The annotation pipeline

From raw data to model-ready ground truth

One pipeline for every modality, with humans at the point where judgment matters.

The Synthetic Limit

Pure automated labeling creates compounding feedback loops of error.

Model Degradation

Self-trained models eventually plateau. Edge cases like occlusions, adverse weather in CV, or sarcasm in NLP require nuanced human judgment that machines cannot inherently deduce.

Lack of Domain Expertise

Generic crowdsourcing platforms fail miserably when tasking medical imaging or financial document extraction. High-accuracy AI requires domain-trained subject matter experts.

Human-in-the-Loop Workflow

Automated models execute the first pass; our human experts resolve the exceptions. This continuous feedback loop ensures that your AI pipeline learns from novel edge cases without corrupting its foundational weights.

  • Exception handling APIs
  • Active learning integration

Multi-Tier QA Framework

Our 99.5% quality guarantee isn't a marketing claim; it's a contractual SLA backed by a rigorous 3-tier validation process involving automated checks, consensus scoring, and physical gold-standard auditing.

  • Automated schema validation
  • Blind consensus (inter-annotator agreement)
