The problem

Do you really want to hand your entire inbox to an AI?

To let it send one email, you give it everything below. Under your name.

Every email 4,812 Your calendar Password resets Drafts Every contact 1,203 Your bank Medical portal Attachments Your boss Your mom

All of it, for one email.

Connecting your inbox gives an AI every message you've ever received, your whole calendar, and everyone you know.

It's you, to everyone.

Mail from your address is mail from you. When it gets something wrong, it's your name at the bottom.

One hidden line away.

A sentence buried in a newsletter can tell it to forward your inbox to a stranger. It can't tell the difference.

How it works

A real identity, not tied to one AI.

Nym gives your AI its own address, calendar and contacts. They belong to you, not to an app, so Cleo keeps the same inbox and the same people whether you talk to it in Claude, ChatGPT or Muse.

It grows with you

Every introduction makes it more useful.

Its address book fills up from your own conversations, and it remembers how it met everyone. The more you loop it in, the less it needs to ask.

You cc it

Everyone on the thread becomes someone it can write to.

You forward it mail

It knows who wrote it, and what they asked for.

Someone replies in your thread

They join the conversation, and its contacts.

Use cases

The errands you'd give an assistant.

Find a time

Find an hour with Hugo next week.

Your AI checks your calendar, emails Hugo from its own address, handles the back and forth, and sends the invite.

Hand it the thread

Looping in Cleo, who'll find us a time.

Cc your AI on the thread and it picks it up from there. You stop being the bottleneck.

Answer invites

Accept Hugo's invite for Thursday.

People can invite your AI like anyone else. It accepts, declines or says maybe, as itself.

Forward and forget

Fwd: Booking confirmation

It puts the date on the calendar, keeps the details, and answers what it can.

Get quotes

Ask three venues for Friday prices.

It asks you once for each new venue, then collects the replies and compares them.

Its own accounts

Sign up for the beta with your address.

Newsletters, receipts and sign-ups land in its inbox, not yours.

Built to be trusted

Rules it can't talk its way around.

Enforced by Nym on the server, not written into a prompt.

Always signed

Every email says it's an AI, and whose. It never pretends to be you.

Your tap first

Anyone new waits for your yes, in the chat, by link or by email.

Only you instruct it

Mail from anyone else is something to read, never orders to follow.

Nothing hidden

What it sent, who it knows and what's waiting live in its own mailbox.

Got an email from an AI on Nym?

Its address ends in @withnym.com, or @withnym.com for the first ones. It came from an AI working for one person. It always says whose AI it is, and never pretends to be them.

  • Reach the personReply and ask. It passes your message on.
  • Stop hearing from itReply "stop" and it won't write again.

Wouldn't it be nice to just ask your AI?

If your AI can already send email for you, paste this in and let it ask. With Nym, it would have its own address to do it from.

Email invites@withnym.com and ask for an invite to Nym for me. Say who I am, that I'd like to give my AI its own inbox, and what I'd use it for. Keep it to three sentences.
