FAQ
Which AI model will you use for my chatbot?
It depends on your needs and budget. I work with OpenAI (GPT-4o), Anthropic (Claude), Google (Gemini), and open-source models like LLaMA and Mistral. I'll recommend the best fit after we discuss your project or I can use whichever you prefer.
Do I need my own API key?
Yes, you'll need your own API key from whichever provider we use (OpenAI, Anthropic, Google etc.). This keeps your chatbot fully under your control and ensures you're not dependent on me after delivery. I'll guide you through getting it if needed.
Where can the chatbot be deployed?
I can deploy it on your website, web app, or any platform with a chat interface. For CRM or database integration (Premium), I'll connect it to your existing tools like Notion, Airtable, HubSpot, or custom databases.
What is RAG and do I need it?
RAG (Retrieval-Augmented Generation) means the chatbot is trained on YOUR data, your documents, website content, product catalog, or knowledge base, so it answers questions specific to your business. If you want the bot to know your business inside out, you need RAG.
Will I own the source code?
Yes. Full source code is delivered with Standard and Premium packages. You own it completely and can modify or hand it to any developer after delivery.
Can you build a chatbot in my language (not English)?
Yes. Multi-language support is included in the Premium package. The chatbot can detect and respond in the user's language automatically.
