It is so simple to create your integration with all the supplied connectors. I also love the ability to send data to Gsheets and Looker for automation. The best part is being able to chat with your data inside of ChatGPT's. Adzviser really helps you along the way as well. The customer support is superb.

Everything runs fast, accurate, and at a fraction of the cost compared to other tools I’ve tried. The customer support is extremely personal and responsive.
