- For
- Bay Area residents tracking AI advertising in public space
- Worth noticing
- Entries distinguish neighborhood-level locations from exact intersections and warn when a photo’s publication date is not a verified capture date.
Field notes
Entries combine campaign wording with location and source details, while the map separates sightings across San Francisco, the Peninsula and SFO, and the South Bay. The page explicitly says there is no live ad feed; its Street View references are recorded imagery, and at least one entry marks the photo’s publication date as distinct from a verified sighting date.
