I use ChatGPT for Brainstorming, discussions, random questions , and even sometimes play a game with it . but it feels irritating to have emojis when I need a math problem to be solved, So that I used Gemini as Math solver , problem solver for my academics . As Gemini's responses are mostly plain , I can easily checkout that answers , Also Gemini struggles at remembering and in long conversations.. Claude , I use it rare because of free usuage limit , Also Claude generates cool responses with tables , it can even solve my problem with circuits , by using circuit diagram, I still not used Perplexity , but I got some idea it is helpful in research purposes,. Bonus: I use Consensus to get research papers. Turbo ai to generate summary of YT videos including quizzes, I tried Notebook LM , but its quality decreases as size and amount of our input files increases.
