What Is Slack? (Explained for Beginners)

Slack is a business messaging application that helps teams communicate and collaborate in real-time. Think of it as a smarter, faster alternative to email, designed for modern and remote team collaboration.

Slack goes beyond simple chat by organizing conversations into channels for specific teams, topics, or projects. It keeps discussions clean using threads and offers built-in tools for file sharing, search, and custom workflows.

With over 42 million daily active users (and expected to hit 48 million by the end of 2025), Slack has firmly established itself as the central hub for modern work. It’s used by nearly 80% of the Fortune 100 and integrates seamlessly with over 2,600 tools, from Google Drive to Zoom.

That’s why AI chatbots belong in Slack. They automate tasks and instantly provide information where work is happening, enhancing productivity within the platform.

What Are AI Chatbots for Slack?

AI chatbots for Slack are virtual assistants that streamline your workflow. They handle routine tasks, answer FAQs, and provide instant access to information, freeing up your team for more complex work. These chatbots can:

  • Answer FAQs across teams

  • Summarize threads and channels

  • Search internal documents and knowledge bases

  • Automate repetitive tasks

  • Integrate with CRMs to pull up customer records

There are two main types of Slack bots:

  • Built-in Slack AI bots: Limited to searching and summarizing data within your workspace, offering passive assistance.

  • Third-party Slack bots (e.g. Wonderchat): Trained on company documents and wikis, integrating with CRMs and external tools. They provide active, specialized support and can perform tasks across your entire workflow.

Why Use Third-Party AI Chatbots in Slack?  

Here’s why many teams choose tools like Wonderchat over Slack’s native AI features:

Works with Your Content

Your chatbot can be trained on company wikis, SOPs, help docs, PDFs, and website content. This ensures that when a question arises in Slack, your AI provides accurate, company-specific answers.

Fast, 24/7 Support

With AI chatbots, your team gets instant responses anytime. No more waiting or repeatedly tagging colleagues for answers.

Easier than Training Staff

Instead of hunting down information, employees simply ask the Slack chatbot, which delivers answers in seconds.

Saves Time

Knowledge workers spend a great deal of their time searching for information. AI chatbots help reduce this, freeing up valuable time for more important tasks.

Seamless integration

Unlike Slack's native AI, third-party bots like WonderChat integrate with external tools and databases. This enables your chatbot to take action beyond the workspace, optimizing workflows across the board.
