Stop copying and pasting between tools. Just talk — and your text shows up exactly where you need it.
If you use AI daily, this will save you hours.
Windows 10+ • No account required • No setup headaches
Windows will show a security prompt on install — code signing is in progress. We ship fixes fast.
The problem
Marcos removes all of that. You just talk — and it's already there.
How it works
One installer. Runs in under a minute. Marcos appears in your system tray, ready to go.
A small animated mascot pops up on your screen. It's listening. Start talking naturally.
Whatever app has focus gets the text. ChatGPT, VS Code, Slack, your browser — anywhere.
What you get
Your words appear as you speak them — not after a pause. Feels like actual typing.
No plugins, no integrations. Text lands wherever your cursor is — any app, any window.
No internet? No problem. Marcos can run a local model entirely on your machine. Your audio never leaves your device.
Auto-hides when you're not using it. Appears when you need it. Lives quietly in your tray.
Nothing stored on our end. What you say is yours. Choose offline mode for complete privacy.
Text is typed directly as keystrokes. Your clipboard is never touched.
Who it's for
You're writing to ChatGPT, Cursor, or Claude dozens of times a day. Speaking is faster and your hands stay on the keyboard where they belong.
You think faster than you type. Marcos keeps up. Speak a paragraph, edit later — your hands are never the bottleneck again.
Slack, email, Notion, Jira, browser tabs. If you're moving text between apps all day, Marcos eliminates the friction entirely.
Every other voice tool sends your audio to a server. Deepgram, Whisper API, Google — all cloud-dependent. Marcos is the first dictation tool that runs a full speech model entirely on your machine. Your words never leave your device. Not even for a millisecond.
Powered by Whisper running locally. <300ms latency. No subscription required.
Your crew
Marcos is the default, but you can switch to Gerald, Fluffy, Leon, Panda, or the Owl. All animated. All audio-reactive.

FAQ
Is Marcos really free?
Yes — for early access users. The first 50 people get full access to the current Windows version at no cost, locked in before we ever start charging.
Why does Windows show a security warning?
Windows SmartScreen flags installers that aren't code-signed yet. We're in the process of getting a code signing certificate. You can safely click “More info → Run anyway.” The app is safe — we're just early. We ship fixes fast.
Does it work without internet?
Yes. Marcos has a built-in offline mode powered by Whisper running locally on your machine. Your audio never leaves your device — not even for a millisecond.
Which apps does it work in?
Any app with a text input — ChatGPT, Claude, Cursor, VS Code, Slack, Notion, Jira, your browser, email clients, anything. Marcos types directly as keystrokes, so if you can type somewhere, Marcos can speak there.
Why is Premium priced at $80/month?
Because this is a genuinely new kind of product. We're not just adding a microphone button — we're building a voice-native layer that sits across your entire computer, phone, and eventually every interface you use. iOS, Android, agent skills, real-time cross-app actions — this is infrastructure, not a widget. The $80 tier exists for early adopters who want to be part of something that could fundamentally change how people interact with computers and AI. More features are coming fast, and this price reflects the vision, not just what's already here. Rheo Research's goal is to advance how humans interact with technology across every platform — and Premium users are backing that directly.
What is Rheo Research?
Rheo Research is the company building Marcos. Our focus is advancing human-computer interaction — making interfaces more fluid, more intelligent, and more natural across desktop, mobile, and beyond. Marcos is the first product that embodies that mission. Learn more at rheoresearch.org.

This is an early version. Windows may show a security warning on install because the app isn't code-signed yet. Totally fair if that's a concern — I'm working on it.
This is being shaped directly by early users. If you try it, I'd genuinely love your feedback — what works, what doesn't, and what one annoying step in your AI workflow you'd most want to eliminate.
