Knowledge management software centralizes an organization’s documentation and expertise so that everyone can access it. The choice depends on the use case: for team documentation, Notion, Slite, Nuclino, or ClickUp; for a corporate wiki, Confluence, Guru, Tettra, Bloomfire, or—within Microsoft 365— SharePoint; for customer support, Zendesk, Helpjuice, and Document360.
This comparison presents 12 knowledge base software programs: their uses, search and AI features, listed prices, and data hosting locations. The information was gathered on November 2, 2026, from the vendors’ websites.
Knowledge management software allows you to create, organize, search, and update written content, such as procedures, documentation, and answers to frequently asked questions. It provides a page editor, a search function, access controls, and—in most versions—an AI assistant that provides answers based on the content.
The internal knowledge base is used by teams for: the company wiki, project documentation, HR and IT procedures, and onboarding new employees. It is accessible only to employees, with access rights granted by team or by space. The customer knowledge base, or help center, is public: customers can find answers on their own, which reduces the number of support requests. This comparison focuses primarily on internal use and highlights tools designed for customer support.
A knowledge base is not an EDM system: an EDM system stores, organizes, and archives files, whereas a knowledge base contains pages written to be read and retrieved.
Atlassian’s Confluence is a knowledge-sharing platform featuring pages, spaces, role-based templates (HR, finance, marketing, IT), version history with the ability to revert to a previous version, and status markers that flag obsolete pages. Its AI, Rovo, adds search, chat, and writing assistance, and “brings together all knowledge across Confluence, Jira, Slack, and all enterprise applications.” A Rovo MCP server allows it to be queried from an external AI assistant. Atlassian reports “more than 300,000 customers” across all its products.

Zendesk Knowledge, formerly known as the Zendesk Help Center (San Francisco), is the knowledge base for its customer service suite: a self-service help center with generative answers in the search bar, available to both customers and employees (the “Employee Service” offering). The knowledge creator analyzes ticket history to generate an initial knowledge base; AI agents respond based on approved sources; a tool identifies gaps and outdated articles; and connectors integrate external content such as Google Drive, Confluence, SharePoint, or PDFs.

SharePoint, along with OneDrive, is the Microsoft 365 service that helps organizations “share and manage content, knowledge, and applications.” For a company already using Microsoft 365, its sites and pages can serve as an internal knowledge base, searchable via Microsoft Search. Agents in SharePoint help users find information within sites, pages, and document libraries; they are available with a Copilot license or on a pay-as-you-go basis. Viva Topics, Microsoft’s former knowledge management module, was discontinued on February 22, 2025: its pages have become standard SharePoint pages, and Microsoft now recommends SharePoint for publishing and organizing knowledge.
Price: Based on the Microsoft 365 subscription. Data: Within the Microsoft 365 EU Data Boundary, which covers EU and EFTA countries.
Limitations: Automatic page enrichment is no longer available since the removal of Viva Topics, and AI agents are subject to a dedicated license or pay-as-you-go billing.
A knowledge base is a space where an organization creates, organizes, and maintains its knowledge: procedures, documentation, and answers to frequently asked questions. Knowledge base software provides a page editor, search functionality, access control, and, increasingly, an AI assistant that provides answers based on the content.
The internal knowledge base is reserved for employees: company wiki, HR and IT procedures, project documentation, and onboarding for new hires. The external database, or help center, is public: customers can find answers on their own, which reduces the number of support requests. Confluence, Notion, Guru, Slite, Tettra, and Nuclino are designed for internal use; Zendesk, Helpjuice, and Document360 are primarily intended for customer use.
Yes. Notion has a Free plan; Confluence is free for life for up to 10 users; ClickUp offers a “Free Forever” plan; and Nuclino offers a Free plan limited to 50 items. Slite, Helpjuice, Zendesk, and Nuclino offer a 14-day trial, while Tettra offers a 30-day trial.
The prices listed per user per month on an annual billing basis are $5.78 for Confluence (Standard), €6 (excluding tax) for Nuclino (Starter), $8 for Tettra, $9 for ClickUp, €9.50 for Notion (Plus), and $10 for Slite (Basic). Zendesk charges per agent, at €55 per month for the Team Suite, and Helpjuice offers a flat rate of $249 per month for 30 users. Guru, Document360, and Bloomfire are available on a quote basis.
All the software programs in this comparison offer AI features: answers with source citations (Notion, Guru), search and chat (Rovo in Confluence), writing assistance (Document360, Helpjuice, Bloomfire), and content verification or updates (Guru, Slite, ClickUp). AI is included starting with the Standard plan at Confluence, but—outside of the trial period—is reserved for higher-tier plans at Notion and Nuclino (Business) and at Helpjuice (starting at $449 per month). Responses are based on content from the database and connected tools.
The two serve different purposes. An EDM (Electronic Document Management) system stores, organizes, and archives files (contracts, invoices, drawings), with approval workflows and retention periods. A knowledge base contains articles written to explain how to perform tasks and answer questions. The two often complement each other: the knowledge base links to reference documents stored in the EDM system or in SharePoint.
A knowledge base contains only what teams have entered into it. The documents themselves remain elsewhere: SharePoint, file servers, emails, and line-of-business applications. Outmind is a search engine and AI assistant that connects to these sources—including SharePoint and file servers—to find a document or an answer without having to migrate everything, while respecting each user’s access rights.
