What is a teleprompter? A plain explainer of how they work and who uses them

A teleprompter is a device that displays a scrolling script near the camera lens so a presenter can read their words while appearing to look straight at the audience. It lets you deliver a full script with steady eye contact, without memorizing it or glancing down at notes.

That's the short answer. But "teleprompter" covers everything from broadcast studio rigs to a free browser tab on your phone, and they don't all work the same way. This explainer walks through how teleprompters work, the main types, who uses them, and how modern app-based prompters have changed the picture.

How a teleprompter works

Every teleprompter does the same basic job: it puts your script where your eyes naturally fall when you're looking at (or very near) the camera, and it moves the text along at reading speed so you never lose your place.

The classic studio version does this with optics. A piece of angled beamsplitter glass — partly reflective, partly transparent — sits in front of the lens. A screen below reflects the script up onto the glass, so the words appear to float right over the lens. The camera shoots straight through the glass and never sees the text. Because the glass reverses the image like any mirror, the script is flipped on the screen so it reads correctly in the reflection.

Simpler setups skip the glass. A phone or tablet sits right beside the lens with the script scrolling, and you read from there. Your eyeline is slightly off-axis, but close enough that it reads as natural eye contact to most viewers. Either way, the core idea is the same: keep the words near the lens and move them at the pace you talk.

The main types of teleprompter

Hardware beamsplitter rigs

These are the camera-mounted units with angled glass and a hood. They range from heavy studio rigs to compact phone-and-tablet mounts you can put on a tripod. They're the gold standard for on-axis eye contact because the text sits directly over the lens. The trade-off is cost, setup time, and gear to carry. If you want the full breakdown, see our guide to the teleprompter mirror.

Presidential prompters

You've seen these at speeches and keynotes: two glass panels on thin poles, angled on either side of a podium. They're beamsplitter prompters too, but the speaker reads them directly rather than through a camera. Placing one on each side lets the presenter sweep their gaze naturally across the audience while always having the script in view. The name comes from their long use in political addresses.

Software and app teleprompters

This is a prompter that runs as software on a device you already own. There's no special hardware required — you load your script, and it scrolls fullscreen on your screen. DocPrompter is this kind: it runs in the browser, so there's nothing to install, and works on a laptop, phone, or tablet. You paste a Google Docs link or raw text and it becomes a fullscreen scrolling prompter. If you also have a beamsplitter rig, app prompters with a flip mode drive the screen under the glass — so the software and hardware categories often work together.

Phone teleprompters

A phone teleprompter is just an app prompter running on your phone, often propped beside the lens or slotted into a small beamsplitter mount. It's the most accessible option — the screen is already in your pocket — and it's how most solo creators, especially on social video, run a prompter. Here's a walkthrough of using a teleprompter on your phone.

Who uses teleprompters, and why

Teleprompters started in broadcast, but the audience is much wider now. News anchors and TV hosts use them to deliver long scripts live without fumbling. Politicians and executives use presidential prompters for speeches. YouTubers, course creators, marketers, and anyone recording talking-head video use app and phone prompters to get clean takes.

The reasons come down to three things:

• Eye contact. Reading near the lens keeps you connected to the viewer instead of staring down at a script.
• Fewer retakes. When you're not fishing for the next line from memory, you stumble less and finish in fewer takes.
• No memorizing. You can deliver a precise, fact-checked, or legally-reviewed script word for word without rote learning it.

How modern app prompters work

Older prompters scroll at a fixed speed you set in advance, which means you're always adjusting to the machine. Modern app prompters flip that around with a few scroll modes:

• Manual — you control the scroll yourself, full stop.
• Fixed-time — the text scrolls at a steady speed you set, the classic approach.
• Voice-follow — the prompter listens as you speak and moves the text to match, pausing when you pause.

Voice-follow is the one that changes how it feels to use a prompter. Because the text follows your voice, you can slow down for emphasis, pause to think, or ad-lib a line, and the script waits for you instead of marching ahead. In DocPrompter it works in Chrome and Edge, and on iOS Safari 16.4 and up, and it's available on the free plan. It pairs well with our advice on recording without memorizing — you keep the script as a safety net but speak like a person.

App prompters also add conveniences hardware can't: themes and rotation, an eye-line marker, screen wake-lock so the display stays on, adjustable font, width, and line height, and a send-to-device QR code so you can push your script to a phone or tablet that doesn't even need a login. For scripts that change often, live Google Docs sync keeps the prompter matched to your latest edits.
