Perplexity AI's new feature lets users fact-check forwarded WhatsApp messages. "You can now forward any WhatsApp message to Perplexity and get it fact-checked instantly...It's super useful when WhatsApp groups are filled with a ton of forwarded messages which could be misleading," Perplexity's CEO Aravind Srinivas said. Perlexity's WhatsApp bot temporarily went offline following a surge in demand.
