Reliable Medical Insights.
Zero AI Hallucinations.
Precise data for Healthcare.
Leonata AI for Healthcare - Desktop system
For Healthcare professionals Concerned About Privacy and Patient Confidentiality
Every patient’s history matters. Whether you’re analyzing medical records, tracking hospital safety reports, or identifying patterns in clinical data, drug discovery you can’t afford unreliable AI-generated results. LLMs don’t guarantee accuracy, and cloud-based models introduce security risks.
That’s why we built Leonata.
A deterministic knowledge graph solution that runs offline—so your hospital, lab, or research facility maintains full control over patient data.
✔️ Analyze patient records securely – No cloud, no risk of data leaks
✔️ Spot trends in medical safety – Quickly query structured insights across millions of cases
✔️ Eliminate AI bias – Knowledge graphs built from your data, not a general-purpose model
Medical data requires precision. Leonata delivers.

Case study
Ray works in the Defence Industry, every week there are Requests for tender pushed out from the Federal Government, they call out specific legislation and often ask the same question in different ways and require the same information across various sections. They require accuracy and their success drives the income of the organisation.
Ray - Head of Software Development, Defence Industry, Australia and United States
“Every single tender document is written by a different person with different language, plus within the one document there is information from the finance, engineering and IT depts, each with their own way of describing things.
Leonata let me accurately map between the documents and cut through the same concept being described in different ways.”
Who is it for?
In-house Counsel
You are working on a project that requires analysis of internal classified documents that contain highly sensitive personal information. You need to target a specific area of case law and transpose it against your companies internal policies and procedures plus review previous company responses and learnings, Leonata can be offline and secure, with a fixed monthly cost, it seems to be the perfect fit
AI Pipeline Architect
You have 5-10 pieces of kit strung together to feed data into this app for your client. You’re a contractor and you pay for the tools that save you time out of your own personal pocket. You don’t want to add another, but you see that Leonata will streamline your tasks and reduce your daily workload. Plus eliminate two other monthly costs, and not add compute costs, win win.
Software Engineer
So you’ve heard of Retrieval-Augmented Generation (RAG) and Graph-RAG but you are still starting with contaminated data. Your first point of call is still the LLM and you can’t be sure what the source was and who trained the model. Your client needs an app developed for their customers health data and they need it yesterday, Leonata.
Developer
You spend 3-5 days liasing with your client over each new piece of data you’re running through their new app. It’s come through three LLM’s and you don’t have a medical background so you’re on the phone with them and emailing constantly. They start to question whether ongoing token costs will be sustainable in their business model and launch of the app stalls…you remember Leonata. You’re able to use the terminal to add the critical step and save yourself time and the client money.
Data Analyst
You want to use an LLM to collate the internal risk and compliance records for the mining company you work for but there is a ban on ChatGPT and the internal LLM is still months away, plus you’ve heard it’s just ChatGPT in a skin…you know that Leonata is entirely offline and will comply with your IT dept security policy, plus the finance department will love the fixed monthly cost, no token blow outs.
Health Researcher
You have over 5 million data points for over 200,00 patients which visit your local hospital. The administrator has tasked you with locating which conditions receive the most safety issues for the hospital, how do you complete this task in three months with almost no budget? Leonata of course.
Introducing The Optimum Language Model
Precision Without Hallucination
We have designed a pure, closed system that builds a semantic and syntactic understanding of your text without external influence. Instead of relying on a general-purpose AI that frequently bring in false data, Leonata creates a model that:
Indexes your data based on meaning and structure, not just keyword matches
Preserves contextual relationships between terms without bias from unrelated sources
Generates knowledge graphs that actually reflect how your specific dataset is structured
This means your results are always relevant, reliable, and free from data contamination.
Join our Betas Today and Experience the Next Generation of Knowledge Graphs.
Leonata is in limited beta, and we're looking for clinical and healthcare professionals to test it in real-world scenarios. This is your chance to:
✔ Be first to deploy an airgapped, deterministic AI pipeline
✔ Shape the future of knowledge graphing with direct feedback
✔ Eliminate reliance on unreliable external models
No Hallucinations. No Surprises. Just Reliable Results.
No hallucination
Discrete system. Ensures 100% accuracy by grounding every answer in the provided dataset.
Eliminates risks associated with LLM misinterpretations or creative extrapolation.
On-Demand Knowledge Graphs
Builds a new, dedicated knowledge graph for every new query.
Maximizes precision and relevance by tailoring insights to the exact context of each question.
Security and Privacy
Operates entirely offline—ideal for air-gapped or high-security environments.
Only processes user-provided data, ensuring zero external interference or risk of data leaks.
Efficiency and Scalability
Requires minimal compute resources, making it cost-effective and deployable on edge devices.
Suitable for industries with constrained infrastructure or where high compute costs are prohibitive.
Custom Thesaurus Creation
Dynamically builds and relies on a custom thesaurus based solely on the user's dataset.
Avoids dependency on pre-trained models, ensuring domain-specific and uncontaminated contextually accurate results.
No Training Needed
Skips the expensive, time-consuming process of model training.
Ready to deploy now and deliver insights immediately upon integration.

“Our semantic knowledge graph builder redefines AI efficiency. Unlike traditional RAG or LLMs, it avoids hallucination entirely, builds custom knowledge graphs for each question, works securely offline, requires minimal compute power, and uses only your data—no external influence, no training required."
Leonata
-
Healthcare professionals spends hours, days and weeks verifying and validating data. Contacting the patient or medical team as the technical, local knowledge expert repeatedly can become laborious and onerous. Natural Language Processing is a science that we have built into Leonata via a semantic model so you can build accurate knowledge graphs from huge datasets in seconds. Having patient surveys, journal articles or PRIMs and PROMs available for analysis in a secure on-site location.
-
It’s light. Depending on what you feed it, Leonata can run on a phone or a basic laptop. Add a GPU if you need but this is light, efficient AI so you’ll save money on those NVIDIA chips..
Government funded organisations have budgets around IT infrastructure and Leonata is affordable and nimble.
-
If the nature of your project requires you to be air-gapped that is possible with Leonata, our default package calls out for license validation purposes, but we can give you access to an entirely offline product. Zero cloud hosting and zero risk. You store your data where it is secure and you control all access. We never see or store your data, it’s your business.
-
All AI today is trained. Training means a select group of humans once upon a time sat in a room and determined the meaning of words and concepts or a web crawler scraped wikipedia articles to build a thesaurus and a subsequent model. You have zero insight into what built that model and who trained it. The LLM can deteriorate in front of your very eyes.
Make your own knowledge graph that is specific to your industry and your know how, using language in the way you intended. Use Leonata’s semantic model to build a Knowledge Graph just for you, relevant to your patient cohort.
