Are there no free sources for building chatbots?

The assertion that there are free sources for building chatbots is indeed correct. There are numerous platforms and tools available that offer free options for users who wish to create chatbots. These resources can range from open-source frameworks like Rasa and Botpress to cloud-based services that provide free tiers, such as Google's Dialogflow and Microsoft's Bot Framework.

These platforms enable developers to build basic chatbot functionalities without any financial investment, making it accessible for individuals and small businesses. While there might be limitations in terms of features, usage quotas, or access to advanced functionalities in the free versions, the core capabilities necessary to create and deploy a chatbot are often provided at no cost.

Understanding that free resources are available emphasizes the accessibility of technology for learning and development purposes in the field of artificial intelligence and natural language processing. This is important for students and practitioners who are exploring AI applications and want to experiment without incurring costs.
