The same foundation in every planOne price per knowledge base,
One price per knowledge base,
whatever its technology.
Find · Vector RAG
Search the relevant passages in your documents and trace them back to their sources.
Structure · LLM wiki
Organise your knowledge into connected topics you can reuse.
Protect · Encrypted anonymisation
Apply protection to the supported information before certain AI processing. The scope is confirmed with you.
Model choice, internal assistants and chatbot publishing are available in every plan. The €20 supplement for a protected knowledge base is gone.
Processing — search, wiki generation, protection, import or synchronisation — consumes NrTok according to its rate. Storage limits and available connections are specified before activation. Access to a technology does not guarantee that every piece of content stays invisible to the model.
Your configuration
What does a knowledge base cost for your organisation?
Prices per additional knowledge base and per additional user go down as the plan grows. The calculator compares all three.
One knowledge base can hold several documents and feed several use cases. Each additional base adds 50,000 NrTok per month to the shared budget. An additional user adds no NrTok. Top up your budget separately if you need to.

1 NrTok represents €0.0001 of credit usable inside Narratheque.
Your balance covers AI answers and the preparation of your knowledge: imports, wiki generation and protection processing.
What an operation costs depends on the model, the volume processed and the task. A NrTok is neither a technical model token nor a guaranteed answer.
A budget you keep control of
- 50,000 NrTok included = €5 of usage.

Included NrTok are renewed every month and carry over for the whole duration of the subscription. On annual billing, the credit is granted every month across the 12 months, including the 2 free ones. Top-ups are deliberate, with no automatic overage.
A usage unit specific to the platform, with no investment value and no conversion into money. NrTok remain usable for the whole duration of the subscription. The rate for each operation will be specified before you subscribe.

Frequently asked questions
What you want to know about the cost of a knowledge base.
What changes between Simple, Pro and Max?
The number of knowledge bases, the number of users, the included NrTok budget and the price of additional capacity. A vector, wiki or protected base costs the same within a given plan. What a knowledge base costs therefore depends on the plan you choose, not on the technology behind it.
Do I need a new knowledge base for every document?
No. A knowledge base gathers what a trade or an audience needs to know. Several sources can feed the same base. Separate your bases when access rights or knowledge need to stay distinct.
Is a more expensive technology free?
Access to it carries no monthly supplement per base. The operations it requires consume NrTok according to their processing cost and the published rate.
Can I buy usage only?
Yes. You can top up NrTok while keeping your plan. A busier chatbot does not force you to buy more user seats. What a knowledge base costs stays predictable: the plan does not move, only usage follows your activity.
What is still charged on top?
Bases and users beyond the plan, top-ups, support, specific integrations and dedicated environments. Storage volumes, synchronisation frequencies and technical limits are to be confirmed before you commit.
Can an agency split Max across its clients?
Plans apply to a single organisation. Each client has its own workspace and its own subscription. A partner can support several organisations through delegated access.
Need a hand getting started?
An agency or an AI lead can prepare your sources, set up your chatbot and support the team. Their services are quoted separately.
