Machine Learning (ML) is becoming increasingly popular and is being adopted in real-life AI applications across different industries. Creating a real-world AI application often requires extensive work with unstructured data. In fact, ML engineers and data scientists spend more than 80% of their time on data preparation and labeling and only a fraction of their time on the so-called fun stuff: reading research papers, training models, trying new architectures, tuning hyperparameters, deploying, monitoring, etc.
Since ML engineers are spending such a huge portion of their time on structuring, labeling, versioning, and debugging datasets to become AI-ready training data (aka SuperData), data labeling toolsets have become essential for building scalable AI applications. However, data labeling tools or simple data labeling editors are far away from covering all the growing needs of anyone's complex ML pipeline.
We identified 6 essential components that make data labeling tools a compelling solution for building modern AI pipelines. Namely, annotation software, AI data management and curation, integrations and security, project and quality management, and automation.
Therefore, this article is neither about simple data labeling tools using open-source software such as label studio, cvat, labelme, nor is it about specific functionalities within labeling editors such as bounding boxes, polygons, text labeling, etc.
We will cover various types of data labeling companies, along with their history and functionalities, detailed feature sets, additional AI pipeline-oriented components, and much more. We will rely on one of the most reliable software ranking marketplaces, G2, where data labeling is a separate software category within various AI software. As we indicated above, for each company/solution, we will cover the following:
- Annotation software (image annotation, video annotation, text annotation, etc.)
- AI Data Management and curation (active learning, query system, smart sampling, subset selection, data versioning, etc.)
- Integrations and security (Storage integrations, model inference API or model training integrations, etc.)
- MLOps and Automation (SDK, webhooks, orchestrations, AI-enabled labeling, model management, etc.)
- Project and quality management (Team/role management, annotation project management, and performance tracking)
- Integrated annotation services
We will be updating this article quarterly and tracking all the position changes, feature releases, large news, and announcements.
1. SuperAnnotate
Ranked as the best data labeling platform in G2, SuperAnnotate builds an end-to-end data solution with an integrated service marketplace, where they help their customers to find the right annotation team within the preferred geographic location and proficiency. The labeling teams are directly integrated into SuperAnnotate's platform and managed by their professional project managers which is reported to be one of their key strengths. The company also provides data on its platform with various labeling tools without annotation services.
Company history: Started as a Ph.D. research, SuperAnnotate was founded in 2018, primarily as an image annotation tool for semantic segmentation, but quickly gained momentum and extended into other areas of ML pipeline development. SuperAnnotate raised about $22M from investors such as P9 and Base10.

Earlier in 2022, SuperAnnotate's platform evolved into LiDAR and audio labeling. Fasting forward, they just introduced more targeted labeling data formats, such as native PDF, DICOM, etc. 2023 was remarkable for SuperAnnotate's large language models (LLMs) playground and use cases, as well as LLM fine-tuning.
LLMs: SuperAnnotate recently released its LLM playground where users can try ready-made templates for their LLM and GenAI use cases, such as supervised fine-tuning, chat rating, RLHF for image generation, model comparison, GPT fine-tuning, and video captioning. Users can also create a custom template for their specific use case by clicking on the templates.
MLOps: While covering different data formats, it is also important to cover other MLOps capabilities, which makes such annotation tooling companies more compelling within the entire AI lifecycle. On that end, SuperAnnotate’s capabilities become very attractive for any startup or enterprise users. More particularly, easy project management, data curation, data versioning, model management, automation, and complete SDK allow customers to automate incredibly complex AI pipelines (as reviews confirm).
Security: SuperAnnotate also offers multiple levels of data security, allowing users to store their datasets on their premises or in SuperAnnotate’s encrypted S3 buckets. The company owns several certifications, including SOC2 Type II on the software side and ISO 27001, GDPR, and HIPPA compliance.

The data labeling solution does not exist anymore, despite being #25 on G2.
27. TrainingData.io
Company history: TrainingData.io, founded in 2019 by a former Netflix employee, is a tool that specializes in medical imagery annotation, though it's versatile enough for other uses as well. Based in Palo Alto, the platform was developed in close collaboration with early clients to address specific annotation needs effectively. It stands out for its unique ability to annotate DICOM imagery and its support for various annotation formats.
Data labeling tools: The platform supports vector annotations (like boxes and polygons) and pixel-wise annotation. Unique features include superpixel segmentation, brushes of different shapes, magnifiers, intuitive polygon sculpting, and settings to prevent invalid annotations. The tool also stands out for its ability to annotate DICOM imagery and supports standard JSON annotation formats and PNG masks. Additionally, it offers pre-labeling using medical imagery models and tools for video annotation and point cloud annotation development.
Security: TrainingData.io emphasizes data security by offering on-premise installation using Docker, catering to the need for robust data protection, especially for sensitive medical imagery.
G2 user summary: TrainingData.io is appreciated for its large pool of qualified annotators and various annotation tools, helping businesses grow. However, the platform's speed with specific tools and features is noted as slow, and some advanced features are limited to paid plans. Users praise the data security and privacy controls and their flexibility in integrating multiple software and AI tools. The platform, while user-friendly, sometimes experiences slowdowns and downtime, particularly when importing large datasets. Some users consider the service to be high, suggesting a need for more affordable options or a lite version for startups.
Pricing: The company offers a free version, allowing up to 200 images per year with up to five collaborators. For more extensive needs, Pro ($10/mo first user, $10/mo additional user), Radiology ($50/mo first user, $50/mo additional user), and Enterprise versions are offered.
28. Ango Hub
