FAQ
Which AI models do you use for the chatbot?
I primarily use OpenAI GPT-4 and GPT-4o, but I can also integrate Claude (Anthropic), Gemini (Google), or any open-source model like Mistral or LLaMA depending on your requirements and budget.
Can you integrate the chatbot into my existing website or app?
Yes! I can integrate the chatbot into any website via a JavaScript widget, or into mobile apps via REST API. I also support Telegram, Slack, WhatsApp, and Discord integrations.
Do I need to provide my own OpenAI API key?
Yes, you will need your own API key for the AI model (OpenAI, Anthropic, etc.). This ensures full ownership and control of your chatbot costs. I will guide you on how to set it up securely.
