Tellie lives right inside the MacBook notch. It holds the exact thing you need while you focus on the camera, the room, and your audience. It started as a simple teleprompter that follows your voice, and that is still why working actors and creators love it. But then it became something more. That same tiny screen now follows your slides, your clicks, and even your AI agents. It stays completely invisible to Zoom and screen recorders, with everything processed securely on your Mac. I spent my early career helping Steve Jobs save Apple, but I built this entire app in three days without writing a single line of code. I named it after my granddaughter, Ellie. She is just learning to read. Now you never have to look down again.

Tellie is your silent second screen for Mac, built around the MacBook notch. It started as a teleprompter that listens: on-device speech recognition matches the words you say to the words on screen and scrolls to keep up, in about 50 languages. The same screen does more. In Presenter Mode it shows your Keynote speaker notes and advances slides when you finish a thought. For developers, any app, script, or AI agent can push a line to the notch. Tellie stays invisible to Zoom and screen recorders, and everything runs on-device. No account, no telemetry. Free to download. macOS 14 or later. tellieapp.com

Tellie is your silent second screen for Mac. It lives in the space around the MacBook notch and holds what you need while you look at the camera, the room, or your audience. It began as a teleprompter that listens, using Apple's on-device Speech framework to match the words you actually say to the words on your script and scroll to keep up, in about 50 languages, with no audio ever leaving your Mac. Speed up, slow down, ad-lib, or skip a line; the script follows you. That teleprompter is still what working actors and creators reach for, but it turned out to be one shape of a bigger idea. In Presenter Mode, Tellie shows your Keynote speaker notes in the notch and advances your slides when you finish a thought, so the next slide is already there before you reach for the clicker. For developers, any app, terminal, or AI agent can push a line to the notch through the tellie:// scheme or the @tellie/mcp and @tellie/cli packages on npm, so a build result, a test outcome, or an agent's question appears the instant it matters. Tellie stays invisible to Zoom, screen recorders, and screen sharing, so whatever it holds stays yours, and everything runs on-device with no account and no telemetry. It opens text, Markdown, RTF, Word, and PDF, ships serif, sans-serif, and OpenDyslexic fonts, and remembers font size, speed, and position per file. The notarized DMG is about 2.4 MB. Tellie was created by Steve Chazin, a former Apple exec rehired personally by Steve Jobs in 1997 and later a leader at Cisco and Salesforce, who built the first version in three days, about 4,000 lines of Swift, entirely by talking to an AI agent, despite never writing production code. He built it during a visit to his granddaughter in Vermont, working while she napped or was at school, and named the app after her. Her name is Ellie, and she is just learning to read. More than 300 people are already using Tellie during a quiet soft launch, including working film and TV actors. Tellie is part of Chazin's "AI for the Rest of Us" project at stevechazin.com. Free to download. macOS 14 or later. Available at tellieapp.com.

Steve Chazin spent more than 30 years leading product and marketing at Apple, Cisco, Salesforce, Alarm.com, and Symantec. At Apple, he was personally rehired by Steve Jobs in 1997 to help return the company to profitability. At Cisco, he helped grow WebEx from $900M to $1.3B in annual recurring revenue and helped create Cisco Spark. At Salesforce, he led the acquisition of Dimdim and designed Chatter Messenger, which predated Slack. He now runs Skytech.io, writes about AI for non-technical readers at stevechazin.com under the banner "AI for the Rest of Us," and hosts the podcast The Skytech Minute. His goal is to be the Bill Nye of AI: translating the technology clearly, without hype or doom, for everyday people. Tellie is his first shipped Mac app. He built it in three days, entirely by talking to an AI agent, during a visit to his granddaughter in Vermont this month, sneaking the work in while she napped or was at school. The app is named after her. Her name is Ellie, and she's just learning how to read. He calls this moment the Digital RenAIssance: when the bottleneck to building software shifts from technical skill to imagination.
Watch
Tellie is invisible to Zoom, screen recorders, and screen sharing. That's how scripts stay private. It also means we can't screen-record Tellie itself, so both videos below were filmed with an iPhone on a tripod pointed at the Mac. Working as designed.
Steve introduces Tellie to camera, then turns an iPhone toward the laptop screen so you can see the prompter scrolling in real time. Voice Follow demoing itself. Best clip if you only watch one.
Deeper tour: Voice Follow in about 50 languages on-device, the privacy story (nothing recorded, nothing uploaded, no account), keyboard shortcuts for font size and speed, and the fixed-scroll fallback for traditional teleprompter use.

