AI Video Studio

Your next video shouldn't cost a studio.

CastFree turns a script into a publish-ready YouTube video — AI avatars, voiceovers, captions, B-roll, and all of it stitched together in one pipeline. No crew. No subscription stack. Just your laptop and electricity.

One pipeline.
Everything else.

Most creators cobble together five tools to make one video. CastFree is the one tool that replaces them all.

01

Script

Type your idea or paste an outline. CastFree's AI sharpens it into a YouTube-ready script — hook, body, CTA built in.

// Your script, refined hook: "Stop scrolling." body: "Here's how AI video works..." cta: "Subscribe."
02

Avatar + Voice

Pick an AI presenter or create your own. Natural voiceovers in 40+ languages — no microphone, no takes, no editor.

03

Captions + B-Roll

Auto-generated captions in your style. AI picks or generates B-roll that matches your narrative — no stock account needed.

Average US video production cost: $1,500-$5,000 per finished minute. YouTube creators making 2-3 videos/week were spending $6,000+/month on production. CastFree changes that.

YouTube-native,
not YouTube-agnostic.

Shorts from the same script

One script, one pipeline — CastFree extracts your best hooks and formats them as Shorts-ready clips. The long-form and the short-form come from the same source.

Algorithm-aware by default

Captions formatted for watch-time. Titles optimized for CTR. Timestamps auto-generated. CastFree thinks like a YouTube creator, not a video editor.

Consistency at scale

Your brand, your voice, your style — preserved across every video. Not a one-off tool, but the production system you grow a channel around.

Stop paying for videos.
Start making them.

The tools exist. The models exist. What's missing is the studio that puts them together and runs itself. That's CastFree.
