Designing the Human Element: Three New Considerations for AI-Driven Applications

At Catio, we’re building the copilot that architects and their organizations can trust to make smart, context-aware architecture decisions. That means we think deeply not just about what AI can do, but how it should behave. How it builds trust. How it engages users. How it earns its seat at the table.

Our Product Manager, Dipock Das, recently published a three-part series exploring how product and engineering leaders can and must approach AI design differently. Whether you're building a copilot, agent, or embedded LLM capability, these are the new first principles.

We’re syndicating the series here for our community, with links back to the original posts:

Part 1: Voice, Tone, and Persona – Giving Your AI Character

Your AI is becoming your user interface. Do you know who it is?

In this first post, Dipock makes the case that AI applications are no longer tools—they're team members. And just like any team member, users need to know who they’re dealing with. Will your AI feel like a confident advisor, a deferential assistant, or a friendly peer? The answer shapes user trust, engagement, and adoption.

“The AI’s voice isn’t a gimmick—it’s a contract. It tells users what to expect, and what not to.”

Highlights:

• Align your AI’s persona with your user personas
• Define tone, language, empathy patterns, and response models
• Avoid robotic sterility or over-apologizing “Clippy” syndrome

Part 2: Don’t Just Ship the Model – Why AI Guardrails Are Mission Critical

If your AI is a new team member, you need to set boundaries. Clearly.

In Part 2, Dipock introduces a framework every AI product leader needs to internalize: security and behavioral guardrails. He calls out the “lethal trifecta” of vulnerabilities—access to private data, exposure to untrusted content, and external communication—and offers a practical path to mitigate risk through internal controls.

“Treat your AI like a new employee. Would you let a new hire send emails to customers without any training or access controls?”

Key takeaways:

• Implement data minimization and input validation
• Enforce RBAC—don’t assume the LLM will
• Monitor outputs for alignment with brand voice and ethical standards

Part 3: Beyond the Prompt – Designing for True AI Interactivity

You’ve built a powerful model. Now teach users how to dance with it.

In the final installment, Dipock applies game design principles to AI UX. He addresses the “silent comedian” problem—powerful AI hidden behind a blank chat box—and introduces four essential techniques to help users onboard, explore, and master interactions.

“Prompting is not second nature. You have to earn that interaction.”

Included:

• Interaction Loops to teach through feedback
• Perceived Value to deliver wins early and often
• Skill Chains for progressive learning
• Burnout prevention through user feedback and feature evolution

Why This Matters at Catio

Catio isn’t just building another LLM wrapper. We're architecting a strategic copilot that engineers, tech leads, and CTOs trust to make high-stakes architecture decisions. For us, designing the human element—persona, guardrails, and interactivity—is just as important as model accuracy or integration fidelity.

Catio’s platform combines:

• Real-time architecture observability
• Personalized, plan-aware AI recommendations
• System behavior modeling and scenario simulation
• Guided decision workflows for architects and leadership teams

Because if your AI doesn’t feel like part of the team and behave like one, it’s not ready for the decisions that matter most.
