Annotation editor
AI Does the First Pass. You Refine the Result.
The editor is where a dataset becomes trustworthy. Open a folder of images with their labels, step through them with the keyboard, and correct anything the first pass got wrong.
Tools built for correction, not just creation
Rectangle, polygon and pen tools share one canvas. Selecting an existing annotation lets you move it, reshape it, change its class or delete it outright.
- · Rectangle mode for detection boxes.
- · Polygon and pen modes for segmentation outlines.
- · Object class list with colours so mislabels are obvious.
- · Labelled objects panel to select and delete annotations directly.
- · Undo and redo for every edit.
- · Open and save projects so a review session can be resumed.
