ERNIE Bot

ERNIE Bot (Wenxin Yiyan) is Baidu’s assistant built on its in-house ERNIE models, and one of the first Chinese AI products opened to the general public. Its main advantage is not that the model stands out on its own, but that it sits on top of Baidu’s search engine, encyclopedia and document library — a natural edge when you are looking up Chinese-language information or writing Chinese material.

Day-to-day it is well rounded: Q&A, writing, summaries, translation and image generation are all covered, the Chinese is tidy and formal, and answers on policy or general-knowledge questions tend to be careful. Integration with other Baidu products is a practical selling point too — calling it from inside Baidu Netdisk or Wenku to work on a file saves effort for people already living in that ecosystem.

To be fair about it, ERNIE Bot is not the reputation leader in China’s crowded assistant market. For hard reasoning, coding and long documents, many users lean towards DeepSeek, Kimi or Qwen instead. It works best as a safe, general-purpose Chinese assistant rather than the first choice for difficult problems.

Key features

• Chat and Q&A: Everyday questions, explanations and suggestions, with clearly structured, formal Chinese answers.
• Web search: Uses Baidu Search to pull in recent information, which helps with China-specific news and topics.
• Writing help: Drafts copy, summaries, reports and emails, and rewrites or polishes on request.
• File reading: Upload a document to get a summary, ask questions about it or pull out key points.
• Image generation: Creates images from text descriptions — fine for simple illustrations and rough concepts.
• Agents: A large catalogue of ready-made assistants from Baidu and third parties that you can use directly.

How to use

1. Go to yiyan.baidu.com, or install Baidu’s official mobile app for it.
2. Log in with a Baidu account; a phone number is enough to register one.
3. Type your question, or use the upload button to add a document.
4. For images, describe the subject, style and aspect ratio in the prompt.
5. For facts that matter, check the cited sources before relying on the answer.

Best for

• Everyday Chinese writing: notices, summaries and promotional copy where formal correctness matters.
• Looking up domestic information: Baidu Search gives good coverage of local news and lifestyle topics.
• People already using Baidu products: call it from Netdisk or Wenku without moving files around.
• A first AI tool: simple interface and direct access in mainland China.

Strengths and limitations

Strengths

• Directly reachable in mainland China with a Baidu account, and core features are free.
• Backed by Baidu Search and a large body of Chinese content, so domestic coverage is broad.
• Covers chat, writing, images and file handling in one place.

Limitations

• Reasoning and coding show no clear edge over China’s leading models.
• Answers can be cautious and padded with boilerplate; you often need follow-ups to get specifics.
• Product entry points and naming change fairly often, and the app and web versions don’t always match feature for feature.
