Top 14 knowledge base software for 2024

You’ve likely heard the phrase “knowledge is power,” and the adage rings just as true regarding customer service. Empowered customers armed with information are more likely to resolve issues independently, leading to better user experiences. But building and maintaining all that knowledge can feel like wrangling cats—unless you use knowledge base software.

A knowledge base is a digital library of self-service support resources that empowers customers (and employees) to find answers on their own terms. The right software makes it easier for businesses to create and maintain one. Here, we'll delve into the knowledge base software market, explore what it offers, and unveil the top contenders in the software arena so you can choose the perfect solution for your service needs.

Knowledge base software helps businesses create, manage, and share internal and external content in an organized and searchable format. There are two main types:

• External knowledge bases: a centralized content directory focused on your products or services—and how to use them—for your customers to reference
• Internal knowledge bases: a tool for distributing information about systems, processes, and policies to your employees

Knowledge base systems vs. help desks

Knowledge base systems and help desks can sometimes be confused because they are both support tools, but they serve distinct purposes. Knowledge base systems are essentially self-service libraries, empowering users to find answers to frequently asked questions, troubleshooting guides, and how-to articles.

Help desks, on the other hand, encompass multiple support tools, often including knowledge base software. They facilitate self-service and streamline support interactions between users and agents. They also feature ticketing systems, allowing customers (and employees) to submit requests and track their progress while agents manage and resolve issues. To promote knowledge sharing and self-service, you must ensure your help desk includes knowledge base software.

For small businesses just starting out, a knowledge base might simply be a shared Google Drive with PDFs of product specs, customer FAQs, and employee onboarding manuals. But as the business grows, this can create issues with security, searchability, and accessibility. Here are the common types of knowledge base tools for businesses of any size.

• FAQ pages provide answers to the most common customer questions.
• Chatbots are AI-powered tools that proactively direct customers or employees to knowledge base content and suggest relevant articles when users ask questions.
• Generative AI is a type of AI technology that can help teams write knowledge base content, change the tone of articles, and flag outdated information.
• Community forums are online portals where users engage in discussions, share information, ask questions, and collaborate.
• Self-service portals are online platforms where users independently access information, find solutions to issues, and perform tasks without direct assistance.
• Help centers are centralized online repositories that host a knowledge base, community forum, and self-service portal from one centralized location.

When you consolidate your institutional knowledge into a single database accessible from anywhere on the internet, you encourage customers and employees to self-serve, which benefits efficiency. Here are five other reasons why knowledge base systems are important.

Boosts customer satisfaction

An external knowledge base never sleeps, so you can give your customers the information they want—whenever and wherever they want it. This enables your users to get 24/7 support from your company, even during holidays and off-hours. The customer doesn’t need to wait for an agent to help them fix an issue they can easily resolve on their own, creating a convenient experience that boosts customer satisfaction.

Saves agents time and reduces costs

Self-service resources can help customers and employees resolve basic issues without agent intervention, deflect tickets, and keep the queue manageable. As a result, support agents can focus on solving more complex problems and handle growing ticket volumes with fewer resources.

When integrated with chatbot software, knowledge bases can also automate support, so your business can tackle higher ticket volumes without adding headcount. For example, Zendesk AI enables you to use the knowledge from your help center to craft accurate, conversational bot responses.

Enhances customer onboarding and increases product adoption

Use your external knowledge base to create a seamless customer onboarding experience. When a new customer signs up, you can automate a welcome email that contains helpful resources from your knowledge base, such as:

• Product tours and overviews
• How-to videos and tutorials
• Help center articles
• Frequently asked questions

These onboarding materials deliver immediate value and encourage new customers to adopt your product faster.

Breaks down internal silos

Internal knowledge base tools can remove internal data silos by providing a centralized location for teams to access important information. When data lives across systems and departments, it’s difficult for employees to find what they need, negatively impacting efficiency. Knowledge base software provides easy access to valuable and relevant information, such as employee perks and employee leave policies.

Improves agent training and accuracy

With information a single click away in your internal knowledge base, agents can efficiently and accurately help customers without needing to memorize every detail. A knowledge base acts as a hard drive for your agents, allowing instant access to internal processes, FAQs, and articles for quick answers on demand. This also accelerates agent onboarding and gives new hires access to training materials.

A basic function of knowledge base software is to make it easy for customer, IT, and HR support teams to create, manage, and share content with their customers or employees. Here are a few essential features that knowledge base software should include.

