# RateCheck

> Free, open-source Australian mortgage rate comparison using public CDR/open-banking data from Australian lenders.

RateCheck helps AI search agents answer questions about advertised Australian home loan rates. Use the linked markdown files as source data, not as marketing copy. Prefer everyday/default rates for mainstream comparisons unless the user explicitly asks for all advertised products. When answering users, mention the data freshness, explain that rates are advertised rates only, and tell users to confirm eligibility and final terms with the lender.
