Published by in Customer Service Software

As a business owner, you may be aware of the benefits of knowledge management software—you can create knowledge bases, manage employee access to information, facilitate employee training, and foster collaboration.

Though some businesses pay big bucks for a knowledge management tool, you don’t have to (at least till you’re convinced). There are several knowledge management software products that cost nothing to use.

Below, you’ll find the five best free knowledge management software tools and what each costs to upgrade. These tools (arranged alphabetically) have been picked from Capterra’s 2021 Shortlist for top knowledge management products where each product has a minimum user rating of 4 (out of 5) and at least 10 user reviews (see full selection methodology here).

How to choose the right free knowledge management software for your business

These considerations can make selecting a free knowledge management tool a little easier:

  • Check how much you need to spend on other aspects such as training and support. If it’s too much, then a free product won’t save you much money.
  • Look for a scalable solution. As your business grows, you’ll need to handle more data, more entities, and more complex operations.
  • Compare the free usage limits of the products (such as the number of users and available features) and shortlist tools according to your requirements.
  • Ask the vendor about integration options. Integration with existing solutions such as customer service, help desk, or ticketing software can help cut down a lot of effort and time in reconciling data between systems. Also, check if the vendor offers APIs so you can build your own integrations.

Common questions to ask while selecting a free knowledge management tool

It’s important to get answers from software providers or their sales representatives to clear any concerns before finalizing a decision. Here are a few key questions to consider asking:

  • Will I need additional training to use the tool? Check with the software provider how complex the tool is. Ask if you’ll need additional training to get familiar with its features and if this training will cost you extra.
  • Does the software upgrade cost include phone-based tech support? This will help you get clarity on the type of premium support you’ll receive when you start paying for the software.
  • Can I speak to a customer who has used your tool in the past six months? The answer to this will help you understand if the vendor puts in efforts to ensure customer satisfaction. If the vendor is reluctant to share the details, then it’s a sign that you may not get the customer service you expect.

Thanks for suggesting Bitrix24, looks very powerful for being free.

There’s also, which has a free tier. They’re new, but they’re good! You can keep the Knowledge Base internal to the company, or share certain articles on the public web. Plus, in addition to the Knowledge Base, you get a kick-ass form builder too!
