What is Spiral?
Spiral is an AI writing partner from Every that learns your voice from samples and drafts on-brand posts, emails and essays. Every is the media company behind a newsletter about AI and several AI apps, and Spiral is used internally there for published work. Writers such as Lenny Rachitsky and Emily Oster have praised it.
Spiral's difference is stylometry, the measurement of writing style. You give it samples of your writing, brand documents or connected social channels, and it builds styles that capture your sentence length, word choice and openings. Rather than producing text immediately, it asks what you are trying to say and offers several drafts. It also connects to Claude Code, Cursor and ChatGPT over MCP so drafts your agents write come out in your voice. Use cases include social posts, newsletters, landing pages, presentations and meeting recaps.
