TabCmdr - Command Palette For Your Browser

TabCmdr is a Chrome extension that adds a keyboard-driven command palette to your browser, letting you search and navigate tabs, bookmarks, history, downloads, and recently closed pages from a single input box.

What is TabCmdr?

TabCmdr is a command palette for your browser that replaces the default tab search with a unified interface. You press Ctrl+K and start typing — the extension searches open tabs, bookmarks, history, and recently closed pages, then lets you jump directly to any result. It also includes over 50 built-in commands for tab management, AI chat, utilities, and site-specific shortcuts. TabCmdr runs on Chrome and requires no account or tracking.

Key Features

• Unified search — One input box searches tabs, bookmarks, history, downloads, and recently closed pages as you type; fuzzy matching works across all sources.
• AI chat with your own models — Connect your API key to OpenAI, Gemini, Claude, Perplexity, OpenRouter, Grok, Mistral, or DeepSeek. Type :ai to start a conversation; add @page to give the AI context from the current tab. No data passes through TabCmdr servers.
• Tab management commands — Pin, mute, close duplicates, suspend, sort, or move any tab. Find duplicates and close them in one step.
• Utility tools built into the palette — Emoji picker (fuzzy search across Unicode set), calculator, unit converter, timezone lookup, weather, to‑do list, RSS reader, screenshot tool, QR code generator, and color picker/convertor.
• Site‑specific shortcuts — On YouTube, Gmail, GitHub, Notion, and Figma, TabCmdr shows contextual commands (e.g., player controls on YouTube, mail actions on Gmail).
• Keyboard‑first workflow — All commands are accessible via short codes like :b (bookmarks), :h (history), :ai (AI chat), :todo, :emoji. No mouse required.
• Privacy‑first design — Everything runs locally in your browser. No account, no tracking, no server middleman for AI requests.

Who is it for?

TabCmdr is useful for anyone who works with many browser tabs and wants to stay keyboard‑driven. It fits three primary groups: power users who manage 20+ tabs and frequently bookmark or search history; developers and designers who need quick access to utilities like color pickers, timezone math, or site‑specific commands on GitHub/Figma; and privacy‑conscious users who want a tab manager and AI assistant that never sends data to an external server.

What can you do with TabCmdr?

• Tab‑heavy research sessions — Search hundreds of open tabs and jump to any result without scrolling the tab bar. Close duplicate tabs in one command.
• Cross‑tab AI reasoning — Type :ai @page to ask an AI to summarize or translate the current page, then switch models (e.g., Claude → GPT) without leaving the palette.
• Quick utility access — Compute 20% of 5500, convert 100 km to miles, check time in Tokyo, or grab an emoji — all from the same keystroke, without opening a new tab or app.

How does TabCmdr work?

Install the extension from the Chrome Web Store, then press Ctrl+K (or Cmd+K on Mac) to open the palette. Start typing your query — TabCmdr shows matching tabs, bookmarks, history items, and commands. Select a result with arrow keys and Enter, or type a short code (e.g., :ai, :todo) to open a specific tool. All AI features require you to enter your own API key from a supported provider.
