FAQ
Which AI model will you use for my chatbot?
It depends on your needs. I recommend Claude for nuanced conversations and GPT-4 for general purpose use. We can discuss the best fit for your budget and use case before starting.
Can you add the chatbot to my existing website?
Yes. I deliver a clean embeddable widget that works on any website regardless of how it was built — WordPress, Shopify, custom code, or anything else.
Will the chatbot remember previous conversations?
On Standard and Premium plans yes — I integrate a database for persistent conversation history. Basic plan chatbots handle single session conversations only.
Can the chatbot be trained on my business information?
Yes. You provide your documentation, FAQs, product info, or any text content and I will engineer the prompts so the bot responds accurately based on your specific knowledge base.
Do I need an API key or paid AI subscription?
Yes. You will need your own OpenAI or Anthropic API account. I will guide you through setting it up — it typically costs a few dollars per month for moderate usage.
