For a bit of historic accuracy if it ever matters for future readers:
Kagi was founded in 2019 and we have operated for years in private beta with thousands of users before public beta release this June.
Goggles were not inspired by Kagi”s lenses and I can confirm seeing the whitepaper before we got the lens feature out last year.
Kagi”s Lenses were inspired by Blekko’s “slashtags” which is probably the original “prior art” for this kind of feature.
Looks like we arrived to similar idea, but different execution. Kagi”s Lens feature is osimple to create filter for the web, that anyone can make with a few clicks plus a bunch of powerful built-in lenses like “noncommercial” or “discussions” search.
