Nut.new is an innovative tool designed to help users build complete applications without coding by leveraging AI to fix bugs more effectively than existing solutions like Bolt and Lovable. It utilizes the Nut API to record an app's behavior, analyze issues, and provide explanations to create reliable fixes. Users can chat with the AI to develop the initial app, import existing projects, and enhance them continuously. When encountering bugs, users describe the issue and use the "Fix Bug" button to generate a detailed analysis, allowing the AI to determine the problem's root cause through a combination of basic and advanced techniques. Nut.new, which is open-source and free, encourages user feedback to improve its functionality and offers unlimited access to early adopters who contribute feedback. It is based on Bolt.diy and allows users to integrate their Anthropic API key for extensive use.
