Dub's Steven Tey shared a 15-second launch video for the company's AI Reward Builder that he says Claude Opus 5.5 produced in one attempt. The clip reproduces Dub's interface and adds motion to a walkthrough of the tool, which converts a natural-language description of a partner incentive into a reward structure. The result is a firsthand product-team demonstration, not an independent test, and the post does not detail the prompt, preparation or editing behind the attempt.
