+
+t1chat is a chat-focused mode that transforms the TUI into a conversational interface inspired by [T3 Chat](https://t3.chat). It features a pink/magenta/lavender theme, a flat thread list grouped by time, and a streamlined UI without code-specific tools.
+
+### What changes in chat mode
+
+- Sidebar shows a flat thread list grouped by time (Today, Yesterday, Last 7 Days, etc.) instead of nested projects
+- "New Chat" button and thread search in the sidebar
+- Title shows "T1 Chat" instead of "T1 Code"
+- Git tools, diff viewer, Chat/Plan toggle, and Full access button are hidden
+- Settings and temp chat toggle in the top-right corner
+- Composer placeholder says "Type your message here..."
+- Pink/magenta/lavender color scheme matching T3 Chat
+
+### Run chat mode

+If installed globally:
