Nico

Key facts: Nico launched on Hacker News on November 5, 2026. It is a voice-to-action personal agent for Mac that lives on your screen, hears what you ask, sees what you see, and does the work on your device: no cloud computer. Drop a PDF on her and ask why a bill is high, tidy the Desktop (and undo it with one sentence), get a spreadsheet back from a table on screen, have her answer an email (only after you have seen the reply), file an expense from a Chrome receipt, or find a table for team dinner. She remembers your plans, deadlines and people, and watches folders, your calendar and pages, speaking up only when something is new.

Plans: Free to download. It runs on the ChatGPT or Claude subscription you already have.

Best for: Mac users who already pay for ChatGPT or Claude and want an agent that acts on their screen. Who should skip it: anyone on Windows, or who does not have a ChatGPT or Claude subscription.

Pros

• Free to download, with no cloud computer: everything happens on your Mac
• Sees your screen, so you never explain the setup
• Reads email, files expenses and watches pages, asking before it submits anything
• Remembers your plans, deadlines and people, and brings them up when they matter

Watch out for

• Mac only, and it needs a ChatGPT or Claude subscription you already pay for
• An agent that reads your screen and inbox needs real trust to set up
• A new launch, so long-term reliability is still being proven

Best for

Mac users who already pay for ChatGPT or Claude and want an agent that acts on their screen. Who should skip it: anyone on Windows, or someone with no ChatGPT or Claude subscription.

Pricing

Free to download. Runs on the ChatGPT or Claude subscription you already have.

FAQs

What is Nico? A voice-to-action personal agent for Mac: she lives on your screen, hears what you ask, sees what you see, and gets things done on your device.

Is Nico free? Yes, free to download. It runs on the ChatGPT or Claude subscription you already have, so there is no separate Nico subscription.

What can I ask her to do? Explain a bill from a PDF, tidy your Desktop, turn a table into a spreadsheet, draft an email reply, file an expense, find a restaurant, or watch a page for changes.

Does she send emails by herself? No. A reply goes out only after you have seen it, and she asks before submitting anything like an expense.
