Which one is for you
Pick Compose AI if
- 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
Look elsewhere if
- 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
Pick Ellie if
- Fits if you spend your day answering inbound email in Gmail or Outlook
- Makes sense if a small team wants shared roles and one knowledge base for replies
Look elsewhere if
- Not for you if you write cold or outbound email, because the FAQ says it only replies
- Tight if you stay on Casual: 25 replies a day, extension only, no auto-drafts
- Pricey if you add people, as extra team members start at $5 each on top of the plan
- Skip it if you want a free plan, since there is only a 7-day trial
- Watch out: the pricing page shows a time-limited first-year discount that we haven't recorded

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
