PyWry: PyWry is a cross-platform rendering engine and desktop UI toolkit for Python with one API and three output targets: a native window through PyTauri, a Jupyter widget, and a browser tab served by FastAPI. It requires Python 3.10 to 3.14.; grainulator: Grainulator is a research tool that runs multi-pass investigations to answer questions with typed claims, tension detection, and confidence scoring. It compiles evidence from multiple angles and provides a graded answer in under 60 seconds.
