BlackBox is a hybrid QA platform where AI agents and human testers share one board. Point it at any product URL — Opus 4.8 autonomously discovers the app's features and use-cases, generates a structured test plan, and executes cases in a real browser. AI agents mark pass/fail with evidence and confidence scores. When an agent can't confidently complete a case — judgment call, ambiguity, or blocker — it escalates and relays the case to a human tester with a full handoff brief and screenshot, instead of guessing. Humans resolve from the same live grid. The result: trustworthy QA at scale, where the AI knows its limits.
