Three core use cases

A customer asks on LINE. Your AI takes it from there.

Bring your existing AI, data, and workflows into the conversation.

Answer questions. Find the details.

Connect product, order, or service information so your AI can answer customers without your team repeatedly looking things up and pasting replies.

Help with bookings and reminders.

Connect an existing booking or scheduling workflow to LINE so customers can check times and receive appointment, order, and status updates.

Introduce products. Keep talking.

Let your AI use the product and campaign information you provide to answer questions, introduce offers, and help customers take the next step.

Works with the data and tools you connect

Order and booking use cases require the relevant data or existing workflow to be connected first. Proactive messages follow your LINE plan, friend, and consent rules. The conversations above are illustrative.

THREE STEPS TO START

Start with the job, not the setup.

Describe what you need, follow the account confirmations, and try your first conversation.

  1. Describe the work

    Tell your AI which tools you use and what it should help you do on LINE.

  2. Connect the account

    Use your existing account or get guidance creating one. You confirm login and authorization yourself.

  3. Try a conversation

    Connect the data or workflow you need, check an answer, and start using it.

FAQ

Before you get started.

Who is this for?
Operators and consultants who already use AI, have a specific workflow in mind, and want their own AI to work with customers through LINE. Examples include order questions, service answers, and appointment reminders.
How is this different from an AI customer-service product?
The focus here is connecting your own AI, data, and workflows to LINE. If you need a ready-made support workspace, service management, and team collaboration, Crescendo Lab's CAAC is another option to evaluate.
Do I need to write code?
You do not need to understand integration terminology before starting. Your AI guides the connection and testing. You still handle account login, authorization, and important confirmations; complex data or business-system connections may need help from your team.
Can I use my existing LINE Official Account?
Yes. Keep your existing account and friends. You need account management access and must complete the required settings. The account, friends, and LINE plan remain under your control.
What if I do not have a LINE Official Account?
Tell your AI what you want the account to do. It guides you to LINE's official pages to create one. You handle login and important confirmations, then continue the connection and testing.
Can my AI look up orders or help with bookings right away?
You first need to connect your order or booking information, or the relevant tools. What your AI can do depends on the data, workflows, and permissions you provide. Connecting LINE alone does not grant access to that information.
Who controls my account and data?
You manage the account and confirm login and authorization yourself. Enter sensitive information through the secure page, not in chat. You also decide which data and tools your AI may use.
Does sending LINE messages cost extra?
Proactive message quotas and charges depend on your LINE Official Account plan. AI and connected-service costs depend on the plans and tools you use. Confirm expected usage and the right setup before you start.
