What is knowledge-base?

AI Spark Knowledge Base (AI Spark 知识库) is an open-source collection of practical AI guides maintained by people who use AI tools in their day-to-day work. The repository is written in Chinese and organized around the idea that real practitioners -- not instructors -- should share what they have actually tested. The stated goal is to help anyone who wants to use AI move from confusion to a working first workflow, and then from there to using AI to save time and increase output. The content is split into seven sections: an introductory track for people new to AI, a section on tools and language models with buying guidance, a section on AI-assisted coding and building software agents, a section on content creation covering topic research to multi-platform publishing, a section on productivity and automation, and an author index for contributors. There is also a paid community layer -- a group membership priced around 399 yuan per year that adds live sessions, recorded courses, and direct Q&A with the instructors. The free knowledge base includes guides on prompts, context windows, workflows, how to use tools like Obsidian with AI, and breakdowns of high-performing social media content. Material comes from two sources: tutorials written by the team's instructors based on their own experience, and archived posts that previously went viral on platforms like X and WeChat. Six instructors are listed, each with a public following on Chinese social platforms. Their backgrounds range from enterprise AI consulting and cybersecurity to full-stack development, content creation, and solo product building. The repository is updated regularly, with newer lessons covering tools like Codex, Claude Code, and AI-driven video editing. The knowledge base is free and permanently open. The paid community is a separate product with its own pricing and is not required to access the repository content.
