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
Merlin AI
One subscription spans GPT, Claude, Gemini and more in a side-panel, with best-in-class YouTube summarization.
- Many top models in one plan
- Generous free tier (~102 daily queries)
- Strong YouTube/article summarization
- Works on Gmail, LinkedIn, Search
- 'Unlimited' Pro is a fair-use credit cap
- Responses can feel watered-down vs native
- Chrome-only
- Closed source
