FAQ
What kinds of AI chatbots do you build?
Custom AI chatbots for support, lead generation, internal knowledge assistants, and website concierge bots. Each is grounded in your own content, answers in your brand voice, and runs 24/7 across your site and other channels. Tell me your use case and I will suggest the best setup.
Can the chatbot answer from my own documents and data?
Yes, that is my specialty. Using retrieval-augmented generation (RAG), the bot answers from your PDFs, docs, website, help center, or database instead of guessing. You can update the knowledge base anytime and it stays current.
Which AI models and tools do you use?
OpenAI (GPT), Anthropic Claude, LangChain, and vector databases like Pinecone or pgvector for retrieval. I choose the mix that best fits your accuracy needs and budget, and I explain the trade-offs before we start.
Can you embed the chatbot on my website or connect other channels?
Yes. I deliver an embeddable website widget (a script you paste in), an API your team can call, or integrations with channels like WhatsApp, Slack, or Messenger. It can also handle multiple languages if your audience needs it.
Can the chatbot capture leads and hand off to a human?
Yes. It can collect and qualify leads and escalate to a real person when a question is beyond its scope, logging the request for your team to follow up. You get the speed of automation while staying in control of key conversations.
How do you keep answers accurate and avoid made-up replies?
I ground every answer in your approved content with RAG and add guardrails so the bot admits uncertainty instead of inventing answers. I test it on real questions before delivery, and for higher-stakes cases I set up evaluation to measure quality.
What do you need from me to get started?
Share the documents or links the bot should learn from, a short description of your goals, and a few example questions it should handle well. If you have branding or a preferred tone, send that too. The more context you give, the better the result.
How long does it take, and what does it cost?
A simple document-based chatbot usually takes a few days; an advanced custom build takes longer (see the packages above). Scope and price depend on your data and integrations, so message me with your use case for a clear quote and timeline.
Is my data kept private and secure?
Yes. Your documents and data are handled confidentially and used only to build your chatbot, never shared. I can also build on your own accounts and API keys so the data and running costs stay entirely under your control.
Do you offer revisions, support, and ongoing maintenance?
Yes. Every package includes revisions, and I offer ongoing support and maintenance (including a monthly option) to update the knowledge base, monitor quality, and add features as your needs grow. I keep communication prompt throughout.

Working with Younes exceeded my expectations. He is very knowledgeable and knows how to quickly trouble shoot problems as they arise. The final product was exactly what I was envisioning for my project. He even helped me troubleshoot some things after we were done working together. Definitely using his service again.
