The real-time physical layer
for America’s major metros.
Dayplay is the real-time physical intelligence engine for major metropolitan areas nationwide. We verify real-time places, live events, and walkable itineraries — live in every major US metro, with the San Francisco Bay Area — San Francisco, Oakland, and Berkeley across 35 verified hubs — as our flagship proof point. Every live market is grounded in verified neighborhood centroids and zero fabricated venues.
Why we exist
AI assistants answer “what should we do tonight?” with confidence — and sometimes invent a bar that closed in 2023, misstate the hours, or send you across the bay for a “walkable” evening. That’s not a small bug. It’s a trust problem in how models meet the physical world.
Dayplay fixes the input, not the prompt: a deterministic, spatially-verified dataset of places and live events, served to humans through the Dayplay app and to machines through our official MCP server. When nothing verified exists, we say so — the Anti-Drift Guarantee means we never fabricate venues, events, dates, or hours.
What we build
The Dayplay app turns verified local answers into one-tap plans. Join the waitlist at dayplay.io/waitlist.
An official Model Context Protocol server — one remote URL, no API key. Docs at dayplay.io/mcp.
35 verified neighborhood guides in our flagship market, with new metros added as they pass verification — see one live.
How we work
Dayplay is built by a small, scrappy team of passionate builders based in San Francisco. Our proprietary engine reconciles the full local signal layer — venue calendars, permits, box offices, and neighborhood happenings — into one deterministic dataset: spatially checked, catalog verified twice daily, guides rebuilt every 30 minutes, and grounded per market. We verify metro by metro on purpose: a city only goes live once its places and events are fully verified, because unverified coverage is worse than no coverage.
The company is Dayplay LLC, headquartered in San Francisco.
How fresh our data is
Freshness is a product feature, not a footnote. Dayplay runs a published verification cadence and states it plainly — so humans and AI agents both know exactly how current the dataset is before they rely on it.
Full event + venue catalog re-ingested daily at 00:00 UTC, with a second daily event sync at 06:00 UTC.
“Happening now” and decision feeds are computed at request time against the current clock — never a cached batch.
Each of the 35 neighborhood guides is regenerated on a 30-minute interval so date-sensitive events stay current.
Live coverage is resolved per request against the verified centroid list; a market that isn't live yet returns an honest zero, never fabricated data.
An automated identity/dedupe sweep runs weekly to merge duplicate venue and event fingerprints.
Cadence facts from the production pipeline — full catalog ingest daily at 00:00 UTC, event sync daily at 06:00 UTC, guides rebuilt every 30 minutes. We publish the schedule we actually run.
