PyDataLabs provides end-to-end data annotation services across all modalities. Whether you’re
building computer vision models, training NLP algorithms, or fine-tuning large language models, we
deliver the precision-labeled data you need to succeed.
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.
Transform unstructured text into training data that powers intelligent language models, chatbots, and
content understanding systems.
Identify and classify people, organizations, locations, dates,
and custom entities in text
Label text with emotional tone and opinion classification for customer
feedback analysis
Categorize documents, emails, reviews, and social media content into
predefined classes
RLHF (Reinforcement Learning from Human Feedback) for model finetuning and alignment
Flag inappropriate, harmful, or policy-violating content
Understand user intentions for chatbot and virtual assistant training
Pixel-perfect labeling that trains computer vision models to see, understand, and interact with the
visual world accurately.
Rectangular boxes for object detection and localization
Precise outlining of irregular shapes and objects
Pixel-level classification for scene understanding
Identify specific points for pose estimation and facial landmarks
Volumetric labeling for autonomous vehicle perception
Categorize entire images into predefined classes
Frame-accurate tracking and temporal labeling that enables AI to understand movement, actions, and
events in video data.
Follow objects across frames with unique IDs for continuity
Label human activities and behaviors in video sequences
Break videos into meaningful segments
Categorize video content by type or theme
Track multiple entities simultaneously
Time-stamped labels for video sequences
Precise transcription and acoustic labeling that teaches AI to hear, understand, and respond to sound.
Accurate conversion of spoken words to text with timestamps
Identify and separate different speakers in conversations
Detect emotional states from voice tone and prosody
Recognize and tag different languages in audio
Categorize sounds by type (music, speech, noise)
Evaluate and tag audio characteristics
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.
