AI Cost Lens
What did one usable result really cost?
Estimate a route from published prices. With matched cost, usage, and checked outcomes, see whether a cheaper option still holds up after quality and rework.
Before you invest it, spend it, or build with it, understand it.
I’m Diana. I help growing tech teams understand cloud, AI, and software costs, and service businesses improve recurring work. I also build tools, teach investing concepts, and write about markets and money. If the story and the numbers disagree, I want to know why.

Hi, I’m Diana. I like a good money question.
I started out as a beauty advisor, then worked in pet salons. I began following the markets in 2020, earned a finance degree, and later worked in wealth management at Morgan Stanley.
Today I help growing tech teams understand cloud, AI, and software costs, and service businesses improve recurring reporting and put useful tools to work. I also build free tools, write Markets & Mimosas, and teach investing and trading concepts through worked examples.
