I see OpenAI have invented Alexa Skills. Lots of copy in this documentation saying how they shouldn’t be used for ads, or promoting users to come back to your company’s app, while these will absolutely be used for ads and feature prompts to come back. https://developers.openai.com/apps-sdk/concepts/design-guidelines/
My prediction is that these will be about as successful as Alexa Skills turned out to be, because very few processes are enhanced by playing a guessing game to work out what some software can do.
I know Alexa Skills were largely not a thing because at one point Amazon decided to pay me £80 a month out of the blue, apparently a skill I’d spent half an afternoon throwing together, and that was almost literally a random phrase generator, was one of the most engaged with skills at the time. They only stopped because I didn’t update it to use a new API so it got delisted.
