SottoCompare / PromptSmart
Sotto vs PromptSmart Word tracking on a subscription, or one payment and a prompter under your camera.
PromptSmart Pro is one of the best-known teleprompter apps, and its VoiceTrack follows the words you say. Sotto does less, on purpose. It keeps your script right under your Mac's camera or your iPhone's front camera, scrolls while you talk, and costs one payment.
We make Sotto, so we're not neutral. Every fact about PromptSmart here comes from its website or App Store listing, checked on 12 November 2026 (sources). Sotto launches soon on the Mac App Store and the App Store.

Feature by feature
| Feature | Sotto | PromptSmart Pro |
|---|---|---|
| On a Mac | A native Mac app. The prompter hangs from the notch, or from the top centre on Macs without one. macOS 14 or later. | The iPad app runs on Macs with Apple silicon; its listing says "Designed for iPad". A separate Studio Edition for Mac and Windows needs an account and a subscription. |
| iPhone and iPad | Yes, iOS 17 or later. The reading line sits just under the front camera. | Yes, iOS 16 or later. Selfie Mode keeps the text next to the camera. |
| Android and Windows | No. | Android app. Windows through Studio Edition. |
| How it scrolls | At the speed you set, while you speak. It waits when you go quiet. It doesn't follow individual words. | VoiceTrack follows your words, stops when you pause or improvise, and picks up when you return to the script. English only, says the App Store listing. |
| Speech processing | None. The microphone measures loudness, and nothing is transcribed. | Speech recognition runs on your device, with no internet needed. |
| Price | One payment, announced at launch. No subscription and no in-app purchases. | App Store: $29.99 plus in-app purchases. The Extended subscription adds remote control, file sync and Scroll Assist. Website plans: Starter $9.99 a month or $99.99 a year, Team $19.99 a month or $199.99 a year. |
| Account | None. | Studio Edition needs a PromptSmart account. Scripts can sync through the My PromptSmart portal. |
| Remote control | The iPhone app controls the Mac: play, pause, speed, text size and sending scripts. Direct over Wi-Fi or Bluetooth, with a 4-digit pairing code. | With the Extended subscription, or as a separate purchase. Team plans add browser-based Control Room sessions. |
| Video recording | No. Record with your camera app, Zoom, OBS or anything else while Sotto prompts. | Yes, HD video in Selfie Mode. |
| Screen sharing | The prompter is a private window, which asks macOS to keep it out of screen shares and recordings. | Its site describes a semi-transparent window over your meeting. We found no claim that it's hidden from screen shares. |
| Data collected | Nothing. No analytics, no servers. | The App Store label lists email address, user ID, device ID, product interaction, crash and performance data, and other user content, all marked "not linked to you". |
| Importing scripts | Word, PDF, Markdown and text files, and Google Docs links. On iPhone, RTF and files from Google Drive, Dropbox and iCloud Drive too. | Import and export through Google Drive, OneDrive, Box, Dropbox and iCloud. |

Where PromptSmart is ahead
VoiceTrack is real word tracking. It listens for the words in your script, so if you skip a paragraph, slow down for emphasis or go off script for a minute, it finds your place again. Sotto doesn't do that. It hears that you're talking, not what you're saying, so it scrolls at a steady speed while you speak. If you speed up, nudge it faster with ⌃⌥ → or the iPhone remote.
PromptSmart also records video, works on Android and Windows, and has team plans. If you need any of those, it's the better fit.
Where Sotto is different
It lives under your Mac's camera
Sotto is built for the Mac first. The script hangs from the notch, a few millimetres from the lens, so your eyes stay on the camera during calls and recordings. Shortcuts like ⌃⌥ Space work from any app, and on a Mac mini or Mac Studio you can pick your webcam's microphone.
Nothing to sign up for, nothing collected
There's no account, no cloud and no analytics. Voice pacing only measures how loud the room is, so no audio is recorded, transcribed or sent anywhere, not even for processing.
You pay once
PromptSmart's Starter plan is $99.99 a year, or $299.97 over three years. Sotto is a one-time purchase with every feature included.
Moving your scripts over
PromptSmart exports scripts to cloud drives such as Google Drive, Dropbox and iCloud. From there, drop Word, PDF, Markdown or text files into Sotto's library, paste a Google Docs link, or copy and paste the text. On iPhone, you can also use "Open in Sotto" from Files or another app.
Questions
Does Sotto follow my words like VoiceTrack?
No. Sotto scrolls at the speed you set while it hears you speaking, and waits when you stop. It never listens to the words themselves, which is why nothing about your voice leaves the device.
Does Sotto work on Windows or Android?
No. Sotto is for Mac, iPhone and iPad.
