Spiral

What it does

Spiral is a writing tool made by Every. It builds a writing style from samples you provide and applies that style to drafts across channels. It connects to Claude Code, Cursor, or ChatGPT over MCP so drafts written by an agent keep your voice. A personal plan is $15 per month, a team plan is $25 per user per month, and a bundle that adds other Every apps is $30 per month. Sign-up and the dashboard are at app.writewithspiral.com.

Spiral's style engine uses stylometry, the analysis of patterns such as sentence length, punctuation and word choice. Users can upload brand documents or connect social channels, and teams can share styles. The tool supports multiple drafts at once with feedback during writing. Listed uses include copywriting, social media, meeting recaps, newsletters, presentations and brand marketing. Spiral is sold on its own or in an Every bundle with Cora, Monologue, Sparkle and Proof.
