How to Use AI Coding Assistants to Write Your First 100 Lines of Code

Starting your coding journey can feel daunting, especially when you stare at a blank screen wondering where to begin. The good news? AI coding assistants can help you write your first 100 lines of code faster than you might think. In 2026, these tools are more powerful and accessible than ever, making coding more approachable for solo founders and indie hackers.

Why Use AI Coding Assistants?

If you're new to coding, you might wonder why you should consider using AI tools. The reality is that AI coding assistants can significantly reduce the time it takes to write code, provide instant feedback, and help you learn as you go. They can suggest code snippets, identify errors, and even explain concepts in real-time. But with so many options, which ones are worth your time and money?

Prerequisites Before You Start

Before diving in, you’ll need a few things:

• Basic understanding of programming concepts: Knowing what variables, loops, and functions are will help you get the most out of these tools.
• An IDE or code editor: Popular choices include Visual Studio Code (VS Code), IntelliJ, or even a simple text editor.
• An account with your chosen AI coding assistant: Many offer free tiers, but some features may require a subscription.

Time Estimate

You can finish your first 100 lines of code in about 2-3 hours using AI coding assistants, depending on your familiarity with coding concepts.
