iArt
iArt.ai transforms text prompts, images, PDFs, slides, audio, or web links into complete motion graphics videos. Instead of manually keyframing in After Effects, you simply describe your vision in everyday language, and an AI agent creates the animation scene by scene.
It offers three engines: Motion Design (where animation is written as code, ensuring precise text spelling and charts based on real numbers), AI Video (for a cinematic look using generative methods), and Animation (where each frame is drawn in JavaScript on a canvas, exportable as transparent WebM for lower thirds and OBS overlays).
You can make edits by describing the changes you want ("make the title two seconds shorter"), and the system will re-render the video with the rest of the content intact. It includes built-in voiceovers in nine languages, voice cloning available on paid plans, and background music.
Creating a 3–5 second clip takes about a minute, while a multi-scene sequence can take two to three minutes. You can start for free with a $2 signup credit, no credit card required. The Pro plan is $20/month (1080p, no watermark), and the Ultra plan is $50/month (4K).
