7 Best Gmail Smart Compose Alternatives in 2026 (More Powerful AI Writing)
Gmail Smart Compose only finishes sentences. These 7 Gmail Smart Compose alternatives write full drafts, learn your voice, and handle replies — most work inside Gmail.
TL;DR: Smart Compose is fine for finishing a sentence you started. It can't write a whole email, doesn't learn your voice, and has no idea what thread you're replying to. If you want a tool that actually drafts for you, you have a few options. Help me write is Google's own upgrade, bundled with Workspace Business Standard at $14/user/month. Aeralis is $14/month with a free tier and adds style learning. Fyxer ($22.50/month annual) is similar but as a Chrome extension. Shortwave ($9/month) replaces Gmail with an AI-first client if you're up for a client switch.
Why look for Smart Compose alternatives?
Smart Compose is Google's built-in AI writing feature in Gmail. It's been around since 2018 and works well for finishing a sentence you've already started.
The limits show up fast once you want more:
- It only suggests phrase-by-phrase completions, never full drafts
- Same suggestions for everyone — no adaptation to your writing style
- Can't use the email thread you're replying to as context
- Help me write is more capable but gated behind Workspace Business Standard or higher, and still produces generic drafts
- No control over tone, voice, or sources
If you're looking for something that writes full drafts, understands thread context, or sounds like you — here's what actually works.
What makes a good Smart Compose alternative
Before picking one, worth thinking about what you need:
- Full drafts, not just phrase completions
- Reply generation that reads the email you're replying to
- Style learning — drafts that sound like you, not generic AI
- Integration depth — works inside Gmail without another tab
- Justifiable price vs. Smart Compose being free
1. Aeralis (recommended)
Aeralis is a Google Workspace Add-on. It generates full drafts and replies inside Gmail, reads the entire thread when you're replying, and writes in the voice it learns from your forwarded sent emails.
The parts that matter coming from Smart Compose:
- Full drafts from a prompt, not just sentence completions
- Reply generation that uses the whole thread for context
- Style learning — forward three sent emails to activate a profile, the AI picks up your voice
- Multiple profiles for different audiences (client emails, internal comms, sales, personal)
- Grounding on real data — context URLs, Google Search, Google Maps, document uploads
- Free tier: 15 emails/month, no credit card
- Pricing: $14/month Pro, $29/month Business
Best for: anyone who wants full AI drafts inside Gmail without learning a new interface.
2. Gmail "Help me write" (Gemini)
Google's own upgrade to Smart Compose. It generates full drafts from a prompt, built directly into Gmail's compose window.
Worth considering if your organization already pays for Google Workspace Business Standard ($14/user/month) or higher — Help me write is included. Limits: drafts feel generic, no style learning, no profile system, no grounding on your own documents.
3. Fyxer AI
Chrome extension for Gmail. Writes drafts in your voice using your sent emails as training data, and bundles meeting transcription.
Consider if you want email writing plus automatic meeting notes in one subscription. Pricing: $22.50/month on annual billing.
4. Superhuman
Replaces Gmail entirely with a premium email client. AI features include drafts, replies, and thread summaries.
Consider if you want a high-end email experience and are willing to pay $30/month. Note: requires switching clients, which is a bigger change than any of the above.
5. Shortwave
AI-first email client that also replaces Gmail. Features include drafts, summaries, semantic search across your inbox history, and smart labels.
Consider if you want to move away from Gmail's interface. Pricing: $9/month Personal, $40/month Business.
6. Compose AI
Free Chrome extension offering Smart Compose-style completions plus full drafts. Closer to Smart Compose in style — completions as you type — but with more capability.
Consider if you want a free, basic upgrade to Smart Compose with optional paid full-draft features.
7. ChatGPT or Claude (manual workflow)
If you already have ChatGPT Plus or Claude Pro, you can paste email context and ask for drafts. No integration, but the capability is there.
Consider if you write emails occasionally and don't need a dedicated tool. Downside: copy-pasting between tabs every time. If you write a lot of email, the tab-switching tax adds up fast.
How each compares to Smart Compose
| Feature | Smart Compose | Help me write | Aeralis | Fyxer | Superhuman |
|---|---|---|---|---|---|
| Full drafts | No | Yes | Yes | Yes | Yes |
| Reply with thread context | No | Limited | Yes (full) | Yes | Yes |
| Style learning | No | No | Yes | Yes | Limited |
| Multiple profiles | No | No | Yes | No | No |
| Inside Gmail | Yes | Yes | Yes (add-on) | Yes (extension) | No (replaces) |
| Starting price | Free | Bundled w/ Workspace | Free | $22.50/mo | $30/mo |
| Free tier | Yes | No (paid Workspace) | Yes | No | No |
Which one should you actually pick?
Want free AI drafts inside Gmail? Aeralis free tier — 15 emails a month, no credit card.
Already pay for Workspace Business Standard or higher? Use Help me write; it's included. Add Aeralis only if writers specifically want style learning.
Want full drafts plus meeting notes? Fyxer AI.
Want a premium email client? Superhuman or Shortwave — different flavors.
Only write emails occasionally? Just use ChatGPT or Claude with copy-paste. Not elegant, but free.
For most Gmail users who want better AI email writing without paying for Workspace Business Standard or leaving Gmail, Aeralis is the closest match to "Smart Compose, but actually good."
The real gap Smart Compose has
Smart Compose is a completion engine — it predicts the next few words based on what you've typed. Fast, free, useful for short completions.
Modern AI email tools are generation engines. You give them a goal ("write a reply to this email declining the meeting politely") and they produce the full email. Most also learn your writing style so the output doesn't sound like a bot.
Smart Compose won't write emails for you. Tools like Aeralis, Fyxer, or Help me write will. The decision is about which trade-offs you want — price, integration depth, style learning, how much of your workflow you're willing to change.
