Hi all, I'm sharing Jupycheck, an open source web tool that detects accessibility issues in Jupyter Notebooks that are either uploaded or from a GitHub repository. It also lets you remediate accessibility issues by launching the notebooks in a JupyterLite environment with our interactive Lab extension installed.

The tool is powered by jupyterlab-a11y-checker, an accessibility engine/extension that our student team has been working on for over a year at UC Berkeley. We believe accessibility should be a first-class concern in the notebook ecosystem, and we hope our tools can help raise awareness and make notebooks more accessible across the community.

Support us on GitHub if you find the tool useful!
