Pantheon AI

The AI coding assistant that routes every question to the best available model — and streams the answer directly inside VS Code.

No tab-switching. No copy-pasting. Select code, ask a question, get a streamed answer beside your editor in under a second. Pantheon maintains full conversation history within the session so follow-up questions always have context.

Features

• Persistent chat panel — opens beside your active editor, stays there, never interrupts your flow
• Real-time streaming — responses stream token-by-token with a live cursor; no waiting for the full reply
• Context-aware selection commands — highlight any code block and send it directly to the panel with one command or right-click
• Explain and Fix shortcuts — dedicated commands that pre-fill the prompt with your selected code; no manual wrapping needed
• Full conversation history — every message in the session is sent as context, so follow-up questions work naturally
• Secure key storage — API key is stored via VS Code's SecretStorage API (encrypted, OS keychain-backed) and never written to settings files or logs
• Theme-aware UI — the panel inherits your VS Code color theme (light, dark, high contrast) automatically

Getting Started

1. Install the extension

Search for Pantheon AI in the Extensions panel (Ctrl+Shift+X) and click Install. Or install from a .vsix file via Extensions: Install from VSIX... in the Command Palette.

2. Set your API key

Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P) and run:

Pantheon: Set API Key

Paste your key (pk_live_...) and press Enter. The key is saved securely using VS Code's built-in SecretStorage and is never written to settings files or logs.

Get your key at getbased.dev → Settings → API Keys

3. Open the chat panel

Press Ctrl+Alt+P (Windows/Linux) or Cmd+Alt+P (Mac), or run Pantheon: Ask AI from the Command Palette. The panel opens beside your active editor.

You're ready. Ask anything.

Commands

All commands are available from the Command Palette (Ctrl+Shift+P / Cmd+Shift+P). The three selection commands also appear in the right-click context menu when text is selected in the editor.

Configuration

Configure via the Settings UI (search Pantheon) or directly in settings.json:

{
  "pantheon.apiKey": "pk_live_your_key_here",
  "pantheon.apiUrl": "https://pantheon-api.vercel.app"
}
