Custom Assistants
Assistants are custom AI personas you create and store locally. Each assistant packages a model, system prompt, enabled tools, skills, and an avatar into a single switchable identity.
What is an Assistant?
Section titled “What is an Assistant?”Think of an assistant as a pre-configured AI persona optimized for a specific purpose. For example:
- A Code Reviewer assistant that uses GPT-5.2, has a strict code review system prompt, and always has the Read, Grep, and Glob tools enabled
- A Research Analyst assistant that uses Claude Sonnet 4.6, has a research-focused prompt, and defaults to Web Search + Web Fetch
- A Shell Expert assistant that uses a fast local model, focused on command-line help
Each assistant is completely local — no cloud sync, no account required.
