Review AI-generated code in VS Code using free AI chats, no API keys required
I've been experimenting with reviewing AI-generated code using a second model without spending additional coding-agent tokens or paying for API calls.
I built AI Badger, a free, open-source VS Code extension that packages your Git changes into a review prompt you can paste into ChatGPT, Claude, Grok, or another browser-based AI chat.
You can use free chat tiers or an existing subscription. No API key or separate AI service is required. Your normal chat usage limits still apply, but you're not consuming your coding agent's quota.

For more complex reviews, it also supports an iterative workflow where the reviewer can request additional repository context instead of guessing from the diff.

I'm curious whether others use separate AI chats for code review or stick with their coding agent's built-in review tools.
