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 MailMaestro if
- Fits if you answer lots of similar emails in Outlook or Gmail
- Works for teams that want shared templates and one bill, from two seats up
Look elsewhere if
- Tight if you stay free: 3 AI requests a week runs out by Tuesday
- Pricey if you want inbox agents, labels and follow-ups, which are Pro-only at $12 a seat
- Skip it if you want a full email client, as it only adds to Outlook and Gmail
- Watch out: annual plans can't be refunded after purchase, according to the pricing FAQ
- Watch out: the name is in flux, as Flowrite was folded into MailMaestro and its old team moved to a separate product
How we grade them
| 2.4GPACompose AIFair | 2.0GPAMailMaestroFair | |
|---|---|---|
| Value for money | CThe 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. | CPro is $12 a seat a month on annual billing ($15 monthly), which sits near the dear end of email tools: the middle is about $8 and the cheaper quarter starts at $3. |
| Free plan and trial | BThe site says the plugin is free to use forever, with a premium version adding personalization features. No card or time limit is mentioned. | CFree forever with no card, but only 3 AI requests a week. That's a taste, not a plan you can work on. The Pro trial is 14 days. |
| Features | CAutocomplete, text generation and style personalization. It is a general writing helper, not an email client, so there is no inbox, folders or sending. | CWrites, replies, rewrites and summarizes, with templates and shortcuts. It lives inside Outlook and Gmail, and the listing shows no standalone client. |
| Ease of use | BNo store rating on record. Install the extension and start typing, with nothing to set up. | CNo store rating on record. You add it to your mailbox and connect your account, then learn the templates and shortcuts. |
| Platforms and integrations | CChrome only, according to the site. It names LinkedIn, Facebook and Instagram, and no API. | CA browser and Outlook add-in for one job, with Teams, Zoom and Google Meet listed. No phone or desktop app of its own. |

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.
- The differences and the answers to the questions are worked out from those listings.
