ChatGPT Apps allow developers to integrate their products directly into ChatGPT conversations, creating a more interactive experience. Developers often make the mistake of trying to replicate their entire product within ChatGPT, but that approach doesn’t work well. Instead, they should focus on specific capabilities that the model can utilize in various conversations. A ChatGPT app is not a standalone product; rather, it’s a toolkit with defined functions that can assist users at key moments in the conversation. The goal is to create a clear and compact API, allowing easy access to essential operations without overwhelming users with unnecessary features. To determine if an app adds value, developers should focus on three areas: knowledge, actions, and presentation. An app should provide new information that users can’t access in ChatGPT on their own, perform actions on users’ behalf, or present data in a clearer format than plain text. For instance, an app like Zillow enhances the property-search experience by allowing users to look up live listings within the conversation itself. This integration keeps users engaged without forcing them to switch contexts or navigate away from their chat. When developing a ChatGPT app, it’s important to concentrate on the core jobs that users want to accomplish instead of listing all features. By identifying specific outcomes—like helping someone find a home or creating polished presentations—developers can ensure their app meets real user needs. This focus on user outcomes, rather than a feature checklist, simplifies design decisions and enhances the app's effectiveness in conversations.
