A bash and zsh shell with LLM prompting built in
Start any line with a capital letter to send it to the AI as a prompt, while normal lowercase commands behave exactly as before.
The model receives your recent commands and their output, so follow-up questions like 'why did that fail?' get grounded answers.
Copilot-style command suggestions appear in the shell and can be applied with Tab, informed by your recent history.
Trigger an autonomous loop with ! to have the model propose commands toward a goal, or !! to let it run them without confirmation.
Run many coding agents in parallel, each in its own worktree
Each agent gets its own isolated Git worktree, so multiple agents can edit, test and build concurrently without conflicts.
Works with Claude Code, Codex, Gemini, Cursor CLI, OpenCode, Copilot, Cline and many other command-line agents using subscriptions you already have.
A built-in browser lets you click any element to copy its HTML, styles and selector, or screenshot a page and drop that context straight into an agent prompt.
Review AI output, run commands and arrange terminals, browsers, files and diffs in panes shaped to the task at hand.

SpecialistAn AI-native code editor optimized for multi-file generation rather than managing multiple parallel terminal agent worktrees.
Provides an extensive platform and desktop command center for parallel AI coding agents, but with a heavier proprietary footprint.
