Start with what you need.
Four steps, then post.
No timeline to set up. No project files to manage.
Step 1
Drop in a clip
One video file, straight from your camera roll. The file stays on your device.
Step 2
Speech becomes timed words
The speech model runs in your browser and stamps every word with its moment. Fix a name or drop a filler before anything is styled.
Step 3
Choose the look, place the box
Start from 150 animated looks. Drag the caption box clear of faces and buttons, then tune the hero word and the body line apart.
Step 4
Export the finished video
The same renderer that showed you the preview burns the captions into a 1080p vertical MP4. What you saw is what posts.
One long take, cut into clips worth posting.
The Clipper reads your transcript and proposes the segments worth clipping: measured suggestions from the speech between silences, or the AI Clipping Studio’s ranked moments. Trim the edges, create a clip, and it becomes its own captioned project, ready to style and post.
The AI ranks moments with an Editorial score — an estimate, never a performance prediction — and the measured suggestions show the signals behind their order. Your source video is not re-encoded or cut; a clip is a range on the same file, kept on your device. The separate AI Clipper section compares every clip against the whole video, and its runs resume where they stopped.

A file in, a transcript out.
Transcribe turns a video or audio file into a timed transcript, in 14 languages, with the speech model running in your browser. Copy it, or download it as TXT, SRT or VTT.
Open TranscribeMotion Studio: graphics that move.
Subscribe pills, follow cards, counters and titles — animated graphics you customise with your own words and colour, then drop into a project. These four are playing live, exactly as they render in your video.
Open Motion StudioDescribe the edit. Check the plan. Keep what works.
Choose a look, add a line of instruction if you like, and AI Edit drafts the whole edit — the caption look, punch-in zooms, key words and a hook — as a checklist. Nothing is applied until you approve it, and every step can be previewed and undone.
Try AI EditYou stay in charge of every word.
The first pass is automatic. After that, every word, break, position and motion curve is yours to change.
Move the caption box
Drag and resize the caption region anywhere in the frame, clear of faces, product shots or platform buttons. The export honours it to the pixel.
Re-cut the timing
A word-level timeline lets you nudge any word's in and out points when the delivery needs a different beat than the transcript suggests.
Fix the transcript first
Correct names, drop filler words and merge fragments before styling, so the animation never amplifies a typo.
Style the hero word apart
The emphasized word and the supporting line carry their own fonts, sizes and colours. Tune one without touching the other.
Every export is saved
Each render lands in the project's export history with its settings, so last week's look is one click to reproduce.
