If you're looking for a chatbot that offers personalized advice and assistance in many areas, Guru is a great option. Built directly into WhatsApp, Guru uses the official ChatGPT API for a natural, conversational interface to discuss topics like self improvement, science and technology. It's available 24/7 and offers private, secure interactions. Guru is designed to respond immediately and follow up on questions, so it can be a good conversational partner for any question you might have.
Another option worth considering is the AI Chat PowerBrain Assistant & AI Chatbot. This chatbot uses GPT-4 technology for quick answers, automation and more sophisticated natural language processing. It works with multiple languages and services, and offers features like AI translation, content generation and chat history synchronization. The free plan offers limited access to its tools, so it's a good starting point to test its abilities.
Last, Chat Data offers a tool to build your own AI chatbots with your own data and models. You can integrate your own data and models, customize the interface and get analytics on how conversations are going. Chat Data offers a free plan and tiered pricing, so it's good for small or large-scale use.
