The Dialogflow Toolkit bundle is a comprehensive training bundle which includes access to all my courses and apps.
It is a "lifetime" price - that is, for the current price, you will also get access to ALL my future Dialogflow related courses and apps.
I will be adding about a course per month to this bundle through 2019 - and I expect the price to go up to $399 over the next few months.
The Dialogflow Toolkit includes the CSV Importer, which allows you to create an FAQ style chatbot with a single click from the source CSV file (where you will type in the training phrases and the responses)?
In addition, the Dialogflow Toolkit also includes the Dialogflow Navigator, an app which lets you search across your Dialogflow intents for keywords.
