Scout is the best tool for finding activities for your child. I built this to solve my personal pain point. Currently the best solutions are wordpress blogs where people manually aggregate this information. But human-run blogs can't possibly find every event, they don't know what my child's interests are or what's near my home, so my wife & I would spend hours just learning what we can do with our child. Scout is totally different. Our Agents intelligently crawl the web and find everything in a specific geographic region. We're staring with Seattle, where I live. Scout event has an "inclusivity" filter which lets you find events that are sensory friendly, ASL/assistive listening/captioning, LGBTQ+ & trans affirming, wheelchair accessible, etc. My favorite feature is the daily email with a curated list of events for you. This week I've gone to 2 events based on those emails alone. Please take a look and give me your feedback! demo: https://youtu.be/6wEVtp7-wV4 The link above is
