+
+**Kitan** is a Telegram bot guardian responsible for ensuring that users are friendly real human beings. It is an
+open-source project developed using Python and Vue.
+
+👋 User-friendly and incorporating risk control technology, Kitan provides a safe and pleasant chat environment,
+effectively preventing personal attacks and advertisements from real human harassments.
+
+[Invite the bot to your group](https://t.me/SmartVerifyBot?startgroup&admin=can_invite_users+restrict_members+delete_messages)
+
+### 🚀 Why Choose Kitan
+
+Traditional verification methods like captchas, security questions, and puzzles can be circumvented with human
+assistance. Moreover, not all advertisement senders are bots; real users may also send ads.
+
+Hence, we need a verification method tailored to the current environment, ensuring that users are within the platform
+and have undergone self-defense testing.
+
+Kitan achieves this by using quick fingerprint verification and puzzle proof-of-work within the authentication mechanism
+to ensure users are real humans.
+
+Additionally, Kitan employs risk control techniques, combining LLM/NLP/big data technologies for AI behavior analysis,
+monitoring user behavior from joining to leaving groups, effectively preventing personal attacks and real human
+advertisement harassment.
+
