The teleprompter that waits for you. Soyla helps you read comfortably while recording yourself. Write or paste a script, or open one from a document, make it easy on your eyes, and let it move the way you like: at a steady pace you choose, by hand, or following your voice. MAKE ROOM FOR YOUR WORDS Create, rename, and organize scripts in your own library. Start one from a Word (.docx), RTF, Markdown, or plain-text document; headings, bullets, bold, and italic come along, and the file is read on your device. Your edits save automatically, with undo and redo. Add sections, pauses, breaths, emphasis, notes, and bookmarks from a menu, with no syntax to learn. Compare earlier versions of a script and restore one. READ AT YOUR OWN PACE Scroll from 50 to 260 words per minute, by lines per minute, or to finish in a set time. Step line by line, jump to any section, or repeat a passage while you rehearse. Adjust text size, typeface, spacing, line width, colors, and reading position, and mirror the prompt for a teleprompter rig. FOLLOW YOUR VOICE Optional. The script keeps up as you speak, holds when you pause or go off script, and lets you tap any line to pick up from there. Speech is recognized on your device and never sent anywhere. Where on-device recognition isn't available, the script keeps the pace you set. RECORD WITHOUT LOSING YOUR PLACE Record with the front or rear camera and your script on screen. Choose resolution, frame rate, and HEVC, set focus and exposure, and check your sound with a live level meter. Pause or repeat the script while the video keeps recording. For a retake, start from any sentence instead of the top, and let the take stop on its own a few seconds after your last line. REVIEW, EXPORT, AND SHARE Play back a take, keep it, or delete it and try again. Trim it with two handles, and Soyla offers to cut the quiet before your first word and after your last; the original is never changed. Make versions for vertical, square, or wide video, with even loudness, less background hiss, and a cover image, then share them or save them to Photos. Your videos have no prompt overlay or watermark. IN YOUR LANGUAGE Soyla's screens are in 16 languages, and paces feel the same in each, including scripts in Chinese, Japanese, and Korean. Voice following works in the languages your device can recognize on its own: more than 50 on iOS 26 and macOS 26, fewer on earlier versions. A LOCAL LIBRARY No account and no ads. Scripts and recordings stay in the app's local storage unless you choose to share them or your operating system includes them in backups or device transfers. The app does not upload your library. Export or delete everything from About. Editing, prompting, recording, and playback work offline. Recording requires a camera and microphone access. SOYLA PRO Writing, editing, reading, and recording need Soyla Pro: yearly, with a free week for new subscribers, monthly, or Lifetime, paid once. Prices are shown in the app before you buy. Without it, you can still open, share, export, and delete what you've made. If you used Soyla before it had plans, it all stays free for you. Payment is charged to your Apple Account. A subscription renews automatically unless you cancel it at least 24 hours before the trial or the current period ends; the renewal is charged within the 24 hours before then. Manage or cancel it in your Apple Account settings. Lifetime is charged once and never renews.

Verdict
The clearest difference is rating: Soyla at 5.0 against Luminosys's 4.3. Soyla also leads on ads (none vs shown) and update cadence (every 3 days vs every 19 months). Luminosys's advantage is in-app purchases (none vs 3) and ratings volume (10 vs 1). On price and iOS requirement there is nothing between them.
