It depends on your needs. For multi-channel (WhatsApp/IG/FB/web) 24/7 auto-replies with customer data kept in your own environment, consider a self-hosted AI CS agent such as MOKAGI (from HK$299/mo). If ticketing matters, pair with Zendesk or Freshdesk. For a low-budget FAQ bot, WhatsApp Business API or a chatbot add-on works.
Three main routes: a self-hosted AI CS agent (data stays home), a cloud helpdesk SaaS with AI suggestions, or basic auto-reply via WhatsApp Business API / chatbot add-ons. Most SMEs see the fastest results starting with FAQ auto-replies.
With a ready-made platform, roughly 3 to 7 days from building the knowledge base to connecting WhatsApp/IG/FB, then ongoing tuning.
Mainstream large language models handle Cantonese and Traditional Chinese, but reply quality depends on building a knowledge base from your real company data and setting the tone.
Self-hosted solutions keep conversations and customer data in your own environment, making PDPO compliance easier. With cloud SaaS or cloud model APIs, data handling is governed by the vendor's terms.
You can greatly reduce this by using a real knowledge base, setting 'hand over when unsure' guardrails and enabling operation logs. Pricing, refunds and legal commitments should always go to a human.
