FRIDAI vs Kufu: AI customer service features and yearly cost for small LINE, IG and FB shops

The verdict up front: which to try first

What each product is built for

FRIDAI is an AI customer service and social automation service split into three products: FRIDAI Chat handles DM customer service and human handoff, FRIDAI Social handles comment auto-⁠replies and comment-⁠to-⁠DM, and FRIDAI Post handles automatic posting. Shops maintain their brand knowledge and reply rules in Traditional Chinese, and the AI answers customers from that content.

Kufu is built around an omnichannel inbox, automation flows and customer management. The Social plan focuses on FAQ and post comment auto-⁠replies for FB and IG. Enterprise adds LINE Official Accounts, an embedded website chat, channel broadcasts, social marketing games, a CRM and 10 seats. Its AI customer service answers customers through semantic Q&A over a knowledge base; on Enterprise it is added with a yearly AI system fee, and the Custom plan includes it.

Feature comparison

Channels: LINE, IG and FB, the ones small shops use most

LINE, Instagram and Messenger, the channels Taiwan shops care about most, work on both. The difference is in how you buy them.

FRIDAI is one plan per platform account, so answering DMs on both IG and LINE means two plans, and each one includes AI replies, bookings and human handoff. Kufu Social connects one Facebook Page and one Instagram business account. Enterprise starts at one of each and adds LINE Official Account DMs, broadcasts and rich menus, plus Kufu Portal embedded on your website.

DMs on Threads, WhatsApp, Telegram and Discord are extra channels on FRIDAI, worth noting for brands with overseas customers or community accounts. Kufu's strength is putting several channels into one inbox so a team can see and answer together.

Tip: count how many messages each channel got last month and how many people answer them, then come back to this section. You will quickly see which plan fits~

AI setup: knowledge plus rules

With FRIDAI, you write your products, prices, service process and brand voice into the knowledge base in plain language, then write reply rules: what to do in which situation, what to ask first, when to quote a price and when to hand off to a person. One-⁠click scanning of posts, comments, DMs, websites and documents produces a first version of the knowledge base, so you can start testing on your own. When an overseas customer messages, FRIDAI detects the language and answers naturally, with support for more than 100 languages.

Kufu's AI customer service answers through semantic Q&A over your own knowledge base. Enterprise also includes AI tagging (automatic tags from conversation content) and AI-⁠assisted replies (translation, polishing and suggested replies, 500 a month). Teams that prefer people to reply, with AI helping polish on the side, will like this combination.

For Traditional Chinese tone on either side, testing five real customer messages is the most reliable check. To get your own material in order first, read how to write an AI customer service knowledge base.

Comment auto-⁠replies and broadcasts

Small shops often drive traffic through post comments, so this part deserves a closer look.

FRIDAI Social auto-⁠replies to comments on Instagram, Facebook and Threads and brings comments into DMs, with an AI mode and a fixed-⁠keyword mode. For the DM part, the same account needs both a Social and a Chat plan. To turn comments into a LINE list and broadcast by tag, read the LINE lead magnet guide.

Kufu has post comment auto-⁠replies from the Social plan up. It can reply in public or move the conversation to DMs, different comments can trigger different messages, and there are per-⁠comment and global settings. Enterprise broadcasts support segmented bulk sends, variables for personalization, and short links that track each recipient's clicks, with CSV export.

Human handoff and team collaboration

Every FRIDAI plan includes human collaboration and human review: when a person is needed, FRIDAI's official LINE account notifies you, sensitive replies can be reviewed before they go out, and once a person takes over, the AI steps aside. Even a one-⁠person shop can catch notifications on LINE on a phone.

Kufu Enterprise has a unified inbox, 10 seats, customer profiles with timelines, and saved reply templates. Complaints or questions the knowledge base cannot answer can go to a named agent, pausing auto-⁠replies for that conversation, once you switch it on in the handoff settings. Larger support teams with clear roles will find it well organized.

How to compare the cost: start with the billing unit

Kufu counts AI usage in conversations and FRIDAI counts replies. The units differ, so ask how a conversation is counted before you sign up. The usage in the four examples below is hypothetical; prices are each side's public list prices, used to show how to calculate:

A pattern shows up once you run the numbers: if you want AI to answer DMs directly, every FRIDAI plan includes AI and you can start monthly with one account; if you want a team inbox, broadcasts and CRM, Kufu Enterprise puts them in one yearly fee. For the full method, read how AI customer service pricing works, and for LINE Official Account message fees, read the LINE Official Account pricing guide.

One test checklist, run once on each

FRIDAI can be tested as soon as you start the US$1 trial. Kufu has a 14-⁠day free trial; for its AI customer service, bring the same material and ask the Kufu team for a demo.

Step 1: Prepare the same material

Prepare your price list or product list, opening hours, return or cancellation rules, and five real customer messages with personal details removed. Give both sides the same content.

Step 2: Run the same conversations

Scenario 1: On LINE, "How much is this?" without saying which item
Scenario 2: The need only becomes clear across three casual messages in Taiwanese Mandarin
Scenario 3: A phone number in one message, a request to change the booking in the next
Scenario 4: An IG post comment saying "I'd like to know more", which should trigger a DM
Scenario 5: A question your material does not cover
Scenario 6: A request for a discount beyond your public offers
Scenario 7: "I want a real person"; after the person replies, the customer asks something else the next day

Step 3: Score with the same table

Choose by what you need

• If you only run FB and IG and want keyword and comment auto-⁠replies to save time → look at Kufu Social, NT$5,000 a year, with a 14-⁠day trial.
• If you have a support team that needs LINE, FB and IG in one inbox, plus tracked broadcasts and customer management → look at Kufu Enterprise, adding AI customer service by conversation volume.
• If DMs chase you all day and you want to start with one account, write rules in Traditional Chinese, and let AI handle DMs, comments and bookings, with a LINE notification when a person is needed → try FRIDAI first.
