AI Integration & Chatbots (OpenAI, Claude)
Hire Marwan Ayman for ai integration & chatbots (openai, claude)
I add AI where it saves real time: chatbots that answer from your own documents (RAG), lead and email classification, document and invoice extraction, content drafts, and AI steps inside n8n workflows, using the OpenAI or Claude API. Each integration ships with guardrails, logging and a small evaluation set so you can see how often it is right. Typical cost is $200 to $1,500.

Questions about this service
- Will an AI chatbot make things up?
- It can, which is why answers are grounded in your documents, show their sources, and fall back to a human when confidence is low. The evaluation set measures how often it is right before launch.
