Here are two alternatives to ChatGPT:
Perplexity AI is an AI-powered search engine and chatbot. In my tests, Perplexity produced quick and useful responses. It uses a fully up-to-date dataset powered by OpenAI’s GPT technology. It’s freely available on the web and as an app for iPhone.
HuggingChat is an open-source AI chatbot. It was developed by Hugging Face, an AI company founded in 2016.
HuggingChat is a generative AI tool that can create text like summaries, essays, letters, emails, and song lyrics. It can also debug and write code, create Excel formulas, and answer general questions.
