Chrome extension built by Pavo as a long-running side project. When the matching gem is added to a Rails application, the extension exposes per-request breakdowns: response speed, parameters, headers (with filtering), local variables, custom metadata, Active Record queries (inspection, re-execution, result viewing, AI-assisted Q&A on a specific query with optional execute), a Ruby console that evaluates code in the running app instance, prepared script snippets that auto-detect object attributes, and an in-browser editor that lets you modify views live (e.g. change a button's color in a Vite-powered UI). Also includes a notes / to-do list feature.
