18 Best Slack Bots for a Smarter Workspace in 2025
Slack has become the central hub for communication in many workplaces. It’s where teams share updates, ask questions, track progress, and make decisions.
As valuable as this flow of conversation is, it can also become hard to manage. When too many threads go unanswered or important updates get overlooked, the flow of work slows down.
But what makes Slack even more helpful are the bots you can add to it. These bots help manage tasks, organize meetings, respond to questions, and even connect with the chatbot on your website.
The best Slack bots are built to solve everyday problems in a way that fits right into how your team already works.
In this guide, we’ll cover the most useful Slack bots for different roles and workflows. You’ll see how these bots can improve communication and help your team stay focused.
What Are Slack Bots and How Do They Work?
If you are using Slack to manage business communication, you already understand how valuable it is for staying organized. Slack makes it easier to automate routine tasks, centralize updates, and improve the way your team works together.
Slack bot is a program that connects to your Slack workspace. It listens for specific commands, messages, or events, and then responds with actions or replies.

These bots can be used to assign tasks, send reminders, tag reviews, create polls, or respond to frequently asked questions. Many of them also integrate with other tools your business already uses, such as Google Drive, Trello, Salesforce, or project management platforms.
Two Types of Slack Bots
When deciding how to use bots in your Slack environment, you will generally choose between two categories:
Pre-Built Slack Bots
These bots are available from the Slack App Directory. They are designed to solve specific problems such as daily standup meetings, time tracking, task assignments, and meeting reminders.
You can install these bots with just a few clicks and begin using them with minimal setup. If your goal is to get started quickly with little technical effort, pre-built bots are usually the best place to begin.
Custom Slack Bots
If you have specialized needs, custom bots are a great option. These are built using development tools like Node.js or Python and connected to Slack using Slack’s API.
With a customized chatbot, you have more flexibility. You can design one that fits your internal workflows, connects to your CRM or helpdesk, or performs tasks based on logic that fits your team structure.
This is an ideal choice for small teams or companies with in-house development resources.
18 Best Slack Bots by Use Case
Now that you know what features to look for, it's time to focus on real bots you can use in your Slack workspace. Below are groups of Slack bots organized by business use case.

12. GitHub
GitHub’s official Slack app brings version control updates into chat. Teams can subscribe to repository activity so that new commits, pull requests, issues, and code reviews are posted to Slack channels.
The integration also expands GitHub links with rich details, such as showing PR titles, diffs, or issue details to give context in Slack.
Developers can take action via Slack, like using Slack slash commands to open or close GitHub issues, and being notified to review a PR.
Slack Bots for HR and People Operations
Managing a team involves more than just day-to-day communication. You also need to handle access requests, time-off tracking, and gathering employee feedback. These Slack bots are built to support HR tasks and lighten the load for managers.
13. Workleap Officevibe
Officevibe is an engagement and review platform, and its Slack integration helps gather and act on employee input. The bot sends automated weekly pulse surveys to team members via Slack, where they can anonymously share how they feel about work.

18. Denser
Denser is an AI-powered chatbot platform that bridges your website’s chat with Slack. It routes web inquiries into Slack channels and supports live replies to help the entire team stay on the same page.
When a visitor asks your site’s chatbot a question, the query can be routed to Slack with AI-generated suggestions. Your support agents can reply in Slack, which then sends the response back to the website chat.
A mix of live chat support and Slack integration helps your business maintain fast response times while keeping everything inside one workspace.
How Slack Bots Fit Into Your Business Workflow
Once added, Slack bots operate based on specific triggers. A trigger could be a keyword, a quick slash command, a mention, or an event like a new task being created in your project tracker.
When the trigger occurs, the bot responds according to its setup. Here are a few ways you can use bots in your workspace:
- Schedule task reminders so team members do not miss deadlines
- Create daily check-in messages for teams on remote work
- Post real-time updates from external tools like GitHub Actions or Jira
- Answer routine employee questions about leave balances or HR processes
- Provide quick access to knowledge base articles
- Support your website's live chat tool by connecting external inquiries to a specific channel
If you already use a website chatbot to handle visitor questions, a Slack bot can help by sending those messages straight into a support channel. It gives your team faster access to leads or issues without logging into other platforms.
Tools like Denser make this possible with integrations that support real-time messaging, simple workflows, and automated handoffs between website bots and Slack.
Instead of adding other apps and dashboards to check, you keep everything within Slack, where your team already spends their time.

