OpenAI adds ChatGPT sidebar and cross-tab help to Chrome

OpenAI's upgraded Chrome extension adds a ChatGPT sidebar that reads across tabs and, via ChatGPT Work, acts on websites.

To use it, Chrome users install the official ChatGPT extension from the Chrome Web Store and sign in. The sidebar then appears alongside webpages; after permissions are granted, it can use information from open tabs. More advanced website actions are available through ChatGPT Work, depending on the account’s access.

TechRadar described the main appeal as familiarity. Existing ChatGPT users can ask questions about what they are reading without copying text into a separate conversation. With several articles open on the same announcement, for example, the assistant can compare coverage, point out discrepancies or explain unclear points. For shopping, it can examine product pages across retailers and help organize specifications and pricing, though TechRadar said prices and important details still need verification.

The review said the sidebar makes smaller interactions more natural because it is essentially the same ChatGPT experience connected to current browsing. OpenAI does not have to teach users a new assistant or workflow; it makes an existing tool more accessible. But TechRadar cautioned that reading webpages does not guarantee correct interpretation, especially when sites have unusual formatting or hide information behind interactive elements. It said a confident summary should not replace checking the source when accuracy matters.

ChatGPT Work goes further by carrying out tasks rather than only answering questions. In one experiment, a TechRadar reviewer opened a registration page for a free technology webinar and asked ChatGPT Work to fill out the form, with instructions to stop before submitting. The assistant paused to ask for clarification when choosing an industry category, and the reviewer said final human review remained essential because even a small error in a registration form can be more troublesome than filling it out manually.

TechRadar said supervision matters when an AI can interact with websites where a user is already signed in. Giving ChatGPT access to information across tabs also requires users to consider what those tabs contain and which sites the assistant is authorized to use. OpenAI includes permission controls, but users still need to judge what they allow an AI agent to access.

The upgrade places ChatGPT more directly in competition with Google’s Gemini inside Chrome. Google controls the browser and has been working to make Gemini a more prominent part of it, giving its own assistant a natural advantage in the world’s most popular browser. OpenAI’s move is intended to keep Chrome users relying on ChatGPT even while they browse inside Google’s ecosystem, according to TechRadar.
