LINE is where a lot of planning happens in Thailand, Japan and Taiwan, often in groups: family trips, condo committees, teams and suppliers. Most AI on LINE is either a one-to-one chat account or a bot that answers a business's customers. Few work inside the groups where people actually decide things. Here is what each option does, checked on its own pages on 12 October 2026.
Cole is an AI assistant you add as a LINE friend (@pocodot or lin.ee/WY8gSoF). New users sign in with LINE from the chat and get 150 one-time credits to start. You can then invite Cole into any LINE group. It replies when someone writes its name, @mentions it or replies to it, and keeps the rest of the group's messages as background so it can answer "what did we agree?".
In a group, Cole can post reminders for everyone at a set time, @mention a member to nudge them, and treat a batch of photos as one request. In your private chat it works with your own Gmail, Google Calendar or Outlook and asks before anything goes out in your name. On paid plans it can make phone calls for you, including in Thai.
- Works in LINE groups: once one member agrees to pay for the group, everyone can ask
- Reminders posted into the group, once or every week
- Replies in the language you write in, Thai included
- Uses each person's own connected email and calendar; the payer's accounts are not used for people outside the payer's account without a yes
- The same assistant in WhatsApp, iMessage, Telegram and Slack
- Free to start with 150 one-time credits; paid plans from $19 a month for 2,000 credits
Agent i is LY Corporation's AI agent, used from the LINE app and Yahoo! JAPAN. Its pages are in Japanese. In July 2026 LY announced "Agent i in chat", which will let you call Agent i inside LINE one-to-one and group chats, with release planned within 2026 (LY release, 2 July 2026).
Since 5 October 2026 a scheduling agent, switched on through LINE Labs, helps friends pick a date inside a LINE chat and can add the result to LINE Calendar. LY says it is offered in Japan (LY release). LY sells a LINE AI services unlimited plan at ¥750 a month including tax; its page does not list which features that covers (LYP Premium). LY ended its earlier LINE AI Assistant service on 7 January 2026 (notice).
- Group chat feature announced, not yet released when we checked
- Japanese service; the scheduling agent is offered in Japan
- Calendar help is LINE Calendar through the scheduling agent; no email actions stated
AI Chat-kun (AIチャットくん) is a LINE account by Picon that you add as a friend to chat with AI, in Japanese. Its FAQ says it is free with a daily limit and that a Premium plan removes the limit (FAQ). The Premium price is shown inside the chat.
LY Corporation's own case study from 2023 says it was made usable in LINE groups (LY case study). Picon's current pages do not mention groups.
- A chat partner for questions, not an assistant that acts on your accounts
- Japanese
- Group use only mentioned in a 2023 case study
This is a feature for businesses with a LINE Official Account. Generative AI reads what a customer writes and replies automatically (LY notice, 13 November 2025). LY's Japanese notice states that it does not reply in group chats.
It comes with a paid chat add-on: ¥3,000 a month before tax in Japan (price), 555 THB a month before VAT in Thailand (price), and NT$100 in Taiwan (LY Taiwan).
- Answers a business's customers; it is not a personal assistant

What to check before you choose
- Groups or one-to-one? Most LINE AI accounts only work in a private chat. If your plans happen in groups, check that the assistant replies there.
- Personal or business? An Official Account chatbot answers a company's customers. A personal assistant works for you and your group.
- Whose accounts does it use? In a group, an assistant should use each person's own email and calendar, never the group owner's for someone else.
- Language. Check that it answers in the language your group writes in.
