Creating custom tools for your website can seem daunting, especially if you lack coding skills. However, with the help of modern AI, such as GPT-4o, it’s entirely possible to develop useful tools without writing a single line of code yourself. In this article, I will walk you through the process of building a simple no-code solution as tax calculator for sole proprietors in the USA using HTML code generated by GPT-4o.
Step 1: Understanding the Requirements
Before diving into the technical details, it's essential to outline what you need your tax calculator to do. For this project, the goal is to create a tool that helps sole proprietors estimate their taxes based on their income. The calculator will consider the standard deductions and tax brackets relevant to sole proprietors in the USA.
Step 2: Using GPT-4.0 to Generate HTML Code
With a clear understanding of the requirements, the next step is to leverage GPT-4.0 to generate the HTML code for your tax calculator. Here’s how I approached it:
Prompt to GPT-4o:
Generate HTML code for a simple tax calculator for sole proprietors in the USA. The calculator should take income as input and provide an estimate of the taxes owed based on standard deductions and tax brackets.
It will generate HTML code. You should save the code inside empty .html file. And then you can test it opening the file in your prefered browser.
Step 3: Add more changes according to the requirements
While the generated code provides a basic framework, it may need adjustments to handle more specific cases. For example, you might need to incorporate additional deductions or state-specific tax rules. This is where a detailed understanding of tax laws comes into play.
To refine the tax calculation logic, I used the following prompt with GPT-4o:
Add possibility to choose state using dropdown list for calculator
or you can change user interface for your calculator
Fill submit button background into white and border in black colors
Step 4: Testing and Validating your free no-code solution
Once the code is updated, it's crucial to test the calculator with various income scenarios to ensure accuracy. Check against current tax tables and rules to confirm that the calculations are correct. If the results are incorrect, revisiting the logic and making necessary adjustments is key.
Step 5: Continuous Improvement
Building tools using GPT-4.0 or similar technologies involves continuous learning and improvement. Engage with users to gather feedback, and keep refining the tool to better meet their needs.
Complexities and Constraints
When building a specific tool like a tax calculator, complexities include accurately reflecting intricate tax laws and regulations, incorporating numerous brackets and deductions that change annually, and handling various edge cases such as very high or very low incomes. User input validation is crucial, ensuring the calculator handles non-numeric values, negative numbers, or extreme incomes gracefully. Constraints involve managing the length and complexity of AI interactions, as prolonged conversations can lead to inconsistent results. GPT-4o cannot cover the complex business logic of a calculator without concise and clear prompts that include very specific details on how the calculator should work. Users cannot simply say, "Please find out the correct state tax brackets for 2024 and include them in the calculator," because each state has its own brackets, requiring precise and individual instructions for accurate implementation. Clear, concise prompts are essential, and thorough testing and validation against reliable tax tables are necessary to ensure accuracy and reliability.

Conclusion
Creating a tool like a tax calculator for your website without knowing how to code is entirely feasible with the help of AI. By following the steps outlined above and leveraging the power of GPT-4o, you can develop useful and functional tools to enhance your site. Remember, detailed logic and continuous testing are essential for accuracy and reliability.
