Free knowledge base (KB) software is a tool that enables organizations to collect, organize, and share information from a centralized storage space. This free software makes information easily accessible to all users, improving customer self-service and employee self-service.

There are three types of knowledge base software designed to improve knowledge-centered service and allow users to seek out individual answers. Dive into each type of KB below.

Internal knowledge bases

An internal knowledge baseis an operational library filled with every database, document, procedure, file, and policy that dictates businessoperations.

Internal knowledge bases support:

• Standard operating procedures (SOPs): Detailed instructions that cover safe task completion

• Employee handbooks: Written documents outlining procedures, policies, and other information

• Process and project documentation: Materials capturing important project and process data, including timelines, goals, and risks

• Sales documentation: Written materials facilitating communication and action between buyers and sellers

These knowledge bases (KBs) are employee self-service portals, helping agents access information themselves rather than running to a colleague or superior.

External knowledge bases

An external knowledge base is a resource customers can use to find moreinformation on a company, product, or service. These KBs simplify customer relationship management (CRM) and provide access to:

• Software documentation: Detailed materials describing the goals and expectations of a software solution

• Product documentation: Written materials covering how a product works and its intended use

• FAQs: Consistent answers to common questions

• Guides and manuals: Documents offering step-by-step instructions on how to set up, use, or disable services and products

To enhance external KB capabilities, businesses may use additional solutions like FAQ software and customer self-service portals.

Open-source knowledge bases

Open-source knowledge bases use source code that is publicly available and customizable. These types of KBs provide:

• Centralized repositories for storing data
• Internal and external sharing options for customers and employees
• Personalization, including specifications for data storage and structure updates

Due to their code-heavy structure, these KBs can require additional technical know-how to customize and deploy.

Free knowledge base tools and client portal software help agents and customers solve their own problems on their own time. Dive into the additional benefits of free KB software options below.

Enhanced customer experiences and retention

By providing customers and agents with a verified source of truth where they can find answers to their problems, knowledge bases quickly answer FAQs, solve repetitive problems, and more. KBs with knowledge base chatbots also help teams free up human agents to handle complex problems, improving CX by reducing wait times. 

Plus, free KB software allows organizations of any size to adopt a general or AI knowledge base for streamlining processes and data organization. This makes it easier for agents and customers to find information, which increases loyalty and customer retention.

Increased team collaboration 

Every department plays its role in building and maintaining strong customer relationships. Ensuring that each department has access to the most accurate and up-to-date company information allows teams to prioritize internal collaboration and move joint projects forward with greater speed.

Improved productivity and training

Free internal knowledge base software provides a cost-effective way for new hires to seek out answers individually, regardless of their manager’s availability during employee onboarding. This results in faster-paced customer service training, where new hires are empowered to independently problem-solve. This skill can then be carried into an agent’s daily responsibilities, helping teams improve agent productivity and efficiency from the start.

Customized code modification

Free knowledge base software, sometimes referred to as an open-source knowledge base, should offer users the flexibility to build unique KBs based on organizational needs and preferences. Customizable hierarchies, drag-and-drop rearrangement capabilities, and the ability to create distinct sections or categories are essential. Plus, its adaptability to data categorization, tagging, and structure is an important metric when evaluating a service’s potential.

Whether your knowledge management tool is free or offers a free trial, these are the key features you should consider:

• User-friendly interface: Choose an adaptable but easy-to-navigate solution and consider a system with a conversational interface for intelligent KBs.

• Integrations: The Zendesk Marketplace offers more than 1,800 integration options, allowing businesses to connect free knowledge bases to existing tech stacks.

• Content and revision history: This feature allows users to access old versions of articles and reinstate the original content, ensuring transparency and accountability.

• Help center search engine: Typically the first point of contact, these search engines can decipher meaning despite spelling or incorrect language usage and help optimize KBs for SEO.

• Analytics and reporting: Reporting and analytics features help users gauge the effectiveness and relevance of their content. They use help desk metrics to provide insights into page views, most-read articles, and search terms used.

• Templates: Pre-built knowledge base article templates give users an easy, structured, and consistent starting point to create their content and get the knowledge base live more quickly.

These features help free knowledge base software provide an accessible point of entry for businesses to offer self-service options.

To build a KB from scratch, you need to choose the right AI-powered knowledge base with pre-designed, customizable templates that enhance content discovery and align with your brand. To start:

1. Determine the type of KB you need, as some free software providers only provide one type.
2. Identify your must-have features, as free KBs often have limitations, and there are no universal features across providers.
3. Set a budget and compare which plans best match your goals.
4. Integrate your chosen software with your current tech stack.
5. Create and upload content optimized for search engines.
6. Regularly update and maintain your knowledge base articles for accuracy and relevancy.

Additionally, consider these KB design best practices when creating your knowledge base:

• Aesthetics: Be intentional about using colors, fonts, spacing, shapes, and white space.

• Formatting: Prioritize the strategic application of call-outs, hyperlinks, warnings, headers, and tables.

• Navigation: Design a well-organized menu with hierarchical categories that support seamless browsing.

• Optimization: Leverage relevant keywords and smart tagging to enhance search functionality.

When investing in free software, ensure your selected solution has these capabilities, or consider upgrading to a free or extended trial of a paid KB.

Before deciding on the right free knowledge base software for your business, you need to understand your organization's needs and the role your KB will play. Here are a few useful criteria to help you decide:

• Search capabilities: Identify the search capabilities of your selected solution and verify its ability to search for keywords and industry- or company-specific terms.

• Use cases: Some free knowledge bases are only available as internal resources, or they only allow you to create one knowledge base, so consider whether you need multiple KBs or external support.

• Scalability: As your company grows, it is essential to have software with advanced features and capabilities that can grow and scale with your support operations.

• Security: Some free trials or knowledge base options may not have important security features that keep company information safe and prioritize customer data protection.

• Multilingual support: For businesses with a global reach (or those looking to expand), multilingual support is crucial and may not be supported by many free knowledge base software options.

While a free KB may be enough to support your business now, many high-quality features or AI-powered systems are only available for paid knowledge bases.
