SeatPop helps parents in Ottawa find activities that fit everyone in the family, free or paid. You pick each person by age group (never names or birth dates) and get picks per person plus an "Everyone together" row. Every price, age and date shown is backed by a verbatim quote from the official listing, with a link to it, and SeatPop emails you before registration opens (an hour before for City courses with a published date, otherwise the day before). It shows what's coming next, not live seat counts, and never takes bookings itself.

How it works: the AI proposes and a verifier disposes. Any value a model extracts must match the exact words on the page or it is dropped. Age, budget, distance and time are hard rules applied first in the database, so the model can only reorder and explain candidates that already passed. If the model is unavailable, users still get a sensible list. Privacy is built in: age bands only, typed family text is redacted and discarded, and the crawler respects robots.txt and never bypasses a block.

Measured results: on 60 hand-labeled real listings, zero false "free" and zero wrong prices on three models. In a ranking eval of 20 synthetic households, Muse Spark reranking scored 0.875 NDCG@10 versus 0.738 for date order, with zero constraint violations (graded by Muse Wonder, labeled model-graded).
