SPEC WRITER is a GPT designed to transform unstructured feature ideas into detailed software specifications. This tool allows users to efficiently craft software specs, meeting the need for a structured document that clearly outlines the functionality, purpose, interface, and other crucial details of a software project. SPEC WRITER takes in raw, undefined software feature concepts and adds structure and precision, thereby making it easier for development teams to understand and implement the requested features. Some of the envisioned usage scenarios include creating a chat app for different animal sizes, or even unique ideas like an application for songs created by rocks hitting treebark at different distances and angles. To start using SPEC WRITER, users will provide their feature ideas. Following this, the tool will guide the user and ask necessary questions to collect enough information to shape comprehensive software specifications.
