Luma AI Wants You to Direct, Not Just Prompt
Luma has grown from a five-second video curiosity into a serious creative workbench. Ray3.2 gives filmmakers real control, while the credit meter gives everyone a reason to plan before pressing generate.
Runway Put a Film Studio in Your Browser. Bring a Shot List.
Runway can turn a sentence, a still or an existing clip into footage worth cutting. The catch is wonderfully old-fashioned: good direction still matters, and every bad take has a price.
Moonvalley Gives AI Video a Director's Chair
Marey trades prompt roulette for camera paths, keyframes and motion references, all built on licensed footage. It is a thoughtful pitch to filmmakers - with rough edges, a shifting company story and a demo-reel-sized question mark.
Hailuo AI Makes the First Cut. You Still Direct.
MiniMax’s pocket video studio can turn a prompt and a pile of references into a polished short with sound. The trick is knowing when to applaud the take, when to regenerate it, and when to call an editor.
Kling AI Makes the Shot. Mind the Subscription.
Kuaishou’s video machine can turn a reference image into a multilingual, multi-shot clip with native sound and crisp motion. The pictures impress; the credit meter and a bruising record of billing complaints demand a careful trial run.
Craze
Craze is a Y Combinator (S22) company that reinvented itself into an AI video maker at craze.ai - a tool that plans, edits and turns creative direction into finished videos. Founded in 2022 by Kabir Nagral and Deepit Patil, Craze began as an HR, payroll and compliance platform for Indian founders before shutting that product down in 2025 and rebuilding around AI, first as a general 'do things with AI' agent layer and now as a creative video studio.
Yarn (YC W24)
Yarn is an AI-native platform that lets go-to-market teams make agency-quality product, sales, and marketing videos in minutes instead of weeks. Founded during Y Combinator's Winter 2024 batch by Jasper Story and Nicole Atack, Yarn treats video like a document: you write a script, and its stack of AI tools handles voiceovers, screen recordings, part-synthetic talking heads, brand-styled overlays, and generative footage. The pitch is speed and cost - videos that would take an agency weeks and thousands of dollars, produced in-house in under 20 minutes.

Decart is a frontier AI lab building real-time world models and the low-latency infrastructure that runs them. Its systems - Oasis, Lucy and the DOS optimization stack - generate and transform live video at millisecond latency, turning video games, livestreams and cameras into promptable, interactive worlds.
