    Opera is known for its fast browsing experience due to its optimized browsing engine and efficient resource management.
  • Built-in VPN
    Opera includes a free, unlimited VPN service, providing users with increased privacy and security by masking their IP addresses.
  • Battery Saver
    The browser features a battery saver mode that extends the battery life of laptops by reducing the browser's power consumption.
  • Ad Blocker
    Opera has an integrated ad blocker that enhances browsing speed and user experience by blocking intrusive ads.
  • Customizable Interface
    Users can personalize their browsing experience with a variety of themes and workspace options to suit their preferences.

Possible disadvantages of Opera

  • Market Share
    Opera has a smaller user base compared to other major browsers like Chrome and Firefox, which can lead to less community support and fewer extensions.
  • Extension Support
    Though Opera supports Chrome extensions, the overall availability and variety of native Opera extensions are limited compared to its competitors.
  • Sync Issues
    Some users have reported occasional problems with syncing data across devices, which can be inconvenient for those who rely on seamless access to their bookmarks and settings.
  • Compatibility
    Certain websites and web applications may not be fully optimized for Opera, potentially leading to compatibility issues.
  • Privacy Concerns
    Despite its built-in VPN, some users are cautious about Opera's privacy policies, especially given its ownership by a Chinese consortium.

Kuse features and specs

  • AI workflows
    Tell Kuse what you do every day. It builds the system, runs it on schedule, and saves every result to your workspace. No nodes. No maintenance.
  • Content Creation
    Tell Kuse what you need and point it at your templates, data, or reference files. It produces polished, structured output in seconds, not hours.
  • File System
    Most AI tools forget everything the moment you close the chat. Kuse stores your work in a persistent, cloud-based file system that every future conversation can reference, search, and build on. Access it from any browser, nothing to install.
  • Integrations
    Kuse works with 70+ tools out of the box. Connect once, automate everything.

Questions & Answers

As answered by people managing Opera and Kuse.

Why should a person choose your product over its competitors?

Kuse's answer:

People should choose Kuse when they want outcomes, not just conversations.

Compared with chatbots, Kuse is better for producing ready-to-use work across multiple formats. Compared with automation tools like Zapier or n8n, Kuse is more natural-language driven and built for knowledge work, not only app-to-app triggers. Compared with narrow AI tools for slides, docs or websites, Kuse gives users one workspace where they can create, organize, convert and reuse work across formats.

The core advantage is simple: you describe the goal, Kuse plans the work, uses relevant context and tools, then gives you something you can actually use.

Which are the primary technologies used for building your product?

Kuse's answer:

Kuse is built with a modern web and AI stack, including:

โ€ข Next.js and React for the web application โ€ข Zustand for state management โ€ข Radix UI, Framer Motion and a custom design system for the interface โ€ข Tiptap and ProseMirror for rich text editing โ€ข Konva.js and Pixi.js for canvas and visual workspace experiences โ€ข SSE streaming and multi-model AI support for real-time AI interactions โ€ข dnd-kit for drag-and-drop interactions โ€ข Lingui for internationalization โ€ข Sentry and Mixpanel for monitoring and analytics โ€ข Stripe and a credit system for monetization

How would you describe the primary audience of your product?

Kuse's answer:

Kuse is built for ambitious individuals and small teams who need to produce high-quality work quickly but do not have enough time, staff or operational bandwidth.

The strongest audience includes founders, marketers, creators, consultants, operators, students and solo professionals who constantly need to turn scattered information into polished outputs, such as research, websites, reports, decks, spreadsheets and recurring business workflows.

Who are some of the biggest customers of your product?

Kuse's answer:

โ€ข Meta โ€ข Shopee โ€ข KPMG โ€ข Deloitte โ€ข Alibaba.com โ€ข ByteDance โ€ข Tencent โ€ข Yandex

What makes your product unique?

Kuse's answer:

Kuse is not just another AI chat tool. It is an AI workspace that turns messy inputs, files, links, ideas and recurring tasks into finished work.

Most AI tools stop at an answer. Kuse helps users create actual deliverables, such as docs, slides, websites, sheets, reports and workflows. It also keeps the work inside a workspace, so users can continue editing, asking questions, reusing context and turning one-off tasks into repeatable workflows.

What's the story behind your product?

Kuse's answer:

Kuse started from a simple belief: AI should not only answer questions, it should help people complete real work.

Modern work is messy. People collect ideas, files, tabs, notes, customer inputs and meeting context across many tools, then spend hours turning that chaos into something clear. Kuse was created to close that gap. Its mission is to help people move from raw ideas to ready work, using AI as a coworker that can understand goals, organize context and produce deliverables.

The bigger vision is that AI will change how work is organized. Instead of people manually coordinating every task across tools, AI will help route information, execute workflows and reduce coordination cost.

Opera mentions (23)

  • Can anyone tell what is this?
    This is not opera.com it's "api2 dot com" so it's a malware site posing as an opera one by including opera in its name. I had a popup like this. It opened every time I opened the browser. Turned out it was coming from a video downloader extension. Source: about 3 years ago
  • Is there a way to download the official browser through a torrent or a mirror link?
    The opera.com domain is banned where I live but I still want to download the browser without a VPN (because those are also banned). Is there a torrent link or an alternative/mirror link where I can download the latest Opera One release? Thanks! Source: about 3 years ago
  • Opera Adblocker pinging opera.com?
    Apparently it "urgently needed to be removed off the network" (bullshit, you could've blocked opera.com, dumbass) I don't see why its so bad to have one kid with an unmanaged browser, like seeing "your browser is managed by your organisation" sucks enough. They disabled basically everything good about Chrome, for a time, they locked down the performance tab so we couldn't even use battery saver. Source: about 3 years ago
  • Opera Adblocker pinging opera.com?
    One day, I got called to my Deputy Principal's (Dep. For short) office because my laptop was doing wacky shit to the network. He informs me that my laptop had sent 64k pings to opera.com. It was about the 2nd term, we receive new laptops every couple of years. He first told me about my searches for a VPN, which I guess is on me. But when he brings up the 64k pings, he tells me whatever the app is doing it has to... Source: about 3 years ago
