Just say it out loud.

One sentence is enough. She sees what's on your screen and takes whatever you drop on her, so you never have to explain the setup.

  • Mail

    She finds it in your inbox, reads the mail and the attachment, and tells you the gist out loud. A reply goes out only after you've seen it.

    Read me the quote the client sent last week.

  • Look

    She sees the window you're in. No copying, no explaining — she takes it from your screen and hands back a file.

    Put the numbers in this table into an Excel sheet.

  • Write

    Drop in your notes and tell her the format. The finished doc comes back as a card you can open or drag out.

    Turn these bullet points into a one-page brief, as a Word doc.

  • Do

    Drop the contract on her and say it. She reads it, pulls out what matters, and writes it into your Notes while you keep working.

    Turn this contract into three bullet points and save them to Notes.

  • Web

    She works in her own browser on your Mac, or right in your Chrome through the Nico extension. Sites see your usual network and your existing login, so they treat her like you.

    Grab last month’s invoices from the supplier portal.

  • Watch

    She checks it for you and only speaks up when there's something new. Folders and your calendar work the same way.

    Keep an eye on this jobs page and tell me when a new role appears.

Or say nothing at all.She'll bring it up.

Nothing to set up. She remembers what you've said, and knows when it's worth bringing up.

Don't type. Just say it.

Hold the right ⌘, say what you need, and let go. Speaking is about three times faster than typing, and your hands never leave what you’re doing.

The same request, typed vs. said

Typed≈ 32 s
Said≈ 8 s

The request in the bubble is 21 words, estimated at 40 words a minute typed and 150 spoken.

Your words show up in her bubble as you speak and stay there after you let go, so you can see what she heard.

One Nico Two agents.

Nico is made of two agents. One stays out front and answers you right away. The other works behind the scenes, getting things done and looking things up.

Out front

Nico talks with you

Quick and always there. She works out what you need, hands the job to the Worker, and tells you how it went. Before the Worker sends, submits or deletes anything, she checks that step against what you actually asked. Mail and payments still wait for you. Even while a long job runs, she’s free to talk.

Runs on Nico’s own voice service, with Nico Plus.

Behind the scenes

The Worker gets it done

A desktop work agent, the kind everyone’s talking about. It plans, researches, works with your files, the web, your mail and your apps, makes what you asked for, and checks its own work. All on your Mac, inside a sandbox.

Inside the Worker is pi, an open-source agent harness: a small, readable loop that talks to the model, runs the tools it asks for, and already speaks to every provider below. We’ve read a lot of agent code. This is the one we’d build on, so we did. The tools, the check before every action, and the sandbox are Nico’s own. pi on GitHub

Runs on your own AI subscription.

Bring the AI subscription you already have.

The Worker runs on it. Most AI providers work: sign in with your account, or paste the key from your coding plan or API account.

Credentials stay on your Mac.

She lives on your Mac,not on a cloud computer

Many personal agents now work on a virtual computer in the cloud. You upload your files, sign in again over there, and download whatever it makes. Nico lives on your Mac, where your files, accounts and apps already are.

How shekeeps your secrets

Three things make that true: what you say to her is never stored, the Worker runs on your own AI account, and everything she makes stays on your Mac.

Nothing you say to her is kept. Anywhere.

What you say to Nico, by voice or by typing, is handled with zero data retention. Nico’s relay has no database: it passes your words along and keeps nothing, and its logs hold only numbers like timing and usage. The model provider doesn’t keep them or train on them either.

  • The Worker never touches Nico’s servers

    It talks straight from your Mac to the AI provider you picked, with your own account, under that provider’s privacy terms. Nico has no copy of what it reads or writes.

  • Everything stays on your Mac

    Memories, chat history and what she makes are files on your Mac. Credentials go into your Keychain. There is no cloud computer holding a second copy.

  • The mic is on only while you hold the key

    Let go of the right ⌘ and the mic closes. When she glances at your screen, the screenshot stays in memory and is never saved.

  • Nothing irreversible without you

    Before anything that can’t be undone or that involves money, she stops and asks. She goes ahead only after you approve.

Get to know Nicoin three steps

  1. Install

    Open the DMG and drag Nico into your Applications folder.

  2. Follow her checklist

    The first time you open her, she pins a checklist beside her: allow the microphone and Input Monitoring, tell her what to call you, and connect your AI account.

  3. Say hi

    Hold right ⌘, say hi, and let go. She'll answer.
