AI Chatbot for Slack: 8 Best Bots & AI Agents Compared (2026)

Slack is where teams collaborate: conversations, decisions, files and daily standups. Bringing AI into Slack means people get answers, summaries and drafts where they already work, without switching tabs.

The options now split into two groups. AI chatbots answer questions and draft text from a general model. AI agents go further: they search your company's documents, wikis, drives and tickets, respect who is allowed to see what, and sometimes take actions. We compared the 8 best AI chatbots and agents for Slack in 2026, free and paid, so you can match the tool to the job.

What Makes a Good Slack AI Chatbot?

These are the criteria we used for each tool:

• Ease of setup -- how quickly can you go from zero to a working AI bot in Slack?
• AI model choice -- can you pick Claude, ChatGPT, Gemini or a local model, or is the model fixed by the vendor?
• Company knowledge -- can it answer from your documents, wikis, drives and tickets, and does it enforce each person's permissions?
• Privacy and control -- where is your data processed, and what admin controls and logs exist?
• Pricing -- is there a free option, and what do paid plans cost?
• Reach beyond Slack -- does it also work on WhatsApp, Telegram, Discord or Microsoft Teams?

How We Chose

For the September 2026 refresh we checked each vendor's own pricing page, help center and announcement posts (linked in each entry) and removed any price or feature we could not confirm. The order reflects fit for the broadest range of teams, from free-to-start bots to enterprise agents. OpenClaw Easy is our own product; we say so wherever it appears and list what it does not do.

The 8 Best AI Chatbots and Agents for Slack in 2026

1. OpenClaw Easy

OpenClaw Easy is a free desktop app for macOS 12+ and Windows 10/11 (current version 2026.10.1) that runs the open-source OpenClaw runtime and connects it to Slack and other messaging apps. It supports Claude, ChatGPT, Gemini and local models via Ollama: bring your own API key, use pre-paid credits, or run a local model. The app runs on your computer and talks to Slack over Socket Mode, so there is no webhook server to host. With a cloud model, message text goes to the AI provider you pick; with Ollama it stays on your machine.

What sets OpenClaw Easy apart is multi-channel support: the same app connects Slack, WhatsApp, Telegram, Discord, Feishu and LINE. You configure the model and system prompt once and the assistant answers everywhere. It is a general assistant, not a company knowledge index; see what it does and does not do with company data.

Getting started takes about ten minutes, most of it creating the Slack app:

Best for: individuals and small teams who want a free Slack AI bot they run themselves, with a choice of models and the same assistant on other messaging apps.

2. Slack AI and Slackbot (by Salesforce)

Slack's built-in AI needs no separate install. After Slack's June 2025 plan changes, Pro includes AI conversation summaries and huddle notes, and Business+ ($15 per user per month billed annually, $18 monthly) adds AI search answers, recaps, translation, workflow generation and Slackbot, Slack's AI agent. Slack's AI features guide lists Slackbot for Business+ and Enterprise+, with a limited preview on Free and Pro.

Enterprise+ (contact sales) adds enterprise search, which brings content from connected apps such as Salesforce, Google Drive, Confluence Cloud, Jira Cloud, GitHub, SharePoint, OneDrive, Asana and Box into search, AI answers and Slackbot, and only shows content the person searching has permission to access. The limits: it works inside Slack only, and Slack's plan documentation does not offer a choice of underlying model.

Best for: teams already on Slack Business+ or Enterprise+ who want AI summaries, search answers and an agent without adding a vendor.

3. Claude Tag (Anthropic's Claude in Slack)

Anthropic launched Claude Tag on June 23, 2026, in beta for Claude Team and Enterprise customers. Admins grant Claude access to selected Slack channels and connect the tools and data they choose; anyone in those channels can then tag @Claude to delegate a task, and Claude remembers relevant context from the channels it is in. Access is scoped per channel, admins can cap token spend for the organization and for individual channels, and a log shows everything Claude did and who asked.

According to Slack's help center, Claude Tag replaced the previous Claude app in Slack starting August 3, 2026; that earlier app required a paid Claude Pro, Max, Team or Enterprise account.

Best for: teams on Claude Team or Enterprise who want an agent teammate in shared channels, connected to company tools with admin controls.

4. ChatGPT app for Slack (OpenAI)

OpenAI's ChatGPT app for Slack requires a ChatGPT Plus, Pro, Business, Enterprise or Edu account. It gives you a one-on-one ChatGPT chat in a Slack sidebar where you can ask questions, turn long threads into action items, draft replies and search messages and files you already have access to. Keyword search works on any Slack plan; search by meaning needs Slack AI search enabled on Business+ or Enterprise+. On Enterprise and Edu workspaces, ChatGPT admins control who can use the app.

Best for: teams already paying for ChatGPT who want it inside Slack for personal drafting, summaries and search.

5. Glean

Glean is an enterprise AI search and assistant platform built around 100+ connectors (Jira, GitHub, Salesforce, Confluence and more) with permissions enforced. In Slack, its Glean bot returns search results via /glean and can be enabled to answer questions posted in channels, with each answer personalized to the asking user's content permissions. It does not respond in channels shared with external organizations, and it only answers users who have Glean Assistant access.

