Build a Smart WeChat Bot: Integrate DeepSeek, ChatGPT, Kimi, and More

Introduction

A WeChat Bot is an automation software based on the WeChat platform that can simulate human user behavior to perform a series of tasks, typically for personal or business purposes. WeChat bots can perform the following functions and operations:

Automatic message replies: When users send messages to the bot, it can automatically reply with preset text, images, videos, or other types of messages.
Keyword triggers: The bot can trigger specific replies or actions based on keywords in user messages.
Group management: In WeChat groups, the bot can help manage group members, such as welcoming new members, kicking out rule-breaking members, and posting group announcements.
Message forwarding: The bot can forward received messages to other chats or group chats.
Scheduled tasks: The bot can be set to send messages at scheduled times, such as daily news, weather forecasts, reminders, etc.
Intelligent conversation: By combining natural language processing technology, the bot can understand and respond to more complex conversations.
Zombie follower detection: The bot can help users detect and clean up inactive or fake WeChat friends.
Data analysis: The bot can collect and analyze chat data for market research or user behavior analysis.
Customer support: Provides automated customer service for businesses, answering common questions and improving efficiency.

WeChat bots are usually implemented through WeChat’s API, third-party development frameworks (such as WeChaty), or by simulating the behavior of the WeChat client. Due to the restrictions on automation scripts by WeChat’s official policies, using WeChat bots may violate WeChat’s service terms, so care should be taken to comply with relevant rules and regulations.
