Beijing Yuanshi Technology · Chatbot · China AI
Wenxiaobai is a free all-purpose AI assistant app made by Beijing Yuanshi Technology that handles question answering, writing, web research, file analysis, and image understanding in one place, so you don't have to juggle five separate apps for a single afternoon of work. It combines a general chat model with reasoning options and can pull in live web results, so you get a single assistant for studying, office work, and content creation. The app runs on Android and the web. Its core features don't require a paid subscription.
About 问小白 - 全能AI
What Is Wenxiaobai
Wenxiaobai is an AI assistant app for everyday question answering and content work, not a coding tool or a research lab product. It's built around a general model from Yuanshi Technology and adds optional reasoning modes, web search, and academic search, so answers can include current information from the web instead of stale training data that cuts off months ago. Students, office workers, and creators use it to get from a fuzzy question to a usable answer or draft in one sitting. That's the whole pitch. One app, less tab-hopping.
The biggest draw is what you get for free. Core chat, search, and file reading cost nothing. Most rivals lock depth behind a subscription. The interface and most in-app guidance are in Chinese, so non-Chinese readers will need to work around the language. There's no official public API either. It's a consumer app first, not a building block for developers.
Getting Started
- Download the Wenxiaobai app from Google Play (package com.yuanshi.wenxiaobai) or open the web version at wenxiaobai.com.
- Create an account or start as a guest to reach the chat screen.
- Type your question or instruction in the text box, or attach a PDF, Word, PPT, or image for analysis. Files are optional.
- Switch on the reasoning or web search mode when you need deeper thinking or up-to-date sources.
- Copy the answer, export it, or keep chatting to refine the result.

Key features
Fast Question Answering
Wenxiaobai answers most questions within a second, which matters when you're searching for a fact and don't want to wait through a loading spinner while a slow model thinks about a simple request. Ask follow-up questions and it keeps the thread going, offering related questions when you aren't sure what to ask next. For simple lookups, it's often quicker than a search engine. No contest there.
Reasoning Mode with Parallel Thinking
The app offers reasoning models, including a DeepSeek-R1 option and its own parallel-thinking mode that runs several solution paths at once and then picks the strongest one before it answers you. That's the feature that makes hard math, logic, and coding questions more reliable. You get a cleaner answer without manually regenerating it five times. Big difference on tough problems.
AI Web and Academic Search
Beyond plain chat, Wenxiaobai searches the live web and academic sources, then returns structured results with links back to the pages it used, so you can trace a claim to its origin instead of trusting a black box. Think of it as a free AI chatbot that also cites its sources. The research mode can spin up longer reports with charts, which is handy for trend or market questions. If you need to check where a claim came from, the sources are there.
File and Image Analysis
You can upload PDFs, Word documents, PPT decks, and plain text and ask for a summary or specific details, which saves you from reading a fifty-page report just to find one number. The image tools read photos and screenshots, so you can ask about a chart, a product label, or a plant and get a plain-language answer. This is where a chat assistant starts to replace several separate tools. That's a real upgrade.
Long-Form Content Engine
A newer "5 Pro" line focuses on long documents, holding structure and facts across tens of thousands of words and keeping sources traceable, which matters once a project runs past a single afternoon of writing. It's aimed at people writing papers, reports, or long scripts rather than short replies. On projects that span days, less drift between drafts is a real benefit. Huge relief for long projects.
Writing and Creator Tools
Wenxiaobai drafts social posts, slogans, product names, and press-style copy, and it can imitate a writing style you provide. Creators treat it as an AI writing tool that turns a rough idea into a first draft fast. Big time saver. The output stays a starting point, not a finished piece.
Free Tier Across Core Features
Chat, search, and file reading stay free, and the previous "paywall shock" of similar apps isn't the default here. That makes it easy to test the assistant on real work before considering anything paid. It's the main reason budget-conscious users pick it over subscription-first rivals. Hard to argue with free.
Pros and cons
Pros
- Core chat, web search, and file analysis are free, so there's little risk in trying it.
- Reasoning modes handle complex math, logic, and code questions better than a plain chatbot.
- File and image upload cover documents, decks, and photos in one app.
- Responses are fast, often under a second for straightforward questions.
Cons
- The interface and most guidance are in Chinese, which slows down non-Chinese users.
- There's no official public API, so you can't build on top of it.
- Business tiers and exact higher-end pricing aren't clearly published, so budgeting is guesswork.
- Long reports can need a careful read, since sources occasionally don't line up with the text.
Frequently asked questions
Yes, the core chat, search, and document features are free. Some advanced long-content work sits behind higher tiers, and public pricing for those isn't clearly listed.
