Replit shouldn’t need any introduction. It is a wonderful tool for building sophisticated apps with AI. For simple apps, it is possible to just vibe code by writing a few sentences. If you are building a complex app, you need to plan. This helps you brainstorm and plan your project without touching the code. You will be able to get your thoughts and project organized before switching to the Build mode.

In this mode, you can brainstorm ideas, collaborate with AI on feature planning, and ask questions to get answers safely without changing your project’s code. In this mode, Agent is prohibited from making any code changes. Queuing is also disabled. In this mode, you will get a plan for new features.
