FAQ
What kind of chatbot can you build?
I create smart, context-aware chatbots using LLMs (OpenAI, Gemini, open-source), LangChain, and RAG. They can retrieve data from vector databases like Chroma and integrate with websites, mobile apps, or messaging platforms like WhatsApp.
What is RAG and how does it improve the chatbot?
RAG (Retrieval-Augmented Generation) allows the bot to access external data sources in real time — such as documents, spreadsheets, or knowledge bases — making responses more accurate, dynamic, and tailored to your business.
Can you connect the chatbot to my existing tools or platform?
Absolutely. I offer integration via API, custom widgets, or direct embedding. I can also connect your bot to tools like Notion, Airtable, Google Sheets, or messaging apps to enhance its capabilities and workflow
