Spiral is an AI writing partner designed to help individuals, marketers, teams, and their AI agents create content that reflects a distinctive voice. Developed using Every’s editorial knowledge and standards, the product applies stylometry—the analysis of linguistic patterns—to identify characteristics such as sentence length, word choice, punctuation, and writing structure. Users can provide writing samples, brand documents, published content, or connected social channels so Spiral can map their voice and build custom styles for consistent use across formats and channels.

The platform supports live writing with an AI agent, multiple drafts, real-time feedback, and editorial direction. It can help produce on-brand copy for social media, blogs, ads, and other uses, while offering guidance on adapting content for formats such as tweets, articles, and LinkedIn posts. Spiral is designed to reduce the need for prompt engineering by applying learned style patterns directly to drafts. It is available as part of Every’s bundle, which is listed at $30 per month and also includes AI analysis, courses, and software.
