wtf is cmdos?

cmdOS is a Chrome browser extension that gives you a keyboard-driven command bar for doing common browser tasks, instead of clicking through menus, bookmarks, and tabs. You press Alt plus S from any webpage to open the command bar, then type or select a command such as opening your notes, creating or opening a saved link, taking a screenshot, or managing keyboard shortcuts. Beyond quick navigation, the extension bundles a set of built-in browser actions you can trigger from the same bar: capturing a screenshot of the visible page or the whole page, downloading images from the current page, extracting a table on the page and exporting it as a CSV file, and generating a print-friendly PDF of the page. The project describes itself as local-first, meaning your notes, links, snippets, and other saved items stay stored on your own machine rather than a remote server, and no account is required to use the core features. Internally it also supports richer object types beyond simple links and notes, including automation workflows, an AI chat agent integration, saved AI prompts, and to-do items, organized as a monorepo with separate packages for UI components, storage helpers, and settings. It is built with React and TypeScript, using Vite and Turborepo for the build system, Tailwind CSS for styling, and pnpm workspaces to manage the project's packages, targeting the Chrome Extension Manifest V3 format. To try it, you clone the repository, install dependencies with pnpm, run the development server, and load the built extension as an unpacked extension in Chrome's developer mode. It is released under the Apache 2.0 license.
