Pattern: Guided Learning

Today's Takeaway

Trust as a Design Constraint

Perplexity's decision to abandon advertising highlights how trust considerations are becoming primary design constraints in AI products. As AI capabilities expand through skills ecosystems and platform integrations, maintaining user confidence requires careful separation of AI assistance from commercial interests. Design for transparency about AI capabilities and limitations rather than optimizing purely for engagement or revenue.
