Questions about Nakaryu RAG? We have answers

FAQ

What does Nakaryu RAG include?

Nakaryu RAG is a managed RAG‑LLM‑subscription: Every month we deliver a concrete module that improves your AI knowledge base – from micro‑use‑cases to complex internal AI assistants.

Which knowledge sources can you connect?

Depending on the package, you receive per month a micro‑, simple, medium, or complex RAG‑module – including coordination, implementation, testing, handover, and ongoing support within the package scope.

How quickly is the first assistant live?

Typical sources are internal docs/wikis, files, ticket systems, CRM notes, product documents, SOPs, or onboarding materials – always tailored to your permissions, terms, and responsibilities.

Can you revise existing AI or chatbot setups from us?

Yes. We can take over, clean up, and improve existing knowledge bots or RAG‑setups – or set up completely new ones. The goal is always: transparent, stable, and helpful in everyday use.

Do you only build doc chats or truly individual internal AI assistants?

Yes. Every solution is individually built on your content, sources, and rules – we do not deliver one-size-fits-all bots. Depending on the package, rights/area logic, quality checks, or API integrations are possible within the defined scope.

Are the answers stable and comprehensible?

Yes. We implement RAG so that it works reliably in everyday use – including tests, source referencing, handover, and (depending on the package) logging or quality controls.

Do your RAG‑ assistants also use AI features beyond simple retrieval?

Yes, when sensible. We use AI pragmatically: e.g., for summaries, categorization, text drafts, or prioritization. No gimmicks, but functions with benefits, clear rules, and clean integration.

Can my team understand the system after the handover?

Yes. You receive a clear handover and, if desired, a brief documentation so your team knows which sources are used, how answers are generated, and how the system is structured.

Are tool costs (LLM/API/hosting/vector database) included in the price?

Tool and license costs are not automatically included (e.g., LLM API, vector database, hosting, documentation tools). We advise you on which components are necessary and keep the setup as lean as possible.

Are maintenance and adjustments included?

Yes. Ongoing support is included in the subscription: We adjust sources, rules, and answers when content changes and fix issues within the package scope.

Can you connect our existing knowledge sources and tools?

Yes. We can connect systems like Wiki/Drive, ticketing, CRM, newsletter tools, calendars, or databases. If the effort is greater, we recommend the appropriate package or a preliminary roadmap.

What does Nakaryu RAG cost?

RAG is a monthly subscription with clear packages. You have predictable costs and receive a module each month that fits your package scope.

Are there hidden costs?

There are no hidden costs in the subscription. External tool/license/API costs only occur if they are necessary for your use case – which we transparently coordinate with you in advance.

Can I cancel or change RAG monthly?

Yes. You can switch, upgrade, or add additional use cases in the appropriate scope monthly.

What happens upon cancellation?

If you cancel, your external tool accounts naturally remain with you. Whether and how we hand over setups/accounts depends on the system used. We document your RAG‑ setup so you can continue it internally or with another partner. Not included are 24/7 emergency support, legal review, or comprehensive system changes.

Are later expansions or additional use cases possible?

Basically yes – within the booked package. If you want to tackle multiple knowledge areas in parallel, you can add additional modules in the appropriate scope at any time. Priorities are transparently coordinated with you.

How are tool licenses and additional costs handled?

For some components, we use existing licenses or standard setups. If additional licenses, data source connectors, or API accounts are necessary for your use case, these costs are passed on 1:1 – always after prior approval.

Do I need an upgrade for tools/hosting with high volume?

Usually, a lean setup is sufficient. If many documents, queries, or users are added, an upgrade of tools/hosting may be advisable. We show you transparently when it is necessary and what options are available.

Can you also use RAG for support and customer inquiries?

RAG focuses on knowledge access and internal assistance. If you want, we can also connect the assistant with forms, CRM notes, support tickets, or reporting – so questions are properly processed and information becomes reusable.

Can you link our channels with the knowledge assistant?

Yes. We can connect data and processes with your channels (e.g., website forms, email, calendar, chat, ticketing) and ensure that questions automatically flow into the right systems.

Do you also support documentation and content flows with AI?

Yes. For example, we can generate drafts from bullet points, pre-structure content, or create summaries from forms – always as part of a meaningful workflow, not as a „AI does everything automatically“ promise.

Does RAG also help with processes around sales and communication?

RAG is not an advertising service but can help operationally: e.g., knowledge modules for sales, response templates, internal enablement FAQs, or analyses of top questions. This makes communication more consistent and faster.

Is there support after implementation?

Yes. You have support in the subscription: We help with questions, maintain sources/rules, and fix issues within the package scope – with clear, straightforward communication.

What happens if the assistant provides wrong or no answers?

Then we analyze the cause, correct retrieval/sources or answer logic, and stabilize the setup. In case of external disruptions (e.g., API outages), we assist with assessment and build more robust fallbacks if sensible.

Are there backups or safeguards?

Yes – depending on the system, we implement sensible versioning, backups, and recovery paths. Important: Data backups and retention also depend on your tools.

Can I request changes or new use cases at any time?

Yes. You can submit changes or new ideas at any time. We prioritize together and implement the next RAG‑module in the next monthly loop.
