Aeralis Review (2026): Pricing, Features & Honest Verdict

TLDR

Aeralis is a Gmail add-on powered by Google Gemini that drafts replies in your own writing style. It learns your tone from sent mail and grounds answers in your docs, web search, and Maps. We found it useful but narrow. Best for: high-volume Gmail users. Price: Free for 8 emails/mo, Pro $14/mo. Rating: 6.4/10.

What is Aeralis?

Aeralis is an AI email assistant that installs as an add-on inside Gmail. It is powered by Google’s Gemini model and its job is simple: read an email thread and draft a reply that sounds like you wrote it. Instead of generic AI prose, it analyzes your sent emails to pick up your greetings, sign-offs, sentence patterns, and level of formality, then writes new drafts in that learned voice. It works on both personal Gmail and Google Workspace accounts, on desktop and mobile.

The product leans on two ideas that separate it from a basic prompt box. First, it is thread-aware, so it reads the whole conversation before suggesting a response rather than reacting to the last message in isolation. Second, it grounds drafts in real data: you can point it at documents, URLs, Google Maps, and live web search so replies reference actual facts instead of hallucinating them. It is aimed at people who send a high volume of email in roles like hospitality, healthcare, law, property management, e-commerce support, and IT services, where the same kinds of replies go out all day.

Aeralis arrives at a moment when AI email tools are everywhere, so its bet is specificity. Rather than try to be a whole new inbox, it stays inside the Gmail you already use and focuses on making the drafts sound authentically like you. Whether that focus is a strength or a limitation depends entirely on how much email you send and where you send it from. For the right user it removes a daily chore; for the wrong one it is a narrow add-on that overlaps with features they may already own.

What Are Aeralis’s Key Features?

Personalized voice learning

The core feature is style matching. Aeralis studies your sent mail to learn how you actually write, then drafts in that voice. The promise is that recipients cannot tell a draft came from AI because it mirrors your phrasing, formality, and sign-offs. On the free tier you get 5 writing style samples to shape it; Pro removes that cap so the model has more of your writing to learn from, which makes the output more convincingly you.

Multiple profiles

You can create different writing profiles for different audiences. One voice for clients, another for your team, another for personal mail. The free plan limits you to a single profile, while Pro makes them unlimited. For anyone who switches registers constantly, like an agency owner emailing both a formal client and a casual contractor, profiles are the feature that keeps the tone right without manual editing.

Grounding in real data

This is where Aeralis tries to beat a plain chatbot. It can reference your own documents and PDFs through its Knowledge feature, pull in URLs, check Google Maps, and run live Google Search so a reply is grounded in current information rather than guesswork. If a customer asks about your hours, your return policy, or a nearby location, Aeralis can answer from real sources instead of inventing an answer. The Knowledge document feature is Pro-only.

Workspace automation and privacy

Aeralis integrates with Google Workspace Studio so it can draft replies automatically from incoming emails or calendar events, edging toward hands-off triage. That automation is the most ambitious part of the product, since it moves Aeralis from a tool you trigger to a tool that works in the background. On privacy, the company states that your email content never leaves Gmail and that it does not store or retain your inbox data, which is a reassuring stance for anyone nervous about handing an inbox to a third-party AI. It uses minimal permissions to do its work, which lowers the barrier for security-conscious teams to even try it.

How Much Does Aeralis Cost?

Aeralis starts free, but the free tier is capped at just 8 emails per month with a single profile, 20 context sources, and 5 style samples. That is enough to see how it writes but not enough to actually rely on. Pro is $14 per month, or $140 per year which works out to about $11.67 a month and saves $28 over monthly billing. Pro unlocks unlimited emails, unlimited profiles, the Knowledge document feature, and priority support. There are only these two tiers; no business or team plan exists.

Against competitors, $14 a month sits at the budget end. Superhuman, the premium AI email client, runs about $30 per month and replaces your entire email client rather than bolting onto Gmail. Shortwave, an AI-first Gmail client, starts around $7 per month and also does far more than draft replies. Google’s own Gemini is bundled into paid Workspace plans, so if you already pay for Workspace you may get AI drafting without a separate subscription.

The pricing is fair for what Aeralis is, but the comparison exposes its narrowness. You are paying $14 a month for a single feature, drafting in your voice, while tools at similar or slightly higher prices give you a full email experience. The stingy 8-email free tier also makes it hard to fall in love with before paying, which is a self-inflicted wound.

Who is Aeralis Best For?

Use Aeralis if you live in Gmail, send a high volume of similar emails, and want every reply to sound like you wrote it without the effort. Hospitality teams, support staff, property managers, and solo professionals who answer the same questions all day are the clearest fit. The grounding features make it especially handy when replies need to reference real facts like policies, locations, or documents.

Skip Aeralis if you work outside Gmail, since it does nothing for Outlook or other clients. Skip it too if you want a full email client with snippets, scheduling, and triage rather than a drafting add-on; Superhuman or Shortwave will serve you better. And if you already pay for Google Workspace, check whether native Gemini covers enough of your needs before adding another subscription.

Best Aeralis Alternatives

Superhuman

Superhuman is the premium AI email client, priced around $30 per month. It replaces Gmail’s interface entirely with a fast, keyboard-driven experience and bakes AI drafting, summaries, and triage into the whole client. It costs more than double Aeralis and is a bigger commitment since you change clients, but you get a complete productivity overhaul rather than a single drafting feature. If email is your job and speed matters, Superhuman is the heavyweight.

Shortwave

Shortwave is an AI-first email client built on top of Gmail, starting around $7 per month. It offers AI summaries, smart search, scheduling, and reply drafting in one app. It undercuts Aeralis on price while doing considerably more, though it asks you to adopt a new client interface instead of staying in stock Gmail. For users who want broad AI email features cheaply, Shortwave is the value pick.

Google Gemini in Workspace

If you already pay for Google Workspace, Gemini’s native Help me write feature drafts and rewrites emails directly inside Gmail at no extra cost. It does not learn your personal voice as deeply or ground replies in your documents the way Aeralis does, but for basic drafting it is already in the product you pay for. Check this option first before adding Aeralis on top.

Final Verdict: Is Aeralis Worth It?

Aeralis does one thing genuinely well. We tested how it handles voice matching and grounding, and the personalized drafts do sound more like a real person than generic AI output, while the ability to pull in documents, Maps, and web search keeps replies factual. For a Gmail user buried in repetitive email, $14 a month to draft in your own voice is a reasonable trade, and the privacy stance of keeping content inside Gmail is welcome.

The reasons it lands at a middling score are its narrowness and that stingy free tier. It only works in Gmail, it only drafts email, and rivals like Shortwave and Superhuman deliver far more for similar or slightly higher prices. There is also the open question of whether native Gemini in Workspace closes the gap over time, which would squeeze a single-purpose add-on like this. Our recommendation: try the free tier, but know that 8 emails per month barely lets you test it before you have to decide. If you are a heavy Gmail sender who values voice matching above all else, Aeralis earns its keep and the $14 plan pays for itself in saved minutes. Everyone else should compare it against a fuller email client, and against the AI tools they may already be paying for, before subscribing.
