The best ChatGPT extensions for Chrome put AI right next to the page you’re reading, so you stop copying text into another tab. If you only install one, make it OpenAI’s own ChatGPT extension. It’s free and it comes straight from the company that makes ChatGPT. The rest of this list covers sidebars that mix several AI models, prompt libraries, and writing helpers for Gmail and LinkedIn.
Which ChatGPT extensions for Chrome come from OpenAI?
OpenAI makes two. They sound alike, but they do different jobs.
- ChatGPT (official). This adds a side chat next to the page. You can ask about the page, highlight text and choose Ask ChatGPT, or ask about your other open tabs. Paired with the ChatGPT desktop app, it can also do tasks in Chrome for you.
Best for: anyone who wants ChatGPT in Chrome with no third party in the middle. Our official ChatGPT Chrome extension guide walks through setup. - ChatGPT search (official). This one does a single thing. It makes ChatGPT the search engine in your address bar, so your searches go to ChatGPT instead of Google.
Best for: people who want AI answers every time they search, and nothing else.
Which AI sidebars work with more than one model?
These open a panel in your browser and let you switch between ChatGPT and other AI models. That way, you don’t need a separate subscription for each one.
- Sider AI. Sider’s sidebar works on almost any site. You can switch between GPT, Claude, and Gemini models, summarize the page, and translate text without leaving it.
Best for: trying several AI models from one place. - Merlin. Merlin is built for research and comparing answers. Ask one question and see how different models respond. That’s handy when you want a second opinion before you trust an answer.
Best for: double-checking AI answers. - Monica. Monica puts chat, web search, writing help, and simple code help into one sidebar. It’s a general assistant rather than a single-job tool.
Best for: one extension that covers a bit of everything.
Which extensions help you manage ChatGPT chats and prompts?
- AI Toolbox. Once called ChatGPT Toolbox, it adds folders, search, and export to your ChatGPT chat history. It also has a saved prompt library.
Best for: daily users who keep losing old chats. - AI Prompt Genius. This free, open-source extension saves your favorite prompts in a library you can search. Then you can reuse them in one click.
Best for: anyone who types the same few prompts over and over.
Which ChatGPT extensions help you write faster?
- AI Blaze. AI Blaze runs AI replies, summaries, and rewrites from a keyboard shortcut on almost any website. Think of it as text shortcuts with AI behind them.
Best for: quick replies without opening a chat window. - Jetwriter AI. Jetwriter works inside Gmail and LinkedIn. It suggests replies based on the message you’re answering, and it can translate and summarize too.
Best for: AI help in email and LinkedIn messages. - Compose AI. Compose AI adds autocomplete as you type in Gmail, Google Docs, and most text boxes. Press Tab to accept a suggestion.
Best for: speeding up everyday typing, not long chats.
How do I pick a safe ChatGPT extension?
Fake ChatGPT extensions are a real problem. In early 2026, security researchers found copycat extensions that stole people’s chats and passwords. So before you click Add to Chrome, run through these checks:
- Check who offers it. The official ones say OpenAI. For anything else, look for a real company name and website.
- Read the permissions. An AI sidebar needs to read pages, but a prompt saver shouldn’t need access to every site.
- Keep it to one or two. Each extra AI tool is one more company that can see what you browse.
Google explains how to check an extension’s permissions on its Chrome Web Store help page.
Frequently asked questions
Is there an official ChatGPT extension for Chrome?
Yes, two. OpenAI publishes ChatGPT, which adds a side chat, and ChatGPT search, which makes ChatGPT your search engine. Both are free.
Are ChatGPT extensions for Chrome free?
Most are free to install. However, many third-party ones limit how much you can use them unless you pay, so check the listing before you rely on one.
Can I use more than one at a time?
You can, but two or three AI icons in your toolbar gets messy fast. Pick one main tool and remove the rest.
The short version
Start with OpenAI’s ChatGPT extension. Add a multi-model sidebar like Sider or Merlin only if you want other AI models too, and add a writing tool only if you write a lot in Gmail or LinkedIn.
