What is Ask Fern?
Ask Fern is Fern’s AI Search feature that indexes your documentation and provides an interface for your end users to ask questions and get answers. It appears as a side panel on your documentation site so users can ask questions without leaving the page.
Ask Fern helps you:
- Reduce support burden – Enable your users to quickly find answers in your documentation without contacting your support team.
- Accelerate user onboarding – Help users integrate your product faster by surfacing relevant code samples and guides.
- Identify documentation gaps – Understand where your docs need improvement through user search patterns and feedback.
