qtrl.ai FAQ

How does qtrl.ai's AI differ from other "autonomous" testing tools?

Alert: Many tools force a risky, AI-first approach where the AI makes opaque decisions. qtrl.ai is built on a principle of "permissioned autonomy." Its AI agents operate strictly within rules and instructions you define. You maintain full visibility into every action, and all AI-generated tests are reviewable and approvable. It's AI augmentation, not AI replacement, designed to earn trust through transparency and control.

Can we use qtrl.ai if we currently only do manual testing?

Absolutely, and that's the recommended starting point. qtrl.ai's platform is designed for progression. You can begin by using its robust test management features to organize and execute your manual test cases and plans. This gives you immediate value and a structured foundation. When your team is ready, you can gradually introduce AI-powered automation for specific flows, all within the same centralized platform.

Is our data secure, especially when using AI agents?

Security is non-negotiable. qtrl.ai is built with enterprise-grade safeguards. For AI operations, your application secrets and sensitive environment variables are encrypted and never exposed to the AI agents. The platform operates with full audit trails and is designed for compliance. You maintain sovereignty over your data and test assets at all times, with granular control over who can access and trigger automation.

How does qtrl.ai handle tests when our application UI changes?

This is a classic automation pain point. qtrl.ai's Adaptive Memory and intelligent agents are designed for resilience. The system learns from your application and past test executions. When changes occur, the AI can often suggest maintenance actions or adapt tests based on context. Furthermore, because you start with high-level instructions (e.g., "log in as a customer"), rather than brittle, code-level selectors, tests are more durable and easier to update.
