Introduction

AI no longer just helps—you can delegate entire blocks of code to it. By 2025, up to 30% of all code in major tech companies is generated using AI. Whether you’re a developer, startup founder, or technical writer, knowing the best AI tools is essential for boosting productivity, reducing bugs, and automating repetitive work.

 

How AI Helps Developers in 2025

🔹 Automatic code generation
🔹 Bug detection and refactoring
🔹 Translation between programming languages
🔹 Commenting and documentation
🔹 Understanding legacy or third-party code

Real Prompt Examples

 

🧪 Example 1: Explaining a function

Prompt:

Explain what this Python function does, and suggest improvements.

python

 

def parse_data(a):

    return [i for i in a if i not in ['null', '', None]]

Copilot / Codeium Output:

This function removes null values from a list. You could improve readability by renaming it to filter_valid_data.

 

🔧 Example 2: Generating SQL query

Prompt:

Write an SQL query to find users who made purchases over $1000 in the last 30 days.

AskCodi Output:

sql

 

SELECT name FROM users

JOIN purchases ON users.id = purchases.user_id

WHERE purchases.amount > 1000 AND purchases.date >= CURRENT_DATE - INTERVAL '30 days';

 

💡 Example 3: Writing unit tests

Prompt:

Generate unit tests for a function that calculates the factorial of a number.

CodiumAI Output:

python

 

def test_factorial():

    assert factorial(5) == 120

    assert factorial(0) == 1
