  • Each has a real cost: Perplexity context window has been stealthily reduced despite prior claims of 1-million-token capacity; Replika the App Store listing confirms Replika (Luka, Inc.) is free to download with core messaging available at no cost, but premium features are gated behind in-app purchases with no price figures disclosed in the listing.
  • They diverge on capability: Perplexity covers Real-time web search, Replika covers Conversational AI.
