YOUR PERSONAL AI, LIVE ON YOUR MAC

An AI that knows your calendar, reads your emails, browses the web, controls your browser, and remembers everything. All while you talk to it naturally.

🎙️

Voice-first

Talk to Nix like a person. It listens via local Whisper, understands context, and replies in a natural voice via Deepgram.

🧠

Has memory

Nix remembers past conversations, ongoing projects, and your preferences across every session.

⚡

Takes action

It doesn't just answer questions. It edits files, controls browsers, manages calendars, and ships work.

WHAT NIX DOES

One assistant. Every context.

Nix plugs into the tools you already use and handles the busywork so you can focus on what matters.

📅

Calendar & scheduling

Checks your day, moves events, flags conflicts, and tells you what's coming. Just by asking.

📬

Email intelligence

Scans your inbox for what's important, drafts replies, and surfaces threads you shouldn't miss.

🌐

Live web research

Searches the web, opens pages, reads articles, and summarizes findings while you watch.

💻

Browser control

Navigates real browser tabs, fills forms, clicks buttons, and takes screenshots to show you what it sees.

📂

File & code editing

Reads, edits, and creates files on your machine. Like this page, which Nix built and is editing live.

🔔

Proactive alerts

Scans your email and calendar every 2 hours and your GitHub activity hourly, and tells you if something needs your attention, without being asked.

HOW IT WORKS

Talk. Nix acts. You see it happen.

No forms, no dashboards, no configuration. Just say what you need. Nix figures out the steps and shows its work in real time.

1️⃣

You speak or type

"What's on my calendar tomorrow?" or "Find Jason Koo's latest blog post and prep my podcast notes."

2️⃣

Nix reasons & acts

It picks the right tools, searches, reads, edits, or calls APIs, narrating what it's doing at each step.

3️⃣

You get results

A spoken summary, a file, a browser open to the right page, or a calendar event. Already done.

BUILT WITH

Nix is built on best-in-class cloud APIs, running on your Mac, with your data, on your terms.

🤖

Claude (Anthropic)

The brain. Claude Sonnet powers Nix's reasoning, tool use, memory synthesis, and natural conversation.

🎤

Local Whisper STT

A warm whisper.cpp server running on-device for fast, private speech-to-text with no cold start.

🗣️

Deepgram TTS

Aura voice model streams in real time, so replies feel instant and natural.
