A ChatGPT bot for Line, because not everyone lives on Discord

What it does This is glue code between the Line Messaging API and OpenAI. Drop it into a Line channel and it becomes a ChatGPT terminal: text hits gpt-3.5-turbo, voice notes are transcribed by Whisper and answered in text, and a slash command triggers DALL·E 2 image generation. It can also summarize YouTube videos and a specific list of Taiwanese news articles. Users supply their own OpenAI token and can set custom system prompts per chat.

The interesting bit The bot ignores the usual Discord-or-Slack crowd and targets Taiwan’s dominant messenger. It even scrapes and summarizes local outlets like 聯合報 and ETtoday, which makes it feel less like a generic Western wrapper and more like a regional utility.

Key highlights

• Chat, voice-to-text, and image generation inside a single Line thread
• Per-user OpenAI API key registration and custom system prompts
• On-demand conversation wipe via /清除
• Summarizes YouTube videos and a named roster of Taiwanese news sources
• Tuned for Replit’s free tier, which means it expects an external cron job to stay awake

Caveats

• Requires an external cron job to survive Replit’s free-tier sleep
• Documentation is entirely in Traditional Chinese, so English readers will need translation help

Verdict Grab this if you need a quick, Mandarin-friendly ChatGPT presence inside Line. Skip it if you are looking for deep framework abstractions or self-hosted infrastructure.
