Knowledge base software

Knowledge base software, explained without the sales pitch

Knowledge base software is how you publish the articles that answer your customers' questions, so they find the answer instead of emailing you. This page covers what the category actually contains, then points you at the comparison that matches what you are trying to buy.

Four products wear the same name

Buying from the wrong category is the most common and most expensive mistake here, and it is usually only obvious a year later. Work out which of these you are shopping for before you compare anything.

Customers

A dedicated knowledge base

The public, branded help center is the whole product. Right when customers are the readers and deflection is the goal.

Tickets too

A help desk with docs attached

Ticketing first, knowledge base second. Right when you need a shared inbox in the same purchase, though the docs half is usually the weaker one.

Staff

An internal wiki

Built for your team to write for itself. Excellent at collaboration, and not built to publish something a search engine can find.

Engineers

Docs-as-code

Markdown in a Git repo, for engineers writing developer documentation. Powerful, and the wrong shape for a support team maintaining help articles.

FAQ

Knowledge base software questions

What is knowledge base software?
Knowledge base software is a tool for writing, organizing and publishing the articles that answer your customers' questions, so they can find the answer without contacting you. In practice it bundles three things: an editor your team will actually use, search that finds the right article, and hosting that puts it on your own domain looking like your product. Our roundup of the best knowledge base software compares twelve of them.
What is the difference between knowledge base software and a help desk?
A knowledge base is the documentation customers read to answer their own questions. A help desk is the ticketing system your team uses to answer whatever still comes in. Several products bundle both, which is convenient but usually means one half is stronger than the other. Knowledge base vs help desk covers where the line sits.
How much does knowledge base software cost?
Published entry prices range from free to around $250 a month, with most dedicated tools between $25 and $130. The pricing model matters more than the headline number, because per agent, per seat, per author, per resolution and flat all behave very differently as you grow. HelpDocs is flat and published from $129/mo with unlimited free public readers.
Do I need knowledge base software, or will a wiki do?
A wiki like Notion or Confluence is fine for internal notes and is often the right first step. It becomes the wrong tool when you need a public, branded, search-indexable help center, because you lose the things that make one work: strong search, failed-search reporting, article feedback and deflection analytics. Internal vs external knowledge base explains the split.
Can I move my existing articles into new knowledge base software?
Usually, but check for a real importer rather than assuming. HelpDocs has one-click migrations from Zendesk, Intercom, Help Scout, ReadMe, Helpjuice and ProProfs, documented in importing from another service. Where there is no first-party importer you are exporting and reimporting via CSV or an API, which is slower but workable. Map old URLs to new ones before switching domains, or you lose the search traffic those pages earned.
