Inspiration
City planning decisions (parks, transit, housing, climate planning) are usually slow, fragmented, and buried in long policy documents that are hard to use. We built CityBrainz AI to change that — by letting planners ask questions in plain English and instantly get expert-level planning recommendations grounded in real city documents.
Instead of reading dozens of PDFs, users get a fast, AI-powered planning team in their browser.
