Top 6 Slack Wiki Platforms in 2025

What is Slack wiki

A corporate wiki accessible in Slack is known as Slack Wiki. It enables users to access your company’s internal information database from within your Slack.

Why your company needs a Slack wiki

Organizations capture information around their business in a central knowledge portal. When employees have requests or queries, Slack wiki helps them to solve that faster, they have to context switch from their core work, understand the organization of information in the knowledge portal, and optimally search for the information they are looking for.
