What it is
Overview
Z.ai is a multi-modal AI agent that handles design, coding, and conversations in a single interface. Built on GLM-5.2, it targets developers who want one tool for multiple workflows rather than switching between specialized apps. The 10.4M monthly visits come mostly from software engineers and full-stack developers who use it for code generation, debugging, and creative tasks. Early reviewers praise its coding capabilities and context understanding for complex instructions.

“best vibe coding app I tested - better than Replit, Base44, Cursor, WindSurf, and Kimi”
“Just tried asking chat.z.ai "How much does z.ai cost - I want a monthly plan comparable to claude code pro". chat.z.ai seems to suggest it uses Claude - and has no idea about "chat.z.ai". My follow up question at chat.z.ai was "Isn't this z.ai? I'm asking about your paid services, access to GLM models" with the response: Ah, I see the confusion-but no, I'm Claude, made by Anthropic. I'm not zai and have no affiliation with Zhipu Al or their GLM models. You're looking for Zhipu Al (i#AI) and thei”
“Hello! Really sorry for bothering anyone woth this long text, just wanted to clarify a problem: I have been using glm 5.1 for creative writing (my prompt — it’s chapter) for like two months now, have established a stable workflow, was really amazed at the way it writes — poetic, unhurried tone, attention to all details and everything else. Always used simply chat.z.ai without any subscription or anything — I am not against buying one, just didn’t seem necessary. So the style was simply immaculat”
“I've been using GLM-5.2 extensively over the past few days, primarily for software engineering tasks through OpenCode and Hermes-Agent, and it has genuinely impressed me.The biggest compliment I can give is that, during many coding sessions, it gave me a similar feeling to using Claude Opus. Not because the models are identical, but because of how reliably it understands context, follows complex instructions, and completes multi-step engineering tasks.I also tested it through Ollama Cloud using an API key, and the experience was consistently solid across different environments.What I appreciate most is that the team decided to open-source such a capable model. The AI community benefits enormously when high-quality foundation models are openly available, and I wanted to leave a review simply to thank and recognize the work that went into this release.Looking forward to seeing how the project evolves.”

“worse experience after suscribibng max plan, and customer support is even worse and not regulated like in europe. scammers!”
“cheap + fast + accurate feels like real combo tbh🔥”
“Dont even waste your $3 , it's cheap but garbaage, $3 is too much, even if it is free , your time wasted cannot be brought back. Trust me .”
“https://z.ai/subscribe doesn’t give actual numbers but better then asking a model question about its self or another model for that matter. Equivalent? Maybe for me glm burned through my free tokens but try using https://zcode.z.ai/en you will have glm free daily tokens so that hopefully will help if it’s the right product for you”

“20 minutes for a landing page? That's not just slow, that's unusable. Quality means nothing when velocity is zero.”
“Hi.I'm trying the https://chat.z.ai/ for the first time. I ask a refactor plan (not touch the code, just the plan) and it get's stuck or that's what I think I'm using the web interface. Do I need to purchase a plan or upload credits into an API? Appreciate any help”
“The model is already very capable. My main suggestion would be to continue improving stability and reducing occasional errors during long-running agentic workflows. As the ecosystem matures, even more consistency across extended coding sessions would make it an exceptional developer model.”

“Spent some time watching this and the part that caught my attention was the app generation flow. It looks useful for scaffolding ideas quickly, but I would still want to inspect the architecture before trusting it on anything serious. Feels more like a productivity booster than a replacement for real development work, which is probably the right positioning.”
“I'm super intrigued by this! The efficiency that consolidating all these tools can bring is immense, especially for small teams. Now, I wonder if they also plan to integrate community features. That could really enhance collaboration among users.”
