Building Quilon with Claude Code

How we used AI-assisted development to build a cross-platform clipboard sync app in record time.

Quilon was built with Claude Code, Anthropic's AI coding assistant. This isn't a gimmick or a marketing claim — it's a fundamental part of how we work.

What is "Vibe Coding"?

Vibe coding is a term that's emerged for AI-assisted development where you describe what you want in natural language, and the AI generates the code. It's not about replacing developers — it's about amplifying them.

With Claude Code, I can describe a feature like "add a notification when clipboard sync fails with a retry button" and get working code in seconds. Then I review, test, and refine.

Why Claude Code?

I've tried other AI coding tools. Claude Code stands out for several reasons:

  • Context understanding: It reads my entire codebase and understands the patterns I'm using
  • Consistency: Generated code matches my existing style, imports, and conventions
  • Security awareness: It catches potential security issues and suggests better patterns
  • Iterative refinement: I can say "make it more efficient" or "handle the edge case where..." and it adapts

A Real Example

When building the encryption layer, I described what I needed: "AES-256-GCM encryption for clipboard data with a unique IV per message, key derived from device, and the ability to encrypt both text and binary image data."

Claude Code generated the initial implementation, including proper IV handling, key derivation, and type-safe interfaces. I reviewed it, asked for a few adjustments (like adding explicit typing for the encrypted payload format), and it was done.

What would have taken hours of documentation reading and trial-and-error took minutes.

What AI Can't Do

AI-assisted development isn't a replacement for thinking. I still make all the architecture decisions, review every line of generated code, and write the parts that require deep domain knowledge.

Claude Code is a tool — an incredibly powerful one — but it's not a developer. It doesn't understand user needs, product strategy, or why certain tradeoffs matter. That's still my job.

The Productivity Gain

Building Quilon with Claude Code has probably been 3-4x faster than without it. Not because the AI writes all my code, but because:

  • Boilerplate disappears — I describe what I want, not how to wire it up
  • Documentation lookup is instant — Claude knows the APIs
  • Refactoring is trivial — "convert this to use React hooks" just works
  • Testing is faster — "write tests for this function" generates good test cases

The Future of Development

I believe AI-assisted development is the future. Not AI replacing developers, but AI as the most powerful tool in a developer's toolkit.

Quilon is proof that you can build production-quality, security-critical software this way. We're proud to put "Built with Claude Code" in our footer.
