Why creators pick Scriptfox
Glance away, ad-lib a thought, then drop back into your lines — the prompter holds its place and re-syncs instead of racing ahead.
Your hands are on the camera or a prop. Say 'Hey Fox' to start, pause, jump sections, or change pace without reaching for keys.
Scriptfox runs in any browser, as a Windows desktop app with a built-in screen recorder and editor, and as an iPhone app — one account, scripts synced everywhere.
Scriptfox knows your script's structure, so it maps YouTube retention to your Hook, Intro, and CTA — telling you where viewers actually leave.
Frequently asked questions
What is the main difference between Scriptfox and PromptSmart?
Both follow your voice as you read. PromptSmart is primarily a mobile teleprompter app (iOS and Android) with its patented VoiceTrack scrolling. Scriptfox is built for the whole creator workflow: voice tracking that re-syncs when you go off-script, hands-free 'Hey Fox' commands, a browser and Windows desktop app with a screen recorder and editor, an iPhone app, YouTube retention analytics mapped to your script, and an AI writing partner in the editor.
Does PromptSmart follow your voice like Scriptfox does?
Yes — PromptSmart's VoiceTrack technology scrolls as you speak, stops when you pause or improvise, and resumes when you return to the script. Scriptfox's matcher takes the same idea further with accent calibration, custom vocabulary for niche terms, click-any-word instant resync, and hands-free voice commands on top of the tracking.
