Swap the top and bottom text blocks in bilingual SRT subtitles — structurally, without language detection or guessing.
Upload a talking video and get it back with captions burned in, plus SRT, VTT and a plain transcript. No install, no API key. Chinese (Traditional, Taiwan) or English. Keeps your video's shape, or vertical 9:16 with black bars. Fix captions by chatting: edit a line, add a missed sentence, replace a misheard word everywhere, shift timing, change size or position. Up to 500 MB / 20 minutes.
Fix SRT subtitle timing with precise offset, FPS conversion, and two-anchor drift correction. Deterministic, local, and fail-safe — no AI guessing.
Free rough cut for videos up to 10 minutes: puts the strongest moment at the start as a hook, removes long silences while keeping the story in order, and writes SRT subtitles. Runs offline. Upgrade to AI Story Editor Pro for bilingual subtitles, filler and retake removal, editor timelines and no length limit.
Turn raw footage into a rough cut that keeps the whole story: the strongest moments go up front as a cold open, dead air, filler words and failed retakes are cut, and subtitles are added. Foreign speakers automatically get bilingual subtitles. Exports MP4, SRT, Premiere/DaVinci/Final Cut timelines and a 9:16 short. Runs offline.
영상이나 음성 파일을 채팅에 올리면 SRT·VTT 자막과 자막을 입힌 MP4가 돌아옵니다. 영어·일본어 등 번역 자막도 같이 만들 수 있고, 번역 API 키는 필요 없습니다. 받아쓴 문장을 줄 길이·초당 글자 수 기준으로 다시 나눠 읽기 편하게 만들고, 번역본의 큐 수나 타임코드가 원본과 다르면 파일을 만들지 않습니다. 설치 없이 Capafy 클라우드에서 돌아갑니다. 2분 25초 영상은 음성 인식 9초, 자막 입히기 29초 걸렸습니다(2 CPU). 주간 플랜은 무료 체험 기간으로 시작합니다.
Paste a public YouTube link and get a clean, quotable full transcript plus a chapter-by-chapter summary in your language, saved to your machine. One playlist URL batch-extracts a whole series; blocked videos are skipped and reported with reasons. Compare quotes across videos as 'Video title [MM:SS]'. A 147-line script strips auto-caption duplicates; outputs txt, timestamped md, SRT, VTT. Runs locally in Claude Code, unlimited use. Captioned public videos only — no STT, no private videos.
