Zolt saying hi, listening, thinking, talking, having an idea, taking meeting notes and napping

What Zolt can do

🎙️ Talk to it

Click Zolt or press ⌃⌥Space, say what you need, and it answers in a speech bubble that scrolls along as it talks.

📼 80s robot voice

Replies read aloud in classic Mac voices: Zarvox, Trinoids, Fred, Ralph. Or switch the voice off.

🛠️ Does things on your Mac

"Remind me to call Mom at 6", "set volume to 30%", "open Spotify". Every action asks Allow or Deny first.

👀 Looks at your screen

"Look at my LinkedIn. What would you improve?" One screenshot, only when you ask.

📝 Meeting notes

Notices Teams, Zoom or Google Meet calls and asks before taking notes. You get a live transcript, then a TL;DR, decisions and action items.

💡 Suggested answers

Optional: when someone asks you a question on a call, a suggested answer quietly appears in your notes window.

Meet Zamil 🇸🇦

Zamil, Zolt's Arabic-speaking sibling, in a shemagh and agal

Zamil (زميل) means companion in Arabic. It's Zolt's sibling: it wears a red-and-white shemagh, understands spoken Arabic and replies in Arabic.

It runs side by side with Zolt, with its own hotkey (⌃⌥Z). Download Zamil.zip from the same release.

Install in 3 steps

  1. Give it a brain. Install Claude Code, then run claude once to sign in. You'll need a paid Claude account, as the free plan doesn't include Claude Code: 
    curl -fsSL https://claude.ai/install.sh | bash
  2. Download Zolt (or Zamil) from the latest release, unzip it, and drag it into Applications.
  3. First launch: macOS blocks unsigned apps once. Open System Settings → Privacy & Security → Open Anyway. Then click Zolt and say hi.

Prefer to build it yourself? git clone https://github.com/c0ldskin/zolt-bot.git && cd zolt-bot && ./build.sh --run
