Dubl: Video Editor & Captions

Shot a talking-head video on your phone — one take or ten. Dubl listens to the recording, picks your best takes and hands you a finished vertical video with captions, stickers and clean sound. How it works 1. Pick your files and put them in the order you shot them. 2. The AI listens to the recording, finds your takes and transcribes them. 3. Mark your best takes and arrange the lines — hook first, even if you shot it last. 4. Get your finished video and save it to Photos. What the app does, not you — Finds take boundaries by the pauses between phrases. — Suggests your best take and explains why it's the one. — Adds word-level captions and stickers with numbers and names. — Crops to vertical, adds sound and levels the volume. Your footage stays on your phone Only the audio track is sent off for analysis — your video never leaves your device. Who it's for For people who shoot vertical videos themselves and re-record the same line two or three times: experts, teachers, course creators. Dubl doesn't choose your edit for you — the order of your files and lines is up to you; it handles the transcription, cutting and styling.
