Tellie's Story: Making an App in the Age of AI

As answered by people managing JavaScript Tutorial and Tellie Prompter.
Tellie Prompter's answer:
Anyone who has to look into a camera on a Mac and sound like themselves. Executives on back-to-back video calls, educators recording lessons, podcasters and creators shooting solo, salespeople who want to land every point without sounding like they're reading. If you talk to a lens for a living, Tellie was built for you.
Tellie Prompter's answer:
Tellie Prompter's answer:
Tellie is a native Mac app, Apple Silicon only, and all of its listening happens on your Mac using Apple's on-device Speech framework - no audio leaves the machine, no account, no telemetry. The part I'm proudest of is our own word-level matcher, which aligns what you actually said to your script in real time, across more than 40 languages. And yes, I built it with AI assistance - a three-day prototype that's grown into the polished app shipping today.
Tellie Prompter's answer:
I'm not a coder. I woke up at 3am with the idea and, with AI as my pair programmer, built the first version in three days - much of it while my granddaughter Ellie, who the app is named after, napped. The better story is the second idea: once Tellie could follow my words, I realized it could also track what I still needed to say, and that became Stagehand, the feature nobody else has. I keep a drawer full of ideas I never got around to building. Tellie is the one that got out.
Tellie Prompter's answer:
Because it understands, it disappears, and it's honest about what it costs. Tellie matches your speech to your script word by word and shrugs off paraphrases and improvised detours - other prompters just keep scrolling without you. It lives in your Mac's notch, invisible to Zoom and Meet screen share, so your audience sees you, not a prompter. And it's free to use for real, with Pro at $29 once - not a subscription, not a crippled demo.
Tellie Prompter's answer:
Every other teleprompter scrolls. Tellie listens. It follows your actual words as you speak - pause, skip ahead, ad-lib, wander off script and come back - and it keeps up. It also tracks the points you still owe your audience, not just your position in the script, so the thing you meant to say actually gets said. That's why we call it the Mac teleprompter that understands.
