What is an AI knowledge base?

An AI knowledge base is a centralized repository of information that uses artificial intelligence and natural language processing to help users find, retrieve, and interact with content more effectively. It typically stores FAQs, how-to guides, product documentation, internal company knowledge, and other structured or unstructured information.

AI development companies often build or customize these solutions so that organizations can get tailored, high-performing knowledge systems that fit their specific needs.

So, what makes a knowledge base AI? These are some of the most common features:

• Natural language search: Users can ask questions in plain language instead of using exact keywords, which shortens the time it takes to find a useful answer.
• Automated content suggestions: The system can recommend relevant articles based on user behavior or queries. So, if someone's been searching e.g., for "dashboard design", it can give tips on adding tooltips to dashboards.
• Chatbot integration: AI chatbots can use the knowledge base to answer customer or employee questions automatically. Instead of using search to go through knowledge base articles, you can ask questions in plain English and get responses.
• Content generation and summarization: Some AI knowledge bases help create or update content using generative AI tools. For example, you can feed it some body of content and it can create new knowledge base articles on its own. Popular AI tools for e-commerce can do this too.
• Learning and improvement: The system can improve over time based on how users interact with it, identifying knowledge gaps or popular topics. Based on user feedback, it can suggest what to add to improve your customer self service efforts.

The benefits of using an AI knowledge base over traditional knowledge bases

Perhaps you're still using your old knowledge management tool, and you think it provides accurate and relevant information and doesn't need changing. The reality is that an AI-powered knowledge base has a lot to offer, and if you're not using one already, you're behind the competition. 😬

Here is what you can gain by using an AI knowledge base:

• Faster, more accurate search functionality: users can ask full questions instead of guessing the right keywords. AI can also interpret context thanks to machine learning models, which means that users get what they really need every time.
• Personalized content delivery: an AI-powered knowledge base can suggest content to a user based on their previous activity.
• Automated support: your support team can have more time because the AI algorithm taps into the knowledge base software as a source for all of its answers. It digs deep into company data to provide the user with relevant information, helping (but not replacing) your support team.
• Smart content creation and maintenance: AI tools can help generate new articles, update existing ones based on user feedback, or summarize lengthy or complex information, and improve wording with a rewording tool.
• Continuous improvement and learning: unlike traditional knowledge bases, an AI-powered knowledge base learns from its interactions with users. It can analyze which knowledge base articles get a lot of views, which ones the users don't find detailed enough, and in general, what works and doesn't work well.
• Multilingual knowledge management: AI models can easily translate your AI-driven knowledge base into many languages, helping you become present globally. For example, our knowledge base platform supports over 40 different languages.
