Pricing comparison

Aeralis and Superhuman sit at very different price points.

Aeralis pricing:

• Free -- 15 emails/month, 1 profile, Google Search and Maps grounding included
• Pro -- $14/month, unlimited emails, up to 5 profiles, context URLs, style learning
• Business -- $29/month, unlimited profiles, file search, all grounding tools
• Team -- $79/month (3 seats included), shared profiles, team analytics

Superhuman pricing:

• $30/month flat -- single tier for all features

The gap is significant. Aeralis Pro costs less than half of Superhuman at $14/month while offering features Superhuman lacks, like style learning and grounding tools. You can also start free and upgrade when you need more.

Superhuman's single-tier pricing is simpler but gives no flexibility. If you only need AI drafting help a few times a week, Aeralis's free tier covers that without spending anything.

Key differences

Different products, different goals

The most important distinction: Superhuman replaces your email client. Aeralis works inside it.

Superhuman is an entire email experience built around speed. It has its own interface, its own keyboard shortcuts, its own mobile app. When you adopt Superhuman, you leave Gmail's interface behind.

Aeralis installs as a Google Workspace Add-on and appears in your Gmail sidebar. Your inbox, labels, filters, and workflows stay exactly the same. You get AI drafting layered on top of what you already use.

AI capabilities

Superhuman added AI features to its speed-focused email client. The AI assists with writing and replying, but the core product is the fast email experience.

Aeralis is built around AI email generation from the ground up. Every feature serves that purpose:

• Style learning lets you forward sent emails so Aeralis picks up your greetings, sign-offs, and sentence patterns. Emails sound like you wrote them.
• Profile system gives you separate configurations for different contexts -- one for clients, another for internal comms, a third for personal email. Each profile has its own tone, instructions, and grounding settings.
• Grounding tools pull in real-time data from Google Search, Google Maps, context URLs, and knowledge bases so your drafts reference current information.

Speed vs. depth

Superhuman optimizes for inbox throughput. Split inboxes, keyboard shortcuts, read statuses, and snooze help you process email faster. The AI is one feature among many.

Aeralis optimizes for draft quality. Style learning, multi-profile support, and grounding tools ensure each generated email matches your voice and includes relevant context. It does one thing and goes deep.

When to choose Aeralis

You want emails that sound like you. Style learning analyzes your real sent emails and adapts to your writing patterns. No other tool in this comparison does this per-profile.

You use multiple contexts. Profiles let you switch between a formal client tone and a casual team tone instantly, each with its own system prompt and grounding settings.

You want to stay in Gmail. If you like Gmail's interface, labels, and workflows, Aeralis adds AI without disrupting anything.

Budget matters. Start free, move to $14/month for unlimited usage. Even the Business plan at $29/month costs less than Superhuman.

You need grounded, accurate drafts. Google Search, Maps, context URLs, and file search ensure your emails reference real, current information rather than relying solely on AI training data.

When to choose Superhuman

Speed is your priority. Superhuman is built around processing email as fast as possible. If you handle hundreds of emails daily and need to blast through your inbox, Superhuman's workflow optimizations help.

You want keyboard-driven workflow. Superhuman's extensive keyboard shortcut system lets power users navigate their inbox without touching the mouse. If that workflow appeals to you, it is well-executed.

You want a premium, unified experience. Superhuman provides a polished, opinionated email client with its own mobile app. If you prefer a curated experience over customizing Gmail, Superhuman delivers that.

AI is secondary to inbox management. If your primary problem is managing a high volume of email rather than writing better drafts, Superhuman's inbox features may be more relevant.

Verdict

These tools solve different problems.

Superhuman is for people who want a faster email client with AI features added on top. You pay $30/month for speed, keyboard shortcuts, and a premium interface that replaces Gmail.

Aeralis is for people who want better AI-generated emails while staying in Gmail. You get style learning, profiles, and grounding tools at a lower price point -- or free if your volume is light.

If your bottleneck is writing emails that sound like you and contain accurate information, Aeralis is the stronger choice. If your bottleneck is processing a high volume of email quickly, Superhuman may be worth the premium.

Most users who primarily need help drafting and replying to emails will get more value from Aeralis at a lower cost.

Frequently asked questions

Can I use Aeralis and Superhuman together? Not directly. Superhuman replaces the Gmail interface, and Aeralis is a Gmail add-on that requires the Gmail interface. You would need to choose one approach.

Does Superhuman offer style learning? No. Superhuman's AI generates drafts based on context and general instructions, but it does not learn your personal writing patterns from your sent emails the way Aeralis does.

Is $30/month worth it for Superhuman? It depends on your needs. If you process hundreds of emails daily and value speed above all else, Superhuman's workflow tools justify the cost for some users. If you primarily need help writing better emails, Aeralis Pro at $14/month provides more relevant AI features at less than half the price.
