Not sure how useful it is. There's a requirement for the actual bill summary to be accurate - this isn't the US where you can submit unrelated amendments to arbitrary legislation.
Few people are aware of what bills are put before parliament, much less of their impact. Most of us don't have time to read every bill; but seeing a snapshot like this can help us decide which ones we want to look into more closely.
But why trust a potential AI hallucination when you can get the actual data from They Work For You.
What data though? The website doesn't show me a summary assessment, like what the AI one does.
