LINE ActEngine AI Explained: LINE Plus's AI Agents

#What Is ActEngine AI?

ActEngine AI is an AI agent platform for enterprise customer service and sales, launched by LINE Plus Corporation on March 12, 2026 (LINE Plus press release). LINE Plus presents it as its full entry into the B2B AI market. Its agents are "action-oriented": instead of only answering questions, they carry out steps in a company's business processes. Companies build and run the agents in an operations portal, and LINE Plus also offers services that turn a company's customer service and sales data into formats large language models can use.

Key facts as of October 2026:

ActEngine AI is a B2B platform, not a LINE Official Account feature: the announcement doesn't mention LINE Official Account, and we found no self-serve sign-up.

#The Two Agents: Customer Service and Sales

#Customer service agent

According to LINE Plus, the customer service agent goes beyond Q&A chatbots. It covers the support workflow from the first response through complaints to resolution, acts on business processes and improves from the results.

A LINE MAN Wongnai press release published by Thairath on April 29, 2026 gives concrete examples from its merchant support: the AI connects to back-end systems to update menus and opening hours, fix payment problems and adjust ad settings in real time, and it was built on more than 100 standard operating procedures and real conversation data (Thairath).

#Sales agent

The sales agent's main feature is "Outbound Action". It analyzes real-time data such as order patterns, visit frequency and discount sensitivity to choose the audience, the timing and the approach, then creates and sends personalized promotions. LINE Plus says it is designed to connect to ad execution and promotion settings, and describes it as "1:1 Sales AI" for small and medium merchants that traditional sales teams found hard to cover.

#First Deployment: LINE MAN Wongnai

LINE MAN Wongnai is a Thai food delivery and restaurant platform with more than 700,000 merchant partners. According to LINE Plus, about 80% of its restaurant merchants are run by one or two people.

How to read these numbers:

• They are company-reported, not independent measurements.
• They describe merchant support: the "customers" are restaurants using LINE MAN Wongnai's merchant portal, not consumers ordering food.
• The Thai press release published by Thairath puts the handling-time reduction at more than 66%, while LINE Plus's announcement says more than 60%.
• Neither source says whether merchants talk to the agent through LINE chat or through the merchant app.

#What LINE Plus Says Comes Next

• Grow ActEngine AI into a global B2B AI platform, serving Asia and global markets.
• Expand into "various industries including finance and retail", in the words of Hyunjun "Jayce" Shin, Head of B2B AI Business at LINE Plus.
• Voice-based AI agents for real customer consultation and sales are in preparation.

These are plans. The announcement gives no dates and names no other customers.

#What We Don't Know Yet

In October 2026 we couldn't find:

• a price or a pricing model;
• a product page or public sign-up beyond the press release;
• which countries and languages are supported outside the Thai deployment;
• whether ActEngine agents can be connected to an ordinary LINE Official Account.

If you're a large company interested in ActEngine AI, ask LINE Plus or your LINE representative directly, and treat third-party articles that quote figures beyond the press release with caution.

#What It Means for Smaller Businesses

ActEngine AI is built for large platforms with back-end systems and hundreds of thousands of cases a year. A shop or clinic can't buy it today.

The closest thing LINE offers smaller accounts is in Japan: since November 2025, the AI chatbot (beta) in LINE Official Account picks answers from Q&As the owner registered, with the Chat Pro option at ¥3,000 a month excluding tax (LY Corporation). LY Corporation has also announced a "LINE OA AI mode" that serves customers 24 hours a day, with pricing not yet decided as of October 2026 (Agent i for Business).

Our opinion: the useful lesson from the LINE MAN Wongnai case is preparation, not the model. Before any AI can act for you, you need written answers, clear procedures and a defined way to reach a person. That work pays off whatever tool you use:

1. List the 10 to 20 questions customers ask most and write the answer you'd approve for each.
2. Decide which requests always need a person (refunds, complaints, medical or legal questions) and how customers reach one.
3. Put the most-used answers behind rich menu buttons, so customers find them without typing.
4. Keep customer notes where they already live, such as chat tags in LINE OA Manager or your own system.

Our LINE auto-reply message examples and customer service automation guide help with steps 1 to 3.

#What You Can Use Today

LineBot.pro is independent and isn't part of ActEngine AI. For small teams, it covers the "approved answers" approach:

• Keyword bot: 1 to 8 intents with 1 to 15 keywords each, every intent answered with a Rich Message card you approved. Optional AI routing reads unmatched messages and only picks one of your intents (1 credit per message checked, with a daily cap); the AI never writes answers. Handoff keywords pause the bot for that customer. 1:1 chats only. See LINE chatbot.
• AI generators: reply cards as Rich Messages for 8 credits each and rich menus for 10 credits, which you upload in LINE OA Manager.
• Campaigns: an AI-made Flex message broadcast to all friends or a list of user IDs, now or scheduled.

What it doesn't do: agents that act inside your systems, personalized outbound sales, voice, or analytics. If you need LINE connected to your booking or order system, that's custom LINE development.

New accounts get 50 free credits with no card needed; after that, one-time credit packs, no subscription, and credits don't expire.
