Build apps for Meta devices by describing your idea; Replit generates device-specific instructions and QR-code previews for on-device testing. Muse can now create Replit apps directly from conversation, turning ideas into working applications. Visualize data with inline charts in your Replit conversation powered by Atta, letting you explore findings without switching tools. Connect Agent to Airwallex via MCP to build and test payment integrations safely in the sandbox. Choose GPT-6 Sol, GPT-6 Luna Fast, or Claude Opus 5.5 when building with Agent, subject to your tier and workspace policies.
