If you feel like your team could fill a library with everything they know about your company and its products, that’s probably because they can.
And the sooner you get that knowledge out of people’s heads and onto a page, the better off your company will be. Documenting your team’s hard-won knowledge makes it easier to onboard new employees, share information across departments, and teach customers about new product features.
But an actual library probably isn’t the answer. Instead, you need a digital knowledge base (or wiki) that your team or customers can access from anywhere. GitBook is one of the most popular knowledge-base software programs, but if your team isn’t in SaaS product development or you can’t afford GitBook’s prices, it may not be right for you.
Discover the 10 best GitBook alternatives for teams of all types, and start building your own company wiki.
GitBook is a knowledge base tool to help technical teams create documentation. Its features were made with developers and SaaS product designers in mind, but you can use it for other types of online documentation as well.
You can use GitBook to create internal and external documentation—whether you’re publishing product documentation to your customers or outlining a knowledge base for company terms and processes.
GitBook is flexible enough to let developers code their way through documentation—with options for Markdown or WYSIWYG editing. But it also offers templates and a drag-and-drop block editor for the non-coders on your team. You can tag your colleagues for better collaboration, and you can nest pages for better organization.
The best GitBook alternative for your team will depend on your company’s needs and budget. Here are some things to consider as you weigh your options:
