I see it may be a bit more complex than I had intially thought. Might I suggest a pricing table kind of thing showing some basic plans and usage and price points?
Something as simple as a few basic use cases, android app, no engineering support, under 10,000 unite, x price for example maybe.
I'm a small developer and tinkerer, so my choice to explore more on not is really price sensitive. However I do also consult with other groups, and may suggest your product as a fit if it meets other criteria I look for "private voice AI" - you've already checked a few boxes!
However, any time I see a "contact us for price inquiries" - I shut down. I know if they can't tell me the price on the page I can't afford it. At that point I don't bookmark the site, I don't research any further, and it reinforces the
awesomeness of other projects I've put into my memory for use.
This is not just you, it's a lot of projects/ site on the web.
