Want to jump straight to the answer? The best knowledge base software for most people is Heroic KB or Helpjuice.

We live in a world that revolves around customer service. Whether it’s customer service about how to use a product or a service, that service is key to the customer’s happiness, and thus the company. 

Enter knowledge base software. This fairly new concept has eliminated the need for the archaic practice of printing and shipping physical copies of instruction manuals for products and services. 

Instead, knowledge base software is a digital resource that customers and employees alike can use to find solutions without having to call or chat with a customer service representative. That’s thanks to the software’s self-help articles that are available 24 hours a day, 7 days a week, 365 days a year. 

Knowledge base software has revolutionized the idea of support for products and services by making the information much more accessible, which drastically reduces wait times for customers while simultaneously lowering the number of support ticket requests. This software helps people find answers quicker, which is what we all want.

How to Find the Best Knowledge Base Software For You

Are you wondering how we narrowed our list down to these top eight knowledge base software programs? Below, we’ll share the methodology we used when researching and analyzing each program. You can use the same methodology as you’re comparing different knowledge base solutions for your business.

It’s important to keep in mind that generally speaking, there’s no “best for all” knowledge base software. It depends on what you need. These considerations can help you understand your needs and pick the best knowledge base software accordingly.

Type of Knowledge Base Software

Knowledge base software comes in all different shapes and sizes. In addition to standalone tools dedicated to knowledge base software, you can find knowledge base software modules built into other solutions, such as all-in-one help desk and customer support software. There are even knowledge base WordPress themes and knowledge base solutions built for ITSM.

If you want to take your customer service to the next level, consider an all-in-one support suite. Otherwise, a standalone knowledge base software will be just fine.

Public vs. Internal Uses

Most people associate knowledge base software with customer service. But these tools are also extremely useful for internal support.

Employees can reference an internal knowledge base for onboarding questions or self-help with specific procedures. This improves employee efficiency and helps keep managers from having to answer the same questions time and again.

Some knowledge base software allows admins to control whether an article is for public or internal use. But if you’re only going to use knowledge base software internally, certain platforms are built explicitly for internal knowledge bases.

Text Editing Capabilities

If it’s difficult to write and create an article, the quality of the content will suffer. The best knowledge base solutions have simple text editors. These editors let writers easily add images, videos, and highlights to emphasize important sections of an article.

User-friendly text editing is crucial for technical documentation, as the content in these articles can be challenging to follow. A simple text editor will make things easier for the person writing the articles, which ultimately improves the end user’s experience.

Analytics and Reports Included

Analytics help businesses identify top-performing help articles. They also help companies improve articles that aren’t answering questions sufficiently. Analytics and reports can also help you see what types of questions people want answers to. You can then create more content within those categories instead of wasting time improving articles with zero views.

If analytics and reports are important to you, explore the different analytics tools offered by each knowledge base software program.

The Top Knowledge Base Software in Summary

In today’s day and age, customers want answers immediately. Adding a knowledge base to your website is one of the best ways to deliver this experience.

Helpjuice is our top recommendation for businesses scaling their support teams. Document360 is the best choice for technical documentation. For an all-in-one customer support suite that goes beyond a knowledge base, try Zendesk.
