PromptSmart is a teleprompter app whose VoiceTrack speech recognition scrolls a script as you speak, and its store listing centers on recording video. The Aitho AI slide teleprompter is built around a slide deck: your script follows your voice, your slides advance as you reach each slide's words, and a private copilot can draft an answer to an audience question on your own screen. If you are recording a video, start with PromptSmart's strengths. If you are presenting slides to a room or a call, Aitho is designed for that job.
Start with your situation
Most people comparing these two tools have a specific moment coming up. Maybe it is a recorded update for your team, where you read a script straight into the lens. Maybe it is a pitch, a lecture, or a quarterly review, where you stand next to your slides and need to keep your place while clicking through them and fielding questions afterward.
Those are different jobs. A camera script needs smooth scrolling close to the lens. A slide talk needs your words, your slides, and the questions at the end to stay in step, while the audience sees only the slides. The right tool is the one built for the job in front of you.
What PromptSmart is built for
According to PromptSmart's own site and store listing (facts checked on 2026-09-26):
- VoiceTrack speech recognition scrolls your script as you speak, stops when you pause or improvise, and resumes when you return to the script.
- PromptSmart says VoiceTrack runs on your computer or mobile device and does not require the internet.
- There are apps for iPhone and iPad (PromptSmart Pro and PromptSmart+) and for Android (PromptSmart+), plus a Studio Edition for Mac, Windows and Linux.
- PromptSmart offers a Remote Control app and a web-based control room as paid options, and its Pro App Store listing describes an optional paid Extended subscription that adds File Sync and Scroll Assist.
- The listing positions it for recording video and for people who speak publicly, including as a practice tool or at live speaking engagements.
For a creator or spokesperson reading to a camera, that is a focused, mature toolset.
What Aitho is built for
Aitho starts from the deck you already made, not from a blank script.
- Bring your slides as they are. Import a PDF or PowerPoint file. Keynote and Google Slides work by exporting to PDF or PowerPoint first. Aitho never edits your slides.
- A first-draft script if you need one. Aitho can draft a first-pass speaker script from your slides, which you then edit into your own words. Or paste your own.
- Your script follows your voice. The script scrolls as you speak and highlights the word you are on.
- Slides advance as you reach their words. When you speak into the next slide's section, the slide moves, so you are not reaching for a clicker mid-sentence.
- A private presenter view, a slides-only audience view. Your script and answers stay on your screen. The room or the call sees the Audience Stage, which shows only your slides. On Zoom, Teams, or Meet from a computer, you share the Stage window rather than your whole screen.
- A private Q&A copilot. When a question comes, the copilot drafts an answer from your deck and the documents you attach, shown only on your screen. If your material does not cover the question, it may run a web search and cite the source; otherwise it marks the answer as unverified.

Where your voice goes, and what works offline
If you present somewhere with poor Wi-Fi, this matters. PromptSmart says VoiceTrack does not need the internet.
For Aitho, it depends on where you run it. In the iPhone app: "On iPhone and iPad, the Aitho app runs Apple's on-device speech recognizer: the audio for voice-following stays on the phone and is not sent to Aitho or to Apple, so voice-following works offline. Asking the private Q&A by voice is different: that short recording goes to Aitho's own server to be transcribed and is then discarded, and the answer needs a connection."
On Android, in a desktop browser, or in a phone browser, voice-following needs a connection. If the connection drops, an opened talk keeps its slides and script and you can switch to auto-scroll. Aitho's help page lists exactly where the audio goes on each platform.
When PromptSmart is the better fit
- You mostly record to camera, with the phone or tablet in a teleprompter rig.
- You want voice-following that does not depend on a connection on every device you own.
- You want a dedicated remote control app and a Windows desktop edition.
When Aitho is the better fit
- Your talk is built on slides, and you want the slides to move with you instead of with a clicker.
- You present on a video call from one computer and want your script on your screen while the call sees only the slides.
- The questions at the end worry you more than the talk itself, and you want a draft answer from your own deck and documents on your screen when one comes.
If the talk is judged or has rules about assistance (a pitch competition, a defense, an exam), check the rules first. Using Aitho to rehearse is always fine.
Try it on the talk you already have
The fastest test is your real deck. Open Aitho in a browser at aitho.app or in the iPhone or Android app, import the PDF or PowerPoint you are presenting next, and read the first two slides out loud. You will know within a minute whether it follows you. Voice-following and slide advance are free; the Free plan includes 3 private Q&A answers to try the copilot.
Frequently asked questions
Is Aitho a PromptSmart alternative for presentations?
If your presentation is built on slides, yes. Aitho imports your PDF or PowerPoint deck, follows your voice through your script, advances the slides as you reach their words, and keeps your script on your screen while the audience sees only the slides.
Does Aitho work offline like PromptSmart?
Partly. In the iPhone app, voice-following runs on the phone and works offline. On Android and in a browser, voice-following needs a connection, and the Q&A copilot needs a connection everywhere.
Can I use Aitho for video recording?
Aitho is designed for presenting slides live, in a room or on a call. For reading a script to a camera in a rig, a camera teleprompter like PromptSmart is the more direct fit.