Glean does not publish pricing; contracts are quoted by sales.

Best for: larger companies that want one permission-aware "ask anything about our company" assistant inside Slack and have budget for an enterprise contract.

6. Workato (Genies and Workbot)

Workato is an enterprise automation platform. Workbot is its long-standing Slack bot for running automations, and Workato Genies are its prebuilt AI agents for functions such as IT, HR, sales and support. Genies now run natively in Slack channels: Help Desk Mode answers every message in selected channels, On-Mention Mode answers only when tagged, Genies read full thread context, and actions can require a Workato Identity login so the right person confirms each one.

Workato uses usage-based pricing quoted through sales, and Genies are available on specific plans.

Best for: enterprises that want Slack help-desk agents which do not just answer but also act across business systems.

7. ChatBot.com

ChatBot.com is a no-code chatbot builder with a Slack integration: add a bot to one or more channels, call it with an @mention, and it always replies in a thread. Bots are built with a drag-and-drop builder and templates, and can pull data from connected databases and CRMs.

Current pricing: Essential is $19 per user per month billed annually ($25 monthly) with 10 AI resolutions a month; Growth is $79 per user per month billed annually ($99 monthly) with 200; Enterprise is custom. The pricing page does not say which plans include the Slack integration, so confirm before buying.

Best for: teams that want structured, no-code bot flows in Slack rather than open-ended chat.

8. Botpress

Botpress is a developer-oriented platform for building AI agents. Its official Slack integration is installed from the Botpress Hub and authorized with Slack, or configured with your own Slack app, after which workspace members can chat with the bot. You design the agent's logic and knowledge yourself.

Botpress changed its pricing for new workspaces in May 2026; check the current pricing page, since existing workspaces kept their previous plans.

Best for: developers who want full control over a custom agent and are comfortable building it.

Quick Comparison Table

AI Agents for Slack That Answer Business Questions From Company Data

A growing share of searches ask for something more specific than a chatbot: an AI agent inside Slack that answers business questions such as "what did we agree with this customer?" or "what is our refund policy?" from the company's own documents, wikis, drives and tickets. A general model cannot do that on its own. The capability needs four things.

• Connectors and retrieval -- the agent must index or query the systems where knowledge lives (Google Drive, Confluence, Jira, Salesforce, SharePoint and so on), keep that index fresh, and ideally cite the source it answered from.
• Permission-aware answers -- every answer should come only from content the person asking is allowed to open. Without this, a Slack bot becomes a way around document permissions: an intern could ask a question and get an answer drawn from a board deck.
• Admin controls and audit -- control over which channels and people can use the agent, which data each deployment can reach, spend limits, and a log of what it did.
• Data residency and retention -- know where the index, prompts and answers are stored and processed, and whether that matches your regulatory obligations. Ask each vendor directly; this varies by plan and region.

Which of the ranked tools actually do it

• Slack enterprise search (Enterprise+) -- yes. Connectors include Salesforce, Google Drive, Microsoft Teams, Confluence Cloud, GitHub, Jira Cloud, OneDrive, SharePoint, Asana and Box, and Slack says results, AI answers and Slackbot responses only include content the searcher may access. Org Owners or Admins turn it on. Business+ AI search answers cover Slack conversations and shared files, not other apps.
• Glean -- yes, and it is the most connector-rich option here. 100+ connectors, answers in Slack channels personalized to each user's permissions, and no answers in channels shared with external organizations.
• Claude Tag -- yes, within what admins connect. Data access and tools are scoped per channel, with spend limits and an activity log. It is still in beta.
• Workato Genies -- yes for task-focused agents. They work across connected business systems and can take actions that require the requesting user to authenticate.
• ChatGPT app for Slack -- partly. Inside Slack it searches Slack messages and files the user can already access; it is not documented as a channel-wide company knowledge bot for other apps.
• ChatBot.com and Botpress -- only what you build. You supply the knowledge and integrations; we did not find per-user document permission enforcement documented for their Slack bots, so do not assume it.

What OpenClaw Easy does and does not do here

OpenClaw Easy is honest about this one: it is not a permission-aware enterprise knowledge agent.

• What it does: it runs one AI agent on your computer that can search Markdown memory files in its workspace, call tools you add through MCP servers, plugins or skills from ClawHub (web search, for example), and answer in Slack with the model you choose. With a local Ollama model, the processing stays on your machine. You decide who may message the bot under Access.
• What it does not do: it does not ship managed connectors that index Google Drive, Confluence, Notion or Jira, and it does not check each Slack user's document permissions. Anything you give the agent is available to everyone allowed to message it. It also runs on one computer, which has to be on and online for the bot to answer.

Our recommendation: if you need company-wide answers with permissions enforced, choose Glean, Slack Enterprise+ enterprise search or Claude Tag. OpenClaw Easy fits small teams that want an assistant for general questions, drafting and a curated set of documents that everyone in the channel may see anyway.