Essential Features to Look for in Slack Apps for Bots
It’s important to know what capabilities to look for so you can pick the ones that support your business goals. Below are the features that matter most when choosing the best Slack apps to create bots.
Easy Setup and Configuration
You should be able to install a Slack bot without going through complex steps or needing help from a developer.
Therefore, you need to look for bots that provide a simple setup flow and guide you through settings such as selecting channels, permissions, and bot commands.
Most bots from Slack's directory already meet this standard. Still, it’s smart to double-check for setup instructions or reviews from other teams before installing.
Task Automation and Workflow Support
An intuitive Slack bot helps your team do more with less effort. It should automate routine tasks like reminding your team about due dates or assigning tasks to team members.
Denser offers workflow automation that connects your website chatbot to your team. If someone asks a question through your site, Denser routes the inquiry to a specific channel, where your support team can reply fast.
This allows you to manage live support in real time with less context switching.
AI and Chat Capabilities
Some of the most helpful Slack bots use artificial intelligence to improve team communication. These bots can respond to common questions, learn patterns in team behavior, or guide new employees through onboarding steps.
AI-powered bots can adjust replies based on the situation, which makes them useful for B2B organizations, customer service, or internal search purposes.
Denser’s AI chatbot can do this across your website and Slack. For example, you can install a Denserbot to manage customer messages on your site, and use a Slack bot to continue the conversation internally.
Integration With Existing Tools
If your Slack bot does not work with your existing tools, it’s just another app to manage.
You have to look for bots that can connect with project management platforms, customer service tools, CRMs, calendars, and documentation hubs. The more the bot can connect to the systems you already depend on, the more useful it becomes.
Control and Permissions
Bots operate in the same space where your team shares important messages. For that reason, you need to control what they can see and do.
You need to choose bots that let you set which channels they work in, who can use them, and what kind of data they access. This is important for bots handling customer messages, code comments, or anything related to personal or business-sensitive information.
Good permission settings make the bot safer to use and easier to trust. Your Slack workspace stays organized, and your team can use the bot with confidence.
Using Denser to Power Your Slack Workspace
If your team regularly turns to Slack for answers, updates, or support, you know how easy it is for messages to be missed in the flow of conversation.
Aside from being a smart website chatbot, Denserbot also works inside the Slack ecosystem to help your team get fast, accurate answers pulled from your existing knowledge base.
Your team can ask for help, look up documentation, or check company processes simply by mentioning @DenserAI in any Slack channel.
The response appears as a threaded reply, which keeps your channels clean and organized while giving everyone fast access to reliable information.
With minimal setup, Denser bridges your content and your team. And with Zapier, you can automate workflows from message to answer. It’s a simple way to bring intelligent document search and AI support into your everyday Slack conversations.
How to Set Up Slack Bot With Denser
Adding a chatbot that responds right inside your workspace can make things faster for your teams.
With Denser’s integration, you can connect your chatbot to Slack and create an experience where questions are answered in real time.
Here’s a simple guide to setting up Denser with Slack using Zapier.
Step #1: Configure Your Slack Trigger
Start by choosing which Slack channel you want Denser to monitor. Go to Zapier and set up a new workflow (called a Zap).
Under the “App & Event” tab, select Slack as your trigger app. Then choose the event “New Message Posted to Channel.”
From there, select the specific Slack channel where Denser should listen for incoming messages. This is the space where your whole team will mention the chatbot and expect answers.
Step #2: Set DenserAI as the Action
After the Slack trigger is set up, it’s time to add DenserAI as the action step. In Zapier, choose Denser from the app list and select “Process Input Text” as the event.
To complete this step, you’ll need your chatbot ID and REST Access Key from your Denser account. Once entered, map the Slack message text to the chatbot’s input field so it knows what to respond to.
This step allows the chatbot to take your team’s questions from Slack and process them using your connected knowledge base.
Step #3: Set Slack as the Output Action
After Denser returns a response, you want that answer sent back into the same Slack channel. Add another action step in Zapier and choose Slack again.
Select “Send Channel Message” as the event. Set the Slack channel to the same one used in the trigger step. For the message content, insert the answer provided by Denser.
Make sure to toggle “Send as a bot?” to Yes so the message appears to be coming from your integrated chatbot.
Step #4: Publish the Workflow
Once all steps are complete, publish the Zap to activate the integration. From this point forward, whenever a message is posted in your selected Slack channel, Denser will process it and send a response into the same conversation thread.
This setup creates a real-time connection between your Slack workspace and your AI chatbot, allowing your team to ask questions and receive notifications.
It’s beneficial for internal support, onboarding, sales teams, or any group that depends on fast, reliable access to shared knowledge.
