The Most Popular and Effective Slack Wikis

The Most Popular and Effective Slack Wikis

Modern challenges require modern solutions. Digital technologies help us overcome the most difficult situations. Would you believe 10 years ago that working remotely could be as effective as working in the office? Today it is so. More and more companies, including small and large ones, are moving to a new working format. A lot of people prefer to work remotely and many employers support this new trend!

Such a transition of people from offices to remote work, without losing efficiency, became possible thanks to the development and implementation of special teamwork programs. Slack rightfully occupies a leading position in the segment. Today Slack is a convenient and effective task manager, which is already used by tens of millions of clients from all over the world, including large companies. Slack has a wide range of tools for organizing workflow and communication between team members.

It is worth highlighting a few points, which make the communication tool so effective and popular. First, there is a full-fledged free working version with an unlimited period. Of course, in order to take advantage of all the available features, you need to choose from several very affordable paid plans. Secondly, Slack has the ability to integrate with various applications, which complement its functionality.

One of these teamwork add-ons is wikis software, or simply wikis. We have tested various wikis for Slack and prepared the most effective and useful ones that really improve your remote work efficiency! Let’s take a closer look at them.

List of the most useful and effective Wikis for Slack

First, let’s answer the question: “What is wiki software?” In short, a collection of collaboration tools allows users to create and edit a variety of content through a single workspace. Since Slack has the ability to integrate third-party applications into its environment, you can install additional software, including wiki applications, which are tailored specifically for your industry. By adding Slack to an existing wiki project, you can access the entire knowledge base without leaving the conversation. This kind of integration greatly improves remote work, making your teamwork more efficient. We invite you to pay attention to the following Slack’s wikis.


Notion is an application for creating text documents, to-do lists, notes, databases, spreadsheets, kanban boards, etc. The software provides tools for project management and teamwork. The functionality allows you not to jump between the tabs of various services, and have everything you need in one place. Notion has a free plan, which is great for both personal use and beginner projects. Integration with Slack allows you to send changes and updates on any Notion page directly to the selected channel of the task manager. We use Notion internally at Clerk and love it.


Slicki is a popular Slack’s wiki software. Slicki integrates directly into Slack. It allows team members to work with information right in the Slack environment. What benefits will you get?

  • Easy access to information
  • Working with knowledge bases
  • Managing tasks using wiki pages
  • Create documentation based on posts in Slack channels
  • Simple rights management
  • Work on all devices, including gadgets and much more

It’s worth noting that Slicki has a 30 day free trial. During this time, you have access to all the features of the software. Be sure to give Slicki a try and decide whether to use paid mode or not.

Using Slack and looking for a wiki app? Pay attention to the simple, but at the same time effective and well-crafted software, known as SlimWiki.
