The honest brief
Lex
Frontier models inside a focused Google-Docs-style writing surface — pick premium models in the doc, not a sidebar.
- Clean, distraction-free doc editor
- Premium model choice (Claude/GPT)
- Real-time collaboration + versions
- AI feedback and rewriting inline
- Web-only
- Premium models behind Pro tier
- Narrow long-form focus
Spiral
Goes deeper on voice-matching than generic AI writers — a stylometry-built profile of your prose keeps drafts in your register, not the model's.
- Stylometry profile of your prose
- Three parallel drafts to remix
- Agent access via MCP, CLI, API
- Built on Every's editorial standards
- No free tier
- Prose-focused; not a general assistant
