A class action lawsuit will be filed against an artificial intelligence(AI) chatbot service called "Lee Luda."

Developed by a local startup, the chatbot has been mired in controversy over its use of discriminatory and offensive language as well as an alleged leak of personal information.

A notice recruiting victims of the privacy leak has been posted on an online platform for joint litigation.

A representative of the lawsuit said in the message that Scatter Lab, the chatbot's developer, collected personal information of its users without proper consent and used it as learning algorithms in training the AI.

The representative further said that people's real names, addresses and bank account numbers have been exposed, which is punishable under the Personal Information Protection Act, and added that victims have the right to claim compensation for psychological damage.

The Facebook-based deep learning chatbot was suspended early this week following complaints. It had gained popularity, attracting more than 750-thousand users since its debut late last month.
