FAQ
Can the agent use my own data and documents?
Yes — that's RAG. I'll embed your PDFs, websites, Notion or Google Docs into a vector database so the agent answers from YOUR knowledge instead of hallucinating.
Can the agent take real actions, not just chat?
Absolutely. I build tool-calling agents that hit your APIs, update CRMs, send emails, query databases or trigger workflows. That's the whole point of an agent vs. a basic chatbot.
Which LLM should I use — OpenAI, Claude, or open-source?
Depends on the use case. OpenAI (GPT-4o/5) for breadth, Claude for long context and reasoning, open-source (Llama / Qwen) if you need to self-host. I'll recommend based on your needs and budget.
What if I'm not technical?
Most clients aren't. Just describe what you want the agent to do in plain English and I'll handle the tech, with clear human-friendly explanations of any trade-offs.
