Mac
Word-level captions & subtitles for Mac. Word-by-word highlights, on-device translation, a real timeline. Runs on your Neural Engine. $39.99 once, yours forever.
Cutline adds word-level captions and subtitles to any video — entirely on your Mac.
It runs on Apple's Neural Engine: no uploads, no queues, no subscriptions. The same Whisper model the cloud apps use, without the round trip. A two-minute clip transcribes in seconds, locally, with sub-100ms word-level timing.
WORD-BY-WORD CAPTIONS THAT POP
Highlight each word as it's spoken — recolor the active word, or put it in an animated pill that pops in sync with the audio. The viral, retention-boosting look creators use, generated automatically from precise word-level timestamps.
A REAL EDITOR, NOT JUST A GENERATOR
Most caption tools stop at "generate." Cutline gives you a proper timeline: trim in and out, scrub, change playback speed, split and merge caption blocks, retime them, and fix any word inline — with real undo and redo. Drag the caption anywhere on the frame, and preview against platform safe zones so text never lands under a like button.
MAKE IT YOURS
Eight curated caption styles — Anchor, Cinema, Headline, Pulse, Quiet, Statement, Studio, Subtitle — then customize everything (font, size, color, outline, highlight, pills, caps) and save unlimited styles of your own. Upload any TrueType or OpenType font; it stays local and renders exactly right.
SPEAKS EVERY LANGUAGE
Caption non-English video in around 99 languages with automatic language detection, then add an on-device translated subtitle line in 20+ languages. Right-to-left scripts like Arabic render correctly. All translation happens on your Mac.
PAY ONCE. OWN IT.
$39.99 one-time. No monthly bill, no renewal anxiety, no tier upsells. 14-day free trial, no credit card.
LOCAL FIRST, ALWAYS
Your video never leaves your Mac — not for transcription, not for rendering, not for anything. No account, no analytics, no data collected. For editors under NDA, journalists with sensitive footage, or agencies handling client work pre-release, that's the only acceptable option.

BUILT BY A CREATOR
I was paying Adobe $60 a month and watching it get worse, so I switched to software I could actually own. Then I looked at the caption tools I was still renting every month and realized nobody had built a focused, on-device, one-time version. So I did.

Cutline is for Mac (macOS 14+). Apple Silicon recommended for fastest transcription; translation requires macOS 15+.
