Field notes

Your calls and your decks: what Tellie does where.

Two questions arrive constantly, and they have opposite answers. Does Tellie work with Teams, or Webex, or Meet? Yes, always, and the app you use genuinely does not matter. Does Tellie work with PowerPoint the way it works with Keynote? No, and it is worth being exact about why.

The call app never matters

People assume Tellie must integrate with Zoom, because that is how these things usually work. It does not, and that is the good news.

The prompter window is marked as excluded from screen capture by macOS itself. Not by Zoom, not by a plugin, not by a setting you have to remember. The operating system simply does not hand that window to anything asking for your screen. So the question "does it work with X" has the same answer for every X: your audience sees your face and your slides, and never the words you are reading.

One row would have done. The point is that there is no list to maintain, because the hiding happens a layer below all of these.

It also does not want your microphone to itself

The other half of "the call app never matters" is that Tellie does not fight your call for the two things it needs. Zoom can hold the microphone and Tellie still hears you: macOS lets more than one app read an input device at once, and Tellie never asks for exclusive access. Your meeting audio is untouched.

And Tellie does not need to be the app you are using. It has no Dock icon and never takes focus, so your call stays frontmost, your keyboard still belongs to it, and the script keeps following your voice in the background. You are not alt-tabbing to a teleprompter in the middle of a sentence. You are just talking.

That is a consequence of a decision made early rather than a lucky accident. Tellie captures audio through a path chosen specifically so it keeps working for an app that lives in the menu bar instead of the foreground.

The deck app does matter

Here the honest answer is narrower, so here is the line drawn plainly.

Presenter Magic reads your speaker notes out of Keynote and puts the current slide's notes in the notch, changing as you advance. It works with Keynote and with the newer Keynote Creator Studio, because Tellie talks to both. Your notes were already written; they simply appear where your eyes already are.

PowerPoint and Google Slides do not do this. Tellie cannot read their notes, so nothing arrives in the notch automatically and nothing advances with your slides. This is a real gap and not a configuration you have missed.

Google Slides runs in a browser, which puts its notes out of reach entirely. PowerPoint is a native Mac app, so it is a question of work we have not done yet rather than a wall.

So what do you do if your company runs on PowerPoint?

Something less clever that works today: paste your notes into Tellie and read them as one script, while PowerPoint does the slides. You lose the automatic sync. You keep the part that matters most, which is that you are looking at the camera instead of down at a second screen, and nobody can tell.

Two things make that better than it sounds. Voice Follow scrolls the script by listening to the words you actually say, so you are not hunting for your place after an interruption or a question. And a couple of quiet marks turn a flat script into one that tracks you: write ## ! on a section you must not skip and Tellie makes sure you reach it, greens the text as you cover it, and warns you if you are going to run out of time before you get there. The scripting guide is two minutes long and includes a ready-made script to start from.
