NB2 Hub vs Patrivox

Faithful text + image remix

This feature allows users to upload a reference image alongside a short prompt, preserving the original layout and lighting while enhancing details and texture. It is ideal for tasks such as UI iterations, product shots, and comic panels.

Crisp text inside images

With the ability to generate clean and legible on-image text, this feature ensures that multilingual typography appears without any blur or halo. It is perfect for creating posters, advertisements, and social media covers that require clear messaging.

Grounded to real-world facts

This feature leverages world knowledge and retrieval grounding to visualize accurate data, places, and styles in images. This ensures that the visuals produced are not only beautiful but also truthful and informative.

Multi-reference fusion & identity consistency

Users can fuse multiple references while maintaining consistency in characters, products, and brand elements across different shots. This is particularly useful for creating storyboards and multi-angle product showcases.

Next-Generation AI Processing

Patrivox begins with powerful, automated processing. Users can drag and drop hundreds of PDF files at once. The platform then uses Mistral AI's advanced OCR technology to accurately extract text from every page. Beyond simple text reading, it automatically performs Named Entity Recognition (NER), identifying and tagging key information such as people, locations, organizations, and dates. This foundational step enriches document metadata and prepares the entire collection for intelligent exploration without any manual data entry.

Intelligent Search and AI Chat

Once processed, finding information becomes straightforward. The platform offers a full-text search across the entire document collection that understands and tolerates typing mistakes. For more complex inquiries, users can ask questions using natural language in an AI chat interface. The AI analyzes the documents and provides precise answers, always citing the source pages it used. This feature transforms the archive from a pile of documents into a conversational knowledge partner that delivers specific results in seconds.

Interactive Knowledge Graph

This feature visually reveals the hidden connections within your archives. Every person, place, and organization identified by the AI is plotted as a node in an interactive graph. Users can navigate from one entity to another, seeing which documents mention them and how different entities are linked together. This "Constellation" view allows for the discovery of relationships and patterns that would be nearly impossible to find through manual reading, offering a new perspective on historical and archival data.

Sovereign European Hosting

Security and data sovereignty are built into Patrivox's foundation. The service is hosted exclusively on servers within the European Union. It is designed to be fully compliant with the General Data Protection Regulation (GDPR) by default. This ensures that sensitive archival documents and the data extracted from them remain under strict European data protection laws, providing crucial peace of mind for public institutions and organizations handling historical or personal information.

Graphic Design and Marketing

NB2 Hub is an excellent tool for graphic designers and marketers looking to create eye-catching visuals. With its ability to generate high-quality images quickly, users can produce promotional graphics, advertisements, and social media posts that stand out.

Educational Content Creation

Educators and content creators can utilize NB2 Hub to develop engaging educational materials. The tool's accurate rendering of information allows for the creation of infographics, diagrams, and visual aids that enhance learning experiences.

Product Mockups and Branding

Businesses can leverage NB2 Hub for branding and product mockups. The platform enables users to apply logos and patterns onto 3D objects, creating realistic and visually appealing representations of their products for marketing purposes.

Storyboarding and Visual Narratives

Writers and filmmakers can use NB2 Hub for storyboarding and constructing visual narratives. The ability to maintain character consistency across images allows for cohesive storytelling, making it easier to visualize scenes and character arcs.

Municipal and City Archives

City archives can use Patrivox to digitize and organize historical records such as council deliberations, civil registers, property records, and official correspondence. The platform makes these documents instantly searchable for city employees, historians, and citizens. This improves administrative efficiency and fulfills mandates for public transparency by making civic heritage accessible online without compromising document security or data sovereignty.

Historical Societies and Associations

Historical societies often manage collections of bulletins, newsletters, photographs, and research papers. Patrivox allows them to upload these materials in bulk and create a searchable portal for their members and the public. Volunteers are freed from the burden of manual indexing, and the AI-powered knowledge graph can help researchers uncover new historical narratives and connections within the society's own collections.

Heritage Libraries and Special Collections

Libraries with special collections, rare books, or local history archives can use Patrivox to open these resources to a wider audience. Instead of fragile documents being handled physically, patrons can search the full text and ask questions of the AI. This protects the original materials while vastly improving discoverability, supporting academic research and fostering greater public engagement with cultural heritage.

Religious and Parish Archives

Dioceses, parishes, and other religious institutions hold valuable historical documents like parish registers, baptismal records, and ecclesiastical correspondence. Patrivox provides a secure way to preserve and index these often delicate documents. It enables genealogists and historians to search for names, dates, and locations efficiently, while the institution maintains full control over access and data management within a European legal framework.

Patrivox is a foundational software platform designed to solve a basic but critical problem: making large collections of scanned documents useful. Many organizations, such as municipal archives, historical societies, and heritage libraries, possess vast archives of PDFs that are effectively locked away. These documents are difficult to search through, requiring hours of manual effort to find specific information. Patrivox addresses this by applying modern artificial intelligence to transform these static files into a dynamic, searchable knowledge base. At its core, the platform uses advanced Optical Character Recognition (OCR) powered by Mistral AI to read every word in your documents. It then goes further by automatically identifying and linking key entities like people, places, organizations, and dates. This process creates a connected web of information, or a knowledge graph, from your archives. The main value proposition is simple: it turns inaccessible data into easily searchable knowledge. Users can find information in seconds using a typo-tolerant search or by asking questions in plain language, with the AI providing answers directly sourced from the documents. Built and hosted entirely in Europe, Patrivox is a sovereign solution focused on empowering organizations to preserve and open their heritage to researchers, teams, and the public.

What is the "AI query" limit in the pricing plans?

An AI query is counted each time you use the natural language chat feature to ask a question about your documents.

The standard full-text search, browsing the knowledge graph, and filtering documents do not count as AI queries. Plans include a monthly allowance of these queries.

The platform is built to be GDPR-native, meaning it adheres to Europe's strict data protection regulations by design. You retain full ownership of your documents and the data extracted from them, and access is controlled through secure administrator and reader accounts.

Can I collaborate with others on a Patrivox archive?

Absolutely. Patrivox includes shared access features. You can designate multiple administrators to help manage the archive. Furthermore, you can grant "reader" access to an unlimited number of users, such as researchers, team members, or the public. This allows for controlled collaboration and makes it easy to share your newly searchable knowledge base with exactly the audience you choose.
