5 Best Paid Image Annotation Tools

1. SuperAnnotate

This paid platform can be used for video and image annotation. With this, you can gather datasets to improve computer vision functions, such as semantic segmentation, cuboid annotation, video tracking, keypoint annotation, and object detection.

It has helpful management features, including analytics, filtering, and tags, where you can mark your progress. SuperAnnotate also offers vector annotations and pixel-wise annotations.

Service Rates: Free 14-day trial. For the rates of Custom Starter, Pro, and Enterprise plans, you may talk to their sales team.

2. Supervise.ly

This platform offers all-in-one labeling solutions. It has a bank of deep learning models that you can train and test. What makes it stand out among the others is that, aside from its advanced annotation interface, you can also make use of the whole process of computer vision.

Service Rates: Free 100 images in community edition. For other paid services, you may request a quote.

3. Labelbox

Labelbox is a web-based platform where the creators aim to help users thrive with their AI projects. They offer image annotation labeling techniques, such as lines, boxes, and polygons. Additionally, it has great project management methods, such as monitoring performance, and quality control, to name a few.

Service Rates: Free for 5,000 images. You may contact their sales team for the Pro and Enterprise service rates.

4. V7

Another best on our list is V7—an automated annotation platform. It offers dataset management, image and video annotation, and autoML model training to ensure quality and accurate image annotation output. Add to that, it also supports unique file types, such as ultra-high-resolution, multi-spectral, microscopy formats, and PDF.

Service Rates: Free 14-day trial / from $150

5. Dataloop

It’s considered as a one-stop-shop for annotation solutions, including image annotation tools. It can accommodate multiple data types. You can also maximize its model-assisted labeling, advanced team workflows with a streamlined data indexing and querying system, and video support features.

Service Rates: They offer free trial, but you can also avail their Custom Enterprise plans.

5 Best Free Image Annotation Tools

1. Computer Vision Annotation Tool (CVAT)

CVAT is considered one of the most popular image annotation tools on the internet. This tool is good for image and video annotation. Not to mention, it performs basic-to-advanced tasks such as bounding boxes, keypoint annotation, polygonal, and semantic segmentation.

It’s easy to navigate, so if you’re a beginner in this field, you might want to start with this tool. However, CVAT may not be compatible with other browsers and its functionality needs improvement.

2. MakeSense.AI

If you want an image annotation tool that’s free and secure, MakeSense.AI is a good choice. This tool doesn’t store your images and other info, so you don’t need to worry that they will be misdirected or sent elsewhere.

You don’t need to install anything because you can maximize its features online. It can perform multiple label types such as rects, lines, points, and polygons. Also, it supports different file formats: YOLO, VOC, XML, VGG, JSON, and CSV.

3. VoTT

Developed by Microsoft, the Visual Object Tagging Tool (VoTT) is an image annotation tool that aims to deliver a free, downloadable application. It’s compatible with Windows and MacOS.

In addition, it supports different extraction formats, such as Azure Custom Vision Service, CSV, CNTK, Pascal VOC, Tensorflow Records, and VoTT JSON.

One of its highlights is that it also offers active learning with features such as Predict Tag and Auto Detect. That’s a bonus because you can also use that for video annotation. However, it lacks types of annotation as it’s limited to rectangles and polygons.

4. LabelMe

Next on our list is LabelMe. This free image annotation tool was created by the MIT Computer Science and Artificial Intelligence Laboratory. The tool supports extraction formats such as polygon, rectangle, circle, line, point, and line strip.

With LabelMe, you can remove segments and polygons and modify points. It also has other features, such as File List, which enables you to see what you missed by marking the images you annotated. There’s a catch, though: you can only save and extract the file in JSON format.
