Tilburg.ai

Tilburg University's AI assistant for VS Code: a chat panel and inline code completions, both backed by tilburg.ai's OpenAI-compatible API.

Features

• Chat — ask questions from a dedicated panel in the Activity Bar, with Markdown rendering, code blocks with a Copy button, and a model picker.
• Inline code completions — ghost-text suggestions as you type, in any language. Toggle, disable, or snooze them from the Tilburg.ai status bar item in the bottom right (click it for the menu), just like GitHub Copilot's status icon.
• Model selection — switch between the models configured in config.yaml via the "Tilly: Select Model" command or the toolbar dropdown.

Getting started

1. Install the extension.
2. Run Tilly: Set API Key (Command Palette, or the button in the Tilly panel) and enter your tilburg.ai API key. It's stored in VS Code's Secret Storage — never written to a file or synced anywhere else.
3. Open the Tilly panel from the Activity Bar to start chatting, or just start typing in any file to see inline completions.

Configuration

Model settings live in config.yaml. Drop a config.yaml in your workspace root to override the bundled default; each model entry's roles array controls what it's used for:

models:
  - name: Tilburg gpt-5.4-nano
    provider: openai
    model: gpt-5.4-nano
    apiBase: https://api.tilburg.ai/v1
    roles: [chat, edit, apply, autocomplete]

Relevant VS Code settings:

• tilly.model — which model (by id) the chat panel uses.
• tilly.completionsEnabled — turn inline completions on/off (also toggled from the status bar menu).

Privacy

Chat messages and, for inline completions, the code surrounding your cursor are sent to the tilburg.ai API (configured via apiBase above) to generate responses. No code or conversation content is sent anywhere else, and nothing is retained locally beyond the current VS Code session.

Commands

Requirements

VS Code 1.86 or later. A tilburg.ai account and API key.
