Prologue

Prologue (Prologue AI) is a multimodal creative operating system that lets teams create, edit, and organize AI-generated images, video, audio, and text in a single workspace. Powered by "Prologue Intent" and a best-in-class catalog of third-party generative models, it targets professional creative workflows for agencies and brands ("crafted, not generated"). It was surfaced as an a16z portfolio company and added to the API Evangelist network as a stub for enrichment. As of this pass no public developer API, documentation, or SDK surface was discoverable — the product site is a consumer/pro web application behind bot protection.

Prologue is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Generative AI, Creative Tools, and Content Creation.
