DevMotion

What is DevMotion?

DevMotion turns prompts into motion-designed videos. Open the editor in your browser, chat with Claude/Gemini/Kimi/Grok, and it builds the timeline — layers, keyframes, captions, backgrounds, 3D mockups. Or drive it from your IDE via the MCP server. Record your screen + cam, auto-caption and auto-dub in any language, generate B-roll with Seedance 2.0, and export once — DevMotion re-lays out for 16:9, 9:16 and 1:1 up to 4K. Free plan, no install, no credit card.
