Most companies already have the information that belongs in an internal wiki. The problem is that it is often scattered across tools. Policies may live in Google Drive, processes in old documents, technical knowledge in GitHub, and day-to-day answers in Slack or Teams.
An internal wiki brings that information into one shared place where employees can find it, update it, and connect related knowledge. It can be as simple as a company handbook or as broad as the main knowledge system for the whole organization.
This guide explains what an internal wiki is, shows common and real-world examples, compares internal wiki software, and covers how to build and maintain one.
What is an internal wiki?
An internal wiki is a private, shared workspace where employees create, organize, and maintain company knowledge. It gives people one place to find the information they need to do their work and understand how the company operates.
A company wiki is created, extended, and maintained collaboratively by the employees themselves. It acts as your team's single source of truth – you can think of it as your company's own internal Wikipedia. As your team and your business grow, an internal wiki can become one of your most valuable assets.
An example of an internal company wiki created in Nuclino
You may also see the terms company wiki, corporate wiki, team wiki, or internal knowledge base. There is a lot of overlap between them, though knowledge bases sometimes use a more controlled publishing model.
Internal wiki vs knowledge base
Internal wikis and internal knowledge bases overlap, so many teams use the terms interchangeably.
A wiki usually puts more weight on collaborative editing and connected pages. Employees across the company contribute knowledge as they work, and the structure grows with the content.
A knowledge base often has a more controlled publishing model. A smaller group may own the content, with formal review or approval before information is published.
In reality, a company can have both models in the same workspace. An engineering section may be open for collaborative editing, and HR policies can have tighter permissions and ownership.
Internal wiki examples
An internal wiki can cover the whole company or focus on one area such as onboarding, processes, projects, or technical documentation. These are some of the most common examples.
Common internal wiki examples
- Employee handbook: Company policies, benefits, time-off rules, communication guidelines, team structures, and other HR information.
- Process and SOP library: Step-by-step instructions for recurring tasks, approval flows, checklists, software guides, and quality-control procedures.
- Project documentation hub: Project briefs, goals, responsibilities, decisions, meeting notes, research, timelines, and retrospectives.
- Training and onboarding wiki: First-week checklists, setup instructions, role-specific training, tool guides, team norms, and other material new employees need.
- Engineering and IT wiki: Architecture notes, development setup, runbooks, deployment instructions, incident procedures, infrastructure documentation, and system diagrams.
- Product wiki: User research, product principles, specifications, feature decisions, release processes, and recurring product questions.
- Sales and support wiki: Positioning, qualification criteria, objection handling, handoff processes, troubleshooting instructions, escalation procedures, and common customer questions.
Real-world internal wiki examples
A few companies publish parts of their internal documentation publicly, making it possible to see how a working company wiki is organized.
GitLab Handbook
The GitLab Handbook is the central repository for how GitLab runs the company. It contains more than 2,000 pages covering areas such as company policies, hiring, product, engineering, security, sales, finance, and operations.
GitLab follows a handbook-first approach, so changes to company processes are documented in the handbook and employees are expected to keep it current. Information that cannot be public is kept in a separate internal handbook. This is a useful example of a large wiki organized around functions and company processes.
37signals Employee Handbook
The 37signals Employee Handbook focuses more narrowly on employee information. Its sections cover getting started, benefits, how the company works, career development, internal systems, policies, and its code of conduct.
PostHog Handbook
PostHog also publishes its company handbook, covering how the company works, its teams, hiring, product development, communication, and other internal practices.
Why use an internal wiki?
An internal wiki is useful when important information is scattered across chat, shared drives, old documents, and individual employees.
Faster access to company knowledge
Employees have one place to search for processes, policies, technical documentation, decisions, and other frequently needed information. In Microsoft's 2023 Work Trend Index, 62% of survey respondents said too much of their workday was spent searching for information.
Easier onboarding
New employees can work through onboarding guides, team documentation, policies, and role-specific material at their own pace. Managers and coworkers spend less time answering the same setup questions for every new hire.
Less knowledge loss
Processes and decisions stay available when the person who originally knew them changes roles or leaves the company. A 2023 systematic review of 91 empirical studies examined how employee turnover leads to organizational knowledge loss.
Better asynchronous work
A well-maintained wiki gives employees access to the same information across offices and time zones. Decisions and processes do not depend on the right person being online when a question comes up.
Best internal wiki software
The best internal wiki software depends on how your company creates knowledge, how much control it needs, and where employees already look for information. It might be tempting to use familiar tools like Google Docs for your internal wiki, but dedicated software is usually a better choice.
For this comparison, we looked at how each tool handles the core requirements of an internal wiki: editing, navigation and search, content maintenance, permissions, version history, integrations, and ongoing administration.

Best open-source internal wiki software
Open-source internal wiki software gives your company more control over hosting, data, and customization. The software itself can be free, but your team is responsible for deployment, updates, backups, security, and ongoing maintenance.
| Tool | Best for | Hosting | Price | Main limitation |
|---|---|---|---|---|
| DokuWiki | Lightweight traditional company wikis | Self-hosted | Free | Older interface and more technical setup |
| Wiki.js | Modern self-hosted company wikis | Self-hosted | Free | Hosting, updates, backups, and security are your responsibility |
| BookStack | Simple documentation with a fixed hierarchy | Self-hosted | Free | The books, chapters, and pages structure is less flexible |
DokuWiki
DokuWiki is a lightweight open-source wiki that stores content in plain files and does not require a database. It includes search, page history, access controls, external authentication, and a large plugin ecosystem. It suits technical teams that want a traditional internal wiki they can host and maintain themselves.
