Tip: The Reasons for Choosing a Specific AI Chatbot

Specific Knowledge: You need to be specific while choosing a chatbot because they are trained on a specific set of data. For instance, if you want to get clinical advice, you won’t be using ChatGPT as it is not trained for that. Every chatbot has a capability and area of service.

User Experience: A chatbot can understand your question or query. If it aligns with your needs, you’ll have a great user experience. For instance, ChatGPT can’t handle personal finance like Celo.

Accuracy results: Specific chatbots are more accurate because they have more information related to the subject. For instance, a content-writing chatbot can produce human-like and better content than other chatbots. Over time, the accuracy of chatbots has improved. Some chatbots also offer sources so that you can verify.

Technical Considerations: Chatbots improve over time, and they are trained on more data. You have to consider the scalability, future growth, upcoming features, and other things in mind. They improve in a specific domain and offer similar features.


Chatbots can assist you in different areas of life, whether it be education, health, content creation, finance, etc. These are like your personal assistants who never get tired, bored, or irritated. You can freely ask any question and get relevant answers. They are fast and accurate, and over time, they are getting better. We have shared the best free AI chatbots you can use in 2024.
