Swimm takes a unique approach to developer documentation by coupling docs directly with the code they describe. When you reference a code snippet in a Swimm document, it tracks that code and alerts you when it changes — or auto-updates the documentation to match. This solves the perennial problem of stale docs. The platform includes an AI assistant that can generate initial documentation from your code, suggest improvements, and answer questions about your codebase. Swimm documents live alongside your code in the repository and render beautifully in the IDE, GitHub, and Swimm's web app. The free tier supports small teams with enterprise features on paid plans.
