Opera One
Opera's free everyday browser with a built-in AI sidebar that reads your tabs.
3.9our rating
Free
Quick take
- A free Chrome-style browser with Opera AI in the corner. It reads the page or a group of tabs and answers questions, summarises and compares.
- It's free, with no account needed. Signing in to a free Opera account only raises the daily image limit.
- It's an assistant, not an agent. It won't click through sites or fill in forms for you; for that, look at Comet or Opera Neon.
- Page access is off until you allow it, but what you share goes to Opera and Google.
What is Opera One?
Opera One is the main desktop browser from Opera, the Norwegian company that has made browsers since the 1990s. It runs on the same engine as Chrome, so Chrome extensions work, and it comes with a free VPN, an ad blocker, WhatsApp and Messenger in the sidebar, and Tab Islands, which group related tabs together and let you name and colour them. Its AI assistant, called Aria until early 2026 and now just Opera AI, sits behind an Ask AI button in the top corner and runs on Google's Gemini models.
Day to day, Opera AI answers questions about the page you're on or a whole Tab Island, summarises articles and YouTube videos, compares the pages in a group, reads files you upload, translates, drafts text and makes images. It's free and works without signing in. What it doesn't do is click through websites for you. Opera added a Browser Connector in April 2026 that lets ChatGPT or Claude read your open tabs, but it was still an opt-in test feature and can't fill in forms. Pick Opera One if you want a free, polished browser with a handy AI sidebar and lots of built-in extras; pick Comet if you want an agent that can do tasks on websites; pick Opera Neon if you'll pay for Opera's agent.
The catch is that Opera AI is a helper, not an agent, and Opera doesn't publish usage limits or say exactly which Gemini model you get. Page access is off until you allow it and the AI doesn't see your history, but anything you share goes to Opera's servers and its model partners, so keep it off banking and medical sites as Opera itself advises. The browser also shows sponsored speed dials and news by default.

How it fits your tech stack
Opera One replaces Chrome or Edge rather than sitting beside them, and your extensions and bookmarks come across. If you already pay for ChatGPT or Claude, the Browser Connector lets them see your tabs. For an AI that does tasks on websites, Comet (free) or Opera Neon (paid) go further.
