LINE AI assistant
Your LINE AI assistant, inside ChatGPT and Claude
Link LINE once, then ask ChatGPT, Claude or any AI app that supports MCP to catch you up, find old messages and draft replies. Nothing is sent until you approve it.
Free to start. No install. Every send needs your OK.
What your AI can do with LINE
ConnectChats gives your AI app a small set of tools. These are the ones it uses with LINE, and only for the chats you share.
-
See your chats
Your AI lists the LINE chats you shared, unread first, so it knows where to look before it answers.
list_chats -
Read a conversation
Ask about one chat and your AI reads what you have not seen yet, or goes further back when you need the history.

Catch you up
Get the short version of a busy chat: what was decided, which questions are open and what needs your answer.
get_messages_to_summarize -
Find any message
Search your LINE history by word, name or topic. Your AI quotes the message and tells you which chat it came from.

Draft replies
Your AI writes a reply in the chat's language and your tone. It is saved as a draft you can read and edit.

Send with your OK
Approve a draft and ConnectChats sends it from your own LINE account. Auto-send only runs in chats where you turn it on.

LINE in ConnectChats
ConnectChats signs in to your LINE account the way LINE for PC does, and your AI app sees the chats and groups you share. Your phone stays your main device.
- One to one chats and groups are supported. LINE official accounts you follow appear as chats too.
- Stickers show up as short text descriptions, along with photos, videos and voice messages.
- Each linked chat starts with its last 200 messages, then every new message arrives as it is sent.
- LINE allows one PC sign-in at a time, so linking ConnectChats may sign out LINE on your computer.
