5 Best Free Compose AI Alternatives for Email in 2025
Use these Compose AI alternative and email generators to write professional emails and responses in 2025.
Writing emails can feel like a chore, especially when you're busy, unsure how to say something, or just staring at a blank screen.
That's why so many people are turning to AI email generators to save time and get unstuck. They help write new emails and generate responses to existing ones.
If you’ve tried Compose AI and feel like it’s not quite the right fit, there are other options that might work better.
In this article, we'll list the 5 best free Compose AI alternatives for email in 2025. Let's dive in!
What is Compose AI?
Compose AI is an AI writing tool that helps users write emails and other content directly in their browser. It works as a Chrome extension that suggests sentences, rewrites messages, and finishes emails as you type.
It's useful, but there are other AI tools and alternatives out there that might work better for you.
Is Compose AI Free?
Compose AI offers a free plan, but it only includes 1,500 words per month (as well as other limitations). To get more access to AI email writing features, you have to upgrade to a paid plan.
If you need more control or better formatting tools, you might hit a wall with the free tier. That’s where looking for a Compose AI alternative can help.

Why Use AI Email Generators?
If you're tired of spending too much time writing emails or unsure how to word things clearly, you're not alone. AI email generators are designed to speed things up and take the guesswork out of common writing tasks.
Here are the benefits of using an AI email generator:
Save time writing daily emails - You can draft replies, intros, and follow-ups faster without starting from scratch each time.
Improve clarity and tone - The tools help you rephrase or adjust tone so your message sounds more natural or professional.
Sound more professional in your writing - AI tools help you avoid awkward phrasing, grammar issues, or overly casual language.
Get unstuck when you're unsure what to say - AI suggestions help you start or finish an email when you're staring at a blank screen.
Reply faster in your inbox - Some tools even work directly in Gmail or Outlook so you can generate replies without switching tabs.
If you regularly write or respond to emails, an AI writing tool can help you communicate faster, clearer, and with less mental effort.
How to Choose a Compose AI Alternative
If you're switching from Compose AI, it's important to know what features actually matter for writing emails faster.
Here’s what to look for based on how you write, where you work, and what kind of support you need:
Platform Compatibility
Make sure the tool works where you do—Gmail, Outlook, LinkedIn, or inside CRMs. A Chrome extension is useful if you want to write directly in your browser.
If it only works in a separate editor, you’ll waste time switching back and forth. Choose something that fits into your workflow.
Tone and Style Controls
You don’t want every email to sound the same. Look for tools that let you choose the tone—formal, casual, friendly, etc.—or rewrite messages based on your goals.
This helps you sound more natural and professional. Good customization keeps the AI writing flexible.
Smart Editing and Rewrite Options
The ability to proofread, rewrite, shorten, or expand messages is key for fast editing. Some tools show you what’s changed so you can compare drafts easily.
This helps you quickly fine-tune your message without starting over. If you often revise emails, this feature makes a big difference.
Value in the Free Plan
Some tools offer free versions with useful features, while others limit you after a few uses. Know what’s included before you commit.
If you write a lot of emails, you’ll want something that doesn’t cut you off too soon. Look for a plan that gives you enough to use it regularly without hitting a wall.
