Deploying and Managing Your Chatbot

When it comes to deploying your chatbot, you have a couple of options. You can either integrate it into existing platforms like websites or messaging apps or deploy it as a standalone bot.

Integrating Your Chatbot into Existing Platforms

Integrating your chatbot into these platforms can be a great idea if you already have a website or a messaging app that your users frequently visit. 

For websites, you can embed your chatbot directly on your site, allowing users to interact with it seamlessly. 

Regarding messaging apps, you can leverage messaging APIs to connect your chatbot with popular platforms like Facebook Messenger or WhatsApp. 

By integrating your chatbot into existing platforms, you can reach your audience where they already are, providing a convenient and familiar experience.

Considerations for Standalone Chatbot Deployment

On the other hand, standalone deployment is the way to go if you want your chatbot to have its dedicated presence. 

This typically involves hosting your chatbot on a server, either on your own infrastructure or cloud services.
