10 Free Knowledge Base Software: Choosing a Digital Library in 2024

As the old proverb goes: “There is no such thing as a free lunch“. That’s fair. However, not always the case. In the business ecosystem, freebies of all kinds are beneficial.

The progress is non-stop, so more and more businesses are finding the best way to empower customers and streamline internal operations. One powerful tool that’s stealing the spotlight is free knowledge base software. 

In this post, we are diving headfirst into the world of wikis, help centers, and 10 other helpful resources your team would find top-notch. They redefine how companies organize, share, and access information. Let’s get the ball rolling! 🤝

What is knowledge management software?

Knowledge management software refers to a specialized tool that helps you keep, collect, organize, and share information. In fact, it can be used to manage miscellaneous types of data, such as:

  • Documents (presentations, reports, articles, etc.);
  • Media (images, videos, graphics, GIFs, etc.);
  • Expertise (skills of employees, customer feedback, community databases).

Generally, such software may take many forms, from small team-wide wikis to giant text corpora. Today, I would like to focus your attention on the knowledge base software that you can enjoy for free! But first, let’s look at the reasons why you should actually grab one.

Why does your business need free knowledge base software?

Before we proceed, it’s key to highlight an important caveat: so that your company provides professional, evergreen, and substantial knowledge, it should first realize its ultimate purpose:

Which type do you want your help hub to be: external – for customers or internal – for employees? Do you need a multilingual feature to communicate with international audiences?  

With that in mind, let’s comb through four clear-cut reasons why your team needs a steady knowledge base solution:

  1. Cost-efficiency: let’s face it – a startup or a small-sized business will rejoice at such a thing as a free piece of software. For much more giant corporations, this might be an excellent addition and a powerful backup to its main toolset. 
  1. Customer empowerment: as clients are now tech-savvier than ever, the ability to dig for information on their own only adds to their overall satisfaction. They can find the answers independently, without waiting for an answer, which reduces the workload on your team.
  1. Streamlining support operations: as soon as the thought of creating a knowledge base flounders in your mind, organizing and centralizing data in the company will be inevitable. These actions lead to faster troubleshooting and problem resolution, minimizing ticket volume significantly.
  1. Continuous improvement: free knowledge base software often comes with analytics that help you track user interactions and behavior. The insights you gain after a customer leaves feedback about an article or shares their thoughts in the chat open numerous areas for improvement and mark the gaps in your content.  

Must-have features of free knowledge base software 

The universal truth is that a knowledge base should be scalable and have an easily digestible structure. But then again, will it be enough for a fancy, big-sized business? Or for a small company just starting its journey but wanting to be up in arms? 

For that, one should get a birds-eye view of the functionalities a piece of software presents. I mean, this is directly linked to the way you lead the documentation! Thus, let’s elaborate on the must-have features such software should obtain:

  • Search functionality – when a user can’t find what they are looking for, the chances are they bid farewell and switch to another solution. To minimize that, make sure your help center has advanced search features to quickly discover the answers. Use keywords, phrases, and other mark words so that customers won’t stumble.
  • Information hierarchy – who likes a mishmash when it comes to a knowledge base? A strict and branch-like structure makes it easier to navigate the content and locate answers on specific topics. 
  • Integration options – multiply your efforts with integrations. For instance, you can enhance your resource center with a live chat or a chatbot for better self-service, streamlined support processes, and overall customer satisfaction. Speaking of, I know THE solution for that, stay tuned 😏
  • Multimedia support – walls of text have never been entertaining. To attract users and explain the ropes of your product or service to the fullest, add some images, GIFs, or pics. In other words, do everything to boost comprehensibility and engagement levels.
  • Analytics & insights – if you have built-in analytics, count your blessings! Today’s market is brimming with solutions that provide such a feature. Thanks to it, you have valuable data on user behavior, search patterns, and article performance. 
  • Export & import opportunities – suppose you are switching from one platform to another. So as not to fool away all your customers’ data, important articles, and stuff, make sure free knowledge base software is able to migrate and backup the content hands down.

