See what GLM says about your brand.
GLM is the model Z.ai, formerly Zhipu AI, sells to developers and companies, about 7 million of them by August 2026. Visibian asks GLM your buyers' questions, daily or weekly, and shows whether it names you.
The model developers build into their own products.
Where it runs decides which engine it searches.
A buyer in Shanghai and a buyer in London can ask GLM the same question and get pages from different search engines.
GLM searches the web with a tool built into its API. On Z.ai, the international service, the tool uses one search engine, Jina. On Zhipu's platform in mainland China, it can use Sogou, Quark or Zhipu's own search.
GLM also answers inside other companies' apps and tools, built on Z.ai's API. The search engine behind those answers follows the platform the builder chose.

4 things to check for GLM.
Be findable in Sogou and Quark
If you sell in mainland China, check that your key pages appear in both. They are 2 of the engines GLM's search uses there.
Put the answer in the text
A search tool passes on what the page says in words. An answer hidden in an image, a PDF or a script may never reach GLM.
Expect to be described in other products
Developers call GLM from their own apps. One accurate, current description of your brand is what those answers can draw on.
Count the visits
Ground Truth counts the people chat.z.ai and chatglm.cn send to your site, beside the answers that sent them.

Why it picked someone else
Why not me? says whether your page was never retrieved, read and passed over, or retrieved but not cited.
Visibian asks GLM through Z.ai's API with its built-in web search on, using the search engine Z.ai supports, so every answer that searched comes with the pages it drew on. The same questions go to the 11 other assistants on every plan. Checked 5 November 2026.
Asked before you ask.
How do I check what GLM says about my brand?
Add your brand and the questions your buyers ask. Visibian asks GLM each one on your schedule and keeps the answer in full, with the pages its search returned.
Does GLM search the same way in China?
No. On Z.ai, GLM's search uses Jina. On Zhipu's mainland platform it can use Sogou, Quark or Zhipu's own search, so the pages it finds can differ.
Who makes GLM?
Z.ai, the company formerly known outside China as Zhipu AI. It sells GLM to developers and companies through its API, and runs chat.z.ai.
Does Visibian use the GLM app or the API?
Z.ai's own API, with the built-in web search on. It is the official route, and it returns the pages each searched answer drew on.
