I am curious to explore other providers of generative artificial intelligence services. I am a paying subscriber to ChatGPT, but I haven’t seriously explored other alternatives yet, though I plan to do so. I fear missing things out if I ever leave OpenAI behind. I tested Perplexity, but I don’t believe in their business model. I think Claude from Anthropic seems to be the most interesting candidate. They have an iPhone and iPad app, just like OpenAI. From now on, I will systematically query both ChatGPT and Claude for my research needs and compare their performance.
