The honest brief
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
Wordtune
From AI21 Labs (Jurassic/Jamba models) — a rewriting tool whose maker owns its own LLMs, not a GPT wrapper.
- Tone-controlled rewriting
- Article and video summarization
- Gmail and Slack integration
- Browser, web and iOS
- AI-text humanizer
- Narrower than full writing suites
- Free tier rewrite limits
- Less grammar depth than Grammarly
- No Android app
