How is Featurebase different from Outline?

Featurebase is a lot more than just a knowledge base tool. We offer a suite of tools that help support, product, and GTM teams build products users love. That includes an AI-powered support inbox, live chat, feedback collection & management, in-app surveys, changelogs, and loads of integrations with other tools.

Can I show help articles inside my product?

Absolutely. You can effortlessly embed Featurebase’s in-app widget into your product or website, to enable users to search for help articles or even chat with our team and AI agents.

Can I control who can access my help articles?

Yes. You can keep your help articles public, share them privately with your team or specific customer segments, and restrict access to signed-in users only. Featurebase’s Help Center is perfect for both internal knowledge management and support.

Can I have my help center in multiple languages?

Absolutely! You can set up your help center to support over 70 languages. The help center will automatically display in your users’ language based on their browser settings. Translate with AI and keep your product names as protected terms, or write a translation by hand.

Does Fibi use the Help Center?

Yes. Fibi, our AI agent, answers from your articles and the other sources you connect. When it cannot answer, it hands the conversation to your team.

Can AI tools read my docs?

Yes. Every article has a Markdown version, and your help center has an llms.txt file. On public pages, readers can open the article in ChatGPT or Claude from the page menu.
