Add RegAI on LINE

Sign-in requiredLast updated: 2026-11-06

Once you add RegAI's LINE Official Account, you can look up laws and decisions and ask legal questions right in a LINE chat, by text or voice message. For an introduction with screen examples, see the Regbot page.

Add it as a friend

The LINE Official Account link in the site footer opens the add-friend screen too.

Sign in to RegAI with LINE

You need to sign in to RegAI with LINE first.

  1. After adding the account, the chat shows a welcome message asking you to sign in with LINE.
  2. Tap 「用 LINE 登入 RegAI」 (Sign in to RegAI with LINE) and finish signing in.
  • If you don't have a RegAI account yet, signing in creates a free one.
  • If you already signed up with email or Google, sign in that way first and choose Connect LINE in Account settings; see Signing in and your account. Your LINE lookups and questions then use that account.
  • If one LINE account is connected to several RegAI accounts, LINE uses the account you chose most recently when signing in with LINE.

The menu

The menu at the bottom of the chat (in Chinese):

The RegAI LINE menu

  • 「查法條」 (laws): look up articles by number or keyword.
  • 「查裁判」 (decisions): look up a decision by case number, a court's latest decisions, or court information.
  • 「問 RegAI」 (ask RegAI): type a legal question.
  • 「我的帳號」 (my account): see your plan and usage.
  • 「使用說明」 (guide): show the guide.

How to type each command: see LINE commands.

Allowance and history

  • Lookups and questions in LINE use your RegAI account's allowance; see Pricing.
  • Your legal questions and RegAI's answers are saved in the account's chat history, so you can continue them on the website. Law lookups are counted, but their content isn't kept.

Note: answers in LINE are shorter. For the full answer, tap the 「RegAI.tw」 link under it to open it on the website.
