Keyword Alert Bot

What this bot does

Keyword Alert Bot is the public demo of an open-source keyword monitor. Tell it which words to look for and in which channels or groups, and it forwards you an alert as soon as a matching message is posted. Replies are in English and Chinese.

Features

• 🔔 Keyword subscriptions — /subscribe with a list of keywords and a list of channels, e.g. /subscribe iphone,sale tianfutong.
• 🔀 Many keywords and channels — separate several keywords or channels with commas in one command.
• 🧩 Regular expressions — match complex patterns instead of plain words.
• 👥 Groups and private chats — watch public channels, groups and private chats by invite link or ID.
• 📋 Subscription list — /list shows every subscription with its ID.
• 🗑 Unsubscribe — /unsubscribe by keyword and channel, /unsubscribe_id by ID or /unsubscribe_all at once.
• 🐳 Self-hosting — the code is on GitHub with a Docker image; the public bot is heavily loaded and cannot always join new channels, so the author recommends running your own copy.

How to use

1. Open the bot and send /help.
2. Send /subscribe with your keywords and channel usernames or links.
3. Get an alert in the chat whenever a matching post appears.
