Annotate-Lab

What Annotate-Lab is

Annotate-Lab is a free web tool for creating image annotations with configured region shapes. Its workspace supports polygon regions and bounding boxes, while an example also shows a circle tool for marking areas. Model-assisted labeling is available to support the annotation workflow. When annotations are ready for use elsewhere, Annotate-Lab can export an annotated image, a mask, and annotation settings. YOLO format is also available for dataset export, giving users a structured option for machine-learning workflows. The service runs on the web and has a free plan. Its tools cover both region marking and preparation of files for later processing. Different region types let users describe image areas in more than one way, and model assistance can contribute to the labeling process. Export choices include visual results, mask data, configuration details, and YOLO-formatted annotations. Annotate-Lab does not provide team collaboration, so its listed workflow centers on individual annotation work in a browser.

Who it suits

Annotate-Lab suits people who need browser-based image region labeling with polygons or bounding boxes. It is also useful for users who want model-assisted labeling and YOLO exports without a paid plan.

Getting started

1. Open the Annotate-Lab website
2. Use the web interface to load an image
3. Choose polygon or bounding-box region annotations
4. Use model-assisted labeling if needed
5. Export the annotated image, mask, settings, or YOLO data

Verdict

Choose Annotate-Lab for free, browser-based image annotation with several region shapes and model assistance. Its export options support annotated images, masks, settings, and YOLO data. Look elsewhere if shared team collaboration is required.
