Ever opened a ServiceNow app and thought: “What exactly does this do?”
That’s where App Explainability comes in — using AI to make app behavior clear for both low-code and pro-code developers.
The new Build Agent, built into the ServiceNow IDE, doesn’t just generate code. One of its most practical and immediate uses is helping us understand existing applications 🙇.
I tested it on a data visualization app and asked questions ranging from high-level architecture to detailed code review:
♦️ Explain the overall structure of the application
♦️ Tell me which visualizations the app provides
♦️ Based on the code, which JS libraries are used in those visualizations?
♦️ Identify the Three.js functions used, with a brief description and documentation
You can see the full log of the interaction in the attached document.
The results? Precise, clear, in-platform — and on par with tools like Cursor or Windsurf.
What you’ll need to try it yourself:
1️⃣ Zurich Patch 1 (ZP1) instance
2️⃣ Now Assist for Creator ≥ 28.1.0
3️⃣ ServiceNow IDE ≥ 3.1.2
4️⃣ App converted to Fluent
