⚡ The Power of Antigravity + NotebookLM

Normally, AI coding agents struggle when working with massive, complex codebases or hyper-specific documentation because of token limit constraints and search inaccuracies.

By using the NotebookLM MCP Server (notebooklm-mcp-cli), you can upload thousands of pages of documentation, textbooks, papers, or legacy repositories into a NotebookLM notebook, and expose that highly structured, semantic knowledge directly to Antigravity CLI.

NotebookLM acts as the expert researcher that understands the domain perfectly.
Antigravity acts as the expert engineer that writes, refactors, and deploys the code on your local system.

Let's dive into the 50 project ideas!