The teleprompter that follows your voice was just the first step. Tellie now follows your slides, your clicks, and even your AI agents.
FAIRFAX, VA. Steve Chazin, a former Apple and Cisco product leader, today launched the next chapter of Tellie, a free Mac app that turns the space around the MacBook notch into a silent second screen: always there, holding the one thing you need while your attention is committed elsewhere.
Tellie began as a teleprompter that listens. Its on-device voice follow matches the words you actually say to the words on screen and scrolls to keep up, in about 50 languages, with no audio ever leaving your Mac. For a lot of people, from solo creators to working actors, that teleprompter is still the magic. But it was the first step, not the last.
The same screen now listens in more ways. In Presenter Mode, Tellie shows your Keynote speaker notes in the notch and advances your slides when you finish a thought, so the next slide is already there before you reach for the clicker. For developers, any app, script, or AI agent can push a line to the notch, so a build result, a test outcome, or an agent's question appears the instant it matters. As of this month, that developer surface is published on npm as @tellie/mcp and @tellie/cli.
"The teleprompter is where Tellie started, and people genuinely love it there," said Chazin. "But it was the first step, not the destination. The real idea is a quiet canvas that is always a glance away, holding the thing you need while you look at the camera, the room, or your code. Reading a script is one use. Running a talk is another. Watching your agents is another. We are just getting started."
More than 300 people are already using Tellie during a quiet soft launch, with a growing handful paying for Pro, including working film and TV professionals who found it on their own. "It truly is a magnificent app," said Sprague Theobald, a two-time Emmy Award-winning writer/producer and actor whose credits include Law & Order, Only Murders in the Building, and FBI.
Whatever Tellie holds stays private: it is invisible to Zoom, screen recorders, and screen sharing, and everything runs on-device with no account and no telemetry.
The origin story is now part of Tellie's identity. Chazin spent 30 years in tech but never wrote production code. He built the first version in three days, about 4,000 lines of Swift, entirely by talking to an AI agent, during a visit to his granddaughter in Vermont, working while she was asleep or at school. He named the app after her. Her name is Ellie, and she is just learning to read.
"Code is cheap. Judgment is dear," Chazin said. "I did not type a line of it, and I am proud of every decision: where the window sits, how it disappears, what is free, what it should never do. The eyes were always mine."
Chazin frames Tellie as proof of a larger shift he calls the Digital RenAIssance, where the barrier to building software is no longer technical skill but imagination. "Your idea drawer has been closed long enough," he said. "Time to open it."
Tellie is free to download and runs on macOS 14 or later. The live developer surface is free; persistent and pro surfaces such as Presenter Mode are a one-time Pro upgrade. Available at tellieapp.com.

Kept for reference: the original third-person announcement and a first-person founder's note.
A 30-year tech exec built his first Mac app in three days. Without knowing how to code. Here's what he shipped.
FAIRFAX, VA. Steve Chazin, a product and marketing leader at Apple, Cisco, and Salesforce, today announced Tellie, a Mac teleprompter that listens to your voice and scrolls the script to match.
Built in three days using AI as a pair programmer, Tellie uses on-device speech recognition to match what you're actually saying to the words on screen. The app lives in the MacBook notch, stays invisible to Zoom and screen recorders, and processes all speech locally. Nothing ever leaves your Mac.
Chazin built the app this month during a visit to his granddaughter in Vermont. He worked in the hours when she was napping or at school, then named the app after her. Her name is Ellie. She's three and just learning to read.
"The bottleneck for creating software used to be technical skill," Chazin said. "Now it's imagination. I built Tellie because I needed it for my own work. But shipping it proved something bigger: ordinary people can now build real, useful software without permission from a tech company or years of training."
"It's the first Mac app I've ever made," he added. "And I made it for a kid who's just learning to read."
Tellie is free to download, runs on macOS 14+, and is available at tellieapp.com. The notarized DMG is approximately 2 megabytes.

I spent 30 years helping companies like Apple and Cisco build products, but I never wrote a single line of production code myself. I have always been the person who translates complex technology into simple, human benefits.
This week, everything changed.
I built Tellie for myself in three days by talking to an AI agent. I am visiting my granddaughter in Vermont this month, and I actually built the app while she was asleep or at school. Her name is Ellie. She is just learning to read, and I named the app after her.
Tellie is a Mac teleprompter that actually listens to your voice. Instead of forcing you to match a robotic scrolling speed, it waits for you. It scrolls when you speak. It stops when you pause. It is a simple tool designed to help creators look directly into the camera and connect with their audience.
But Tellie is also proof of something much bigger. We are living in a Digital RenAIssance. The barrier to creating software is no longer technical skill. It is just imagination. You do not need a computer science degree to build something beautiful and useful anymore. You just need an idea and the willingness to try.
I hope you love using Tellie as much as I loved building it.
