/c is your primary workspace for AI conversations. It is organized into several distinct areas, each with a specific purpose. Understanding the layout helps you move efficiently between conversations, tools, and models.
The chat is not just a messaging window — it is a command center. From a single prompt bar you can activate web search, launch deep research, open a canvas editor, trigger agent mode, or start a voice session. Every tool is one click away.
Interface Anatomy
The chat interface is divided into a left sidebar, a central main area, and a right panel that appears contextually based on the active tool.Left Sidebar
The left sidebar is your navigation hub for all conversations and projects. New Chat button. The pencil (compose) icon at the top of the sidebar starts a new conversation. Keyboard shortcut:Cmd+Shift+O on Mac / Ctrl+Shift+O on Windows/Linux.
Search. A search bar at the top of the sidebar searches across all chat titles and conversation content in real time. Click and type to find any past conversation by keyword or topic.
Chat history. All conversations are listed chronologically in groups:
- Pinned — chats you have explicitly pinned; always at the top
- Today — conversations active in the last 24 hours
- Yesterday — conversations active the prior calendar day
- This Week — earlier conversations from the current week
- Older — everything before this week, in reverse chronological order
Main Chat Area
The central column displays the active conversation thread. Message layout. User messages appear right-aligned; AI responses appear left-aligned with the model’s avatar indicator. Responses stream in real time as they are generated. Message actions. Hover over any AI response to reveal action icons:- Copy — copies the full response text to clipboard
- Regenerate — asks the model to produce a new response to the same prompt
- Thumbs up / Thumbs down — provide feedback on response quality
- Edit — available on your own messages; edit and resend
Prompt Bar
The prompt bar sits at the bottom of the main chat area and is the primary input control for every interaction. Model selector. The model name on the left of the prompt bar is a clickable button. Click it to open the model picker — a searchable panel listing all 95+ models from 19 providers. The selected model handles your next message. Tool pills. A row of tool buttons is displayed above or inline with the text input. Each pill activates a specific capability for the current message:| Tool Pill | What It Does | Plan |
|---|---|---|
| Web Search | Searches the live web and cites sources inline; choose from 8 focus modes | Free (1/day), Pro+ |
| Deep Research | Launches a multi-step autonomous research task with plan approval | Free (1/day), Pro+ |
| Canvas | Opens a side-by-side canvas editor (7 editor types) | Free+ |
| Agent Mode | Enables multi-step agentic actions using connected apps as tools | Pro+ |
| Voice | Activates real-time WebRTC voice input and output | Pro+ |
Enter to send. Press Shift+Enter to insert a new line without sending.
Send button. The arrow icon sends your message. During generation, the send button becomes a stop button — click it or press Escape to halt the response mid-stream.
Right Panel (Contextual)
The right panel appears automatically based on the active tool and is hidden when not in use. Sources panel. When Web Search is active and the model has fetched sources, they appear in the right panel as expandable cards showing the source title, URL, and a relevant snippet. Click any source to open it in a new tab. Agent activity panel. When Agent Mode is active, the right panel displays a live log of the agent’s actions — each tool call, intermediate step, and reasoning step is shown as it happens. This gives you full visibility into what the agent is doing in real time.Topbar (Page Navigation)
When navigating to non-chat pages, a topbar appears with navigation links. This is visible on pages like/files, /tasks, /agents, /apps, /studio/images, /studio/video, and /studio/audio. The topbar lets you move between ZeroTwo’s primary workspaces without going through the chat sidebar.
