夸克 - Quark
Guangzhou Dongyue Information Technology Co., Ltd. (Alibaba Group) · AI Assistant · China AI
Quark is an AI search app and browser from Alibaba that puts a large language model behind everyday tasks. It blends a Qwen-powered assistant with web search, a personal cloud drive, a document scanner, and a video player, so you can pull up an answer, store a file, or convert a scan without hopping between apps. It's built for people who want quick, structured answers and a tidy place to keep what they find. Most of its strengths assume a comfort with Chinese-language apps.
About 夸克 - Quark
What Is Quark
Quark started life in 2016 as a lightweight web browser incubated inside Alibaba, and it grew into a search platform with more than 200 million users in China. In March 2025 the company rebuilt it around its own Qwen reasoning model, turning the browser into what Alibaba calls a flagship AI app.
The pitch is consolidation. Instead of one app for search, another for cloud storage, and a third for scanning documents, Quark folds all three into a single interface. The assistant handles multi-step questions, drafts documents, generates images, and summarizes files you upload. Search, storage, and editing sit beside it.
The catch is language and reach. The interface and much of the content lean heavily Chinese, and some features tie into services that work best inside China. If you don't read Chinese, you'll spend real time working around that.
Getting Started
- Download the Quark app from your phone's store, or open the web version at quark.cn in a desktop browser.
- Create an account and sign in. An Alibaba-linked account lets your bookmarks, history, and cloud files sync across devices.
- Type a question into the AI box, or tap the camera icon to search with a photo instead.
- Upload a document or scan to summarize it, translate it, or convert it to an editable format.
- Save anything worth keeping to the cloud drive so it stays reachable from every device you use.

Key features
AI Search With Structured Answers
Quark's search box returns more than links. Ask a question in plain language and the assistant pulls together a summary, breaks down steps, and lays out supporting points in a readable format. It handles follow-up questions in the same thread, so a broad query can turn into a focused conversation without you retyping context.
The Qwen-Powered Assistant
The assistant runs on Alibaba's Qwen model, which handles reasoning, drafting, and calculation. It writes in several styles, from formal reports to social posts, and adapts tone on request. It also takes voice and photo input. Talk through a problem, or snap a page and ask about it.
Cloud Storage and Sync
The built-in drive gives paid users up to 6 TB of space and keeps files in step across phone, tablet, and desktop. Uploads and downloads aren't throttled, large-file transfers are supported, and video streams without a wait. Free users get far less. Heavy storage use pushes you toward a subscription.
Document and Scan Tools
The scanner captures text and tables from paper, then converts them into editable Word, Excel, or PDF files. It recognizes writing in images, extracts tables, and strips handwriting from homework photos. According to the developer, layout, fonts, and colors are preserved during conversion. That matters when reformatting a contract or form.
Built-In Translation
Translation runs across text, images, and uploaded documents, covering more than a dozen languages. It produces side-by-side layouts for documents and lets you read foreign web pages without leaving the browser. Handy when you're researching across languages.
Video Player With AI Subtitles
Quark includes a player that handles common formats, supports playback from 0.5x to 5x speed, and generates AI subtitles with a bilingual track. You can edit and export subtitle files. That helps when you're studying a lecture or watching content in a language you're still learning.
Cross-Device Continuity
Sign in once and your tabs, bookmarks, and files follow you. Start a video on your phone, pause, and pick it up on the desktop with your place and settings intact. The handoff is easy to miss until it's gone.
Pros and cons
Pros
- Combines search, cloud storage, and document tools in one app, cutting the number of apps you juggle.
- The Qwen assistant handles real reasoning tasks like calculations and multi-step questions, not just lookups.
- Generous cloud storage and unthrottled transfers make it a practical backup option for large files.
- Scanner and translation tools cover common office and study chores without extra software.
- Cross-device sync keeps work moving between phone, tablet, and desktop.
Cons
- The interface and much of the content assume Chinese, which raises the barrier for non-Chinese readers.
- You need an account to sync anything, so there's no fully private, login-free option.
- Free storage is small, and the paid tiers are priced in yuan, which adds friction for users outside China.
- Some features lean on services that perform best within China, so results can vary elsewhere.
