Opera is turning its browser sidebar into a proper control center, and the latest update to Opera One is a big step in that direction. With Gemini and Google Translate now built right into the sidebar, the browser is clearly positioning itself as the place where you not only open the web, but also talk to AI, translate text, and juggle multiple tasks without constantly shuffling through tabs.

Earlier this year, Opera rolled out Opera One R3, and this new update builds on that by elevating two services people already rely on every day: Google’s Gemini and Google Translate. Instead of living in yet another pinned tab that gets buried in your “I’ll come back to this later” pile, both now sit in the left-hand sidebar next to Opera’s own AI and other tools. In practice, that means the browser starts to feel less like a window to services and more like a workspace where those services are just native tools.

On the AI side, Opera’s message is simple: use the right model for the right job, without friction. The company has been integrating Google’s Gemini models into its AI features since last year, and now you can pull up Gemini in a column next to whatever you’re working on, instead of opening a dedicated Gemini tab. You get a kind of AI “toolkit” in one place: Opera’s own browser AI, Gemini, and ChatGPT, all a click away in the same strip of UI. For people who like to compare answers between different models—say, drafting a blog post in Gemini, fact-checking with another AI, and then asking Opera’s AI to summarize a page—this setup means fewer clicks and less context lost along the way.

Opera’s AI still leans on multiple underlying models and adds something extra: awareness of the tabs you have open. When you ask it to summarize, rewrite, or brainstorm, it can factor in the content of active pages, sparing you from manually pasting long walls of text. Gemini in the sidebar complements that approach instead of replacing it; you keep Gemini as a dedicated workspace while Opera’s own AI remains the “in-browser” assistant that’s tightly wired into your browsing context.

Translate is getting similar treatment. Opera already offers built-in page translation, which is great when you just want to read a foreign-language article in your own language, but it doesn’t fully solve the opposite scenario: writing back in a language you’re not fluent in. That’s where the Google Translate sidebar comes in. Instead of opening a new tab, copying text, translating, and then copying it again, you hit the Translate icon in the sidebar and type right there, then paste the result wherever you need—say, replying to an Airbnb host, drafting a quick email to a client overseas, or translating a marketplace listing.

The idea is to keep you in flow. You might be reading a French news article with Opera’s full-page translation active, while the Translate panel is open to help you craft a reply or a comment in French without jumping between websites. For people who are constantly interacting across languages—students studying abroad, remote workers on international teams, or just frequent travelers—that one-click access to Google Translate from the browser chrome starts to feel like a must-have rather than a nice extra.

Adding these tools to the sidebar is deliberately low-friction. You open the sidebar setup menu using the three dots at the bottom, scroll to “Google services” for Translate and “AI services” for Gemini, and flip them on; from there, the icons live alongside other sidebar apps like messengers or work tools. This isn’t some hidden flag you have to dig up in a forum thread—it’s part of the mainstream feature set, positioned as something Opera thinks most users will actually want.

Alongside the Gemini and Translate integrations, Opera is also pushing a more ambitious multitasking story. The Split Screen feature that previously let you dock two tabs side by side now goes up to four at once, arranged horizontally, vertically, or in a grid. Consider a typical student setup: lecture video in one tile, notes in Google Docs in another, Gemini answering questions in a third, and a research paper or slides in the fourth—all visible at the same time. For professionals, you can easily imagine spreadsheets, dashboards, tickets, and chat all sharing one monitor; no more Alt-Tab gymnastics every few seconds.

The way you trigger four-way split keeps things familiar. You can drag and drop tabs toward the edges of the window and watch for the layout prompts, or you can multi-select tabs with Ctrl or Cmd, right-click, and choose “Create Split Screen” to arrange them together. Opera is basically borrowing the muscle memory of window management and pulling it inside the browser itself. If most of your work already happens on the web—Docs, Sheets, Notion, Figma, AI tools—this kind of browser-native tiling turns Opera into a sort of lightweight OS for web apps.

There’s a playful side to the update, too. Opera is adding two new dynamic themes, Cybervroom and Mizumi, giving the browser the kind of personality you usually only see in gaming-centric software. Cybervroom leans into a dark, cyberpunk-inspired design with animated visuals, sound effects, and a “vroom-vroom machine” vibe, while Mizumi goes in the opposite direction with a calmer, study-friendly aesthetic available in both dark and light variants. They’re not just color schemes; they bring animations, keyboard sounds, and background audio, as if the browser wants to match the mood of the work you’re doing.

Taken together, this update is part of a broader strategy Opera has been developing for a while: turning the browser into an AI-forward productivity hub rather than a passive window to sites. Last year’s partnership expansion with Google brought Gemini deeper into Opera’s AI features, and now the Gemini sidebar panel is the logical next step—putting Google’s models on equal footing with Opera’s own assistant and other third-party tools like ChatGPT. For users, the brand behind the AI becomes less important than the fact that everything is reachable in one or two clicks, with contextual awareness built in when you need it.
