Chatbot

The Chat experience itself hasn't changed in any fundamental way — you can still pick any model, use agents, run the toolkit, branch conversations, and generate images inline. What changed is how you start a chat and where context lives.

In the old UI, everything was inside the chat screen itself: a New Chat button at the top-left, and sidebar tabs (History, Knowledge, Files, Prompts) that you'd open to load context into your conversation. This made the chat UI feel crowded, especially on smaller screens.

In the new design, starting a chat is even simpler — just type in the Home prompt box and you're in. Context (knowledge bases, files, saved prompts) has moved to its own dedicated section called Context in the left rail, giving it more space and better organisation than sidebar tabs ever could.

Before

Old Write & Chat page showing left sidebar with New Chat button, History/Knowledge/Files/Prompts tabs, and main area with How can I help you today prompt and model/agent/toolkit row

Everything was in one place: nav, context tabs, and the chat itself. Useful, but the sidebar tabs were small and the chat area felt constrained.

After

New Chat empty state leading with agent cards: General Assistant, Copywriter, Code Helper, Create your own, and Browse all agents link below

The new chat empty-state surfaces agents upfront — the most common starting point for structured tasks. The prompt box is at the bottom; context is managed separately in the Context section.

Was	Now — and why it changed
New Chat button in sidebar	Type on Home, click ＋ in the rail, or ⌘⇧O — start from anywhere
Agents hidden in a small prompt-bar dropdown	Agents lead the empty state; same dropdown available mid-conversation
Toolkit as a single prompt-bar toggle	Toolkit side panel — all 12 tools visible and individually toggleable
Sidebar tabs: History, Knowledge, Files, Prompts	Moved to Context in the left rail (see section 8)
Model selector, Chat Branching, Thinking Depth, Temperature	All unchanged — same location, same controls
