If you are looking at PromptSmart, you are already sold on the idea that matters: a teleprompter should follow your voice rather than scroll at a guessed speed. PromptSmart's VoiceTrack and TellyPrompter's voice-following solve the same problem, so this comparison is about everything around that — platform, price model, and what each one does with the fact that it knows where you are in the script. We will be straight about where PromptSmart wins, because it does win some of this.
All PromptSmart details below are taken from PromptSmart's own published pages in August 2026. Pricing and features move, so check their site before deciding.
What PromptSmart is
PromptSmart is an app suite from Belleau Technologies, built around VoiceTrack — their patented speech-recognition scrolling, which follows as you speak, pauses when you improvise, and resumes when you return to the script. Their pages state that audio is processed locally on the device, with no internet connection required for VoiceTrack.
The suite spans native apps: PromptSmart+ for iOS and Android, a Studio Edition for Windows and macOS, and a web portal for editing scripts and syncing them across devices. As published on their pricing page in August 2026, the Starter Pack subscription is $9.99 a month or $99.99 a year and covers the mobile and desktop apps, web-based editing, cross-platform sync and remote control; a Team tier at $19.99 a month or $199.99 a year adds multiple remote control room sessions and nested folders, with an Enterprise tier above that. There is also a longstanding standalone Pro app on the iOS App Store.
Where PromptSmart wins
Being honest about this is the point of the article, so plainly:
Native apps and a hardware-friendly ecosystem. If your workflow is a tablet locked into a rig running a dedicated app, with 4K recording on the device and a separate remote-control app or web control room driving it, PromptSmart is built for exactly that shape of production. TellyPrompter runs in the browser and has no remote-control companion — your voice is the remote, which suits a solo shoot and does not suit a producer driving the prompter for someone else.
Team and studio features. Control rooms, cloned displays, nested folders, sub-user administration — if a prompter is shared infrastructure in your organisation, their Team and Enterprise tiers address that directly. TellyPrompter is built for one person recording themselves.
Desktop apps as apps. Their Studio Edition is installed software for Windows and macOS. TellyPrompter installs as a PWA from the browser, which we would argue is a feature, but if your environment requires a conventional installed application, theirs is one.
Where TellyPrompter differs
The free tier is the whole prompter. TellyPrompter's voice-following, all 34 languages, mirror mode, the script library, and in-app recording without a watermark are free, with no account on the path from pasting a script to running it. PromptSmart's cross-platform suite is a subscription. We do keep a paid tier for cloud sync — the tier design, and what stays free and why, is its own article.
Nothing to install, on anything. Any device with a modern browser is already the prompter — the phone in your rig, the oldest tablet in the drawer, the laptop you are reading this on. It installs as a PWA if you want it to, and after the first visit the prompter works offline.
What the following unlocks afterwards. Because TellyPrompter tracks the word you are saying, every take carries per-word timing — which becomes script-accurate SRT and VTT captions with no transcription pass, a post-take stumble report showing where the read broke, and a measured read-time from your own rehearsal. If captions and take review are part of your week, this is the practical difference between the two products.
Languages and reading faces. Thirty-four languages with automatic detection, full left-to-right and right-to-left support, and OpenDyslexic as a first-class script face with the same sizing and reading states as the default.
On privacy, the honest note is that this is not a differentiator between these two: PromptSmart states VoiceTrack processes audio locally, and for TellyPrompter, speech recognition runs on the device and the audio is never uploaded. Both products let you read without your voice leaving the machine, which is how it should be.
The honest limits, ours included
TellyPrompter's voice mode rides on the browser's speech recognition, which Firefox does not provide — constant and sound-level scrolling work there, but if Firefox is non-negotiable and voice-following is the point, a native app avoids that constraint entirely. Recognition quality is the browser's rather than ours, so it varies by platform, language and microphone. And there is no remote control, no control rooms, and no team administration, by design.
How to choose
Choose PromptSmart if a producer or remote operator drives your prompter, if your organisation needs team administration, or if you want a native-app suite with 4K in-device recording and an established hardware ecosystem around it.
Choose TellyPrompter if you are one person recording yourself, you want the voice-following idea without a subscription or an account, and the after-the-take work — captions, stumble review, read-times — is where your hours actually go. The wider comparison of the category sets both against the rest of the field, and the case for voice-following itself is made in full there. The fastest way to compare is also the cheapest: open TellyPrompter in a browser, paste a script, and read — it costs nothing and needs no sign-up to find out.
