An SSH client where the AI can already see the server.
Most AI terminal tools ask you to describe the machine first. Ark starts from the connection you already opened: identity, working directory, services, listening ports, and recent output are part of the agent's context from the first message. It is still a complete SSH and SFTP client when you would rather do the work yourself.
What the "AI" part actually does
An AI SSH client is only useful if the model works from facts rather than guesses. Ark's agent gathers evidence on the server before it proposes anything, and it keeps working toward the goal instead of returning one command and stopping.
- Reads the live server context: the host you are connected to, the identity you are using, the current directory, running services, listening ports, and the output you just saw.
- Follows evidence across steps, so a question like "why does this endpoint return 401" turns into logs, configuration, and one real request rather than a single suggested command.
- Separates what it verified from what it is still unsure about, and says which is which.
- Uses your own model API key, so the provider and the key stay under your control.
What it will not do
The reason to let an agent touch a real server is that the boundaries are clear. These are product behaviours, not settings you have to remember to switch on.
- It does not make a material change without an explicit confirmation from you.
- It does not read your credentials. SSH private keys, passwords, and custom model API keys stay on your device.
- It does not take the terminal away from you. You can stop a run and finish the work in the CLI at any point.
- It does not claim success on execution alone; execution, technical verification, and business health are reported separately.
Still a normal SSH client every day
The agent is the reason to reach for Ark on a hard problem. The terminal is the reason to keep it open the rest of the time.
- TERMINAL
- Shell sessions, splits, history, and completion over one real SSH connection.
- FILES
- SFTP browsing and transfer beside the terminal, with queues you can pause, resume, and retry.
- HOSTS
- Unlimited connected hosts, and import of your existing SSH configuration.
- STATE
- Identity, resources, services, ports, and watch items visible before you decide anything.
