Talk Like You Mean It

A Designer’s Guide to Conversational Interfaces

Conversational interfaces are not merely technical systems. They are designed conversations that shape trust, behavior, power, memory, and human relationships. Designers are responsible not just for what systems can say, but for how those systems influence the people who use them.

Note: This book is being published chapter by chapter as a living draft. Sections marked TBD are placeholders for material that is still in development, and the structure may change as the ideas evolve. What you’re reading here is part of an ongoing writing and design process. The final compiled version will be refined, expanded, and polished based on these early drafts.
