Provide multilingual support on LINE with AI agents

Swiftask integrates your AI agents with LINE Messaging. Respond instantly to international customers in their native language without scaling your team.

Result:

Remove language barriers and boost global customer satisfaction on LINE.

Language barriers hinder your growth on LINE

Managing effective customer support on LINE Messaging becomes complex when users speak different languages. Hiring polyglot agents is expensive and hard to scale. The result: long response times, frustrated clients, and missed opportunities in international markets.

Main negative impacts:

  • High operational costs: Maintaining support teams for every target language significantly impacts your profit margins.
  • Poor response times: Manual translation tools slow down your agents, directly hurting your Net Promoter Score (NPS).
  • Degraded customer experience: An inaccurate or foreign-language response creates friction that drives users away from your brand.

Swiftask allows you to deploy intelligent AI agents fluent in dozens of languages. They handle LINE Messaging queries in real-time, ensuring seamless and personalized assistance.

BEFORE / AFTER

What changes with Swiftask

Traditional support

A customer asks a question in Japanese. The agent doesn't speak it, must translate, write a reply, translate back, and send. The customer waits 15 minutes. The experience is slow and impersonal.

Support powered by Swiftask

The customer sends a message in Japanese. The Swiftask AI agent detects the language, analyzes the query, generates a precise Japanese reply, and sends it instantly on LINE. The customer gets help in seconds.
