The core concept of HiTerm is the tmux session — your unit of work. PC and phone are two entry points. Switch anytime, resume anywhere.
Two most common workflows:
- Start on PC, continue on phone — Let your agent run before you leave, review on the go
- Start on phone, continue on PC — Catch an idea on the subway, pick it up at your desk
Scenario 1: Start on PC, Continue on Phone
You're at your PC. An AI agent is writing code or running a build. You need to leave before it finishes.
PC — Create a Named Session, Start the Task
# Create a session with a project name
tmux new -A -s claude-frontend
# Start the AI agent inside the session
claude
The -A flag means: attach if the session exists, create it if it doesn't. Safe to run repeatedly.
Naming matters — the phone identifies sessions by name. Use tool-project format, e.g. gemini-backend, codex-api.
PC — Walk Away
The agent is running. You can leave. The tmux session stays alive regardless of network status or SSH connections.
Phone — Connect After You Leave
- Open the Hi Term app
- Tap your PC in the host list
- You're in the tmux session — see exactly what the agent is doing
Phone — Review Output, Give New Instructions
When the agent finishes, you can:
- Scroll up to see output history
- Double-tap to open the shortcuts panel, tap
Ctrl+Cto interrupt, tap/compactto compress context - Type directly to give the agent new instructions
Phone — Get Notified
If your AI tool has the hiterm notify hook configured (hiterm pair auto-configures Claude Code, Gemini CLI, and Codex), your phone buzzes when the agent finishes. Tap the notification to jump straight back to the session.
Tip: Long tasks survive network drops. Subway tunnels, WiFi-to-4G handoff, even closing the app — the tmux session stays alive on your PC. Just reconnect.
Scenario 2: Start on Phone, Continue on PC
You're on the subway. An idea hits. You want to experiment right now — no need to go back to your desk.
Phone — Create a Session, Start Working
- Open Hi Term, connect to your PC
- Create a new session in the terminal:
tmux new -A -s claude-experiment
- Start working — write code, run commands, launch an AI agent
Everything you do on the phone runs on the PC. The phone is just a screen.
Phone — Put It Down Anytime
Need to get off the train? Just close the app. The session lives on the PC. Nothing is lost.
PC — Back at Your Desk, Pick Up
Open your terminal:
# See what sessions are running
tmux ls
# Attach to the one you created on your phone
tmux new -A -s claude-experiment
The half-written code, running commands, agent conversation — all there. Seamless.
Phone Operations
After connecting to your PC, everything is gesture-based — see Phone Operations.
