Best for autocomplete while you type in Chrome
Compose AI is a Chrome extension that finishes your sentences in any text box. The site says it is free forever, but the premium price couldn't be read, the site footer shows 2024, and it is Chrome only with no inbox of its own.
Who Compose AI is for
- Fits if you write in Chrome all day and want sentences finished for you
- Works for people who want a free trial of AI autocomplete before paying anything
Who Compose AI is not for
- Skip it if you want an email app, because it has no inbox and works only as a Chrome add-on
- Not for you if you use Safari, Firefox or a phone, as no other browser or app is mentioned
- Watch out: the premium price isn't on the page we could read, so you can't tell what upgrading costs
- Watch out: the site footer shows 2024 and the homepage mentions no recent updates
Why Compose AI gets a 2.4
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyThe extension is free, and a premium version exists, but its price sits behind a pricing page that wouldn't load. We can't say where it lands against the $8 email middle.
- BFree plan and trialThe site says the plugin is free to use forever, with a premium version adding personalization features. No card or time limit is mentioned.
- CFeaturesAutocomplete, text generation and style personalization. It is a general writing helper, not an email client, so there is no inbox, folders or sending.
- BEase of useNo store rating on record. Install the extension and start typing, with nothing to set up.
- CPlatforms and integrationsChrome only, according to the site. It names LinkedIn, Facebook and Instagram, and no API.

Keep Compose AI, or make your own?
Keep it
The plain part of Compose AI you could make: long-form writing. What surrounds it you could not. The 2 things listed below take a company, not a weekend.
What you could make
- Long-form writing: an app builder makes this well.
What you could not
- Text expansion that works in every app.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Compose AI’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Compose AI?
Compose AI is a Chrome extension that suggests text as you type and can generate drafts for emails, documents and chat messages. It says it learns the user's writing style to personalize suggestions. Its site describes a free version and a premium version, but the pricing page could not be read.
Worth knowing
- The pricing page loads its plans with JavaScript and could not be read, so no premium price is listed.
- It is a Chrome plugin; the site mentions no other browsers or standalone apps.
- The site footer shows a 2024 copyright, and the homepage mentions no recent updates.
- It is a general writing tool, not an email client: it has no inbox of its own.
Key features
- Autocomplete in any text field
- Suggests the rest of a sentence where you type, across the sites and tools the extension is allowed to run on.
- Text generation
- Generates text from a prompt, with emails, documents and chat messages named as example uses.
- Writing-style personalization
- The vendor says it learns the user's voice and suggests phrases in that style; the FAQ ties some personalization features to the premium version.
- Use-case pages
- Site pages cover copywriting, blogging, recruiting and social media posts, including LinkedIn, Facebook and Instagram.
