Introduction

Zorro is the AI testing product of Narrative, a company in Y Combinator’s Winter 2023 batch. It runs AI bug bashes and AI regression tests on your pull requests.

Its agents proactively explore the app like a manual QA tester, hunting for unexpected edge cases, content mismatches, broken layouts, visual flaws and functional bugs. There are no test cases to write, map or update; the agents work out paths dynamically as the UI changes. A planning agent fans work out across multiple browsers.

Each bug comes with a full recording, console logs and step-by-step breadcrumbs, and findings can be shared with product and engineering to categorise and resolve together.

Launch and background: Y Combinator’s company directory lists Narrative in its Winter 2023 batch, with the one-liner “AI agents for end-to-end testing”.
