What is Chat.z.ai?

Chat.z.ai is a next-generation AI chatbot platform developed by Zhipu AI, the company behind the broader Z.ai ecosystem. Designed to enable natural, fluid, and emotionally intelligent conversations, Chat.z.ai serves as a multilingual AI companion that supports both English and Chinese users.

At its core, Chat.z.ai is powered by the GLM (Generative Language Model) — Zhipu AI’s proprietary large language model, built to rival models like GPT and LLaMA. This foundation allows Chat.z.ai to handle complex conversations, understand context, and generate responses that feel more realistic and personalized than traditional AI bots.

The platform allows users to interact with various AI personas or create their own custom characters. Whether you’re looking for emotional support, casual conversation, or engaging roleplay, Chat.z.ai adapts to your preferences using advanced natural language understanding.

In essence, Chat.z.ai is not just a chatbot — it’s a window into Zhipu AI’s vision of emotionally-aware, real-time AI communication.

When Was Chat.z.ai Launched?

Zhipu AI, the company behind Chat.z.ai and the broader Z.ai ecosystem, was established in 2019 in China. Since its inception, the company has focused on building large-scale language models and pushing the boundaries of generative AI.

The foundation of Chat.z.ai lies in Zhipu AI’s proprietary GLM (Generative Language Model) series, which has evolved significantly over time:

• GLM-130B: One of their earlier large-scale models, known for strong performance across multiple languages.
• GLM-4: A major leap forward, offering better reasoning, longer context handling, and more natural dialogue flow.
• GLM-4.5: The most recent version (as of mid-2025), which powers many of Zhipu AI’s real-time chat products, including Chat.z.ai.

While Zhipu AI had been developing AI models and tools for several years, the public launch of Chat.z.ai as an interactive chatbot platform happened in 2025. With this release, Zhipu AI aimed to make its advanced AI capabilities accessible to everyday users around the world, not just developers or enterprise customers.

Key Features of Chat.z.ai

Chat.z.ai offers a diverse set of features that make it stand out in the AI chatbot ecosystem. Whether you’re using it for conversation, productivity, or creative tasks, the platform brings advanced capabilities powered by Zhipu AI’s GLM models.

Here are some of its key features:

1. AI Chat Assistant (Like ChatGPT)

At its core, Chat.z.ai functions as a powerful AI assistant — much like ChatGPT. It can answer questions, hold natural conversations, help with writing, translate languages, and even simulate emotional or fictional dialogues through custom AI personas.

2. AI Slides (Automated PPT Generation)

One standout feature is AI Slides, where users can input a topic and generate structured presentation slides (PowerPoint-style) automatically. This makes it highly useful for students, professionals, and content creators.

3. Multimodal Support

The platform supports multimodal interactions — meaning it can process not only text but also images and possibly audio inputs (depending on future updates). This aligns with the broader trend in AI toward combining visual and textual understanding.

4. Free and Login-Based Access

Chat.z.ai offers both free access and enhanced functionality through login-based accounts. Guests can try many features, while registered users get longer sessions, better continuity, and additional tools like AI Slides and long-form memory.

5. Bilingual Interface: English & Chinese

The interface is available in both English and Chinese, making it accessible to a wide global audience, especially in East Asia where Zhipu AI is based.

6. Long-Context Reasoning

Thanks to the power of GLM-4.5, Chat.z.ai can handle long-context conversations, retaining memory across messages and offering more coherent responses — ideal for storytelling, brainstorming, and in-depth discussions.

GLM-4.5 Model: Z.ai’s Supercharged Brain

At the heart of Chat.z.ai lies GLM-4.5, the latest and most advanced version of Zhipu AI’s proprietary large language model series. This model is the foundation for everything from real-time chat to document creation and AI-powered reasoning on the platform.

1. Performance Benchmarks

GLM-4.5 has shown competitive results in several standard AI benchmarks, often matching or even outperforming popular models like Claude, Grok, and GPT-3.5 in specific areas. According to internal evaluations, GLM-4.5 excels in long-form understanding, multilingual capabilities, and reasoning depth.

2. GLM-4.5 vs Claude/Grok

While Claude by Anthropic focuses heavily on safe and ethical reasoning, and Grok (by xAI) emphasizes real-time and internet-connected answers, GLM-4.5 strikes a balance between accuracy, depth, and freedom of expression — especially in Chinese and English contexts. In tasks requiring contextual memory, logical reasoning, and creative writing, GLM-4.5 holds its own against these models.

