What you need
To use a teleprompter on iPhone you need just two things: your iPhone and the Voice Sync AI app, which is free on the App Store. No extra hardware required. If you want a multi-device setup — a second screen or a remote controller — you'll need a second phone or iPad on the same Wi-Fi network.
Voice Sync AI works on any iPhone running a recent version of iOS. The voice sync feature uses on-device speech recognition, so it works offline too.

Step 1 — Add your script
Open Voice Sync AI and create a new script or import one. The app supports PDF, DOCX, and TXT files, so if your script lives in Google Docs or Word, export it and import directly — no reformatting needed. You can also type or paste your script straight into the app.
Keep your scripts organised by folder inside the app. If you record regularly, having a clean library saves real time between sessions.
Step 2 — Choose your recording mode
Voice Sync AI has two main modes for solo recording:
- Host mode — your iPhone records video and runs the teleprompter at the same time. The script overlays the live camera feed so you can see it while you record. This is the standard solo setup.
- Floating window mode — the script floats as a transparent overlay over any other app. Use this if you prefer recording in a different camera app or streaming tool and just want the prompt visible on top.
For most creators, host mode is the right choice — everything is in one place and you don't need to juggle apps.
Step 3 — Turn on voice sync
This is the feature that separates a modern AI teleprompter from traditional apps. With voice sync on, your iPhone listens to your speech using on-device recognition and highlights the exact word you're saying in real time. As you speak, the script advances word by word — no fixed speed to chase, no tapping to scroll.
To enable it, tap the microphone icon before you start recording. You'll see the script switch into voice sync mode — a listening indicator appears and the first word highlights, ready to follow your speech.
A few tips for getting the best results from voice sync:
- Speak clearly at a natural pace — the engine handles pauses and speed changes without any input from you
- If you riff or improvise a line, just keep going — the script will resync when you return to the text
- Quiet environments give cleaner recognition, but it performs well in typical indoor setups
- Download the offline language pack for your language in settings so voice sync works without internet
Step 4 — Pick your camera and lens
Voice Sync AI gives you full camera control without leaving the app. Switch between front and rear cameras, and choose from ultra-wide, wide, or telephoto lenses where your iPhone supports them. Record at up to 4K and adjust focus, exposure, and white balance manually if you need consistent results across multiple takes.
For talking-head videos and YouTube content, the wide rear camera at 1080p is the most common setup. If you're closer to the camera and want a tighter frame, telephoto gives you a flatter, more cinematic look without physically moving back.
Step 5 — Record
Hit record. The script scrolls with your voice. You can pause and resume at any point — the teleprompter holds your position. When you're done, your video saves directly to your camera roll.
Watch the first take back before doing a second. Most people are surprised how much better they look on camera once the script is keeping pace with their natural delivery rather than a fixed timer.
How to use mirror mode for a teleprompter rig
If you have a physical teleprompter rig — a beam-splitter glass setup that sits in front of your lens — you'll need mirror mode. This flips the script horizontally so it reads correctly through the glass while your lens shoots through it unobstructed.
In Voice Sync AI, toggle mirror mode from the display settings before starting your session. All recording controls remain fully accessible in mirror mode. You can also run mirror mode on a second device in prompt display role if you want to keep the host phone off the rig — more on that below.
How to connect a second device — iPhone, iPad, or Android
Running a teleprompter on iPhone with a second screen is a significant upgrade for anyone who records regularly. Instead of the script overlaying your camera feed, a second device shows it full-screen — easier to read, better eye line, and it frees your host phone to focus entirely on recording.
Here's the setup with two devices:
- Make sure both devices are on the same Wi-Fi network
- On your iPhone, start a session as Host
- On the second device — iPhone, iPad, or Android — open Voice Sync AI and join the session as Prompt display
- The second screen now mirrors the script position in real time, following your voice sync on the host
You can also add a third device as a Remote controller — useful if someone else is on set and needs to control record, pause, and script navigation without touching your camera phone.
Cross-platform sessions — an iPhone hosting while an Android device joins, or vice versa — are available with Voice Sync AI Pro.
Tips for better teleprompter videos on iPhone
- Position the phone at eye level. Looking slightly up or down at the camera reads unnatural. A simple phone stand or tripod makes a big difference.
- Keep the script concise. Teleprompter delivery works best when the writing is punchy and conversational — the same sentence that reads well on paper can sound stiff when spoken. Write the way you talk.
- Do a practice read before recording. Running through the script once without the camera rolling lets voice sync calibrate to your pace and helps you spot any phrases that feel awkward.
- Use natural light or a ring light facing you. Good lighting matters more than a perfect script on camera.
- Pause intentionally. Voice sync holds its position when you pause, so don't rush to fill silence. A deliberate pause before a key point looks confident, not hesitant.
Frequently asked questions
Does iPhone teleprompter work without internet?
Yes. Voice Sync AI runs speech recognition on-device for supported languages. Download the offline language pack in Settings and voice sync works without any internet connection.
Can I use Voice Sync AI with a separate camera app?
Yes, via floating window mode. The script appears as a transparent overlay over any other app on screen, so you can record in your preferred camera app and still read the prompt.
Can an Android phone join my iPhone session?
Yes, with Pro. An Android device can join as a prompt display or remote controller in a session hosted on iPhone, and vice versa. Both devices just need to be on the same Wi-Fi.
What's the best iPhone for teleprompter use?
Any recent iPhone works well. The main advantage of newer models is better camera quality and lens selection — ultra-wide and telephoto are only available on Pro models. For the teleprompter itself, the performance difference between iPhone models is minimal.
