Michael vs Perplexity vs Grok -- the three most talked-about AI platforms of 2026, each representing a fundamentally different philosophy about what AI should be. Perplexity says AI should search. Grok says AI should entertain. Michael says AI should understand. This comparison covers every dimension that matters.
Full disclosure: I built Michael. But this comparison is as honest as I can make it, because I genuinely believe the right choice depends on the individual. Some people should use Perplexity. Some should use Grok. Some should use Michael. And some should use all three.
