You can build a usable AI application with your own hands even if you cannot write code. Using a customer-support knowledge-base Q&A as the scenario and no-code platforms like Dify, Coze, and n8n, this article walks you through six steps — prepare the data, build the knowledge base, set the prompt, test, launch, monitor — each concrete enough to follow, without depending on interface details that go stale.

The common problem in resume screening is not slowness but that the criteria live in the interviewer's head — inconsistent and hard to articulate. This article turns the hiring criteria into a document that can actually be judged, then uses Claude, NotebookLM, and Dify to extract fields, match against the criteria with the original text as evidence, and generate interview questions, while holding the line on human decision-making and compliance boundaries.

They are all called AI, yet their capabilities and cost structures differ enormously. This article breaks the tools on the market into three levels — chat, collaboration, and agent — and gives you a decision table to first clarify which level a need belongs to, then talk tool selection and budget, so you avoid spending money on the wrong tool.

Facing a dizzying list of AI tools, trialing them one by one is the most expensive way to choose. This article gives you five screening questions — data sensitivity, error tolerance, integration needs, usage scale, and cost of failure — each mapped to which category of tool to pick, and ends with a decision-flow table that walks you through the whole judgment.

Can't find company policies or process docs, and keep asking colleagues instead? This article shows how to build an intelligent Q&A system with AI + RAG, so employees ask questions right in their instant-messaging tool and get accurate answers with the source document attached. The focus is on designing for retrieval accuracy and a miss-tracking mechanism.
