team uses, with no new vendor to add.

Best for: Teams that want summarization and search without adding a tool.

Key features:

Native channel summaries, thread recaps, and "catch me up" digests.
AI search across your Slack history.
Zero setup beyond enabling it on your plan.

Pricing: Part of paid Slack plans (verify current packaging with Slack, as of June 2026).

Limitations: It works inside Slack's own data, not across your other tools, so it summarizes and searches but does not act on HubSpot or Linear. It is reactive: it answers, it does not own recurring work.

3. ChatGPT in Slack — best for general Q&A

ChatGPT has an official Slack app: mention it in a channel or DM it and you get the same model your team uses in a browser, now in your sidebar. It is excellent for drafting, brainstorming, and one-off questions without leaving Slack.

Best for: Teams that want a strong general-purpose model inside Slack.

Key features:

A frontier model available by @mention or DM in Slack.
Strong at drafting, rewriting, summarizing pasted content, and general reasoning.
Familiar to anyone who already uses ChatGPT.

Pricing: Tied to ChatGPT plans (verify current Slack app availability and tiers with OpenAI, as of June 2026).

Limitations: It is an assistant, not a coworker. It does not have standing access to your company's tools, does not remember your business across sessions by default, and does not run scheduled or proactive work. You drive every task.

4. Claude in Slack — best for long-context work

Claude, Anthropic's assistant, is available in Slack through its official integration. It is particularly strong on long-context tasks: pasting in a long document, comparing two policy drafts, or working through a dense thread.

Best for: Teams doing heavy document and long-context reasoning in Slack.

Key features:

Anthropic's model by @mention or DM in Slack.
Excellent long-context handling for large documents and comparisons.
Clean, careful writing and reasoning.

Pricing: Tied to Claude plans (verify current Slack integration and tiers with Anthropic, as of June 2026).

Limitations: Like ChatGPT in Slack, it is an assistant. No standing tool access, no persistent company memory by default, no proactive or scheduled work. It responds; it does not own the job.

5. Viktor — AI coworker for Slack and Teams

Viktor is an AI coworker that lives in Slack or Microsoft Teams and connects to a wide set of business tools with read and write access. It is one of the genuine action-taking agents in the category, positioned around autonomous execution across your stack.

Best for: Teams, including Microsoft Teams shops, that want an execution-focused AI coworker.

Key features:

Lives in Slack or Microsoft Teams.
Connects to 3,000+ business tools with real read/write access (per Viktor's site, June 2026).
Positioned as an autonomous coworker that executes across tools.

Pricing: Not publicly verified as of June 2026; check Viktor's site.

Limitations: The execution-first framing is a different emphasis from a proactive draft-for-approval model; if you want a human reviewing before action by default, confirm how its controls work. Pricing is not transparent at the time of writing.

6. ClearFeed — best for support in Slack

ClearFeed turns Slack channels into a real helpdesk. Customer or employee messages become tickets, AI suggests replies from your knowledge base, and unresolved threads get routed, tracked, and held to SLAs. It is the specialist pick for support, not a general coworker.

Best for: Teams running customer or internal support through Slack.

Key features:

Converts Slack messages into tracked tickets with SLAs.
AI-suggested replies from your internal knowledge base.
Two-way sync to systems like Zendesk, Salesforce, HubSpot, and Jira.
Covers both external (customer) and internal (IT, HR, finance) support.

Pricing: From $24 per agent per month, or usage-based from $40 per month for 10 channels and 100 tickets; 14-day free trial (ClearFeed pricing, June 2026).

Limitations: It is purpose-built for support workflows, so it is not the tool for revenue reporting, briefs, or general operations. Outside support, you would pair it with something else.

7. Lindy — best for building custom agents

Lindy is an AI agent builder. You assemble agents that connect to Slack and your other tools, then @mention or DM them to run workflows you have designed. It suits teams that want to wire up bespoke automations rather than adopt a coworker that arrives pre-shaped.

Best for: Teams that want to build and own custom agent workflows.

Key features:

Visual builder for custom agents across Slack and connected tools.
Inbox management, meeting recording, and calendar automation in the base feature set.
Flexible if you are willing to design and maintain the workflows.

Pricing: Plus $49.99/month, Pro $99.99/month, Max $199.99/month, plus a credit-based usage system; 7-day free trial, no permanent free tier (Lindy pricing, June 2026).

Limitations: It is a builder, so the burden of designing, testing, and maintaining workflows is on you. The credit system means real costs can exceed the base plan depending on usage. It is closer to a platform than a teammate you simply brief.

FAQ

What is the best AI agent for Slack?

For most teams that want an AI that actually does the work rather than just answering questions, the best Slack AI agent is an AI coworker like Mio: it lives in Slack, reads and acts across 3,000+ tools, runs scheduled work, and drafts proactively with your approval. If you only need summaries and search, Slack AI is the lowest-friction start. The right pick depends on whether you want an assistant that chats or an agent that acts.

What is the difference between Slack AI and an AI agent for Slack?

Slack AI is Slack's native feature set: it summarizes channels and threads and searches your workspace. An AI agent for Slack, especially an AI coworker, goes further: it reads and writes across your other tools, runs recurring jobs, and takes actions with approval. Slack AI helps you understand what happened in Slack; an AI coworker does work across your whole stack.

Are there free AI agents for Slack?

Slack AI is included in paid Slack plans, and Mio is free to start in its early access phase as of June 2026. ChatGPT and Claude have free tiers in general, though Slack app availability and limits vary by plan. Most action-taking agents charge once you move past basic usage.

Is Mio better than other Slack AI agents?

Mio is the strongest pick when you want a proactive AI coworker that lives in Slack, acts across your tools, and keeps a human on sensitive actions. It is not the right pick if you are on Microsoft Teams (consider Viktor) or if your only need is support ticketing (consider ClearFeed). "Better" depends on whether you want a coworker that owns work or an assistant that answers.

Why this matters now

Slack's own 2026 research found that while 40% of desk workers have used an AI chatbot, only 23% have actually directed one to complete work on their behalf. That gap is the whole story of this category: most "Slack AI agents" are assistants people chat with, not coworkers that do the job.

The tools worth adopting in 2026 are the ones that close that gap: that live where you work, read across your tools, and own recurring work with a human on the decisions. Mio is built exactly for that. Try it free at app.mio.xyz.
