Auto-generate test cases

Catch issues before going live

Simulate scenarios for higher accuracy

Run persona-specific test cycles

Auto-generate test cases from documents

Go from document to test library in one click

Quickly build comprehensive test libraries by ingesting your SOPs, product documents or website content no writing required. Each piece of content is instantly transformed into contextual test cases that reflect your latest updates, brand guidelines and policy changes.

Run persona-specific test cycles

Scalable and targeted testing for every agent deployment

Execute hundreds of conversational tests in parallel before every release. Choose scenarios by persona, channel or risk level whether it’s a first-time user raising a billing issue on WhatsApp or a returning customer navigating a product return across multiple languages. Plug testing into your CI/CD pipeline for real-time quality signals.

Scenario-based testing for real-world accuracy

Simulate potential user journeys from intent to resolution

Validate how your AI agent handles end-to-end conversations by simulating scenarios based on real or anticipated customer intents. Whether it’s onboarding a new user, handling a refund or resolving a complaint creating test flows that mimic actual user behavior and ensure accurate, brand-aligned responses every step of the way..

Actionable insights to optimize AI performance

Identify errors and analyze AI agent reasoning

Analyze high-level QA metrics like pass/fail rates, accuracy and empathy, all from one dashboard. For every failed test, dive into actual vs. expected responses, AI reasoning and transcripts to diagnose and correct errors faster.

Ensure reliable, brand-safe AI before every deployment

Enterprise-grade validation with built-in guardrails

Deploy AI agents with confidence by embedding automated validation and enterprise-grade controls into every stage of development. From enforcing SLAs and tone guidelines to testing real-world journeys across channels, Yellow.ai ensures your agents stay on-brand, compliant, and production-ready.
