Independent AI community for global discussion | PromptCube

An independent AI community, AI forum and AI discussion group. Welcome, AI enthusiasts — helping AI grow.

7,170 threads · 34 members · 1 replies

An AI community is where people compare models, tools and failures. PromptCube is an independent AI forum and AI discussion group: every thread has a stable URL, Chinese lives at the root and English under /en/, so a Cursor, Claude Code, Codex or Manus traceback is still searchable months later — and a global AI chat room is open for live discussion.

AI community vs AI forum vs AI discussion group
What is an AI community?
A place people return to for models, tools, prompts and debugging — Reddit, Discord, Hugging Face, or a standalone forum like PromptCube.
What is the global AI chat room?
A live room for Chinese and English speakers to talk about models, tools and shipping, alongside the forum threads.
