Sayscroll
Sayscroll
A browser-based AI teleprompter that uses real-time speech recognition to scroll your script at your actual speaking pace, in 60+ languages.
Key features
- Voice-Tracked Scrolling: Real-time speech recognition fades out each word as it is spoken and keeps your place centered, replacing fixed-speed scrolling entirely.
- Off-Script Handling: The prompter pauses when you improvise and automatically re-locks onto the text when you return, even if you skip to another section.
- 60+ Language Support: Works with English, Spanish, German, French, Swedish, Greek, and dozens more, including scripts that mix languages in the same paragraph.
- Built-In Video Recorder: Record camera and mic takes directly in the teleprompter with the script overlaid on the video or shown in split-screen.
- Local Recording Storage: Recordings save straight to your device and the script never leaves it; only audio is streamed for transcription.
- Beam-Splitter Mirroring: Horizontal and vertical mirroring plus fullscreen output for professional hardware teleprompter screens.
- Studio Reading Controls: Adjustable text size, column width, paragraph alignment, and black or white background for comfortable reading on set.
- Usage-Based Billing: Only live microphone time counts toward the monthly hour allowance, and silence does not consume minutes.
Best for

- Live Presentations and Demos: Jump between script sections during a live demo and have the prompter find your position each time.
- Multilingual Content: Deliver a script that mixes two languages in the same paragraph without the prompter losing track.
- Church and Event Media: Replace a hardware prompter and a volunteer operator with a prompter that reads along with the speaker.
- Online Course Production: Record lecture segments where the speaker pauses often to find words, without a fixed scroll running ahead.
- Podcast and Webinar Delivery: Keep sponsor reads and intros on script while sounding conversational rather than read.
