How we help

Our services are designed to empower AI systems with the highest quality annotated data, ensuring that your machine learning models achieve exceptional accuracy and reliability. 

Text Annotation

Enhance your AI models with expertly labeled text. We deliver clean, structured, and insight-rich datasets.

Semantic Precision

From sentiment to intent, we capture nuances with accuracy.
Empower NLP solutions with context-aware annotations.

Image Annotation

Train computer vision models with pixel-perfect accuracy.
Bounding boxes, polygons, and keypoints—all done right.

Visual Intelligence

Our annotations drive object detection and recognition.
We ensure every image tells the right story to your model.

Video Annotation

Frame-by-frame labeling for dynamic machine learning.
Perfect for tracking movement, behavior, and activity.

Temporal Accuracy

From object tracking to event tagging, we annotate with precision.
Turn raw footage into actionable training data.

Audio Annotation

Transcribe, label, and classify sound data with clarity.
Ideal for speech recognition and acoustic AI training.

Sound Understanding

We capture tone, emotion, and intent from audio files.
Fuel your voice-AI with context-rich, quality data.

FAQs

We use a multi‑layer quality assurance process: trained annotators work with your defined guidelines, we perform peer review and lead review, we calculate inter‑annotator agreement and error rates, and you receive a quality summary with each delivery.

We support text, image, video and audio annotation, and we have experience in varied domains (e.g., healthcare, automotive, retail) so we can adapt the label schema to your industry.

We don’t use a “one‑size‑fits‑all” price. Each dataset is unique in complexity, number of classes, edge cases, required attributes, etc. We will evaluate your dataset, define the workflow, and then provide a quote (per image, per bounding box, per hour, or contract‑based) including volume discounts.

After reviewing your dataset size and complexity, we give you the expected delivery timeline, including milestones. We scale with additional annotators and/or shifts as required, while maintaining consistency via our QA pipelines.

We execute NDAs/DPAs, use secure transfer and storage protocols, restrict access to approved personnel, and support encrypted data workflows or air‑gapped environments if needed.

Yes — we include a post‑delivery review phase and will correct any annotations that don’t meet the original specification (provided the original requirements haven’t changed). We can also support ongoing refinement if your model evolves.

We recommend running a small sample/ pilot batch of annotations (often free or at minimal cost) so you can review quality and workflow fit before scaling. If your scope changes (e.g., more classes, extra attributes, more volume) we’ll revisit the workflow and provide a change‑order quote rather than silently absorb cost or delay.
