Z.ai

Z.ai started as a free AI Swiss Army knife — presentations, writing, coding — all without a subscription. For students or casual users, that zero price tag is unbeatable. The conversational interface works well for quick drafts or slide decks, and unlimited usage means you never hit a paywall mid-task. But the real news is ZCode. Launched July 2026, this agentic development environment powered by GLM-5.2 puts Z.ai in direct competition with Cursor and GitHub Copilot — and it's free. If you're a developer who wants an autonomous coding assistant without paying $20/mo, ZCode is worth a serious look. Early HN buzz (495 points) suggests it has genuine capability. Where Z.ai falls short is transparency. The underlying models (GLM-5.2 in ZCode, likely the same in the assistant) are open-weight on Hugging Face, but the company doesn't disclose details about data handling, security, or model limitations for the web interface. This will give pause to privacy-conscious teams or enterprises needing compliance. For everyday productivity, Z.ai is a solid supplement to your main tool — great for generating a first draft or a presentation outline. But for critical work that requires reliability, integration depth, or advanced formatting, we'd still lean on Claude or ChatGPT. If coding is your primary need, ZCode is surprisingly compelling — try it as a free alternative before paying for Copilot.