Wiki.js
Wiki.js is a modern open-source wiki for companies that want to host their knowledge base on their own infrastructure. It supports visual editing and Markdown, along with integrations for authentication, search, storage, and Git. Your team is responsible for operating and securing the service.
BookStack
BookStack is a self-hosted wiki with a fixed structure of shelves, books, chapters, and pages. It includes search, page revisions, internal links, and role-based permissions. It works well for handbooks, SOPs, and technical documentation that fits naturally into a clear hierarchy.
How to choose internal wiki software
When comparing internal wiki tools, test them with realistic content and the people who will actually use them.
- Test the editing experience. Ask a few employees to create and update a page. See how quickly they can format content, add links, upload files, and make small corrections without training.
- Build a realistic structure. Create several sections and enough pages to resemble a real company wiki. Check how easy it is to reorganize content and connect related pages.
- Test search with real questions. Search using words that do not exactly match page titles. If the tool includes AI search, check whether answers cite their sources and respect permissions.
- Check how stale content is handled. Look for page ownership, review dates, verification, version history, analytics, and other ways to identify outdated information.
- Review permissions and administration. Check the controls available on the plan you would actually use, including groups, guest access, SSO, SCIM, audit logs, and granular permissions where relevant.
- Check the integrations you use. Test connections to tools such as Slack, Microsoft Teams, Jira, GitHub, Google Drive, or SharePoint.
- Consider hosting and maintenance. If you are considering self-hosted software, factor in updates, backups, security, and uptime.
- Compare the real cost. Price the plan you would need at your expected number of users, including features such as AI, SSO, longer version history, advanced permissions, and additional storage.
AI and internal wikis
AI can make an internal wiki easier to search by letting employees ask questions in natural language and get answers based on company documentation.
Useful AI wiki features include:
- Source citations: Links back to the pages used to generate an answer.
- Permission-aware answers: Employees only see information they already have access to.
- Connected search: Some tools can also search sources such as Slack, Google Drive, Jira, or SharePoint.
For example, Nuclino comes with an AI-powered assistant Sidekick that can instantly answer any question based on your team's collective knowledge documented in the wiki.
AI still depends on the quality of the underlying documentation. Outdated pages can lead to outdated answers.
How to create an internal wiki
You do not need to document the entire company before launching an internal wiki. Start with the information people already need, then expand it as the wiki gets used.
1. Choose the software
Pick a tool that employees can easily contribute to and that gives you the search, permissions, integrations, and administration your company needs.
The wiki software comparison above covers several hosted and open-source options. If you are using Nuclino, you can also follow its guide to setting up your first workspace.
2. Create a simple structure
Start with a small number of areas that employees will immediately recognize, for example:
- Company and HR
- Product
- Engineering
- Sales and support
- Processes and operations
You can add more structure later as the wiki grows. In Nuclino, workspaces can separate major topics or access levels, while collections group related pages within a workspace.
3. Add the content people need most
You do not need hundreds of pages at launch. Start with material employees already search for or ask about regularly:
- Onboarding guides and company policies
- Recurring processes and SOPs
- Product and project documentation
- Engineering and IT documentation
- Answers to common internal questions
For recurring page types, templates can save time and keep information consistent. Nuclino, for example, lets you turn existing pages into reusable item templates.
4. Invite the team and improve the wiki over time
Set appropriate access for the information you have added, then invite employees to use and contribute to the wiki. Important pages may need clear owners, while most day-to-day documentation can stay collaborative.
After launch, pay attention to what people search for, which questions still get asked, and where duplicate or outdated information starts to appear. Use those signals to decide what to add or improve next.
Common internal wiki problems
Even a well-designed wiki can become less useful over time. Common problems include:
- Outdated information: Old policies, processes, and instructions can quickly make employees lose trust in the wiki.
- Poor structure and search: If pages are hard to browse or find, people go back to asking coworkers or searching through chat.
- Duplicate pages: Multiple versions of the same information make it unclear which one is current.
- Low contribution: If updating the wiki feels like extra work, useful knowledge stays in personal notes, documents, or conversations.
What makes a good internal wiki?
Most of these problems can be prevented by making the wiki easy to maintain, search, and contribute to. A good internal wiki stays useful as the company grows and the information inside it changes.
Information stays current
Important pages should have clear owners, and teams should update them when the underlying process changes. Review dates or verification can help with information that needs to stay especially reliable.
People can find answers quickly
Employees should be able to find information without knowing exactly where it lives or what a page is called. Clear navigation, useful internal links, and reliable search all become more important as the wiki grows.
Each topic has a clear home
A simple structure makes it easier to know where new information belongs and reduces duplicate pages. Related content can still be connected with internal links without creating several versions of the same information.
Contributing is easy
Employees are more likely to document what they know when creating and updating a page is quick. Adding a missing step, correcting an old instruction, or linking related information should fit naturally into everyday work.
Access matches the information
Most company knowledge can be widely accessible, but HR, legal, security, compensation, and confidential project information may need tighter permissions.
Documentation becomes part of the work
Teams should update documentation as processes, products, and decisions change. If updating the wiki is treated as a separate cleanup task, it is much more likely to fall behind.
FAQ
