Limits on the Pro subscription (2026)

Main article: Perplexity throttles PRO subscribers without prior notice

In February 2026, Perplexity set limits for Pro subscribers who previously did not have any limits.

Limits on free accounts on PCs (2026)

In mid-September 2026, Perplexity introduced limits for logged-in free-account users even for the most basic searches, making Perplexity the first known LLM website to become fully useless after only few queries when not having a subscription. This limit can factually not be bypassed by simply opening a private browser-window and using Perplexity without being logged into the site, as a login-notification prohibits further interaction, hinting at the company using IP-level query-throttling. This limit strangely does not seem to apply to the Perplexity (Android) app.

Screenshot showing message a user is given after reaching somewhere between 5 and 10 queries within a 24h time-frame.
