Chief organizes your work around a handful of building blocks. Knowing what each one means makes everything else faster. Here’s the short version.The glossary
- Projects — shared workspaces that hold Files, chats, and members. The unit you collaborate in.
- Chats (chat threads) — your conversations with Chief.
- Library — where you upload documents, data, and other files to reference in your chats.
- Files — the individual documents in your Library.
- Labels — tags you apply to Files to organize them.
- Collections — let you create sophisticated “fences” around your data using boolean and/or filtering of Labels.
- Concepts — topics you define; Chief continually monitors your Files to surface the parts most relevant to each one.
- Skills — specific abilities. Mention a Skill in your chat to invoke that ability.
- Expert Voices — customize how Chief responds, so it thinks and responds as a subject-matter expert.
- Actions — automatically trigger a chat response on a schedule or whenever new data is added to a chat’s scope.
- Memories — persistent notes that help Chief personalize its responses to you.
- Live Sessions — capture meetings (via the desktop app), recording decisions and follow-ups.
- Command Center — the hub behind the + button in the prompt bar for uploads, settings, and more.
- Advanced Mode — a user-mode setting that reveals extra capabilities like Concepts and Collections.
- Agents — specialized intelligence workers Chief spins up to get larger jobs done.
ℹ️ Good to Know: Chief also has intelligence levels you’ll see while chatting: Automatic, Fast, Expert, and Deep Intelligence. Automatic switches between Fast and Expert based on the complexity of your prompt; Deep Intelligence deploys a fleet of long-running agents and requires a paid subscription.
