ChatGPT, Claude, Gemini Chrome Extensions & Shortcuts: The Complete Guide to Doubling Your Work Speed

Introduction: Why AI Tool Setup Determines Your Work Speed

Most office workers open a new browser tab and type in the URL every time they use ChatGPT, Claude, or Gemini. That adds up to an average of 37+ unnecessary clicks and tab switches a day.

Follow this guide to the end and you will have an environment where you can launch all three AI tools without taking your hands off the keyboard.

Step 1: Install Chrome Extensions — Put the Big Three AI Tools in Your Browser

1-1. Install the ChatGPT extension

1. Open the Chrome browser

2. Type chrome.google.com/webstore in the address bar and press Enter

3. Type **"ChatGPT for Google"** in the search box at the top left

4. Find "ChatGPT for Google" (developer: chatgpt4google.com) in the results — it has a blue robot icon

5. Click the blue [Add to Chrome] button

6. When the pop-up appears, click **[Add extension]**

7. Next, search for **"OpenAI ChatGPT sidebar"**

8. Install the "Sider - ChatGPT Sidebar" extension the same way

💡 Once Sider is installed, you can open ChatGPT in the right-hand sidebar on any web page. You can ask for a summary right while reading an email.

1-2. Install the Claude extension

Claude has no separate official Chrome extension, but you can get the same effect with the following method.

1. Search the Chrome Web Store for **"Claude.ai Quick Access"**

2. Or search for **"Webapp Launcher"** and install it

3. After installing, click the **puzzle-piece icon (Extensions)** at the right of the address bar

4. Click the pin icon next to Webapp Launcher to pin it to the toolbar

5. Click the Webapp Launcher icon and select **[Add Webapp]**

6. Enter https://claude.ai as the URL and name it **"Claude"**

7. Click **[Save]**

Now one click in the toolbar opens Claude in a new tab.

💡 Claude has had a desktop app since 2025, so we recommend the desktop app plus a keyboard shortcut over the extension. We cover this in Step 2.

1-3. Install the Gemini Extension

1. Search for **"Google Gemini Side Panel"** in the Chrome Web Store

2. Find the official "Gemini - Google AI Assistant" extension — make sure the developer is Google LLC

3. Click [Add to Chrome] → **[Add extension]**

4. Once installed, a Gemini star icon appears at the top right of Chrome

5. Click the icon to open Gemini in a side panel

One more extension we strongly recommend:

1. Search for **"Google Gemini Nano"** in the Web Store

2. Enter chrome://flags in Chrome's address bar

3. Type **"Gemini Nano"** in the search box

4. Set "Enables optimization guide on device" to Enabled

5. Restart Chrome

💡 With Gemini Nano enabled, you can do simple text summaries and translation without an internet connection. That means you can use AI even on a plane.

1-4. Installation Checklist

1. Enter chrome://extensions in the address bar

2. Confirm that all of the following extensions are enabled (blue toggle ON):

5-3. Market Research Report Draft (Gemini — invoke with Ctrl + Alt + G)

Please draft a research report on the 2025 Korean B2B SaaS market using the following structure.

1. Market size and growth rate (including the latest figures)

2. Three key trends

3. Competitive landscape (comparison table of 5 major players)

4. Opportunity areas for our company (cloud inventory management) to enter

5. Source URLs

Please reflect the latest information based on Google search results.

💡 Gemini comes with Google Search built in, making it the best fit for research that needs up-to-date figures. Claude excels at analyzing long documents, and ChatGPT at creative writing. Build the habit of using shortcuts to call different AIs depending on the task.

Step 6: Set Up Auto-Start — Create an Environment Where AI Is Ready When You Turn On Your PC

6-1. Register Auto-Start on Windows

1. Press Win + R

2. Type shell:startup and press Enter

3. Copy shortcuts for the following apps into the Startup folder that opens:

   • ChatGPT desktop app (path: C:\Users\[username]\AppData\Local\Programs\ChatGPT\ChatGPT.exe)

   • Claude desktop app

4. Close the folder

6-2. Register Auto-Start on Mac

1. Open Apple menu → System Settings → General → Login Items

2. Click the [+] button

3. From the application list, add ChatGPT and Claude one at a time

Before/After:

• Before: Boot PC → open Chrome → click ChatGPT in bookmarks → wait for loading → start using (about 45 seconds)

• After: Boot PC → already waiting in the tray → Alt + Space to use instantly (about 2 seconds)

Step 7: Prevent Extension Conflicts & Optimize Performance

Installing multiple extensions at the same time can cause conflicts.

7-1. Manage Extensions in Groups

1. Search for **“Extension Manager”** in the Chrome Web Store and install it

2. Click the extension icon and create a group:

   • "AI Work" group: ChatGPT for Google, Sider, Gemini Side Panel

   • "General Work" group: the extensions you already use

3. You can switch each group ON or OFF depending on the situation

7-2. Managing Memory

AI extensions use a lot of memory:

1. On chrome://extensions, click **[Details]** for each extension

2. Change "Site access" to **"On click"** (instead of always running)

3. This cuts memory usage by about 40%

💡 If your PC has 8GB of RAM or less, enable only one of Sider or Gemini Side Panel. Both are sidebar tools, so their features overlap.

Scenario A: Writing a Sales Proposal
