An agent needs your answer. You don’t need your desk.
Answer and keep going.
Open the same session, read the question, and give your next direction.
Pick up where you left off.
Review the changes and continue with the context already there.

Leave the desk.
Keep the context.
Your agents run on your computers. Open their native terminal,
see what is happening, and step in when it matters.

Answer. Then get on with your day.
Your agent needs a decision. Read the question and reply from your phone. Supen handles control when you send.
The right session. Without starting over.
Choose a computer, find your project, and open the work you need. The native terminal and available history keep the work in context.
The keys you need. Within reach.
Reach Esc, Tab, Ctrl-C, and arrow keys without a desktop keyboard. Write your next instruction with the terminal still in view.

Small screen now. More room later.
Check in on your phone, then continue on your tablet or laptop. Your project stays on your computer; your work stays within reach.

What needs my attention?
Two decisions. I’ve gathered the context.
For checkout, the agent can collapse the mobile order summary while keeping the total visible. For search, it’s asking whether to add mixed-case query coverage.
Prepare an update for the team.
Here’s a draft for your review.

A few fair questions
Before you connect.
What can I control about my assistant?
Choose the project context and delegated scope, correct remembered decisions, and pause or end a standing duty. Open the original work whenever you want to inspect or intervene.
Does Supen replace my coding agent?
Your coding agent still runs on your computer. Supen lets you open its session, give direction, and check the work from another device.
What happens when I just open a session?
You can read and scroll without interrupting the agent. Sending a reply or pressing a terminal key gets control for that action; Supen asks first if another device is using it.
What if my connection drops?
Your agent keeps running. Supen keeps your unsent draft. Reconnect, check the latest output, then send when you’re ready.
Do I need a VPN or an open port?
Your computer makes an outgoing connection to Supen. You don’t need to open an inbound port on it or set up a VPN on your phone.
