How do I pick which one I should use?

Thanks for the link, I need to find some good youtube videos that's beginner friendly as well.

Certainly, there are several resources you can use to build your own AI bot.

1. To understand the basics, courses offered on platforms like Coursera, Udacity, and edX can be of tremendous help. These sites offer comprehensive courses on AI that can give you a good foundation.

2. For in-depth knowledge and research papers, visit sites like arXiv.org and its AI section arXiv:cs.AI.

3. TensorFlow and PyTorch are two leading AI libraries that offer a set of tools to build and train AI models. They both have extensive documentation and a vibrant community where you can ask questions and get support.

4. Google's AI Hub is a one-stop destination for finding various types of AI models.

5. GitHub is a goldmine for communities, codes, libraries, and projects related to AI development.

6. Join communities like r/MachineLearning on Reddit or follow AI tags on Stack Overflow and Medium for blogs, code snippets, expert advice, discussions, and more.

7. For chatbots, specifically, Dialogflow (formerly API.ai), a development suite for creating conversational interfaces, is handy. Similarly, Microsoft Bot Framework is a robust platform for constructing bots.

8. Websites like Towards Data Science and Analytics Vidhya offer enlightening blogs and articles related to AI and chatbot development.

9. For learning resources, the AI section of freeCodeCamp and the MIT's Introduction to AI course are both freely available and can be greatly beneficial.

Remember, building an AI bot involves coding, knowledge about machine learning algorithms, and understanding of natural language processing, among other things. Don't rush, take one step at a time, and happy learning!