3. Coding, Math & Logic Proficiency

GLM-4.5 is equipped with enhanced capabilities in:

• Programming (Python, JavaScript, etc.)
• Math problem solving
• Step-by-step logical reasoning

This makes it suitable not just for casual chats, but also for students, developers, and researchers looking for reliable AI assistance.

4. Token Pricing & API Access

Zhipu AI provides API access to the GLM-4.5 model through its developer portal, allowing integration into third-party apps and tools. Token pricing is generally more affordable than some Western LLM providers, especially for Chinese developers. This competitive pricing structure makes GLM-4.5 a practical choice for startups and enterprises building AI products in the region.

AI Slides: Chat.z.ai’s Killer Tool

One of the standout features of Chat.z.ai is AI Slides — a powerful tool that sets it apart from typical chatbots. Designed for speed and simplicity, AI Slides allows users to instantly generate presentation slides by simply entering a text prompt.

What Is AI Slides?

AI Slides is an automated presentation generation feature within Chat.z.ai. Instead of manually creating a PowerPoint or Google Slides deck, users can just describe a topic in a few words or sentences, and the AI generates a full slide deck with structured content.

How Does It Work?

The process is remarkably simple:

Prompt → Slide Draft → Exportable PPT

1. User enters a topic, like “History of AI” or “Marketing Strategies for 2025.”
2. Chat.z.ai processes the prompt and breaks it into a multi-slide structure with titles, bullet points, and summaries.
3. The slides can be previewed and exported, often in PPTX or similar formats, depending on the platform’s export capabilities.

Real-World Use Cases

AI Slides is especially useful for:

• Students: Instantly generate classroom presentations or project outlines.
• Professionals: Create client pitches, product overviews, or meeting decks in seconds.
• Teachers: Build educational content quickly, with minimal manual effort.

Limitations

While AI Slides is highly convenient, it does have some limitations:

• Design is basic: The focus is on content, not visual flair. Users may need to edit the slides afterward for branding or style.
• Language support: Works best in English and Chinese — performance in other languages may be inconsistent.
• No media embedding: Slides are usually text-based; images or charts need to be added manually.

How to Use Chat.z.ai

Whether you’re a first-time user or just curious about how Chat.z.ai works, this step-by-step walkthrough will help you get started quickly and make the most of its powerful features — especially chat interactions and AI Slides.

Step 1: Visit the Official Website

Go to the official site: chat.z.ai

You can use the platform as a guest (no login required), but for full access to features like long memory, AI Slides, and customization, it’s recommended to create a free account.

Step 2: Choose Your AI Model

After landing on the homepage, you’ll often see options for:

• General Chat Assistant
• AI Slides Generator
• Or custom AI characters created by the community

Select the mode depending on your goal — for normal conversation, go with the chat assistant; for presentation tasks, choose AI Slides.

Step 3: Enter a Prompt

Here are a few sample prompts you can try:

• For chatting:
  “Help me prepare for a job interview in tech.”
  “Explain the history of World War II in simple terms.”
• For AI Slides:
  “Create a presentation on digital marketing trends in 2025.”
  “Make slides about the water cycle for 8th-grade students.”

Chat.z.ai will respond with either a detailed message or a structured presentation, depending on the mode selected.

Step 4: Exporting AI Slides (PPT)

If you’re using the AI Slides tool:

1. Enter your topic prompt.
2. The AI will generate multiple slides with headings and content.
3. Look for the “Download” or “Export to PPT” button.
4. Save the file to your device and edit it further in PowerPoint, Keynote, or Google Slides as needed.

Is Chat.z.ai Safe to Use? (Privacy & Data Practices)

When using any AI chatbot, data privacy is a major concern. Chat.z.ai addresses this through several key policies and design decisions that focus on user control and security.

1. Compliant with Chinese Data Laws

Chat.z.ai is developed by Zhipu AI, a China-based company, and operates under Chinese cybersecurity and data protection regulations. These laws enforce strict handling of user data within Chinese borders, especially when it comes to AI models and cloud storage.

While this ensures strong regulatory oversight, international users may want to review how Chinese data laws align with their own privacy expectations.

2. No Signup Required for Basic Use

A major advantage of Chat.z.ai is that it allows anonymous access. Users can interact with the chatbot or generate slides without creating an account. This reduces the amount of personal information collected and provides a safer experience for casual or first-time users.

3. Enterprise Data Isolation

For corporate and institutional users, Zhipu AI offers enterprise-grade data isolation. This ensures that any information submitted during usage (such as documents, queries, or code) is kept separate from public models and not used to train future versions of GLM.

This makes Chat.z.ai suitable not just for individuals, but also for businesses concerned about data confidentiality and compliance.
