The AI video studio.
Describe it. Ship the video.

An AI agent turns your idea into a scene plan. You edit each beat and approve it. It renders a finished, narrated, cinematic explainer — all locally, in minutes.

How it works
From a sentence to a finished video.

No timeline wizardry, no After Effects. Three steps.

01

Describe it

Type a brief — “a 30-second explainer on black holes.” A local AI model drafts a scene-by-scene plan.

02

Edit & approve

Tweak headlines, charts, images, timing, and voice. Ask the agent to revise. Approve each stage when it’s right.

03

Render & ship

Export a real 1080p MP4 with cinematic motion graphics and narration. Save it, post it, done.

Why it's different
Built like a tool, not a SaaS.
🤖

Agentic, not a prompt box

A real production agent plans scenes, drafts narration, suggests imagery, and revises on request — you stay the director.

💻

Local-first & private

Your scripts and renders never leave your Mac. No cloud queue, no per-render billing, works offline.

Genuinely cinematic

Powered by the Remotion motion-graphics engine: animated titles, stat reveals, real bar & pie charts, cross-fades.

🎛️

A studio you control

Dual-track timeline, live preview, undo/redo, editable charts, selectable voices, and an approval gate at every stage.

🖼️

Real imagery

Pull free stock photos or AI-generated backgrounds per scene — pluggable sources, your keys, your choice.