AI knowledge base features

AI can play an important role in helping you create and manage your knowledge base. AI-powered help center tools can encompass:

• Semantic search and natural language processing (NLP): AI can go beyond simple keyword matching in searches. NLP allows users to ask questions in natural language, understand the intent behind the query, and provide more relevant and accurate results.
• Topic identification: AI-powered support topic identification automatically reviews incoming support tickets and identifies common questions and keywords. This enables you to identify topic gaps and address them with new help center content.
• Content creation: AI can help you write knowledge base articles by automatically turning a few bullet points into a complete article. It can also shift the tone to be more friendly or formal.
• Content maintenance: AI analyzes existing content to identify underperforming help center articles so you can either improve or archive content that is no longer relevant.
• AI-powered chatbots and AI agents: Integrating AI-powered chatbots or AI agents within the knowledge base allows users to interact conversationally and receive immediate answers to simple questions, further enhancing self-service capabilities. You can also leverage your knowledge base content to build bot conversation flows.

Front-end knowledge base features

In the context of a knowledge base, the "front end" refers to the user interface the target audience interacts with. It includes key features like:

• Search functionality: A powerful search engine enables users to find the information they need. Features like faceted search, search suggestions, and natural language processing can enhance discoverability.
• Content hierarchy and organization: Well-organized content with clear categories, subcategories, and tags makes it easier for users to navigate the knowledge base and find the specific information they want.
• Responsive design: A knowledge base needs to adapt to different screen sizes (desktop, tablet, mobile) to create a great user experience.
• Self-service options: Features like FAQs, step-by-step guides, and troubleshooting articles empower customers to solve problems independently, reducing support ticket volume for agents.
• Multilingual support: For businesses with a global audience, offering knowledge base content in multiple languages is essential to ensure accessibility and improve customer satisfaction.

Back-end knowledge management features

The "back end" refers to the internal functionalities and systems administrators and editors use to manage and maintain the knowledge base. This includes knowledge management tools like:

• User management and permissions: The ability to assign different access levels and permissions to users ensures content security and allows for controlled contribution and editing within the knowledge base.
• Content workflows and collaboration: Features like content approval workflows, version control, and co-authoring tools streamline the content creation and editing process, promoting collaboration and maintaining consistency.
• Single sign-on (SSO): Integration with existing SSO systems allows users to access the knowledge base with their existing credentials, improving user experience and security.
• Bulk import and export: The ability to import existing content from other sources (e.g., documents, PDFs) and export content in various formats (e.g., CSV) saves time and simplifies knowledge base setup and maintenance.
• Analytics and reporting: Detailed analytics provide comprehensive insights into user behavior within the knowledge base. This allows for data-driven decisions regarding content optimization, identifying popular topics, and understanding user search patterns.
• Branding and customization: The ability to customize the look and feel of your knowledge base to match your branding ensures a consistent user experience across all touchpoints.

Here are a few considerations when picking the best knowledge base software and system for your business.

Make sure it’s secure

The best knowledge base software has safeguards in place to protect sensitive data. With up-to-date software compliance certifications, businesses demonstrate that they abide by industry restrictions and regulations to keep data secure. Zendesk gives businesses user authentication options, data encryption, device management, and more.

Vet how easy it is to set up and maintain

Pick software that deploys quickly and offers the tools you need for easy maintenance. It’s also wise to choose a tool that requires minimal onboarding and training so you can get up and running swiftly. A fast time to value means you start seeing the benefits of the software sooner rather than later.

Consider the total cost of ownership

With any software, you want a quick return on investment (ROI), but those gains can be delayed by unforeseen costs and endless add-ons that inflate your budget. Ideally, your chosen solution won’t require a large technical team or development resources to maintain it. Look for software that prioritizes automation and built-in efficiency, allowing your team to focus on creating valuable content and not getting bogged down by technical complexities.

Prioritize scalability

Choosing scalable knowledge base software is paramount for businesses seeking a long-term solution. As your company grows and your information needs evolve, a scalable platform will seamlessly adapt to advancing needs. This ensures your knowledge base can accommodate an expanding content library and integrate with future systems without requiring a costly and disruptive software overhaul down the line.

Free knowledge base software provides an affordable entry point to managing content, but you may quickly outgrow its basic features. When that happens, you might find the cost to upgrade and manage the system exceeds that of other paid services.
