ClaudeAlmost everyone has realised that AI is steadily automating large parts of the application development process. By our estimates, AI could handle a significant share of routine app development by the end of this year. Traditionally, the preparation phase alone can take weeks before a developer writes a single line of code. With Claude Code, much of that groundwork is compressed into hours or even minutes. The actual coding sprint is shorter as well. Even non-technical builders are now shipping end-to-end applications in minutes instead of days, turning ideas into working products at a pace that would have seemed unrealistic just a year ago.
Applications like Chrome browser extensions are trivial for Claude compared to the complex, large-scale systems it can handle. Right now, hundreds of software projects are being built with it. Some developers are understandably uneasy about the shift. While, non-technical creators see it as leverage, knowing they can move faster and avoid spending thousands on development fees just to get a first version live.
This tutorial shows how to build a Chrome extension with Claude Opus 4.6. You don’t need Claude code to build your first Chrome extension. Claude Chat can handle it like a pro. We will show you how to plan the extension development, write a prompt, download and extract the ZIP file, and upload the extension using Chrome Extension Manager. It’s going to be super easy, and you can create your first Chrome extension in minutes.
By the end of this tutorial, you’ll be able to:
Plan the extension development
Access Claude Opus 4.6 Extended model
Download the files created by Claude
