Test your code on three different AI models in 8 minutes

Compare logic and find bugs in your code using free versions of leading neural networks

1.Open ChatGPT and paste your code with a request to find bugs and check the logic.
Use the free version of GPT-4o mini for an instant response. Do not submit work code with keys, passwords, or trade secrets: it goes to the servers of all three services. For testing, use a fragment without sensitive data.
ChatGPT ↗About this tool
Prompt
```
Review the following code for bugs, logical errors, and potential edge cases. If there are issues, provide a corrected version and explain why the changes were made:

[Paste your code here]
```
What this prompt doesThe prompt asks the AI to check the code for bugs, logical errors, and edge cases, then suggest a corrected version with explanations. Replace [Paste your code here] with your source code.
2.Go to Claude.ai and submit the same code to get an alternative perspective on architecture and code cleanliness.
Claude often does a better job of writing clean and concise code than GPT.

What this prompt doesThe prompt focuses on analyzing code efficiency and readability. Replace [Paste your code here] with your code.
3.Open Google Gemini and ask the model to create several test cases for your code.
Gemini is great for generating testing ideas.

```
What this prompt doesThe prompt asks to generate a list of 5-10 test cases (positive and negative) for full functionality verification. Replace [Paste your code here] with your code.
4.Compare the answers: if all three models pointed out the same bug - it is critical. If the answers differ - choose the most well-reasoned solution.
Pay attention to the 'why' explanations the model gives for each suggested change.
