What kind of chatbot is narubot™?
+
narubot™ is a chatbot for institutions that answers only from verified material. It is installed on the institution's server, and instead of calling third-party generative AI (ChatGPT, Claude, Gemini, etc.), its in-house engine produces answers inside the institution's server.
Without external AI APIs, how does it produce answers?
+
It uses VGA (Verified Grounded Answering). It understands the question, finds evidence in pre-verified Q&As and institutional material, and answers with the source and verification date attached. If there is no evidence, it doesn't make anything up — it says it doesn't know.
Doesn't it hallucinate?
+
Because it uses only verified answers rather than generating new sentences, hallucination is structurally minimized. If no prepared answer exists, it says it doesn't know and suggests similar questions.
Do questions or internal documents ever leave the institution?
+
No. All processing is completed inside the institution's server, and nothing is sent to external AI companies or to us. Question logs store no IP addresses or account information.
Can it be used on a closed network without internet access?
+
Yes. It works without an internet connection and can be installed with the closed-network installation bundle.
Does it need a GPU?
+
No. It runs on a standard server; the minimum specification for the Lite tier is 2 vCPU · 4GB memory · 50GB SSD.
How much does it cost?
+
It is licensed as one license per institution. Lite is $8,250, Standard $13,500, and Advanced from $22,500 (suggested retail); initial tuning and annual maintenance (15% of the license price per year, starting after acceptance) are charged separately. There is no per-question token cost. All prices exclude VAT, and contracts are made through partner companies.
Can it be procured through a direct (private) contract in Korea?
+
Yes. In Korea, all standard packages fall within the range where public institutions can sign a negotiated (direct) service contract — an estimated price of KRW 50 million or less, excluding VAT. The actual contract method follows each institution's procurement rules, and contracts are made through our partner companies.
Does it support other languages?
+
English is the default, and Korean, Chinese (Simplified), Vietnamese, Japanese and Spanish can be added as options, from $3,375 per language.
What does the institution need to do itself?
+
Simply upload or send the questions, FAQs, civil-service handbooks, regulation documents and other material you have through the institution dashboard. FAQ additions and edits can also be requested from the dashboard — we verify and apply them — and you can see progress, usage and monthly reports there too. We take care of answer tuning, tone customization, regular tuning and upgrades.
Can the tone be adapted to our institution?
+
Yes. Formal or polite speech style, emojis, answer length, forms of address, greetings and the "don't know" message are all configurable, and you can preview them in the chatbot screen.
Does the service stop when content is changed?
+
Changes to answers, FAQs and tone go live immediately without a restart once they pass automated checks, and can be rolled back in one step if there is a problem. We also make every effort to carry out engine upgrades and security updates without service interruption. However, a short maintenance window may be needed in some cases, such as database schema changes or server OS patches (reboots); in that case we notify you in advance and do it during low-usage hours.
What domains can it be used for?
+
We provide demos for 7 domains: local government civil-service guidance, university academic guidance, internal regulation search, welfare counseling, education office and school civil services, library services, and daily-life guidance for foreign residents. Other domains can also be set up based on your material.
How do installation and licensing work?
+
After installing on the institution's server with a single installation script, you set the license key, institution details, operator account, chatbots to use, tone, languages and branding step by step in the web-based setup wizard. The license key is verified by digital signature only, inside the server, without internet — so it works on closed networks too. Without a key, it runs as a trial with one chatbot and Korean only.
Does the chatbot stop when the maintenance period ends?
+
No. To keep public services uninterrupted, the chatbot keeps answering; only new content deployment and upgrades require entering a renewal key. A renewal notice is shown in the admin screen.
Can it use our institution's name and logo?
+
Yes (white label). In the admin screen you can change the product name, logo, colors, favicon, footer text and the name shown on answer cards, and preview them immediately. Hiding the 'Powered by narubot™' mark is available with a white-label license.
How do I request adoption or a demo?
+
