Question 1

How long does it take to set up?

Accepted Answer

It only takes about 5 minutes — just embed a script tag on your site. With WordPress, simply install the plugin for an even easier setup. Preparing your knowledge base takes around 30 minutes if your FAQs are ready.

Question 2

Can I use it without technical knowledge?

Accepted Answer

Absolutely. The dashboard is intuitive and easy to navigate, and you can upload knowledge base items with drag-and-drop. With the WordPress plugin, no code editing is required at all.

Question 3

Can I migrate from an existing chatbot?

Accepted Answer

Yes! If your current solution supports CSV/JSON export of FAQ data, you can easily import it. Chat history can't be migrated, but knowledge base migration is seamless.

Question 4

How accurate are the AI responses?

Accepted Answer

The free plan uses Google Gemini 2.5 Family, while Pro plans and above use the latest Gemini 3 Family combined with RAG technology, achieving an average 78% auto-resolution rate. Higher quality knowledge bases lead to even better accuracy. When the AI isn't confident, it says "Let me check with our team" so a human can follow up.

Question 5

How many languages are supported?

Accepted Answer

The free Starter plan supports Japanese only. Pro plans and above support all 100+ languages covered by Google Gemini (English, Chinese, Korean, French, Spanish, German, Portuguese, Thai, Vietnamese, and more), with automatic language detection and response.

Question 6

What industries is it suitable for?

Accepted Answer

Chat Saku is ideal for any industry that requires customer interaction, including tourism & travel, real estate, hotels & accommodations, food & beverage, professional services (law firms, tax accountants, etc.), and e-commerce. It's especially popular with businesses looking to serve inbound tourists, as Pro plans and above support 100+ languages.

Question 7

What can I do with the free plan?

Accepted Answer

The Starter plan (free) includes 20 conversations per month, 1 small knowledge base, Japanese-only support, and website widget embedding. Start with the free plan and upgrade whenever you need.

Question 8

Can I cancel anytime?

Accepted Answer

Yes, you can cancel at any time. For monthly plans, cancel before month-end and you won't be charged the following month. For annual plans, a prorated refund is issued for the remaining period. There are no lock-in periods.

Question 9

How much is the annual discount?

Accepted Answer

Annual billing saves you 20% compared to monthly billing. You can switch back to monthly at any time, even during an annual subscription.

Question 10

How secure is my data?

Accepted Answer

All data is stored in Google Cloud's Tokyo region and fully isolated from other tenants. Communications are encrypted with TLS 1.3, and data at rest is encrypted with AES-256. We comply with Japan's Act on the Protection of Personal Information (APPI), and data deletion is available upon request.

Question 11

Does the AI use my data for training?

Accepted Answer

No. Your chat data and knowledge base data are never used to train AI models. Data is used solely for providing the service.
