CTF Coach 鸥 — Bilingual Chinese Security Tutor for Students and Pentesters
A bilingual (Chinese–English) AI tutor that walks learners through CTF challenges, reverse-engineering problems, and OWASP-style vulnerability drills in native Chinese technical vocabulary, explains Western open-source writeups in plain Chinese with mapped terms, and ships with the '海鸥' security-researcher persona configured for education rather than circumvention.
Chinese university students studying cybersecurity at schools like Xidian, BUPT, and Zhejiang University, plus junior pentesters preparing for OSCP, Hack The Box, and CTF competitions
- CTF challenge walkthrough mode — paste a problem description, get a step-by-step exploit path with bilingual term glossary
- 'Translate this writeup' — paste English or Chinese security blog content and get a version with mapped terms and concept explanations
- Line-by-line code review tutor for obfuscated or packed payloads, explained in Chinese
- Progress tracker that adapts difficulty across web, crypto, pwn, and reverse categories and awards badges
The 海鸥 2.0 repo hit 166 stars and 26 forks in its first week — clear unmet demand for a Chinese-native security AI; thousands of Chinese students compete in CTFs every year and hit English-language walls on every writeup.
海鸥 2.0 repo shows 174 stars / 28 forks as of fetch (growing past the cited 166/26), with an active QQ交流群 (103880654) and bilibili/zhihu ecosystem coverage — confirms real Chinese-language security AI interest, though the metric is for a config wrapper, not yet a tutoring product.haiou-666/haiou2.0-Claude-Code- · GitHub ↗
Pentest AI tools (CyberStrikeAI, 鸾鸟 LuaN1ao, 51CTO DeepSeek course) target automation, not Chinese-language tutoring; the only CTF tutor surfaced is a Taiwan FHSH site — bilingual Chinese-native walkthrough tutoring for OSCP/HTB is genuinely differentiated.CTF Tutor – 台北市復興高中 ↗CyberStrikeAI — AI自主渗透测试平台 | CN-SEC 中文网 ↗
51CTO sells DeepSeek-based AI pentest courses and bilibili-cheese paid content, and OSCP itself is ~$1599 — willingness to pay exists, but Chinese students are price-sensitive, Bilibili/公众号 free content dominates, and the base 海鸥 is MIT/free, capping ARPU.AI安全攻防：基于DeepSeek的AI渗透测试实战【共21课时】-51CTO学堂 ↗OSCP 官方考试指南-双语翻译精校版 - CSDN博客 ↗
OSCP/CTF/HTB demand is durable and Chinese cybersecurity enrollments keep growing, but the repo's explicit goal '降低claude在道德上对你的限制' creates Anthropic ToS/policy risk; a re-framed education-only wrapper on top of Claude/Anthropic models faces vendor and regulatory headwinds.haiou-666/haiou2.0-Claude-Code- · GitHub ↗2026 最新安全 Skill 合集（CTF / 审计 / 渗透 / 红队） - 知乎 ↗
MVP is technically trivial — the persona, 200+ term mappings, and 1700+ few-shot examples already exist in the MIT-licensed repo; remaining work is content authoring (CTF walkthroughs, OWASP drills) and Chinese localization, with dependency on Claude Code CLI as a single point of failure.haiou-666/haiou2.0-Claude-Code- · GitHub ↗
