Tabs, status markers, relay badges, and session metadata stay legible without flattening the terminal surface.
Agent-aware accents
Claude, Codex, Gemini, and shell sessions each get distinct visual identity without overwhelming the workspace.
01. AI Agent Support
Claude
Deep reasoning for architectural refactoring, complex debugging, and multi-file changes. Bandwidth-aware mode shows a warm pulse while it works.
Codex
Fast code generation with scrolling terminal feedback. Built for pair programming at speed. Bandwidth-aware mode shows a scrolling terminal while it works.
Gemini
Multimodal context processing with orbiting visual feedback. Great for large-scale analysis. Bandwidth-aware mode shows a orbiting spheres while it works.
Three Streaming Modes
Live (300ms Streaming)
Full terminal output streamed in real-time. Every character appears on your iPhone as it prints on your Mac. Perfect for watching agents work through complex tasks.
Bandwidth Aware
Your iPhone shows a unique animation per agent with a live character counter ticking up. When the agent finishes, the full result is delivered instantly. Minimal data usage.
Silent Mode
The agent runs quietly on your Mac. Only the final output is sent when the session completes. Check results at your convenience — nothing streamed in between.
The iOS Companion
Sign in with your Apple ID on both devices. Same account, same sessions, instant sync.
Watch your agents work in real-time. Send keystrokes back to your Mac from your phone.
See your current branch, uncommitted changes, and recent commits — synced from your Mac on demand.
