What makes a great ChatGPT app | OpenAI Developers

This post provides practical guidance for developers, PMs, and designers on building effective ChatGPT apps. It defines a ChatGPT app as a set of well-defined tools that can perform tasks, trigger interactions, or access data, emphasizing 'capabilities' over full product porting. It outlines three core value propositions: 'Know' (accessing new data), 'Do' (taking actions), and 'Show' (presenting information in a clearer UI). The post details how to select capabilities by focusing on core jobs-to-be-done and identifying gaps where the app uniquely helps, translating these into clearly named operations. It also provides strategies for designing for conversation and discovery, including handling vague and specific user intents, and using tool descriptions for model invocation.
