You spend hours every week writing emails. Follow-ups, client updates, cold outreach, replies to long threads, it adds up fast. AI writing tools promise to fix that. But not all of them work the same way, and picking the wrong one means you're still wasting time.

Foresty and Compose AI are two popular Chrome extensions that help you write faster. On the surface, they look similar. Dig deeper and the differences become clear, especially if email is where you spend most of your time.

This article gives you a complete, honest comparison of both tools: features, pricing, use cases, and a clear verdict on which one fits your workflow.


What Is Foresty?

Foresty is an AI-powered Chrome extension built exclusively for email. It plugs directly into Gmail and Outlook, letting you draft, reply to, improve, and send professional emails, all without leaving your inbox.

Think of it as having a writing assistant sitting right inside your compose window. You describe what you want to say, and Foresty turns it into a polished, ready-to-send email in seconds.

Edit any emails easily from Gmail

It's powered by AWS Bedrock and processes everything securely over HTTPS. Your email content is never stored, never used to train AI models, and never sold to third parties.

Key Features of Foresty

✓

AI Email Draft Generation

Describe your message in a few words, and Foresty writes the full email for you.

Who Is Foresty Built For?

Foresty is designed for professionals who live in their inbox. That includes:

  • Sales executives: writing follow-ups and outreach emails all day
  • Customer success managers: handling high-volume client communications
  • Recruiters: sending candidate and hiring manager emails
  • Startup founders: managing investor updates and partner outreach
  • Executive assistants: drafting emails that require precise tone for leadership
  • HR managers: handling sensitive employee communications
  • Freelance consultants: managing client correspondence

If your daily workflow involves Gmail or Outlook and you're tired of spending 20+ minutes crafting emails, Foresty is built for you.


What Is Compose AI?

Compose AI is a free Chrome plugin that acts as a universal AI writing assistant, not just for email, but across all the tools you use in your browser. Its core strength is AI-powered autocomplete, which works on any website or platform you type on.

Instead of generating full emails from a prompt, Compose AI focuses on predicting and completing your sentences as you write. It learns your writing style over time and suggests personalized phrases to help you write faster.

Compose AI claims to reduce writing time by 40% by speeding up the act of typing itself, rather than generating content from scratch.

Who Is Compose AI Built For?

Compose AI appeals to a broader audience: anyone who types frequently across multiple tools and wants intelligent autocomplete to speed up that process. It's particularly useful for:

  • Writers and content creators who draft content across multiple platforms
  • Professionals who type heavily across tools like Docs, Notion, or Slack
  • Users who prefer a subtle, suggestion-based writing experience over full AI generation
  • People looking for a free, lightweight writing assistant without a subscription

Foresty vs Compose AI: Side-by-Side Comparison

Content Creation Capabilities

Foresty is purpose-built for full email creation. You give it a rough idea, a few bullet points or a sentence, and it generates a complete, professional email. That includes the opening, body, closing, and even the subject line.

Compose AI does not generate full emails. It speeds up your writing by predicting your next word or phrase. It is more like an intelligent autocomplete than a content generator.

If you need to go from a blank compose window to a ready-to-send email in under 3 minutes, Foresty is the clear winner here.

AI Writing Assistance

Both tools assist your writing, but in very different ways.

Foresty actively does the writing for you. It reads the context of an email thread, understands what is needed, and generates a reply that sounds natural and professional. It also improves existing drafts, fixing grammar, adjusting tone, and polishing sentences with a single click.

Compose AI enhances your writing by predicting what you are about to type. It is helpful for speeding up the mechanics of writing, but it does not understand email context or generate structured, purposeful responses on your behalf.

Ease of Use & Interface

Foresty lives inside the Gmail or Outlook compose window. You don't move between tools, you don't copy-paste, you don't open a new tab. Everything happens where you are already working.

Compose AI is similarly lightweight and unobtrusive. Its autocomplete suggestions appear inline wherever you type. The learning curve is minimal for both tools.

The key difference: Foresty requires you to consciously activate it when you want a draft or improvement. Compose AI runs passively in the background and suggests completions as you type.

Integrations & Compatibility

IntegrationForestyCompose AI
Gmail Deep integration Basic
Outlook (incl. 365 & Web) Full support Not supported
Google Docs No Yes
Slack No Yes
Notion No Yes
Any Website No Yes

Foresty wins on depth within email. Compose AI wins on breadth across tools.

If you use Outlook, Foresty is the only option: Compose AI does not support it.

Customization & Personalization

Foresty preserves your natural writing voice. Its AI outputs are designed to sound like you, not like a generic AI response. It understands the tone and context of the email thread before generating a reply.

Compose AI builds a personalized model of your writing style over time, using your previous writing to suggest phrases that match how you communicate. This is powerful for long-term users but takes time to develop.

Pricing & Plans

Plan DetailsForestyCompose AI
Free Plan500 words/monthFree (indefinitely)
Entry Paid Plan$8.08/mo (annual) / $12.95/mo (monthly), 15,000 wordsPremium tier (pricing varies)
Power Tier Plan$21.41/mo (annual) / $29.95/mo (monthly), 50,000 words—
Credit Card Required No No
Outlook Support Yes No

Foresty's pricing plans are transparent with no hidden fees. The Basic plan ($8.08/month billed annually) gives you 15,000 words per month, enough for most professionals handling regular email volume.

Compose AI's free tier is generous, but its premium features come at a cost that is not publicly fixed.


Where Foresty Stands Out

Purpose-Built for Email, Not a Generic Tool

Foresty does not try to do everything. It does one thing extremely well: help you write better emails, faster.

