Teleprompter for Webinars and Live Streams: Script the Parts That Should Be Scripted, Wing the Rest

Nobody wants to watch a webinar that is read aloud. Everybody has sat through one that opened with ninety seconds of "um, so, welcome, can everyone see my screen", lost its thread at the handover to the demo, and ended with "so yeah, that's it, I guess, thanks". The fix for both problems is the same: script the small number of moments that are the same every time, and leave the rest alone. This post is about doing that with an iPhone teleprompter, for webinars you present from a laptop and for live streams where the camera is the phone itself.

The three minutes worth scripting

In a typical forty-five minute webinar, roughly three minutes are identical every time you run it, and those three minutes carry a disproportionate share of the impression you leave. They are:

• The open (60 to 90 seconds). Who you are, what the session covers, what the viewer will be able to do afterwards, and the housekeeping: recording, questions, slides. This is where people decide whether to stay. It should be tight, confident and the same every time.
• The transitions (15 to 30 seconds each). The handover from slides to demo, from demo to case study, from content to Q&A. These are where presenters ramble, because the brain is busy with the screen share rather than the words.
• The close (45 to 60 seconds). The summary of the three things you want remembered, the one action you want taken, and where to find the recording and the follow-up. The close is the part most people improvise, and it is the part that decides whether anyone clicks the link.

Everything in between, the explanation, the demo, the answers, should not be on a prompter. You know the material, and the audience can tell the difference between someone explaining and someone reading. Write the open, the transitions and the close as separate short scripts, and treat the rest as notes.

Setup A: webinar from a laptop, phone as prompter

Most webinars are presented from a laptop with its built-in camera, through Zoom, Teams, StreamYard, Riverside or whatever the platform demands. The phone is not the camera here; it is the prompter. The way to use Teleprompter: Camera Overlay in this setup is to prop the phone directly beneath the laptop's webcam (or just below the external webcam on top of the monitor) and run the script with voice-follow scrolling on. You do not press record, because the laptop is doing the recording or the streaming. The script floats over the phone's own camera preview, and because the phone sits right under the lens you are looking at, your eyes stay within a few degrees of the webcam.

Voice-follow matters more here than in a recording. In a webinar you will stop to answer a question, go off script for a sentence, then come back. Classic auto-scroll keeps rolling while you are talking to the chat and you return to find the text three paragraphs ahead. Voice-follow listens for where you are and advances only when you say the words, so when you come back to the open or the close, the script is still waiting at the line you left. The voice-follow vs auto-scroll comparison goes through when each is the right choice; for anything live, it is voice-follow.

Two practical details. Turn the text size up: the phone is further from your eyes than it would be if you were filming on it, and the script should be readable without squinting. And mute the laptop microphone's view of the phone: the app's speech recognition runs on the phone, listening to you, and it does not need to be anywhere near the laptop's mic. Nothing is uploaded, because the recognition is Apple's on-device speech recognition, so it works just as well on a venue Wi-Fi that is being hammered by two hundred attendees.

Setup B: live stream where the phone is the camera

For an Instagram Live, a TikTok Live or a YouTube live stream from the phone, the situation is different, and it is worth being honest about it. iOS gives one app the camera at a time. If you are streaming from the Instagram app, Instagram owns the camera, and no other app can draw a script over its preview. A camera-overlay teleprompter cannot overlay a script on a live stream run by a different app; that is a platform limitation, not something an app can work around.

What you can do is use a second device. The phone that streams sits on the tripod; a second iPhone with the teleprompter runs the script beneath the lens, and you treat it exactly as in Setup A. If you only have one iPhone, the practical approach is to pre-record the scripted segments (the intro you play at the top, the sponsor read, the outro) using the app's own 4K recording, and go live unscripted for the conversation. Several streamers do exactly this: a polished recorded open, then the live part, then a recorded close.

If you are streaming through a desktop tool such as OBS with the phone as a camera source, the same rule applies: the phone's camera is being used by the capture app, so the script needs to be on a different screen. A laptop below the lens with the script in a text editor works, or a second iPhone with the app.

Writing webinar scripts that survive contact with an audience

A webinar script is a different animal from a 60-second video script. The audience is live, the chat is scrolling, and your attention is split. Three adjustments help.

• Write in short lines with deliberate full stops. Long sentences are fine when you can retake. Live, you need places to breathe, glance at the chat and come back. One idea per line.
• Put the housekeeping in square brackets, not prose. "[Check: recording on. Questions in the Q&A panel.]" reads as a checklist, and you will say it in your own words rather than reciting a paragraph.
• Script the question-handling phrases. "Good question, I'll come back to that in the Q&A" and "Let me finish this section and then take that" are worth having on the prompter, because the moment you need them is the moment you are least able to think of them.

Keep each script short enough to be a single screen or two in the app. The unlimited scripts library is there precisely so you can keep an "open", a "demo handover", a "Q&A transition" and a "close" as separate entries, and switch between them with a tap while the audience watches a slide.

The rehearsal that actually matters

Record the open and the close once, in the app, as if they were standalone videos. Watch them back. The point is not to produce a video; it is that a recording is the fastest way to hear whether a script sounds like you. If the open sounds like a press release, cut it by a third, which usually means deleting the sentence that explains why the topic is important. The audience signed up; they know. The post on the most common teleprompter mistakes covers the reading-voice problem in detail; the short version is that the fix is almost always a shorter script, not a better reader.

Then run the whole session once with the prompter in position but without reading from it. You will discover whether the phone is in your eyeline or whether you have to look down, whether the text size is right, and whether voice-follow picks you back up after you talk to the chat for a minute. Fix those in rehearsal, not at 10:02 with eighty people watching.

When not to bother

A small internal session, a working meeting, a weekly stand-up on camera: a prompter adds friction and takes away the conversational tone that makes those work. If the session is genuinely a conversation, a sticky note with three bullet points beats any script. The teleprompter is for the moments that are a performance, and the honest test is whether you would be embarrassed by a recording of how you currently open and close. If the answer is no, you do not need this post.

The other case is a webinar you are running for the twentieth time. By then the open is in your bones, and the prompter is a safety net you no longer look at. That is fine; leave it running under the webcam anyway. The day the Wi-Fi drops mid-sentence and you have to restart, it will be the thing that lets you pick up without a stumble.

What this costs

Teleprompter: Camera Overlay is free with occasional ads and a small one-time purchase to remove them; there is no subscription and no watermark on recordings. It runs entirely on the iPhone, works in airplane mode, and never uploads your script or your takes. It is iOS-only, so the second device in Setup B needs to be an iPhone.

Webinar scripts are short by design. The next post in this series deals with the opposite problem: reading long scripts, the ten-minute explainer or the full keynote, without losing your place when the words run to several screens.
