10 Best ChatGPT Extensions for Chrome in 2026

Typing chat.openai.com into a new tab every time you want to use ChatGPT gets old fast. A good Chrome extension puts AI right in your toolbar, your search results, or your inbox instead. Here are the best ChatGPT extensions for Chrome, grouped by what each one is actually good at.

All-in-One AI Sidebars

These open a panel right in your browser and let you chat, summarize, or ask questions without leaving the page you’re on.

1. Sider AI. Sider gives you a sidebar that works on almost any site and lets you switch between models like GPT, Claude, and Gemini without opening separate tabs. It can summarize the page you’re on, translate text, and pull quotes straight into a chat.
   Best for: people who want more than one AI model without paying for more than one subscription.
2. Merlin. Merlin’s sidebar focuses on comparing answers. Ask one question and see how GPT-4, Claude, and Llama each respond side by side, which is handy when you want a second opinion before trusting an answer.
   Best for: double-checking AI answers across models.
3. Monica. Monica bundles chat, web search, writing help, and basic code assistance into one sidebar, with support for several underlying AI models. It leans toward being a general assistant rather than a single-purpose tool.
   Best for: one extension that tries to cover chat, search, writing, and code.

Search and Browsing Helpers

These extensions plug ChatGPT into the parts of Chrome you already use, instead of adding a brand new tool.

4. ChatGPT for Chrome (Official). This is the extension OpenAI itself publishes. It adds a ChatGPT icon near your address bar, lets you set ChatGPT as your default search engine, and shows source links next to its answers. If you only install one extension on this list, this is the safest pick since it comes straight from OpenAI with no third-party permissions to worry about.
   Best for: anyone who wants the simplest, most official option.
5. ChatGPT for Google. This one runs ChatGPT’s answer alongside your regular Google (or Bing, or DuckDuckGo) results, in a panel next to the search results you already see. It’s a quieter way to get an AI opinion without replacing your search engine entirely.
   Best for: keeping your normal search results and adding AI as a second column, not a replacement.

Productivity and Writing Tools

These are built less for chatting and more for using ChatGPT to get specific tasks done faster.

6. AI Toolbox. Formerly known as ChatGPT Toolbox, this extension adds folders, search, and export options on top of your existing ChatGPT conversation history, plus a saved prompt library. It’s aimed at people who use ChatGPT daily and need to find an old conversation again.
   Best for: power users drowning in old ChatGPT chats.
7. AI Blaze. AI Blaze lets you trigger AI replies, summaries, or rewrites from a keyboard shortcut on almost any website, not just ChatGPT’s own site. Think of it as text expansion with an AI brain attached.
   Best for: firing off quick AI replies without opening a chat window at all.
8. Jetwriter AI. Jetwriter focuses specifically on Gmail and LinkedIn, suggesting context-aware replies based on the message you’re responding to. It can also translate and summarize on the side.
   Best for: people who mostly want AI help inside email and LinkedIn messages.
9. Prompt Genius. This is a free, open-source extension for saving and organizing your own ChatGPT prompts into a searchable library, instead of losing good prompts in old chat threads.
   Best for: anyone who reuses the same handful of prompts constantly and keeps losing them.
10. Compose AI. Compose AI adds AI-powered autocomplete while you type, in Gmail, Google Docs, and most text boxes around the web, suggesting the rest of your sentence as you go.
    Best for: speeding up everyday typing, not running full conversations.

Quick Tips

• You can install more than one of these at once, but having two or three AI icons fighting for space near your address bar gets messy fast. Pick one main tool and uninstall the rest.
• Before installing any of these, check what permissions it’s asking for. An extension that wants to read and change all your data on all websites should at least have a good reason to.
• If you’re not sure where to start, install the official ChatGPT extension first. It’s free, comes straight from OpenAI, and covers most everyday use cases before you go looking for anything fancier.

Most people don’t need five different ChatGPT extensions fighting for space in their toolbar. Start with the official one or a single sidebar tool that matches how you actually work, and only add more if you find a specific gap it doesn’t cover.
