Free AI Agent No VPN
OpenCode — The Best Free AI Agent to Start With (No VPN Needed)
If you want to try an AI Agent without paying, without a VPN, and without a steep learning curve — start with OpenCode.
What is OpenCode?
OpenCode is an open-source AI coding assistant that can do far more than just write code. Think of it as an AI helper that works inside a folder on your computer — it can read files, write files, browse the web, and connect to tools like NotebookLM via MCP.
Why for Hong Kong teachers?
- ✅ Completely free — no monthly fees, no API credit to buy
- ✅ No VPN needed — use the built-in Minimax M2.5 model directly from Hong Kong
- ✅ Desktop app available — graphical interface, no command-line required
- ✅ MCP support — connect to NotebookLM, Google Drive, and more
- ✅ Safe — only works within the folder you give it
What Hong Kong teachers can do with it
1. News → Worksheet
Drop in a news article and ask for a worksheet:
You: "Turn this article about inflation into an Economics worksheet, bilingual (English + Chinese), MC and short answers, with answer key"
2. PDF → Study Notes (via NotebookLM)
You: "Import each PDF in this folder into NotebookLM, generate study notes, save the output as markdown files back in this folder"
3. Interactive answer-checking pages
You: "Create an interactive webpage for this fill-in-the-blank worksheet where students click to reveal answers"
How to get started
- Download the Desktop App from the OpenCode website
- Create a workspace folder — all the Agent's work stays here
- Pick Minimax M2.5 as the model (free, no VPN)
- Start prompting — just tell it what you need
