Z.ai is a free AI assistant that brings presentations, writing, and coding into one conversational interface. Leveraging large language models, it lets you generate polished slide decks with AI slides, craft professional‑grade text for emails, reports, or blogs, and write or debug complex code. Beyond content creation, Z.ai supports deep research and information search, helping you gather facts, summarize long documents, and overcome writer’s block, while its code agent can explain snippets, refactor functions, or build scripts from scratch. An intuitive chat interface means no steep learning curves: simply tell Z.ai what you need, a strategic deck, marketing copy, or a data‑analysis script, and get instant, contextually relevant results. With support for multiple languages (including Chinese), native function calling, and up to 128K token context length, Z.ai handles everything from brainstorming ideas to automating repetitive writing or coding.
