The editor that understands you

Talk to your edit.
Then refine it.

Previz is an AI-native video editor where you describe what you want in plain language, and an intelligent agent orchestrates the edit. Then you fine-tune every frame on a real timeline.

Add animated captions that pop in word-by-word. Match the energy of the beat drop at 0:14.
Done. I've synced word-level captions to the audio peaks. The drop at 0:14 triggers a scale + glow effect. Check the caption track.

Two modes, one surface.

Every great edit starts with intent. Previz lets you express it in words, then perfect it by hand.

Chat-Driven Editing

Describe what you want in natural language. The editing agent plans and executes across all tracks: video cuts, transitions, captions, overlays, and music sync. One prompt can orchestrate a complex multi-track edit.

Real Timeline Control

Every agent action maps to the timeline. Drag, trim, split, and adjust with the precision you expect from a professional editor. The AI gets you 80%. You finish the last 20% by hand.

Smart Captions

Word-level caption styling, animation, and placement. Sync to audio peaks. Apply motion presets. The agent handles timing. You control the look. Every caption is editable on the timeline.

Multi-Track Composition

Video, audio, captions, overlays, music. Layered tracks that behave like a real editor, not a toy generator. The chat agent understands track relationships and edits across them coherently.

Not a generator.
An editor.

Most AI video tools generate content from scratch. Previz starts with your footage, your vision, your taste. The agent handles the labor. You keep the creative control.

The future of editing is a conversation.

Previz is building the creative tool that sits between CapCut and the next wave of AI-native software. Not just "generate a video." Collaborate with an intelligent editor, then refine every frame.
