Google Apps Script Copilo

Write Google Apps Script faster — without ever leaving the editor.

Google Apps Script Copilot embeds a full AI coding assistant directly inside script.google.com. No tab-switching, no copy-pasting from chatbots. You get context-aware help grounded in your actual open project — right where you write code.

✨ FEATURES

💬 AI Chat
Ask anything about your project. Debug errors, understand Google Workspace APIs, and generate code in a chat panel that already knows your open files.

🤖 Agent Mode
Describe the change you want. The agent explores your project (read, grep, lint), plans the edit, and applies changes across multiple files — automatically.

📋 Plan Mode
For bigger tasks, the AI writes a step-by-step plan and asks clarifying questions before touching a single line of code.

⌨️ Inline Completions
Ghost-text suggestions as you type, tuned for Apps Script and the Google Workspace APIs — Sheets, Docs, Gmail, Drive, Calendar, and more.

✏️ Quick Edit
Select any code, describe your change, and apply a refactor, fix, or rewrite — without leaving the editor.

🔌 MCP Support
Connect Model Context Protocol (MCP) servers to give the assistant access to extra tools, data sources, or your own Workspace data.

🧑‍💻 Sub Agents
For complex tasks, specialized AI helpers automatically assist with review, debugging, refactoring, docs, or research while the main assistant coordinates.

↔️ Diff Review & One-Click Revert
Every AI change appears as a clear diff you review and approve. Any turn can be undone in one click.

@ Mention Files
Pull any file in your project into the conversation with @filename — the AI answers with full context.

➕ Add to Chat
Send any selection into the chat instantly. When the editor flags an error, an "Add to Chat" action appears right on it — so the AI can fix it in one click.

🧠 Skills
Use specialized slash-command skills for real Apps Script workflows: Add-on, Code Review, Frontend Design, Web App, Library, Sheets Expert, Optimize, Debug, Triggers, API Integration, and Explain.

🌍 Multi-Lingual Support
Use the extension in English, Deutsch, Español, Français, Italiano, 日本語, Русский, and 简体中文. The assistant can also respond in your selected language while staying grounded in your open Apps Script project.

✨ Prompt Enhancer
Turn a rough one-liner into a detailed, well-structured prompt with a single click.

🎨 Light & Dark Themes
Automatically matches the Apps Script editor's appearance.

🔑 BRING YOUR OWN KEY (BYOK)

Connect your own API key for OpenAI, Anthropic (Claude), Google Gemini, or OpenRouter — then choose exactly which model you want to run. Full control, no lock-in.

🔒 PRIVACY & PERMISSIONS

The extension runs only on the Google Apps Script editor. Your code is sent to the AI provider you choose solely to generate the assistance you requested — nothing else is stored or shared.
