The terminal is the heart of Pluto Door. Built on xterm.js with GPU-accelerated rendering, it delivers a fast and responsive experience.

• Full xterm.js terminal with 256-color and true-color support.
• GPU-accelerated rendering via WebGL for smooth scrolling and output.
• Customizable font family, size, line height, and cursor style.
• Configurable scrollback buffer (up to 50,000 lines) with fast search (⌘F).
• Integrated file browser and terminal in a split-pane layout.

The built-in AI assistant helps you work faster by understanding your terminal context and suggesting commands. It uses your own OpenAI API key — we never see your prompts.

• Ask questions about Linux commands, server administration, and DevOps.
• The AI can see your recent terminal output for context-aware suggestions.
• Generate complex commands like awk, sed, and find with natural language.
• Explain error messages and suggest fixes.
• Toggle the AI panel with ⌘I or from the sidebar.

The SFTP-powered file browser lets you manage remote files visually. Upload, download, rename, and delete files without typing a single command.

• List view for navigating the remote filesystem.
• Upload and download files with a single click.
• Rename, delete, and create directories inline.
• Open text files directly in the built-in code editor.
• Synced navigation — changing directories in the terminal updates the file browser and vice versa.

Edit remote files directly in Pluto Door's built-in code editor. No need to download, edit locally, and re-upload.

• Syntax highlighting for popular languages (JavaScript, TypeScript, Python, Rust, HTML, CSS, JSON, YAML, Markdown, XML).
• Font ligature support (Fira Code, JetBrains Mono, etc.).
• Configurable font size, line height, and word wrap.
• Save with ⌘S — changes are written back to the server over SFTP.

Pluto Door is highly customizable. Tweak every aspect of the terminal, editor, and app behavior to match your workflow.

• Terminal: font size, cursor style, scrollback lines, bell behavior.
• Editor: font size, font family, ligatures, line height, word wrap.
• General: default SSH port, auto-reconnect, confirm on disconnect.
• AI: OpenAI API key (stored securely in macOS Keychain).
• Data & Privacy: clear chat history, command history, connection statuses, or reset all settings.
• All settings are stored locally. Connection credentials and your OpenAI API key are encrypted in macOS Keychain.

Pluto Door is built with a local-first, zero-trust architecture. Your sensitive data never leaves your machine.

• SSH passwords, license keys, and your OpenAI API key are encrypted in macOS Keychain — the same system-level vault used by Safari, Mail, and other Apple apps.
• Connection details (hostname, port, username) are stored locally in a JSON file on disk. No passwords are ever written to disk unencrypted.
• The AI assistant calls OpenAI directly using your API key. Your prompts and responses never pass through our servers.
• The only network call Pluto Door makes is a one-time license verification on activation. After that, the app works fully offline.
• No analytics, no telemetry, no crash reporting. We literally cannot see what you do in the app.

Pluto Door keeps a history of your connections so you can quickly reconnect to servers you've used before.

• Saved connections shown on the home screen for one-click access.
• Provider auto-detection with badges (AWS, GCP, Azure, DigitalOcean, Hetzner, etc.).
• Status indicators showing last connection result (success/error).
• Label connections with a custom name for easy identification.

Pluto Door is designed to be keyboard-driven. Here are all the shortcuts organized by context.
