Diaflow's interface is one of the reasons why people should consider buying it. First impression and ease of use are critical for appsumoling's early adoption, so I think Diaflow got these right. ----The server is quite fast too, which is crucial especially when it comes to designing the workflow which can be quite daunting during the trial and error.
-People with low code should be happy to know that Diaflow is quite intuitive, as the learning curve is not that steep. The fact that Diaflow AI chatbot is there to help us analysing errors and their Discord channel is very active helps a lot.

-The only issues that need rectify are some inaccessible links on their websites (apparently their website is being overhauled) and the lack of templates and integration.

-The value of Diaflow will grow overtime but they need to improvise on their template flow. If more basic automation can be done without the involvement of AI credits, it will be more valuable and sustainable. In my case, simply converting triggers into JSON and add them into Diaflow tables requires an intervention of AI prompt to make it possible, because of the formatting output. It could be a win-win for developers if Diaflow team can make simple automations template like this with less AI involvement, saving AI credits for more complex automation/apps.

Let's hope for a better templates in the future.
