Custo

Custo, Generate, and Legal Agents are three separate AI surfaces. This article covers Custo only. Custo is matter-aware conversational AI. It reads your workspace context and can answer questions or take actions depending on the mode you select.

​

Open Custo

• Press Cmd+Shift+I (Mac) or Ctrl+Shift+I (Windows) to open Custo
• Press Cmd+Shift+S (Mac) or Ctrl+Shift+S (Windows) to return to Studio
• Click Ask Custo on any matter or document page

​

Ask mode vs Agent mode

Ask mode (Chat) is read-only. Custo retrieves, summarises, and answers questions. It does not create or modify anything. Agent mode can create tasks, generate documents, run compliance checks, and take other actions. Agent mode is available on Learn and above. Agent mode asks for confirmation before any irreversible action.

​

Attach context

Pin a matter or document to a thread so Custo answers in that context. Click the attachment icon in the composer and select the matter or document.

​

Tool activity

When Custo runs a tool, an activity indicator appears showing the tool name (for example list_matters, search_documents). Expand the indicator to see query details and sources retrieved.

​

Confirmation step

In Agent mode, Custo pauses before irreversible actions and shows a confirmation prompt. Review what Custo is about to do, then approve or cancel. Reply yes or go ahead to confirm. Reply no or cancel to abort.

​

Thread history

Threads are stored per workspace in your browser. Open the thread list in the Custo panel to find previous conversations.

​

Available models

Change the model from the model selector in the Custo composer.

Parity dock

The Parity dock is a lighter quick-assistant panel for short queries. It differs from the full Custo interface. Open it from the bottom-right dock icon on any product page.
