FAQ
What do you need from me to get started?
I’ll need your requirements (topics, FAQs, or features you want the chatbot to cover). For Standard/Premium, I’ll also need your database/API details.
Do I need my own OpenAI API key?
Yes. You will need an OpenAI API key for the chatbot to work. I’ll guide you on how to create one (it’s quick and free to set up billing).
Can you deploy the chatbot for me?
Yes. I provide a step-by-step guide. In Premium, I can also include a Dockerfile or cloud deployment support.
What platforms can this chatbot run on?
It can run on any server or hosting that supports Java or Node.js (Spring Boot / Express), and I’ll give instructions to run it locally or on the cloud.
Will the chatbot have memory?
The Basic version answers FAQs only. Standard and Premium include database support for short-term memory or storing conversation logs.
Do you provide fine-tuning of AI models?
Fine-tuning is available in Premium or as an add-on. This helps customize the bot’s responses to your domain.
Is the ChatGPT API free and how does it work?
No, the ChatGPT API is not free. It works on a pay-per-use system where costs depend on the number of tokens processed. Both your input (the user’s prompt) and the output (the model’s reply) consume tokens, and usage is billed based on the total tokens used.
