Arcade vs. Karumi

Arcade is an AI video generator for marketing teams. Describe the video you want, and Arcade writes the script, builds the scenes and adds voiceover, using your real product, brand and messaging instead of stock footage or avatars. Every scene stays editable. Change a line, a visual or the voiceover directly or by chat, without regenerating the whole video. Brand Kits apply your logos, colors, fonts and tone automatically, and Arcade remembers your preferences, so each video gets closer on the first try.

Karumi is an AI-powered product expert that joins your video calls and helps teams deliver clear, consistent product demos without extra prep work. Instead of relying on scripted walkthroughs or pre-recorded videos, Karumi can run a live, agentic demo of your product, adapt to what the customer wants to see, and answer questions in real time. It behaves like a knowledgeable teammate who always knows how the product works and can guide people through the experience step by step.
