[RootX22]

A page at rootx22.github.io/groundcheck where you paste an answer and its sources and get the same report as groundcheck --json: the grounding score, each finding with its evidence, and a sentence-by-sentence view with the closest source.

• It runs the package itself in the browser through Pyodide. The Pages workflow zips groundcheck/ on every deploy, so the page cannot drift from the CLI.
• No model is called and nothing is uploaded. Share links carry the texts in the URL fragment.
• Pasted text is rendered as text, so a crafted share link cannot run script on the page. Tested with <img onerror> and <script> payloads.
• The support threshold is adjustable, with the CLI's default of 0.5.

Checked in Chromium at desktop and phone widths: no console errors and no horizontal scroll.
