## Definition

A **TUI (terminal user interface)** is a text-based interface that runs inside a terminal, letting you interact with a program through keyboard input and rendered text rather than graphical windows and buttons.

In this channel's material, a **_TUI (terminal user interface)_** is the text-based way of driving a tool from inside a terminal — the surface developers have traditionally used to interact with command-line coding agents. The concept appears as the contrast point in the discussion of OpenAI's Codex app: the team explains why building a **GUI** beat shipping yet another terminal tool [^619ac4a8-531a-53a9-9188-912ae7459502@0]. That is, the Codex app deliberately moved away from the TUI model that most coding agents had used, and the video explores what that switch unlocked for day-to-day agent workflows. Treat the framing as the team's own account of their design choice rather than an independent evaluation.
