FAQ
Can I get a custom quote?
Yes. Message me with your use case, website or app, required integrations and preferred timeline. I will review the requirements, clarify what is included, and send a custom offer if your project needs a different scope from the listed packages.
Can the chatbot answer using my own documents?
Yes. Standard and Premium include retrieval-augmented generation (RAG), which lets the chatbot use your supplied documents or knowledge base to answer questions. This is different from training a model from scratch. Share sample files so I can assess the data and scope.
Can you build an AI assistant for my business?
Yes. Share the task you want to automate, the tools it must connect to, and any examples. I will confirm what is feasible and recommend a package or custom offer based on the required features.

One of the best developers I've worked with on Fiverr. Mubashir's communication was excellent—his English is clear and professional, which made the collaboration smooth and efficient. He went above and beyond expectations and delivered the chatbot on time, with results that exceeded what I had in mind. Will definitely work with him again!
