What does an AI email assistant do?

An AI email assistant can prioritize messages, summarize long threads, and draft replies. Swizero adds a fixed card limit, so those features lead to a completed email session instead of a faster infinite inbox.

Does Swizero send email automatically?

No. Swizero can prepare a draft, but every outgoing message requires your explicit approval. It never auto-sends on your behalf.

Does the AI read or store my Gmail?

Ranking happens on-device. When you request a summary or draft, zero-retention cloud processing generates the result without storing your email content or using it to train a model.

Does Swizero work with Outlook?

Swizero supports Gmail on iOS today. Outlook support is planned, so Outlook-only users should wait before choosing Swizero.

How much does Swizero cost?

Swizero Premium is $9.99/mo or $79.99/yr. Public access is currently invite-only through the waitlist.

A different job description

Writing is one step. Finishing is the outcome.

Most assistants wait for you to find the email, open the thread, and ask for help. Swizero starts earlier and ends later: it decides what belongs in the session, helps you act, and gives the session a visible end.

01Before you open email
Ranks what matters
On-device intelligence sorts your Gmail by urgency, sender, and context. You start with a handful of cards, not a chronological wall.
02When a reply needs you
Drafts with context
Swizero summarizes the thread and gives you a useful first draft. You review every word. Nothing sends without your approval.
03When the cards are clear
Stops at finished
A fixed card limit gives each Swizero Run an end. The assistant does not invent more work after you have handled what matters.

Answers for the way people actually search

Ask the whole question.

Short keywords hide the decision. These are the questions that reveal whether an AI assistant will actually help.

High-volume correspondence

“I’m drowning in client email. What AI assistant can help without sending the wrong thing?”

Choose an assistant that ranks first, drafts second, and keeps sending under human control. Swizero surfaces the client messages that need you, prepares a reply, and waits for your approval before anything leaves your inbox.

Triage before drafting

“What is the best AI email assistant if my real problem is sorting, not writing?”

Look for triage built into the workflow, not a writing box bolted onto an endless inbox. Swizero ranks every message on-device and turns the useful ones into a finite queue you can actually complete.

Privacy by separation

“Can an AI email assistant learn enough context without storing all of my email?”

It can separate local ranking from cloud generation. Swizero ranks on your iPhone; summaries and drafts use zero-retention processing, so email content is not stored or used for model training.

Designed to keep judgment human

Helpful without becoming reckless.

Email carries commitments, relationships, and private information. The assistant should reduce busywork without taking control away from you.

Read the privacy model

Ranking stays local

The prioritization step runs on your iPhone instead of sending your inbox away for sorting.

Generation retains nothing

Summaries and drafts use zero-retention processing. Email content is not stored or used for training.

Every send is deliberate

Swizero prepares the draft. You review it and make the final decision.

Your Gmail stays your Gmail

Swizero works on top of your existing account. It does not replace or lock away your inbox.

Swizero is a strong fit if

Your inbox is high-volume and the sorting is as painful as the replying.
You want AI drafts, but you want final approval on every send.
You need a visible finish line more than another power-user feature.
You use Gmail on iPhone and are comfortable joining an invite-only beta.

Get Early Access

Choose something else if

You need Outlook support today. It is planned, not live.
You want an assistant to send replies without reviewing them.
You need a desktop-first shared inbox for a support team.
You only want a writing generator and do not want your inbox workflow to change.
