Stop looking away
from the lens.
PromptFlow puts your script where you're already filming — floating over any camera app, or inside its own 4K studio — and scrolls at the pace you actually speak.
WHAT YOU GET
Built for people who film themselves
A prompter, a camera, and a script editor that understand each other — so a shoot day is write, read, record, done.
Floating overlay
Run the prompter over any app — your camera, Instagram, TikTok, a video call. Drag it, pinch to resize, fade it, or collapse it to a bubble between takes.
Built-in 4K studio
Record with the script hovering under the lens. Tap to focus, pinch to zoom, exposure, torch, framing grid, and 16:9 / 4:3 / 1:1 crops.
Voice sync
The prompter listens and keeps your current line in the reading band. Speed up, slow down, pause to think — the script follows you, not the other way around.
Takes that stay organised
Every recording is linked back to the script it was read from, with thumbnails, duration and quality — so you always know which take is which.
Import anything
Bring in .txt, .docx, .pdf and .md. Markdown headings become prompter sections automatically, so an outlined document arrives ready to film.
Made for real rigs
Mirroring for beam-splitter glass, volume keys and Bluetooth clickers for speed and play/pause, and a start-delay countdown to get in position.
SCRIPT MARKERS
Write it like a script, not a wall of text
Markers tell the prompter what to do — and never count as words you speak, so your estimated read time and voice sync stay accurate.
## SectionSection headerShows as a heading, and gives you a jump point you can skip back to while filming.
[[pause]]Stop and waitScrolling halts when the line reaches the reading band. Tap to carry on — good for ad-libs.
[[pause 3s]]Timed holdSame, but counts down and resumes on its own.
[[b-roll: …]]Stage directionA dim note to yourself — camera moves, props, reminders. Shown, never spoken.
A LOOK AROUND
Every surface, one prompter
Speed and reading position follow you between the studio and the overlay — switch surfaces mid-shoot without losing your place.
PRIVACY
Your scripts never leave your phone
No account. No cloud. No analytics, ads or trackers. Scripts and settings live in local storage on your device, and recordings save straight to your own gallery. The app doesn't need the internet at all — except to fetch a font you pick.
