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 in VS Code's global settings via the built-in secrets mechanism and never logged
- Theme-aware UI — the panel inherits your VS Code color theme (light, dark, high contrast) automatically
