Designing Trustworthy AI Products

You are advising a company that is turning a widely used AI assistant into a business. Analyze the trade-offs between subscription models, advertising, data access, and user privacy. What product choices preserve trust while still creating revenue? Include examples of ad placement, transparency, opt-out controls, and guardrails for sensitive use cases. Then propose a go-to-market strategy for launching an AI assistant in a market where users are highly sensitive to reliability and fairness.
