Screenwriter

About Screenwriter
Screenwriter is a no-code UI automation tool that enables users to create and manage UI tests without writing code. It uses AI models to generate autonomous agents that interact with applications, allowing users to describe user flows in plain English. Test runs can be reviewed directly within the app, and the tool provides features to manage and scale entire test suites on its own infrastructure. Screenwriter supports integration with CI/CD pipelines through GitHub Actions and CircleCI, making it suitable for teams looking to automate UI testing in their development workflows. The platform is designed for QA engineers, developers, and product teams who need to validate application interfaces efficiently without manual scripting. It simplifies the process of UI testing by abstracting technical complexity and focusing on user-friendly descriptions of expected interactions.
