Auto Image Annotation Tools Best in 2021

The Best Tools For Auto Annotation Tools That You Should Know


Every few months, a new training data platform hits the market, offering new revolutionary capabilities such as quicker auto annotation toolsAnnotation tools  or increased accuracy.


It’s simple to become perplexed while attempting to select the ideal picture annotation tool for your needs.




It’s critical to optimize your data annotation procedure to ensure your model’s high performance and dependability. As a result, selecting the proper technology for your computer vision tasks is crucial.



Top paid Auto Annotation Tools


V7 (

Let me begin by noting that we will not be overtly proclaiming V7 to be the finest picture auto annotation tools available.


We won’t brag about people calling V7 the most adaptable and powerful tool for image and video annotation, or that we’re the “top training data platform.”




None of that is true.


Making such big remarks in our own piece isn’t the best place to do so.




We’d like to invite you to give V7 a try and see if we’re deserving of all the wonderful feedback we’ve received 😉


V7 is an auto annotation platform that combines dataset management, picture, and video annotation, and model training to accomplish labeling jobs automatically.

Teams may use V7 to store, manage, annotate, and automate their data annotation operations in the following areas:


The following are some of the highlights:

  • Annotation characteristics that are automatically generated without the requirement for prior training
  • Multiple models and humans in the loop phases are possible with composable workflows.
  • Large-scale data management that remains stable
  • Data labeling services that are integrated
  • Real-time collaboration and a flexible user experience
  • Annotation tools for the video that is frame-perfect

Labelbox (


Labelbox is a data platform for training that is made up of three layers that help with anything from labeling to collaboration to iteration. It was founded in 2018 and has since grown to become one of the most widely used data labeling applications.


Labelbox provides AI-assisted labeling tools, labeling automation, human labor, data management, a robust API for integration, and a Python SDK for expansion.


It supports polygon, bounding box, and line auto annotation, as well as more sophisticated labeling capabilities.


Features to look for:

  • Labeling with the help of artificial intelligence (BYO models)
  • Data labeling services that are integrated
  • Tooling for quality assurance and quality control, as well as processes for label review
  • Analysis of the performance of strong labelers
  • Tasks may be made easier with a customizable interface.
  • Free 5000 images/Custom Pro and Enterprise plans available.


Scale AI (


Scale AI is a data platform that allows huge amounts of the 3D sensor, picture, and video data to be auto annotation.


The scale provides machine learning-powered pre-labeling, an automated quality assurance system, dataset administration, document processing, and AI-assisted data annotation tools for autonomous driving, but not data processing.


This data annotation tool supports several data formats and may be used for a range of computer vision applications such as object identification, classification, and text recognition.




  • Pre-labeling with machine learning
  • Management of the Nucleus dataset
  • Gold settings in an automated QA system
  • Features of document processing
  • Data curation using a model in the loop



Superannotate (


Superannotate is an image and video annotation tool that automates and simplifies computer vision operations from start to finish.


SuperAnnotate lets you generate high-quality training datasets for a variety of computer vision tasks, such as object identification, instance, and semantic segmentation, keypoint annotation, cuboid annotation, and video tracking.


Vector annotation (boxes, polygons, lines, ellipses, keypoints, and cuboids) and pixel-wise annotation using a brush are among the techniques available.


Features to look for:

  • Labeling with the help of artificial intelligence (BYO Models)
  • Semantic segmentation with superpixels
  • Quality assurance systems of the highest level
  • Image conversion supports a variety of formats.


Price: 14-day free trial / Starter, Pro, and Enterprise plans are all customizable.

Top free auto annotation tools:




CVAT (Computer Vision Annotation Tool) is an open-source, web-based image and video auto annotation tools supported and maintained by Intel for labeling data for computer vision.


The main tasks of supervised machine learning are object recognition, picture classification, and image segmentation, which are all supported by CVAT. Boxes, polygons, polylines, and points are the four main forms of annotations available.


Features to look for:

  • Annotation that is semi-automatic
  • Shape interpolation between keyframes
  • Annotation projects and tasks are listed on the dashboard.
  • LDAP
  • Supports a wide range of automation tools, such as automated annotation and video interpolation utilizing the TensorFlow* Object Detection API.
  • It’s collaborative and web-based.
  • CVAT is simple to set up on a local network using Docker, but it must be maintained as it grows.
  • Annotation that is semi-automatic


LabelMe (


The MIT Computer Science and Artificial Intelligence Laboratory invented LabelMe, an online annotation tool. It offers a digitized picture dataset with auto annotation.


The dataset is accessible to external additions and is available for free.


Polygon, rectangle, circle, line, point, and line strip are among the six annotation types supported by Labelme. The fact that files may only be stored and exported in JSON format is one of the restrictions.


Features to look for:

  • Modification of control points
  • Removal of segments and polygons
  • There are six different sorts of annotations.
  • List of Documents


Labelimg (


An image annotation tools that uses bounding boxes to name things in pictures. Python was used to create it. Your annotations can be saved as XML files in PASCAL VOC format.


Labeling only has one annotation type in its default version: a bounding box or rectangle shape. However, a GitHub page may be used to create another shape using code.


Features to look for:

  • PASCAL VOC saves annotations as XML files.
  • It must be installed on a local level.
  • Only picture auto annotation is allowed.
