From a link
to a motion video.
Tween reads your source, pulls the copy, screenshots, logo and brand colors, then writes a story arc — hook, reveal, payoff — and animates every frame.
A short brief.
A clear direction.
Like briefing a great motion designer — not filling in a template editor. Leave anything on Auto and Tween decides.
Start with your content
An App Store name, a website, a topic, a profile, an article or your own files.
Pick the kind of video
Product video, explainer, data story, announcement, case study, event — suggested from your brief.
Shape the output
Aspect ratio, 10 to 30 seconds, tone and visual style. Brand colors are picked up for you.
Edit by just asking
Preview instantly, ask for changes in plain words, export MP4. Every version is kept.
Styles with a
grammar, not a skin.
Each style changes the motion, texture, composition and transitions — not just the colors and fonts.
Product UI
Device frames, screen choreography, focus highlights.
Mixed media
Photos, cut-outs, bold type and scribbled notes.
Paper cut-out
Layered paper, soft shadows, handmade jitter.
Vox-style
Editorial collage, maps, callouts and timelines.
Kinetic type
Text as the main material, paced by language.
Data & infographic
Charts, stat reveals, before/after, labeled diagrams.
Hand drawn
Marker lines, circles and arrows that draw themselves.
Generative
Particles, fields and grids, built from code.
One video.Every language.
Translate a finished video in a tap. Copy reads naturally, brand names stay put, and line breaks, sizes and timing adapt — the motion stays exactly as designed.
No need to recreate the project.
Pay per video.
Not per month.
Reference web prices in USD. iPhone prices and availability are shown in the app before purchase.
