6. Notion: best for internal wikis
Why it wins
Notion makes it easy to write and organize internal documentation, processes and onboarding guides, and pages can be published to the web for simple public docs.

Common mistakes
- Choosing a standalone tool that doesn't connect to your inbox.
- Writing articles nobody searches for.
- Never updating articles after product changes.
- Hiding the help center so customers can't find it.
Measuring a knowledge base
Track views per article, searches with no results, article ratings and the number of tickets on topics that have articles. When an article gets many views but tickets on the topic stay high, rewrite it. When searches return nothing, write the missing article.
Writing tips that make tools work better
Short titles that match how customers phrase questions, one task per article, numbered steps, screenshots for interface steps and links to related articles. A tool can only surface what you write clearly.
Public help center or internal wiki?
A public help center answers customer questions and can bring search traffic, so it needs polished articles, clear navigation and a custom domain. An internal wiki holds processes, policies and onboarding notes for your team, so it needs good permissions, fast editing and links to the work itself. Many businesses use both: a help desk's knowledge base for customers and Notion or ClickUp for internal knowledge. Choosing one tool for both often means compromises on one side. Start with the side that costs you the most time today, which for most small support teams is customer questions.
Our verdict
Help Scout is the best knowledge base software for most small teams because the help center and shared inbox work together and the free plan covers 5 users. Zendesk and Freshdesk suit growing teams that need full ticketing; Intercom suits software companies; Notion is the simplest choice for internal wikis.
