How I Built Software from Scratch with Google Antigravity: My Experience

To be honest? I was skeptical.

In a world flooded with AI tools that promise miracles but deliver only basic responses, I approached Google Antigravity with reservations. I thought: "Okay, another chatbot. It'll write me two lines of code and then freeze."

Today I want to tell you why I was wrong. And how in just a few minutes I turned an idea into a professional, working product.

The Task: Next-Generation PDF Editor

My idea was simple but technically challenging: I wanted to create a PDF editor that runs entirely in the browser. No file uploads to servers, no risk to personal data, no monthly fees. I wanted speed, security, and modern design.

I asked Antigravity. Instead of the standard "Here's sample code for a button", I got something different. I got a partner.

The Process: More Than Just Coding

Antigravity didn't just generate code. It understood context.

When I asked for a "progress bar", it didn't just add a bar – it connected it with asynchronous processing operations.

When I said "I want it to look beautiful", it created a modern, "glass" interface with a dark theme and smooth animations that looks like a $50 application.

Together we built features that typically take days:

  • Drag & Drop system for page reordering – intuitive and fast
  • Image to PDF conversion – with automatic resizing
  • Smart watermarks – text or logo, embedded directly into the document
  • Multilingual support – switching between Bulgarian and English with one click

Asked Antigravity

The Moment of Truth

The most impressive part wasn't that the code worked. It was how we handled problems. When one library refused to work (due to an outdated version), Antigravity immediately diagnosed the issue, suggested an alternative, and rewrote the logic without losing momentum.

This isn't just a tool that "executes commands". This is an agent that thinks in perspective. It remembers what we did 5 steps ago, suggests improvements I hadn't thought of, and most importantly – writes code that is structured, clean, and production-ready.

The Result

Today I have a fully functional PDF Editor. It's not just a prototype. This is a tool I use daily. And we made it together – I provided the vision, Antigravity provided the engineering power.

If you're wondering whether the future of programming is here – yes, it's here. And it's called Google Antigravity.
