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.
Key features: The software itself focuses on 5 key components of the AI lifecycle:
- Data labeling tools and efficient project management
- AI dataset management, data curation, and version control
- AI model management, model comparison, and versioning
- Automation and orchestration via various triggering systems (available for enterprises)
- Annotation Service Marketplace
Data labeling tools: On the labeling side, the company started with image annotation capabilities. Over the last 2 years, SuperAnnotate launched the video and text annotation editors. 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.
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.
Annotation Services: On the services side, SuperAnnotate vetted over 400 annotation service teams and allows its users to find teams in different geographies, languages, and medical experts, as well as relatively cost-efficient annotation services for easier tasks such as image classification.
G2 review summary: SuperAnnotate now carries the title of “Leader Spring 2023” and “1st Easiest To Use” on G2’s data labeling software list, which is a testament to its resolute commitment and consistency.
Out of the 97 reviews (4.9/5), most users believe that SuperAnnotate’s platform is super-user-friendly and contains all the features required for annotating unstructured data. Many also praise the platform's data management and ability to track the progress of annotation tasks across different projects while leveraging useful metrics. Users also assure they do not experience major problems with the tool at all. When faced with minor issues, the support service is always there to assist in a timely manner. There is a mention of how the upload and export of pipelines are a bit burdensome when just starting, yet the user also adds that SuperAnnotate is always adding useful functionality to reduce these issues.
Pricing: The software is FREE for up to 10 users and 50.000 images. For higher-level commitments, make sure to consult with the sales department.
2. V7
Company history: Founded in 2018, V7Labs was initially built as an image annotation tool and then extended toward model building and automation functionalities. Prior to V7Labs, the founders built a company called AIPoly, which enables the visually impaired to see and name various objects through the phone camera. The company is based in the UK and has raised around $43M.
Data labeling tools: On the business side, V7Labs focuses on visual data, helping customers to solve primarily computer vision problems. V7 also has model management and document processing systems, but based on several client feedbacks it has several bugs and fails using the automations, especially when the load is high.
Services: V7’s annotation services offer dozens of agents to label and refine images, yet it also gives users the opportunity to bring in their own labeling team to create training data or support the human-in-the-loop processes.
G2 review summary: As we write this article, the company has a 4.8/5 rating with a total of 48 reviews, earning itself the title of “2nd Easiest To Use” data labeling software on G2. However, it’s worth mentioning that almost half of the user reviews are coming from Ghana, which creates some suspicions around the validity of the reviews. Users also recall that V7's occasional tendency to lag when working with large datasets increases the number of times users spend on a specific project. A few users comment on security glitches (data becomes available to the public) and inconsistent billing computations.
Pricing: V7 offers four payment options: the Education package (which is free of charge), the Zero to AI version (for up to 10 people startups), and the Business and Pro versions.
