Test Stack AI Chat Assistants

Score every Stack AI chat assistant reply across 9 quality metrics, including hallucination detection, knowledge grounding, and conversation flow.

Chat Assistants

9 Quality Metrics

Score bias, hallucination, completeness, context awareness, response quality, and conversation flow on every chat turn.

RAG Grounding Checks

Confirm answers come from your connected Knowledge Base, not policy or pricing the LLM invented.

Multi-Turn Memory

Push the assistant through follow-ups and clarifications to catch where it loses the thread.

Complete Stack AI Testing Coverage

Confidence by Evaluation Volume

HIGH (100+ evaluations), MEDIUM (50-99), LOW (20-49), VERY LOW (below 20). Confidence calibrates to how many scenarios you run.

Confidence by Evaluation Volume

9 Quality Metrics on Every Response

Bias, hallucination, completeness, context awareness, response quality, flow, user satisfaction, file handling, and file accuracy, ideal for document-heavy Stack AI agents.

9 Quality Metrics on Every Response

4-Dimension Go-Live Assessment

Each run scores Functional Completeness, Quality Standards, Risk Profile, and Operational Readiness, each weighted at 25%, before you publish.

4-Dimension Go-Live Assessment

Pass/Fail Analysis Output

Pinpoint every match and discrepancy in your agent's answers and tool calls, tracked as Pass, Fail, or Partial against your criteria.

Pass/Fail Analysis Output
