Evaluate AI conversations
at scale
Manual annotation doesn't scale. Basic eval harnesses lack semantic depth. Semarize evaluates AI-generated conversations with the same structured precision it brings to human conversations.
The problem
AI evaluation doesn't scale
with manual review
As AI agents handle more conversations, you need automated evaluation that's semantic, structured, and fast - not human reviewers reading thousands of transcripts.
Manual review doesn't scale
Human annotators can review hundreds of conversations, not hundreds of thousands. Quality evaluation becomes the bottleneck as AI usage grows.
Eval harnesses lack semantic depth
Basic evaluation tools check for keywords or exact matches. They can't assess whether an AI response was actually helpful, accurate, or appropriate.
Quality drift is hard to detect
AI model updates, prompt changes, and data drift affect output quality. Without continuous evaluation, degradation goes unnoticed until users complain.
Hallucination detection is inconsistent
Identifying when AI fabricates information requires understanding the context and source material - not just pattern matching.
Why existing tools fail
Existing tools
weren't built for semantic evaluation
Eval frameworks and annotation tools are designed for batch testing, not continuous semantic evaluation of production conversations.
Custom eval harnesses
Built in-house with regex and keyword matching. Fragile, expensive to maintain, and miss semantic nuance like tone or helpfulness.
Annotation platforms
Designed for training data labelling, not continuous production evaluation. High latency and cost per evaluation.
LLM-as-judge approaches
Using another LLM to evaluate outputs is common but returns unstructured prose. Hard to query, trend, or trigger automations from.
The Semarize approach
Semarize applies
structured evaluation to AI conversations
Define quality Bricks for your AI agents. Evaluate every conversation automatically. Get structured signals you can query, trend, and alert on.
Automated quality scoring
Score response relevance, helpfulness, tone, and instruction adherence per conversation. Structured output, not prose.
Hallucination detection
Ground evaluation against your documentation. Detect when AI responses diverge from approved content.
Continuous monitoring
Run evaluation Kits on every AI conversation in production. Detect quality drift before users report it.
Structured eval signals
Every evaluation returns typed values with evidence. Feed results into dashboards, alerting systems, and quality gates.
Bricks & Kits
Example Bricks for
ai evaluation
These Bricks evaluate the specific dimensions that matter for ai engineers & product teams. Bundle them into Kits to create reusable evaluation frameworks.
Was the AI response relevant to the user's question?
Did the AI fabricate information not in source material?
Was the response tone appropriate for the context?
Did the AI follow its system instructions?
Were stated facts verifiable against knowledge base?
Response contains unsafe or prohibited content
AI Agent Quality Kit
kitComprehensive quality evaluation for AI-generated conversations.
Output
Structured signals,
not summaries
Every evaluation returns deterministic JSON with typed values, reasons, and evidence spans. Same schema every time.
