Spiral
Spiral, a product from Every, uses stylometry to build a voice profile from your existing writing, then drafts tweets, blog posts, LinkedIn updates and newsletters in that voice. It adds shareable team styles, a knowledge base, and MCP and API access.
- Learning from samples sidesteps the fact that writers describe their own voice badly
- Stylometry is an established discipline rather than a marketing metaphor
- Shareable styles turn a brand voice document into something closer to a specification
- Format-aware generation avoids the obvious artefact of trimmed blog prose
- Captures how you write but not what you know, so drafts sound like you saying something generic
- A profile learned from past work preserves habits you may have been trying to lose
- Needs a decent body of existing writing, which rules out newer writers