Every feature, the reply generator, the subject line creator, the voice assistant, the inline editor, is designed around the email workflow. That focus matters. When a tool is built specifically for email, it understands email context, email tone, and email purpose in a way a general-purpose writing tool simply cannot.

The result? Foresty reduces email writing time from 20–30 minutes down to 2–3 minutes. That is not a marginal improvement, it is a full workflow transformation.

Outlook Support & Enterprise Privacy Standards

Most AI writing tools focus exclusively on Gmail. Foresty fully supports Microsoft Outlook, including Outlook 365 and Outlook Web, making it the stronger choice for teams and professionals inside Microsoft ecosystems.

On the privacy side, Foresty sets a high standard. Email content is never stored, never used for model training, and never sold. Everything is processed in-memory via AWS Bedrock and discarded immediately after your response is returned. For professionals handling sensitive client, legal, or HR communications, this matters enormously.

You can read more about Foresty's data handling in its Privacy Policy.


Where Compose AI Stands Out

Works Everywhere, Not Just Email

Compose AI's biggest advantage is its universal compatibility. It works across every platform you type on: Google Docs, Notion, Slack, LinkedIn, web forms, chat tools, and more.

If your daily writing spans multiple tools beyond just email, Compose AI's autocomplete follows you everywhere. Foresty stays inside your inbox.

The Free Plan Is Truly Free

Compose AI's free plan has no time limit and no credit card requirement. For users who only need lightweight writing assistance and cannot commit to a paid subscription, this is a meaningful advantage.

Foresty's free plan is also no-credit-card required, but it is capped at 500 words per month, which suits trial usage more than ongoing daily use.


Use Case Scenarios: Which Tool Should You Choose?

Choose Foresty If…

  • ✓You spend a significant portion of your workday in Gmail or Outlook
  • ✓You need to generate full, polished emails from scratch in seconds
  • ✓You want context-aware AI replies that understand your email thread
  • ✓You use Microsoft Outlook and need AI writing support there
  • ✓You handle sensitive communications and need confirmed data privacy
  • ✓You want a dedicated AI email reply generator built specifically for email
Example: A sales executive sending 40+ emails a day switches to Foresty and cuts email time from 25 minutes to under 5 minutes. That is 2+ hours saved daily, without leaving Gmail once.

Choose Compose AI If…

  • ✓Your writing is spread across many tools, not just email
  • ✓You prefer subtle autocomplete over full AI-generated content
  • ✓You want a completely free option with no word cap
  • ✓You write heavily in Google Docs, Notion, Slack, or similar platforms
  • ✓You're comfortable with a tool that learns your voice gradually over time
Example: A content strategist who drafts in Google Docs, communicates in Slack, and only occasionally writes emails might get more value from Compose AI's universal approach.

Final Verdict

Both Foresty and Compose AI are solid tools. But they serve fundamentally different needs.

Compose AI is a broad, general-purpose writing accelerator. If you type across many platforms and want a free, always-on suggestion layer that adapts to your style over time, it is a capable pick.

Foresty is a specialist. It is built from the ground up to handle email, and it handles email better than any general-purpose tool can. Full draft generation, context-aware replies, subject line creation, voice input, inline editing, Outlook support, and enterprise-grade privacy, all without leaving your inbox.

Foresty turns a 20-minute task into a 2-minute one. That is not an incremental improvement; it is a different way of working entirely.


Frequently Asked Questions (FAQ)

Is Foresty better than Compose AI?

It depends on your workflow. For email-heavy professionals using Gmail or Outlook, Foresty is the stronger tool: it offers full email generation, AI replies, subject lines, voice input, and inline editing, all purpose-built for inbox use. Compose AI is better if you need a lightweight autocomplete tool that works across many platforms beyond email.

Can I use Foresty and Compose AI together?

Yes, technically you can run both Chrome extensions simultaneously. However, since they serve different purposes, most users find they naturally prefer one depending on where they do most of their writing. Foresty handles everything email-related; Compose AI can supplement writing in other tools.

Which tool is better for SEO content?

Neither tool is designed for SEO content creation. Compose AI's universal approach makes it slightly more relevant for content writers working in Docs or CMS platforms, since it works outside of email. For SEO writing, a dedicated long-form AI tool would serve you better. For email outreach as part of an SEO or content workflow, Foresty is the clear choice.

Which tool offers better value for money?

Foresty's Basic plan at $8.08/month (billed annually) gives you 15,000 words per month, full email generation, AI replies, voice assistant, and priority support, all within Gmail and Outlook. For professionals who rely on email, that ROI is significant. Compose AI has a generous free tier, but if you need full AI generation capabilities (not just autocomplete), Foresty delivers considerably more value at its price point.

Does Foresty store my emails?

No. Foresty processes your email content in-memory for the duration of your request and discards it immediately after. Nothing is stored permanently, nothing is used for AI model training, and nothing is sold. Full details are available in Foresty's Privacy Policy.

Does Compose AI work with Outlook?

No. Compose AI does not support Microsoft Outlook. If your email workflow runs on Outlook, including Outlook 365 or Outlook Web, Foresty's Outlook Writing Assistant is currently one of the only dedicated AI tools built for it.

How long does it take Foresty to generate an email reply?

Foresty generates email replies in 30 to 60 seconds. By comparison, writing a reply manually takes 10–20 minutes, and using ChatGPT with copy-pasting takes 5–10 minutes. Foresty is built for speed, inside your inbox, with no extra steps.
