Sonar Pro
For anything that changed this week. Sonar Pro reads the live web and answers with clickable sources, so you can check before you publish.
[ Overview ]
Meet Sonar Pro.
Sonar Pro is Perplexity's grounded answer engine, and it is the model to ask when the answer depends on what is true today. SEO teams, consultants and anyone who publishes for a living use it because it shows its sources.
Check a competitor's current pricing before you write the comparison page. Pull the live stats for a client blog post and get the links to cite. Find out what changed in a platform's policy last month. Ask what people are saying about a product before you pitch against it. Every answer arrives with sources you can click and verify.
Sonar Pro reads the live web, which is the thing a normal chat model cannot do. Use it for the quick sourced answer. When a question needs step-by-step reasoning over those sources, move to Sonar Reasoning Pro, and for a full written report, Sonar Deep Research. All of them come with HiggsChat on one subscription.
