CodexLM is the GPS for your codebase and a NotebookLM-style realtime chat workspace for software projects. It helps developers understand code quickly while Codex is building features in parallel.

The core problem: in fast workflows, repository context becomes stale across chats, branches, and worktrees. Developers lose time validating what changed and where to look. CodexLM solves this with a living, branch-aware docs layer plus source-grounded realtime conversation.

Like NotebookLM, CodexLM is designed for understanding through grounded dialogue. But instead of general documents, it is specialized for codebases. You can ask questions in realtime, and CodexLM answers with evidence from current project sources, then navigates to the exact docs or file context being discussed. Every answer is tied to freshness metadata (branch, commit, indexed time) so users know whether context is current.
