Bendan Bot is a Telegram chatbot that adds a collection of playful utilities, mini-games, and automation tricks to group conversations. Think of it as a friendly group-helper that can react to messages, run small snippets of code, clean up messy links, and even cross-post Telegram channel updates to Twitter or Mastodon. The bot listens for specific commands and message patterns inside a Telegram chat. If you reply to someone's message with a command like "/eat," the bot formats a fun response such as "Alice ate Bob!" It also responds to casual conversational prompts in Chinese. For instance, if you ask a yes-or-no style question like "is it...?", the bot replies with a semi-random answer. Beyond the games, it has practical uses: it can strip tracking parameters from shared URLs, pin messages (automatically unpinning old ones to keep only ten pinned at a time), and execute small code snippets in Go or JavaScript. This tool is built for Telegram group admins and communities, especially those seeking to add personality and lighthearted interaction to their chats. A community moderator could use it to pin important announcements while letting the bot manage the pin limit. A channel owner could configure it to automatically share channel posts to a linked Twitter account. It is particularly well-suited for Chinese-speaking chat groups, as its conversational replies and encouragement features are designed around Chinese phrasing. The project is written in Go and is designed to be easily deployed, either on a traditional server or on a hosting platform like Vercel. The developer has placed a strong emphasis on privacy. While the bot needs to remember which messages it pinned so it can unpin the oldest ones later, it deliberately avoids storing any actual message content, keeping only the message ID and group ID for that specific administrative task.
