Look Up in the Terminal
On macOS, select terminal text and choose Look Up to read definitions from every system dictionary you have activated, directly in an anchored popover. Open the full Dictionary app only when you want to continue beyond the quick definition.

Why You Need This
How this feature boosts your daily productivity
Terminal output, documentation, and AI responses regularly contain unfamiliar technical or English terms. Copying a word into a browser or switching to Dictionary breaks your reading flow; Look Up keeps the definition beside the selected output and respects the dictionary order you already configured in macOS.
How It Works
Get started in 4 simple steps
Open a Terminal
Click "+" to create a new terminal tab. Choose from Claude Code, Codex, Gemini CLI, Amp, bash, zsh, or custom shells.
Arrange Your Layout
Switch between grid, columns, or fullscreen with one click. Drag dividers to resize panes to your preference.
Run Your Agents
Start your AI agents with pre-configured prompts or type freely. Watch them work in real-time with status indicators.
Monitor & Manage
Use the Terminal Dashboard for a bird's-eye view. Sessions persist across restarts so you never lose context.

Why It Matters
The productivity impact of having terminal & ai agents built into your workspace
Zero Context Switching
All your AI agents and terminals live in one window. No more alt-tabbing between 5 different terminal apps.
Visual Status Tracking
Color-coded tabs and the Kanban dashboard tell you which agents are done, running, or need attention — at a glance.
Persistent Sessions
Tmux-backed persistence means your terminal state survives crashes and restarts. Never lose scrollback history again.
Flexible Arrangements
One-click layouts adapt to your task: grid for monitoring, columns for comparing, fullscreen for deep focus.
