FAQ
What AI technology do you use for the web apps?
I primarily use OpenAI's GPT models to add smart features like chatbots, content generation, and automation. If you need a different AI model integrated, feel free to message me before ordering.
Can you build a custom chatbot for my website?
Yes! I can build and integrate a custom AI chatbot into your existing website or a new web app, trained to handle your specific use case.
Do I need to provide the OpenAI API key?
Yes, you'll need to provide your own OpenAI API key since API usage is billed directly by OpenAI based on your usage.
Will I get the source code after the project is completed?
Yes, full source code is included with every package so you have complete ownership and control of your project.
Can you add AI features to my existing web app?
Absolutely. I can integrate AI functionality like chatbots, content generation, or automation into your current React/Next.js application.
How long does it take to build the app?
Delivery time depends on the package and complexity of your project, ranging from 5 to 14 days. Custom requirements may need additional time.
Do you offer revisions after delivery?
Yes, each package includes a set number of revisions. Additional revisions are also available as an extra service if needed.
Can I request a custom package based on my specific requirements?
Of course! Message me with your project details before ordering, and I'll create a custom offer tailored to your needs.