A fully customizable live chat, a no-code chatbot, a shared inbox, and a popup builder for targeting the audience better yet. Even though these specs are worth your utmost attention, I’d like to plunge into the current agenda – the HelpCrunch multilingual knowledge base

You guessed it right, a user-intuitive editor that makes it possible to build a definitive structure. Thus, among the strong points of this tool, there are:

  • The WYSIWYG editor allows you to compose, manage, and assemble your knowledge base articles into one system with categories, subcategories, and sections. Plus, you have the freedom to embellish your resource center with images, videos, and GIFs, to name a few.
  • SEO compatibility that paves the way for your Google appearance. You can add meta titles, descriptions, and tags to every article and section.

  • Smart search that helps users strike the right info in a matter of seconds. Only personalized, relevant, and real-time suggestions.

Pricing. Documize prices start from $9/per user/year. To go for more, you need to splurge at least $900/year/up to 100 users.

  1. Guru

Over the past few years, Guru has upped its game significantly. The software allows you to set up articles directly in the program or sync them from internal wiki tools, employee intranet, and other third-party integrations. 

Looking for a way to combine your external knowledge base with an internal one? Guru lets you do just that. Thanks to its modern technical ground, you can keep all your data and content under one umbrella without losing critical nuggets of information.

  • Embeddable widgets – guides created with Stonly can be embedded directly into your website or application, providing users with instant access to information without leaving the page.
  • Analytics – even if the software is free, it doesn’t have to be operated on a roll of the dice. You can check the audience range, omit bounce rate, and see the exact moment when users seem to leave. 

Pricing. With a free 14-day trial, Stonly also offers rather straightforward pricing models. There are Small Business, starting from $249/month, and Enterprise with custom pricing.

Final words

Choosing the right free knowledge base software shouldn’t be a fine point. I have no doubt that after you have read this article and ended up here, your mind has a definitive solution. Always remember, though, that the go-to software should, at the very least, allow for clear structure and SEO functions.


Is the knowledge base free?

Yes, it can be free, and there is lots of such knowledge base software on the market. While a solution that doesn’t cost a dime isn’t a rare case, it still may be limited in functionalities. 

For instance, if you have a multinational company, you probably serve diverse audiences. They need their demands catered to. If you provide them with only one language in the knowledge base, the chances are they will be confused and feel underrated. 

To solve this problem, you should have a multilingual knowledge base (preferably integrated into the chat widget) which sometimes comes in Pro/Enterprise/Premium packages.

How to know which free knowledge base tool or free trial is right for you?

There is no better way to know which free knowledge base tool or free trial is right for you than just signing up for it and giving it a proper go. 

Sure thing, you can just surf the Internet and compare the options. And it’s almost definitive that you will stumble onto companies promising you pie in the sky. Surprisingly so, the majority might not be the case for your business for several reasons: 1) they lack proper features, enough to meet every need, and 2) they aren’t keeping up with the times and lagging in development. 

After you’re all set, and your free trial is coming to an end, make sure the team behind the preferred solution is transparent about their upgrade options. There should be no hidden fees, no pitfalls, and some new, negative surprises as soon as you pay your first penny.

Does a free knowledge base deliver an omnichannel experience?

A free knowledge base itself doesn’t inherently deliver an omnichannel experience, but it can be a component of an omnichannel strategy. So there are several ways for that:

  • Consistency – By maintaining consistent and accurate information across all channels, including the knowledge base, you ensure that customers receive the same answers regardless of where they seek help.
  • Self-Service – A knowledge base allows customers to find answers on their own, reducing the need to contact customer support through various channels. This can be especially useful for straightforward queries.
  • Availability – A knowledge base is accessible 24/7, providing customers with immediate help outside of regular business hours.
  • Channel Integration – Some knowledge base platforms offer integrations with other customer support tools, like live chat, ticketing systems, and email. This enables customers to seamlessly transition from self-service to a live agent when needed.

What is the knowledge base used in AI?

As the AI era sets in, knowledge bases stand a good chance of becoming more powerful, feature-packed, and sophisticated. They can take various forms, ranging from structured databases to unstructured text corpora. Currently, businesses all across the globe already use them to enhance their understanding, reasoning, and decision-making capabilities.
