What content can the chatbot learn from?
The chatbot can use PDFs, website pages, FAQs, text documents, product information, policies, manuals, and other structured business knowledge.
Are OpenAI API and hosting charges included?
No. API usage, hosting, vector database, domain, and other third-party charges are not included. You must provide the required accounts or API keys.
Can you integrate the chatbot into my website?
Yes. Website integration is included in the Standard and Premium packages. Please share your website technology before ordering.
Will I receive the source code?

Can you connect the chatbot to my database or CRM?
Database or API integration is available in the Premium package or as a custom extra. Contact me first so I can check the platform and integration requirements.
