AI-augmented quality platform for web, mobile, API and desktop testing
Generate automation scripts and test cases from natural language or tickets, get plain-language explanations, and let self-healing retry alternative locators when the UI changes so suites keep running through small front-end edits.
Cover web, API, mobile (Android and iOS) and Windows desktop applications inside one authoring environment, with record-and-playback, data-driven testing, BDD/Cucumber support and a dual-mode debugger.
Plan cycles, map requirements to cases, track coverage and flakiness, link defects in Jira, and gate releases using a shared live report that unifies manual, automated and AI-generated runs.
Run suites in parallel on real browsers, real iOS and Android devices, or your own CI runners and on-premise Runtime Engine, with lane-based parallel execution for faster coverage.

Red-team and evaluate AI agents before they reach production
Adversarial evaluation of agents to surface unsafe, non-compliant or unreliable behaviour before they run against real users and real money.
Measure and track how much fine-tuning private models with LangTrain improves accuracy for your specific domain.
Verify that agent responses are repeatable and reliable enough for regulated workflows such as clinical, lending or claims decisions.
Evaluate agents that work across text, voice, vision and other modalities rather than text alone.
