Slack AI
AI-powered search and summarization built into Slack for teams drowning in messages
From $7.25/mo
What is Slack AI?
Slack was founded in 2013 and became the dominant team messaging platform, eventually acquired by Salesforce in 2021 for $27.7 billion. By 2025, Slack had over 200,000 paying customers and tens of millions of daily active users generating massive volumes of messages, threads, and shared files. Slack AI, launched in early 2024, addresses the inevitable consequence of that scale: information overload.
The core AI features target the daily pain of catching up on Slack. Channel summaries condense hours of messages into a few key points, letting you scan what happened overnight in a busy channel in 30 seconds. Thread summaries do the same for long discussions, surfacing the conclusion without requiring you to read 87 replies. AI search understands natural language — asking 'what did the product team decide about the API redesign?' returns a synthesized answer with source links rather than a list of keyword-matched messages.
Slack AI also integrates with Slack's Huddles (voice meetings), generating recaps and action items automatically after calls. The AI is available as a $10/user/mo add-on for Pro and Business+ plans, making the effective cost meaningful for large teams. For organizations where key decisions and institutional knowledge live in Slack rather than a knowledge base, the ROI on Slack AI is straightforward: hours of weekly catch-up compressed into minutes.

Frequently Asked Questions
- What does Slack AI do?
- Slack AI summarizes channels and threads, answers natural language search queries across your message history, generates recaps from Huddle voice calls, provides daily digest summaries of key activity, and helps draft messages. All features work directly inside your existing Slack workspace.
- How much does Slack AI cost?
- Slack AI is an add-on for $10/user/mo on Pro or Business+ plans. Pro starts at $7.25/user/mo, making the combined cost $17.25/user/mo minimum to access AI features.
- Does Slack have an affiliate program?
- Slack does not operate a public affiliate or commission-based referral program. Their partner ecosystem focuses on technology integrations and consulting partners rather than publisher affiliates.
- How does Slack AI compare to Microsoft Copilot in Teams?
- Both add AI summarization and search to team messaging. Microsoft Copilot in Teams is more deeply integrated with the Microsoft 365 ecosystem, offering connections to email, calendar, and Office documents. Slack AI is better for organizations already standardized on Slack, especially those using extensive Slack integrations and channels for cross-functional communication.
- Is Slack AI secure?
- Yes. Slack AI operates within Slack's existing security framework — your message data stays within your Slack workspace and is subject to the same encryption, data residency, and access controls as the rest of Slack. AI processing uses your data without training shared models on your conversations.
