01
The problem
A traditional audio ad costs thousands of dollars and days in a studio, and you get one version at a time. We designed a platform to generate multi-participant audio ads in seconds, then dynamically alter them based on each listener’s interests and location.
02
What we built
From a prompt to a finished ad
The prompt-to-ad flow, with dynamic audio segments that swap in by a listener’s location or interests.
A multitrack editor in the browser
A Web Audio editor for trimming, mixing and regenerating each AI voice, with a script editor that joins takes into one commercial.
Onboarding, billing and tests
Onboarding, trial billing with Stripe and Playwright end-to-end tests running in CI.
The brand, the deck and the sites
The brand guidelines, the pitch deck, and the sites for both Oyi, the company behind Adtwin, and Adtwin itself, in Next.js, with animated hero type and an auto-looping reel of playable sample ads.
