Give your agent
eyes and ears.
Record your screen, dictate what you want, and Zerro turns it into exactly what you need: an agent prompt, a message, a snippet, a written-up document, or even real-time updates to your website or application.

What is Zerro?
Show your screen. Say what you want.
Screenshots can show the AI your screen, but they can't point out what you're focused on or spell out what you want changed. That part is on you to type out, and it's the slow, frustrating step. Zerro lets you record what's actually happening and just say what you want, then turns it into exactly what you need.
Use it for
- Hand a coding agent real context
- Draft a message about what's on screen
- Grab the exact formula or snippet you need
- Turn messy notes into a clean write-up
- Get a confusing screen, error, or chart explained
- Make changes to your website in real time using Dev Mode
How it works
Record. Speak. Copy.
Speak what you need and get a ready-to-use artifact or answer from the menu bar.
Select a region
Hit the hotkey, drag to frame the part of your screen you want Zerro to see. Native macOS crosshair, no window switching.
Dictate what you want
Talk it through like you'd explain it to a teammate. Point at things, change your mind, ramble. Zerro records up to 3 minutes.
Prepped on your Mac, then AI
Your Mac prepares the recording and masks on-screen secrets first. Then one AI call creates the result: Managed in the cloud, or BYOK with your own key.
Paste it anywhere
It lands on your clipboard (agent prompt, message, snippet, or document), ready to drop into Cursor, your inbox, a sheet, or wherever it's headed.
The difference
Stop Typing It. Just Say It
Record your screen, say what you want, and Zerro turns it into exactly what you need. No typing a description by hand.
The way you do it now
- Screenshot a few parts of your screen
- Paste them into your coding agent
- Type out, in detail, what you want
Writing that description out is the slow, tedious part.
With Zerro
- Hotkey, then record your screen
- Talk through what you want, out loud
- Paste the finished result wherever it goes
Say it instead of typing it. Same context, a fraction of the effort.
The output
It Writes Itself.
Every recording becomes exactly what you need: an agent prompt, a message, a snippet, or a document, written up and ready to use. Or, when you just want to understand something, a clear answer in plain language.
One recording. The right artifact.
Instructs your AI agent to fix the silent failure on the checkout promo-code field and surface a clear validation error.
Fix the promo-code validation on the checkout Order Summary.
- 1. Locate the "Apply" button beside the promo-code field (current value: SAVE20) in the Order Summary panel.
- 2. When an applied code is invalid or expired, the field currently does nothing: no error, no spinner, no state change.
- 3. On an invalid code, render an inline error directly beneath the field in red (e.g. "This code is expired or invalid").
- 4. Keep the existing layout and totals; this is a validation fix, not a redesign.
Example output. Every prompt is generated from your real recording.
Dev Mode
Describe the changes,
watch them happen.
Build and iterate with a single shortcut and your voice.
Record your screen and say what you want changed. Zerro turns it into a clear, step-by-step plan, then hands it to your coding agent, which makes the edits and updates your site as you watch.
No more screenshots to explain what you mean. Just describe the change out loud and your coding agent takes it from there.
Works with your CLI agent
Bring your own agent. Zerro auto-detects the CLIs installed on your Mac and runs the one you pick, locally.
Built right
Native, local-first, no surprises.
Zerro is built the way you'd build it if it were your tool.
Native Swift & SwiftUI
A real menu-bar app, built on ScreenCaptureKit. Not an Electron tab pretending to be a Mac app.
Local-first processing
Your Mac prepares the recording and redacts sensitive info before anything leaves. Managed sends it to an AI provider; BYOK sends it straight with your key. No Zerro servers.
Bring your own key
On BYOK, your OpenAI, Gemini & Anthropic keys are stored in macOS Keychain and recordings go straight to your provider on your own key, never through Zerro's servers.
Cost-bounded by design
A 3-minute hard cap on every recording keeps each request fast, cheap, and predictable.
Signed & notarized
Distributed direct as a code-signed .dmg. macOS Gatekeeper will not complain.
Sparkle auto-updates
Updates ship through Sparkle, the standard for indie Mac apps. You stay current without thinking about it.
The shift
Now we're talking.
The keyboard was never the point; it was just the only interface we had. As agents get better at acting on what you actually mean, typing out every instruction by hand starts to feel like the bottleneck it always was.
You think faster than you type. You talk faster than you think. Voice closes that gap, and dictation is becoming the default. Zerro is built for that future: less typing, more talking.
Words per minute
You speak nearly 4× faster than you type. The keyboard has been the bottleneck all along.
