  We present factgenie: a framework for annotating and visualizing word spans
in textual model outputs. Annotations can capture various span-based phenomena
such as semantic inaccuracies or irrelevant text. With factgenie, the
annotations can be collected both from human crowdworkers and large language
models. Our framework consists of a web interface for data visualization and
gathering text annotations, powered by an easily extensible codebase.
