Our verdict

This extension layers ChatGPT analysis on top of the Hogangnono real estate site, summarizing apartment transaction volumes, average prices by floor tier, and Seoul-wide regional transaction trends, plus a chat window for follow-up questions. It filters apartment reviews down to the useful ones by category rather than dumping every comment on you. The developer built it as a personal side project and states outright that it carries no official authority, so it works best as a reference check rather than a sole source for a buying decision.
