🧠 LLM
You talk to the Software → it sends tasks to an Agent → the Agent uses the LLM brain to think
🏠 House analogy: The brain living inside the house. It knows everything — but it just sits there and thinks. It doesn't open doors or make phone calls on its own.
An LLM is a massive AI trained on billions of pages of text. It can read, write, summarize, answer questions, write code, and have conversations. Examples: ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google).
It's incredibly smart — but on its own, it just responds to text. It can't browse the internet, send emails, or take real-world actions without help.
Real example
You type: "What causes an AC unit to stop cooling?" → The LLM gives you a detailed answer. That's it — just text in, text out.
🏠 House analogy: The person living in the house. They USE the brain to make decisions — and then actually DO things. Open doors, answer the phone, book appointments.
An AI Agent is software that uses an LLM as its brain AND takes real actions. It can browse the web, send emails, read files, call APIs, book calendars, send texts — anything a human could do on a computer.
The Agent is what makes AI actually useful in the real world. It decides WHAT to do, asks the LLM HOW to do it, then carries out the action.
Real example — JobsiteAI
Customer texts "my AC is broken" → Agent reads it → asks LLM how to respond → sends a friendly reply → collects their info → books a Google Calendar event → texts the owner. That's an Agent doing real work.
🏠 House analogy: The house structure — walls, doors, windows, plumbing. It's what holds everything together and lets people interact with what's inside.
Software is the application you (or your customers) actually see and touch. The website, the app, the dashboard, the text message interface. It's the front door to the AI.
Software connects the user to the Agent. Without it, the Agent has no way to receive input or deliver output to the real world.
Real example — Axiomare
axiomare.ai is the Software (the house). When a customer texts +18339745797, that's the front door. The Agent inside handles their request using the LLM brain. The dashboard at dashboard.axiomare.ai is the control room.
