If you want a chatbot you can trust to get the straight scoop on Islam, Salam Chat is a good option. This AI chatbot has been trained and curated by Islamic scholars and includes inline citations from the Quran and Hadith so you can check the chatbot's answers. It's also got a halal filter to keep it from answering questions outside the realm of Islam, so it's good for kids. It's open-source and run by volunteers, so anyone can contribute to the project and help improve the model.
Another alternative is Pocket Hansei, which acts as a personal assistant by connecting you to vetted sources of information like books and research papers. It's not specifically geared for Islamic information, but it offers real-time answers to a broad range of questions using OpenAI models like ChatGPT. The service offers different pricing levels and protects your privacy with strong encryption and secure deletion of data.
