The honest brief
Compose AI
Lives inline as autocomplete wherever you type — Gmail, Docs, the web — rather than a separate chat window you copy answers out of.
- Inline autocomplete anywhere you type
- Drafts full emails from one instruction
- Free core tier
- Custom text-expansion shortcuts
- Chromium browsers only
- Best for short-form writing, not long docs
- Personalization features gated to premium
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
