What Are AI Tools?

An AI tool is an app or website that lets you use an AI model by typing, talking or uploading a file. ChatGPT is a tool; the GPT models behind it are models.

Getting started with AI tools sets out the main types, from chat and coding assistants to tools that make images and voice.

The other guides go a level deeper. The Model Context Protocol is an open standard that connects AI apps to outside tools and data, documented at modelcontextprotocol.io. Running models locally explains what Ollama, llama.cpp and vLLM each do. MCP servers are listed on the MCP servers page.
