AI extensions

AI extensions let you add custom interactivity to your Felt maps, transforming your map into a purpose-built interactive experience, without writing any code. Felt AI leverages the JS SDK to generate the tools, panels, and workflows you describe in natural language. Everything happens right in Felt: you can preview, adjust, and save your extension with no extra setup or deployment. When you share your map, your application is live and ready for viewers to use.
