Let the server
speak for itself.
Ark is an AI-native terminal and SSH client for remote servers. CLI, SFTP file transfer, server state, and Agent share one real connection. State the goal; it gathers evidence on the server, moves the work forward, and returns the result for your confirmation.

Work in the field
A typical AI waits for you to explain the background. Ark starts from the server you already connected: identity, directories, services, ports, and recent output share one context.
01IdentityHost, user, OS, and current directory
02Live stateServices, ports, and what needs attention
03Recent outputThe terminal facts already on this connection
04Agent starts hereNo pasted background. Same server, one context.

The model understands the goal. Harness connects the current environment, uses the tools, and leaves a traceable record of each run.

Trust is more than saying “secure.” Before and after every change, you should know what Ark is doing and whether the result actually holds.

See the operation first
Server, identity, target, full command, expected impact, and verification method.

Each confirmation authorizes only the explicit operation in front of you.

Separate execution success, technical verification, and business health.

SSH keys and passwords stay on your device; custom model API keys are used only with the endpoint you configure and are not uploaded to Ark.

07 / FAQ
Questions before you connect
Is Ark an SSH client or an AI assistant?
Both. Ark is a complete SSH client and terminal you can use on its own, plus an Agent that works from the server you already connected. Nothing requires you to use the Agent.
Which platforms does Ark support?
macOS 12 or later on Apple Silicon and Intel, and Windows x64. We publish a signed installer for each system. macOS is also on the Mac App Store outside mainland China. Pro includes an iOS companion that pairs over the local network and is available on the App Store. An Android companion is in development.
Can I use Ark without the AI features?
Yes. The Free plan covers SSH and CLI sessions, SFTP file transfer, unlimited connected hosts, local history, and multi-device sign-in without cloud sync.
Does Ark handle SFTP file transfer?
Yes. You browse and transfer files next to the terminal instead of switching to a separate app, and transfer queues can be paused, resumed, and retried.
Where do my SSH keys and passwords live?
On your device. SSH private keys and passwords stay on your device. Your custom model API key is sent only as needed to the model endpoint you configure; it is not uploaded to Ark. Local-network pairing copies them between your devices and does not go through Ark's cloud.
Can Ark reuse my existing SSH config?
Yes. Ark imports host settings from your existing SSH configuration, so you do not re-enter addresses, users, and authentication details.
Which AI models does Ark use?
You bring your own API key. Basic lets you configure custom models, so the provider and the key stay under your control.
Which AI API protocols does Ark support?
Currently only the OpenAI-compatible API. More protocols are rolling out; stay tuned.
Does Ark support Ollama and other locally hosted models?
Yes. Ollama also speaks the OpenAI-compatible API, so it works the same way. See the Ollama website for installation.
How much does Ark cost?
Free is $0. Basic is $1.99 per month and Pro is $4.99 per month. Accounts registered by November 30, 2026 receive Basic access through the promotional period. The promotion does not auto-renew or charge you; without a paid subscription, the account returns to Free when it ends.
How do subscriptions and cancellation work?
Paid plans are monthly and auto-renew until you cancel. You can cancel anytime; the current period stays active, then the account returns to Free. Website and direct-download purchases go through Stripe. The Mac App Store version follows Apple’s subscription rules and shows store prices. Model usage is billed by your provider.
