Do I need to provide my own OpenAI API key?
If you choose to use OpenAI’s GPT models, yes—your API key is needed to connect and run the model. I’ll guide you through the setup if you need help.
Is the chatbot multilingual?
Yes, if the chosen model supports multiple languages, your chatbot can respond in various languages. Just let me know your language preference during setup.
Will I get the source code?
Absolutely! Full source code will be provided upon delivery, so you can modify or extend the app as needed.
