Built a micro-product: 100 AI voice assistant keywords for programmatic SEO builders

I noticed AI voice assistants have a surprising amount of underserved long-tail commercial search terms.

So I mapped:

• 100 low-competition keywords
• grouped by industry
• monetization ideas
• 20 site concepts

Built it as a small Gumroad product to test demand.

Mainly curious:
Would you monetize this as SaaS affiliate, directory, or rank-and-rent?
