Runway

Runway is a web-based suite for generating and editing video, images and audio with AI, built on its own models such as the Gen-4.5 video model. From one workspace you can turn text or images into video clips, edit existing footage, animate characters and generate stills, with apps for iOS and Android as well as the browser. It includes an agent for creating with plain-language instructions, character and performance tools, custom voice clones, brand kits, 4K upscaling and HDR or ProRes output on higher plans. Runway Ads connects to Meta, Google and TikTok to generate ad variations, and an MCP server and API let developers use Runway's models in their own apps. It suits filmmakers, video editors, marketers and agencies. A free plan gives a one-off 125 credits to try a selection of models, and paid plans from $12 a month (billed yearly) add monthly credits, more storage and no watermarks.
