Human-led AI evaluation and data annotation designed to improve model quality, safety, and real-world performance

AnnotaX provides human-led AI evaluation and data annotation services designed to improve model quality, safety, and real-world performance.
All services are delivered by a distributed expert team, led by a dedicated technical lead.

LLM Evaluation & Quality Assurance

We help AI teams systematically evaluate large language model outputs to identify and reduce:

  • Hallucinations and factual errors
  • Bias and unsafe responses
  • Inconsistency across prompts or languages
  • Quality degradation at scale

How we work

  • Structured human review frameworks
  • Multi-reviewer scoring for consistency
  • Clear, actionable feedback for model teams

Best for

  • Model validation before deployment
  • Ongoing quality monitoring
  • Safety and alignment testing

Multilingual Data Annotation & Review

Our team supports multilingual annotation and review to ensure datasets reflect linguistic accuracy and cultural context, not just literal translation.

Supported work includes

  • Text classification and labeling
  • Prompt–response evaluation
  • Translation review and consistency checks
  • Multilingual dataset validation

Why it matters
Poor multilingual data leads to unreliable global AI systems. We help teams avoid that.

Mental Health & Safety-Critical AI Review

For AI systems used in sensitive or high-risk domains, human judgment is essential.

We support evaluation and annotation workflows for:

  • Mental health and wellbeing applications
  • Safety-sensitive conversational AI
  • Content requiring careful ethical review

Our approach emphasizes:

  • Reviewer training
  • Clear guidelines
  • Conservative quality thresholds

Our Delivery Model

Each project is delivered using a team-based structure:

  • One technical lead responsible for quality and communication
  • Trained reviewers selected based on language and domain needs
  • Scalable capacity depending on project size and timeline

Clients interact with one point of contact, while benefiting from team execution.

Engagement Options

Most engagements begin with a short pilot or evaluation sprint to confirm quality and workflow fit.

Typical formats include:

  • 2–4 week evaluation pilots
  • Fixed-scope annotation sprints
  • Ongoing monthly support

We adapt scope and capacity based on results.