Frequently Asked Questions

What is the best AI agent for Slack that answers business questions using company data?

For company-wide answers drawn from documents, wikis, drives and tickets, the verified options are Glean, Slack's own enterprise search on the Enterprise+ plan, and Anthropic's Claude Tag. Glean connects to 100+ apps and its Slack bot tailors each answer to the asking user's content permissions. Slack enterprise search pulls in apps such as Google Drive, Confluence Cloud, Jira Cloud, Salesforce and SharePoint and only returns content the searcher may access. Claude Tag, in beta for Claude Team and Enterprise, lets admins connect chosen tools and data per channel with spend limits and an activity log. For IT or HR help desks that also take actions, Workato Genies run in Slack channels.

Can a Slack AI bot answer questions from Google Drive, Confluence or Jira?

Yes, but only tools with connectors do it. Slack enterprise search (Enterprise+ plan) connects Google Drive, Confluence Cloud, Jira Cloud, GitHub, Salesforce, SharePoint, OneDrive, Asana, Box and Microsoft Teams. Glean indexes 100+ apps and answers in Slack. Claude Tag uses whichever tools and data an admin connects. A general chatbot such as OpenClaw Easy does not ship Drive, Confluence or Jira connectors; it can search Markdown files you place in its workspace and call tools you add through MCP servers or skills, but that is not a managed, permission-aware company index.

Does a Slack AI agent respect document permissions?

Only if it is built to. Slack says enterprise search results, AI answers and Slackbot responses include only content the person asking is allowed to see, and Glean personalizes answers to each user's content permissions and does not answer in channels shared with external organizations. Claude Tag scopes data access per channel set by admins. A single-identity bot works differently: whatever documents or tools you give it are available to everyone allowed to message it. That includes OpenClaw Easy, so only give it material every permitted sender may see.

Is OpenClaw Easy free for Slack?

Yes. OpenClaw Easy is free to download and use on macOS 12+ and Windows 10/11. You bring your own API key from Anthropic, OpenAI or Google and pay only that provider's per-token rates, run a local Ollama model for no model cost, or buy pre-paid credits in the app. There are no per-message fees and no subscription for the core app.

Can I use ChatGPT in Slack?

Yes. OpenAI's official ChatGPT app for Slack works with ChatGPT Plus, Pro, Business, Enterprise or Edu accounts and gives you a one-on-one ChatGPT chat in the Slack sidebar for questions, thread summaries, drafts and searching Slack messages and files you can already access. If you would rather run a bot with an OpenAI API key and switch to Claude, Gemini or a local model later, OpenClaw Easy does that without changing the Slack app.

Which is the most private Slack AI bot?

OpenClaw Easy with a local Ollama model keeps AI processing on your own computer: the bot receives Slack messages over Socket Mode and the model runs locally, so no AI provider sees the text. Slack itself still stores the messages as usual. With a cloud model, message text is sent to the provider you choose.

Can I add AI to Slack and WhatsApp at the same time?

Yes. OpenClaw Easy connects Slack, WhatsApp, Telegram, Discord, Feishu and LINE from the same app. You set up the model and system prompt once and the assistant answers on every connected channel.

What is the cheapest AI bot for Slack?

OpenClaw Easy with a local Ollama model costs $0 in software and model fees; you only supply the computer. With a cloud API key you pay the provider's per-token rates. Among first-party Slack plans, Pro includes AI conversation summaries and huddle notes, and Business+ at $15 per user per month (billed annually) adds AI search answers, recaps and Slackbot.

Does Slack AI use ChatGPT?

Slack does not sell its built-in AI as ChatGPT, and its plan documentation does not offer a choice of underlying model. If you want ChatGPT specifically inside Slack, install OpenAI's ChatGPT app for Slack (requires a paid ChatGPT plan) or run OpenClaw Easy with an OpenAI API key.

Is Slack AI worth it in 2026?

It is worth it if your team lives in Slack and wants built-in help. Since Slack's June 2025 plan changes, Pro includes AI summaries and huddle notes, Business+ ($15 per user per month billed annually, $18 monthly) adds AI search answers, recaps, translation and Slackbot, and Enterprise+ adds enterprise search across connected apps. It only works inside Slack, so teams that also want AI on WhatsApp or Telegram, or a model of their choosing, often add a separate bot.

How do AI Slack bots work under the hood?

Slack bots receive events in one of two ways: the Events API, which needs a public HTTPS endpoint for Slack to push to, or Socket Mode, which uses an outbound WebSocket from the bot to Slack. OpenClaw Easy uses Socket Mode, so it works on a laptop behind a NAT with no webhook server. On each message the bot sends the text plus your system prompt to the AI model, then posts the reply through Slack's Web API.

Can I use Claude in Slack?

Yes, two ways. Anthropic's Claude Tag, which replaced the Claude app in Slack starting August 3, 2026, is in beta for Claude Team and Enterprise customers and lets people in enabled channels tag @Claude to delegate tasks. Or run OpenClaw Easy with a Claude API key: the app is free, you pay Anthropic's per-token API rates, and you can switch models later without rebuilding the Slack app.
