If you’re seeking the best value between Slack vs Teams, the latter stands out with its per-user fees and comprehensive feature set. Paid plans support large-scale meetings, cloud storage, and document sharing via Microsoft 365 apps, whereas Slack primarily focuses on team messaging and asynchronous collaboration.
A Teams subscription requires an annual commitment, but its monthly per-user fee is significantly cheaper than Slack. Over a year, Teams costs $48 per user, while Slack’s basic plan totals $87 annually.
In terms of free versions, Teams offers more flexibility with unlimited search history and hour-long video meetings with up to 100 participants. Slack, by contrast, supports audio meetings for 50 users and only retains the last 90 days of message history.
Best for Conference Calls: Microsoft Teams

Microsoft Teams clearly has the advantage when it comes to hosting conference calls because it essentially functions as a video meeting platform, compared to Slack.
Screen sharing, polling, and 5GB storage are included in Teams’ free version, while premium plans support meeting recordings, live translation, and whiteboarding. Slack, on the other hand, relies on a third-party app to record a conference call.

Beyond team messaging, Slack’s audio and video clips serve as time-saving tools that enable channel members to watch and listen to messages at their convenience. Its project management features let users automate routine tasks, utilize premade workflows, track project progress, and co-edit a company knowledge base.
While Teams offer similar capabilities, access to these tools typically involves a learning curve or a third-party app. Teams focuses on its office productivity suite where multiple users can seamlessly collaborate on documents, presentations, and spreadsheets.

Despite these differences, both Slack and Microsoft Teams support one-to-one and group messaging. Organize messages into different sections and follow conversations easily through message threading and formatting options, including italics, bold, and bulleted lists. For added interactivity, both solutions let you tag a user, use emojis, and send GIFs.
Best for Integrations: Slack
| Slack vs Microsoft Teams | | |

| Integration Rating Out of 5 | 5 out of 5 | 4.25 out of 5 |
| Number of Apps | ✓ | ✕ |
| Supported Apps on the Free Plan | 10 | ✕ |
| Number of Integrations | Up to 2,600 apps | Up to 2,400 apps including Microsoft 365 services |
Coming in at over 2,600 apps, Slack beats Microsoft Teams for third-party integrations. Subscribing to Slack’s free version includes access to ten integrations, while paid plans unlock unlimited access to thousands of apps. Microsoft Teams, on the other hand, requires a Microsoft 365 Business subscription to unlock its integrated apps and services.
Teams’ deep integration with Microsoft 365 products makes it an excellent fit for companies firmly embedded in the Microsoft ecosystem. With a Business Basic package, you get desktop versions of Outlook, Word, Excel, PowerPoint, Access, and Publisher, including access to other Microsoft services like SharePoint and Yammer.
For users who rely on Google-based apps, Slack is more suitable due to its pre-built integration with Google Workspace. This enables seamless access to Google Calendar, Meet, and Drive within Slack at no cost.

| Platform Structure | Message-first interface | Tab-based structure |
In terms of usability, Slack edges out Microsoft Teams as it takes a more personal and intuitive approach to its interface. Slack’s sidebar emphasizes channels, giving instant access to topics, message threads, and direct messages. It has more customization options, with the ability to organize the sidebar into different sections and pick from various color themes.

In contrast, Microsoft Teams is more complex and compartmentalized, with multiple tabs, teams, and channels. For corporate users, its streamlined design gives it a cleaner and more professional look compared to Slack. However, customization options are limited to themes, and inviting team members requires access to the admin portal. In Slack, you simply send an email invite to add a user.

Best for AI Capabilities: Slack

| Our Rating Out of 5 | 5 out of 5 | 4.38 out of 5 |
| AI Product | Slack AI | Microsoft CoPilot |
| Monthly Cost per User | $10 | $31.50 |
| In-app Assistance (bot) | ✓ | Requires a third-party bot app |
| AI-powered Search | ✓ | ✕ |
| Conversation Recaps | ✓ | ✓ |
Both platforms offer built-in generative AI capabilities but cater to different workflow needs. Slack AI is a strong choice for enhancing collaboration as it focuses on quick AI insights and task efficiency—all at an affordable price tag.
With AI-powered search, users can quickly browse shared files and public conversations to find relevant data. You can also schedule daily recaps and summarize long threads to keep up with the latest channel interactions.

Slack also includes a self-service chatbot that delivers reminders and automated messages to all users. It can be programmed for deadline notifications, knowledge base updates, and real-time alerts. The no-code automation tool can be used for sharing automated updates and generating onboarding processes.
Microsoft Copilot is tailored for enterprise collaboration and is built across Microsoft 365 apps. It can summarize meeting discussions, analyze visual data, and convert ideas into slideshow presentations.
However, Copilot misses the mark in terms of automation as it lacks a built-in workflow bot. Tech-savvy users only have two options: add bots via a third-party app or build a bot app using the Microsoft Bot Framework. While I appreciate Copilot’s comprehensive AI use cases, this can be overwhelming for teams that simply want to enhance task productivity.
