Questions & Answers

As answered by people managing HTML PDF API and Zillinity.

Which are the primary technologies used for building your product?

Zillinity's answer:

React.js, Elysia.js, PostgreSQL, Claude AI, Eleven Labs

What makes your product unique?

Zillinity's answer:

Zillinity is the only wellness app built around an immersive ambient space experience. Rather than handing you a checklist or a streak to maintain, Zillinity gives you a sensory environment with original music and mood-responsive atmospheres that lets you channel whatever you're feeling into something greater. Journaling, mood awareness, and AI-powered reflection tools are all woven into that experience, so wellness doesn't feel like another task. It feels like a space you actually want to be in.

Why should a person choose your product over its competitors?

Zillinity's answer:

Choose Zillinity if you want wellness to feel immersive and intentional instead of performative. Most wellness apps gamify your habits with streaks, points, and nudges. Zillinity does the opposite. It meets you where you are, without pressure, and creates a beautiful digital environment where you can explore your inner world at your own pace. It's less about optimizing yourself and more about understanding yourself.

How would you describe the primary audience of your product?

Zillinity's answer:

Zillinity is built for people who are intentional and thoughtful about how they use technology. They're not anti-digital, they're pro-digital wellness. They're tired of doom scrolling, rage bait, and apps that make them feel like they have to optimize every aspect of their lives. They want a digital experience that actually feels good, one that helps them slow down, reflect, and meet themselves where they are.

What's the story behind your product?

Zillinity's answer:

Zillinity started with a personal frustration. As someone who'd always gravitated toward lo-fi channels and ambient spaces online, I found that over time they started feeling clichรฉ and weren't meeting me where I was in my life anymore. I needed something that could hold space for whatever I was feeling and help me channel it into clarity and focus, not just background noise. I also kept noticing how much my mood quietly shaped my productivity and how little most tools acknowledged that. We're feeling, sensory creatures. So I built the digital space I couldn't find anywhere else: one that feels as good as it functions, and helps you understand yourself in the process.

Who are some of the biggest customers of your product?

Zillinity's answer:

Zillinity is in its early stages. We don't have notable enterprise customers to highlight yet, but we're growing a community of early adopters who believe in building a more intentional relationship with technology.
