Our review
Pros	Shared codebooks support annotation across collaborators. Active learning helps prioritize examples for annotation. Combines scikit-learn, BERT training, topic models, and export.	Combines sampling, filtering, deduplication, review, and evaluation Supports classification, detection, and segmentation annotation Offers Python APIs, plugins, and cloud or on-premise deployment
Cons	Its primary audience is computational social scientists. The hosted CREST instance requires an account request. Self-hosting requires deployment on an organisation’s infrastructure.	Its verified annotation focus is image and video, not text workflows Multi-user controls and shared datasets are Enterprise capabilities Model-assisted labeling relies on SAM3 and LightlyTrain plugins
Our verdict	ActiveTigger is an open-source web application for collaborative corpus annotation and classification, aimed primarily at computational social scientists. Teams upload tabular datasets, define shared codebooks, and annotate text together,… Read the review →	LightlyStudio is an open-source workflow tool for computer vision teams managing image and video datasets.
