Perguntas frequentes
What is RAG and why do I need it?
RAG links an LLM to your private data. Instead of guessing, your chatbot answers using your real files, websites, or databases. This stops wrong facts and gives exact, helpful replies. It works great for support teams, company wikis, and document search tools.
What data sources can you connect?
I can connect PDFs, DOCX, TXT, websites (web scraping), databases (SQL, MongoDB), and APIs. Your chatbot will answer questions based on your actual data, not generic AI knowledge.
Do you provide source code?
Yes! I provide complete, well-documented source code with every project. You will own the code and can modify it as needed. Deployment assistance is included in the Premium package.
How long does it take to build a RAG chatbot?
A basic RAG system with 1-3 documents takes 3 days. A full custom system with multiple data sources, custom UI, and deployment takes 5-10 days depending on complexity.
Can you integrate the chatbot with my website or app?
Absolutely! I can integrate your chatbot with websites (React, Next.js, HTML), WhatsApp, Telegram, Slack, or custom APIs. This is included in the Standard and Premium packages.
