Data Annotation

High-quality, training-ready datasets for AI and ML models.

AI systems are only as good as the data they learn from. At LabelNest, we specialize in precise text, audio, and image annotation - ensuring your models are trained on structured, accurate, and scalable datasets.

What We Offer

Text Annotation

  • Named Entity Recognition (NER)

  • Sentiment and intent tagging

  • Part-of-speech tagging, tokenization

  • Relation and dependency labeling

Audio Annotation & Transcription

  • Human-grade transcription with timestamps

  • Speaker diarization (who said what)

  • Emotion and tone labeling

  • Keyword spotting and tagging

Image & Video Annotation

  • Bounding boxes, semantic segmentation

  • Instance labeling & object tracking

  • Keypoints & pose estimation

  • Frame-level video annotation

Dataset Collection

  • Multilingual text corpora

  • Domain-specific datasets (finance, healthcare, legal, etc.)​

  • Speech/audio collection across accents & environments

Our Process

  • Guideline Design - Collaborate with you to define schema, examples, and edge cases.

  • Pilot Phase - Run a small batch to calibrate quality and adjust guidelines.

  • Annotation at Scale - Deploy annotators + reviewers with role-based workflows.

  • Quality Control - Multi-pass QA, inter-annotator agreement, escalation handling.

  • Delivery - Clean datasets in your required format with documentation.

Use Cases
