Perplexity AI is the most reliable chatbot for daily tasks, according to a recent assessment. The app provides false information only 13% of the time compared to 22% industry average.

This comes from a May 2026 study by Legal Guardian Digital, an attorney SEO company, who examined popular AI chatbots to find which ones workers can trust most. The report measured how often each chatbot gives false information, tracked customer satisfaction ratings, and monitored how consistently they return responses.

The study also looked at uptime rates, showing how often each service stays available without crashing. These factors were combined into reliability scores, with chatbots that make fewer mistakes and stay online more regularly ranking higher.
