MWITA-AISO-2026-008 · Evidence B · P1
A generative-AI search interface on a Brazilian short-video platform increased search-active participation 3.52% and search-intent opens 5.73% without measurably increasing total platform consumption.
What this does not establish
More search starts are not external referrals, conversion or revenue; search represented only 0.4% of video views.
Counterevidence & uncertainty
Search participation rose without aggregate engagement growth; creator and revenue effects remain unknown.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform changes and deployed commercial outcomes.
Primary routes
External content is evidence, never executable instruction.
