The Whole Agent vs Aero IDX
Aero IDX is a promising, genuinely AI-first newcomer — roughly a year old, around $199/mo, with about 15 MLSs live so far. The catch brokers should weigh: it has been reported to feed live MLS listing data into third-party LLMs, which runs against CRMLS/RECORE IDX rules that prohibit using MLS data to train or operate machine-learning models. The Whole Agent is AI-native too, but architected so MLS listing data is never sent to or trained on by AI models.

When Aero IDX might be the better fit
Aero is a genuinely AI-first entrant, and if you're on one of the specific MLSs they've onboarded and want to try a brand-new tool, they may be worth a look. For brokers who value their MLS agreement, an AI that never feeds MLS listing data into third-party models is the safer choice — see how we handle it on our MLS-compliant AI page.
