Two weeks ago I shared the evolution and thinking behind a new user interface design for agentic AI products. We've continued to iterate on this layout and it's feeling much improved. Here's the latest incarnation. Today's AI chat interfaces hit usability issues when models engage in extended reasoning and tool use (aka they get more agentic). Instead of simple back-and-forth chat, these conversations look more like long internal monologues filled with thinking traces, tool calls, and multiple responses. This creates UI problems, especially in narrow side panels where people lose context as their initial instructions and subsequent steps are off-screen while the AI continues to work and evaluate its results. As you can see in the video above, our dual-scroll pane layout addresses these issues by separating an AI model's process and results into two columns. User instructions, thinking traces, and tool calls appear in the left column, while outputs show up in the right column.…
