What is Compose AI?

Compose AI is a Chrome extension that adds AI autocomplete to all text fields you use in your browser. You start a sentence in Gmail — Compose AI completes it. You write in a web form or a Notion doc — the AI suggests the rest. The principle is similar to GitHub Copilot but for general writing, not code. For professionals who write a lot of emails, docs or messages daily, the speed-up is real. The difference with ChatGPT: you don't have to switch tabs — the AI is where you write.

Strengths

Everywhere in Chrome without switching tabs

The writing speed-up is immediate because you don't interrupt your flow. You write, the AI completes.

Works in Gmail natively

For heavy Gmail users, the integration is smooth and the speed-up on repetitive emails is significant.

Usable free plan

The free plan offers a monthly autocomplete quota sufficient to evaluate the product.

Limits

Completions sometimes off-context

The autocomplete can sometimes go in an unexpected direction. Adapting tone and context takes a few tries.

Competition from native features

Since 2024, Gmail, Notion and other tools integrate their own AI. Compose AI loses relevance against native features.

Pricing

Free plan with limited quota. Paid plan at $10/month. Check compose.ai/pricing.

Alternatives

Compose AI = Chrome AI autocomplete. Alternative Grammarly (grammarly.com) = correction + tone + AI, $15/month. Alternative Hyperwrite (hyperwriteai.com) = $20/month, AI agent included. Native Gmail AI = free with Google Workspace.

Verdict

Compose AI is useful if your main writing tool has no integrated AI. But with the acceleration of native AI features in Gmail, Notion and Office, the value proposition shrinks.
