If you want to use OpenAI API to generate technical specs for development projects, Story Spec is a great choice. The tool turns user stories into detailed technical specs, including descriptions, acceptance criteria, risks and edge cases. It uses OpenAI through a user-supplied API key, which is stored securely in the browser, so it's a good option for a lot of different members of your development team.
Another good option is Pipedream, which lets developers build complex apps that span their stack of services. Pipedream has access to more than 2,100 APIs, including OpenAI, and lets developers control low-level code when needed and use no-code interfaces when not. Its instant deployment and access to npm and PyPI packages make it a good option for building AI into your development projects.
