AI-Assisted Annotation
We integrate machine learning pre-labeling into our pipelines to accelerate throughput without sacrificing quality. Every AI-generated annotation is reviewed, corrected, and validated by trained human annotators before delivery.
- ML pre-labeling reduces turnaround time
- Human review catches edge cases and model drift
- Compatible with client-provided models
- Works with our own pre-annotation tooling
Multilingual Annotation
Native-language annotation teams for bilingual and cross-lingual projects.
- English Annotation & QA
- Chinese (Mandarin) Annotation & QA
- Bilingual Labeling Workflows
- CJK Text Processing & NER
- Cross-Lingual Quality Validation
