What it does

Built for my mom who couldn't use ChatGPT. Three free AI tools: Prompt Wizard (guides you to better prompts), Myth/Truth Wizard (fact-checks viral claims), and AI Detector (spots AI-generated content). Free signup. Available in 5 languages.

Zhirong (Mark) Huang writes about AI systems, agent reliability, governed memory, and the engineering tradeoffs behind production software.

I build AI systems, memory tools, and production software, then write down the decisions, mistakes, and tradeoffs that changed how I think. RAG is not magic memory. A practical explanation of chunks, embeddings, vector search, graph-backed memory, and why durable AI memory needs provenance, conflict handling, and retrieval policy. A personal journey from Claude Code skills to TypeScript state machines, MCP tools, and finally SDK-based AI workflows. Skills help, tools help, but prompts are not enforcement and LLMs should not own the control plane. AI adoption is not just tool selection. Even companies that think they do not need AI need to understand where AI fits, what should stay…from markhuang.ai

  • 22 GB of Hacker News in SQLite▲730

    Community, All the HN belong to you. This is an archive of hacker news that fits in your browser.

Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
