Perplexity's "Incognito Mode" is a "sham," lawsuit says: why this signal is getting harder to ignore

Perplexity’s AI search engine encourages users to go deeper with their prompts by engaging in chat sessions that a lawsuit has alleged are often shared in their entirety with Google and Meta without users’ knowledge or consent. “This happened to every user regardless of whether or not they signed up for a Perplexity account,” the lawsuit alleged, while stressing that “enormous volumes of sensitive information from both subscribed and non-subscribed users” are shared. This piece sits on 1 source layers, but the real value is showing why the story should not be skimmed past too quickly.

Perplexity’s AI search engine encourages users to go deeper with their prompts by engaging in chat sessions that a lawsuit has alleged are often shared in their entirety with Google and Meta without users’ knowledge or consent. “This happened to every user regardless of whether or not they signed up for a Perplexity account,” the lawsuit alleged, while stressing that “enormous volumes of sensitive information from both subscribed and non-subscribed users” are shared. Disturbingly, the lawsuit alleged, chats are also shared with personally identifiable information (PII), even when users who want to stay anonymous opt to use Perplexity’s “Incognito Mode.” That mode, the lawsuit charged, is a “sham.”. Ars Technica is the main source layer for now, and the rest should be read as a signal that is still widening. The useful angle sits in the effect on user behavior, revenue flow, or how platforms compete for attention on screen.

The details worth keeping

Disturbingly, the lawsuit alleged, chats are also shared with personally identifiable information (PII), even when users who want to stay anonymous opt to use Perplexity’s “Incognito Mode.” That mode, the lawsuit charged, is a “sham.”. The useful angle sits in the effect on user behavior, revenue flow, or how platforms compete for attention on screen.

Why this matters most

The signal is strong enough to deserve attention, but it still needs to be read as something developing rather than fully settled. With 1 source layers on the table, the part worth reading most closely is where firm facts meet the market's early reaction. “‘Incognito’ mode does nothing to protect users from having their conversations shared with Meta and Google,” the complaint said.

What to watch next

Patrick Tech Media will keep checking rollout speed, user reaction, and how Ars Technica update the next pieces.
