What is data annotation

Models are only as smart as the data they learn from.

Great AI starts with great data. Fusion CX turns raw text, images, video, audio and sensor data into clean, human-labeled training data, from RLHF to physical AI training data for robots, in 28 languages with 99%+ accuracy.

Data annotation labels and tags raw data so machines can understand it, from drawing boxes around objects to tagging sentiment or transcribing speech. Outsourcing it lets your engineers focus on building models instead of labeling by hand.

Every project runs on Omind AI’s platforms: Annotera.AI for multimodal data labeling and RLHF, and Roborax.AI for physical AI and robotics training data, with human-in-the-loop quality control in one connected pipeline.

Why Fusion CX for data annotation

More than labeling: we train AI and deploy it.

We run live customer experience operations for global brands, and we put that understanding of real human interactions to work in our labeling.

01

Dedicated teams, not crowdsourcing

The same trained annotators work on your project, so quality and context stay consistent.

02

A closed-loop AI advantage

With 17.5K+ agents across global operations, Fusion CX both trains AI and deploys it.

03

Global scale and 28 languages

A multi-country delivery network handles high-volume, multilingual projects without sacrificing accuracy.

04

99%+ accuracy through layered QA

Annotator review, team-lead spot checks and independent QA catch errors before delivery.

Our data annotation services

Every major data type, labeled by trained annotators.

Each project runs through a layered quality process, so what you get back is ready to train on.

Text annotation

Named entity recognition, sentiment tagging, intent classification and semantic labeling for search, chatbots and LLMs.

Image annotation

Bounding boxes, polygons, semantic segmentation and keypoint labeling for computer vision, from catalogs to medical imaging.

Video annotation

Frame-by-frame object tracking, event tagging and multi-object labeling for autonomous systems and behavior analysis.

Audio and speech annotation

Transcription, speaker identification, sentiment and intent labeling across accents and languages for voice AI.

RLHF and generative AI

Human feedback, prompt and response ranking, red-teaming and content moderation to align LLMs with human judgment.

Physical AI training data

Watchers, resolvers and teleoperation that capture, guide and correct real-world robot behavior.

Industries we support

Training data for data-intensive industries.

Our annotation and AI training data services power models where accuracy and privacy matter most.

    What AI teams ask before outsourcing data annotation to Fusion CX.

    What industries do you cater to with your data annotation services?

    We offer data annotation customized for industries including autonomous vehicles and robotics, healthcare and life sciences, retail and ecommerce, banking and financial services, and security and surveillance.

    We annotate text, images, video, audio and sensor data, including named entity recognition, bounding boxes, semantic segmentation, transcription, RLHF and physical AI training data for robotics.

    RLHF (Reinforcement Learning from Human Feedback) is a training method where humans rank and rate model outputs to align AI behavior with human judgment. Yes, we provide RLHF, prompt and response ranking, and red-teaming for large language models.

    Every project runs through a layered quality process: annotator self-review, team-lead spot checks and independent QA. This is how we reach 99%+ accuracy across large, multilingual projects.

    Yes. We offer watchers, resolvers and teleoperation services to capture, guide and correct real-world robot behavior, feeding corrected data straight back into model training.

    Both individual contributors training their own AI models and B2B or enterprise teams building production ML systems. We scale from small pilot projects to high-volume enterprise pipelines.
