Tellie
Follows your voice. Word by word. Private. Gives every Mac a notch. Free to download.
If you've ever tried to record a video or present on Zoom while reading notes, you know the problem: your eyes dart off-screen and you look like you're reading. Every teleprompter I tried either scrolled at a fixed speed or showed up when I shared my screen.
So I built Tellie. Here's the part that matters, because it's what most of these apps get wrong: they speed the scroll up and down when they hear you talk. Tellie tracks the actual words you're saying and highlights exactly where you are, so you can skip a line, go back, or improvise and it stays with you. Word-level tracking, not pace-matching. About 50 languages, all on-device using Apple's Speech framework. Nothing ever leaves your Mac.
Lives in the MacBook notch (right under the camera) or detach and float anywhere. Invisible to Zoom, Google Meet, screen recorders, and screenshots. Opt-in recordable mode for demos.
Working actors found it on their own, which still surprises me. Sprague Theobald (Law & Order, Only Murders in the Building, FBI, Poker Face) uses it for audition prep, and since he's dyslexic, the built-in OpenDyslexic font helps him read scripts more comfortably.
NEW: Presenter Mode (Pro). Load your Keynote speaker notes into Tellie. Notes appear in the notch while you present, invisible to your audience. Voice Follow auto-advances your slides when you finish your last word. No clicker, no keyboard, no glancing away.
Free version is a full teleprompter. Pro adds voice-follow, Presenter Mode, pace reports, playlists, one-key retake, section nav, global hotkeys. One-time purchase, no subscription. 14-day refund.

I'm an ex-Apple exec (Steve Jobs personally rehired me in '97) who's never written production code. I designed Tellie to feel like it belongs on a Mac: quiet, fast, considered. Built in 3 days using AI as my coding partner.
