# ANNOTATIONS

- [Annotation Workbench](https://docs.unitlab.ai/documentation/annotations/annotation-workbench.md): Understand the shared shell, item state, controls, and navigation.
- [Image Annotation](https://docs.unitlab.ai/documentation/annotations/image-annotation.md): Create boxes, polygons, masks, cuboids, landmarks, properties, and relations on still images with AI-assisted precision.
- [Video Annotation](https://docs.unitlab.ai/documentation/annotations/video-annotation.md): Create frame-accurate object tracks, temporal events, dynamic properties, and synchronized video annotations at scale.
- [Text Annotation](https://docs.unitlab.ai/documentation/annotations/text-annotation.md): Create entities, nested spans, classifications, relations, and structured properties for NLP and LLM datasets.
- [Document & PDF Annotation](https://docs.unitlab.ai/documentation/annotations/document-and-pdf-annotation.md): Annotate native PDF text, images, tables, regions, pages, relations, and document properties without losing document context.
- [Audio Annotation](https://docs.unitlab.ai/documentation/annotations/audio-annotation.md): Label temporal events, speakers, transcripts, classifications, properties, and relations on synchronized waveform and spectrogram views.
- [Medical Annotation](https://docs.unitlab.ai/documentation/annotations/medical-annotation.md): Annotate DICOM and medical imaging with synchronized multiplanar views, clinical ontologies, timelines, tracking, and AI-assisted segmentation.
- [Pathology Annotation](https://docs.unitlab.ai/documentation/annotations/pathology-annotation.md): Annotate whole-slide images with deep zoom, tissue and cellular labels, pathology ontologies, AI assistance, and expert review.
- [Geospatial Annotation](https://docs.unitlab.ai/documentation/annotations/geospatial-annotation.md): Annotate satellite, aerial, and large-raster imagery with deep zoom, spatial coordinates, structured ontologies, and AI-assisted segmentation.
