Apple Intelligence on call
With Plus, on Apple Intelligence-capable hardware, RegBrief uses Apple Foundation Models on-device:
• Plain-English RegBriefs — every section gets a plain-English RegBrief, plus tap any subsection for a focused brief on just that part of a long rule
• AI-enhanced search — results re-rank to surface the section that actually answers your question
• Selection RegBriefs — highlight any passage and get a plain-English explanation in place
On-device Apple Intelligence features run entirely on your device. The regulation text and the generated RegBrief never leave your phone.
