DocSearch

DocSearch is a search service from Algolia for documentation sites and blogs. It crawls your pages and gives visitors fast search, with an AI answer option for common questions.

DocSearch indexes your docs on a schedule, so you do not need to reindex by hand, and readers search them from a command palette or a sidepanel. Adapters exist for Docusaurus and VitePress, and a vanilla JavaScript build covers other sites. A visual config editor lets you choose what gets indexed. The Ask AI feature gives answers with links to the real sources in your docs.

Eligibility for the free tier depends on the type of project, so check the sign up page before you apply.
