Annotation

Turn pixels into useful labels.

Pedestrians, cars, a dog, and traffic lights marked with detection boxes
Annotation, shaped around your data and delivery needs.

What we deliver

Clear labels. Useful training data.

Give each data type the structure it needs, with shared guidelines and human review built into the work.

Image Annotation

Mark the objects, regions, and details your vision model needs to learn. Annotation rules and sample review keep labels consistent across a dataset.

  • Bounding boxes, polygons, and segmentation
  • Classification, keypoints, and attributes
  • Guideline calibration and edge-case review

Video Annotation

Annotate video frames with labels that preserve movement and continuity. Define frame sampling, tracking rules, and event boundaries around your task.

  • Frame-level objects and attributes
  • Object tracking across selected frames
  • Actions, events, and temporal segments

Text Annotation

Organize documents and conversations with a clear text taxonomy. Human review helps resolve ambiguous wording and apply labels consistently.

  • Entities, intent, sentiment, and topics
  • Classification and relationship labels
  • Span rules and adjudication guidance

Audio Annotation

Label speech and non-speech audio with the timing and context your models require. Capture speaker turns, sound events, and uncertain segments clearly.

  • Speaker and turn labels
  • Word, phrase, or event timestamps
  • Sound classes and acoustic attributes

OCR Annotation

Prepare image and document labels that help OCR systems read text and understand layout. Capture text regions alongside their order and structure.

  • Text transcription and bounding regions
  • Reading order, tables, and key-value fields
  • Handwriting and low-quality scan review

3D Annotation

Structure point clouds and 3D scenes with labels suited to perception tasks. Define object classes, box conventions, and review rules for consistent spatial data.

  • 3D cuboids and object classes
  • Point-cloud segmentation and attributes
  • Coordinate, occlusion, and consistency checks

Generative AI Prompt and Response Annotation

Label prompts and generated responses against a shared rubric. Capture intent, quality, safety, and response traits so examples can support training and evaluation.

  • Prompt intent and response attributes
  • Quality, safety, and policy labels
  • Comparison judgments and rationale codes

How we work

A clear path from brief to delivery.

Requirements agreed early. Human review throughout.

  1. 01

    Define labels

    Agree on the taxonomy, attributes, edge cases, and export schema.

  2. 02

    Calibrate a sample

    Review a small sample together to align labeling decisions.

  3. 03

    Annotate & review

    Apply the guidelines and resolve uncertain examples during review.

  4. 04

    Export data

    Validate label structure and package files for your pipeline.
