NB2 Hub vs Patrivox

Faithful Text and Image Remix

This feature allows users to upload a reference image along with a brief prompt. The Nano Banana Pro preserves the original layout and lighting while enhancing details and textures. This is particularly useful for UI iterations, product shots, and comic panels.

Crisp Text Inside Images

With this feature, users can generate clear and legible text over images. It supports multilingual typography without any blurring or halo effects. This is ideal for creating visually appealing posters, advertisements, and social media covers.

Grounded to Real-World Facts

Leverage the power of world knowledge and retrieval grounding to create images that visualize accurate data, places, and styles. This feature ensures that the generated visuals are not only beautiful but also truthful, making it perfect for educational content and infographics.

Multi-Reference Fusion and Identity Consistency

This feature enables the fusion of multiple references while maintaining consistency in characters, products, and brand elements across various images. This is especially beneficial for storyboards and multi-angle product sets, allowing for a cohesive visual narrative.

Next-Gen AI Automation

Patrivox eliminates manual data entry through fully automated processing. Users can drag and drop hundreds of PDFs in a batch, and the platform's integration with Mistral AI handles the rest. It performs advanced optical character recognition (OCR) to extract every word, then automatically identifies and classifies key entities such as names, locations, dates, and organizations. This process enriches document metadata without any human configuration, turning a backlog of scans into a structured database in minutes.

Intelligent Search & AI Chat

Moving beyond simple keyword matching, Patrivox offers a multi-faceted search experience. It provides instant full-text search across the entire collection with typo tolerance, ensuring robust results. Users can also filter searches by date, author, or document type. Most powerfully, the platform features an AI chat interface where researchers can ask complex questions in natural language. The AI then provides concise answers, complete with citations back to the exact source documents, blending the depth of archives with the simplicity of a conversation.

Interactive Knowledge Graph (Constellation)

This feature visualizes the hidden narratives within archives. By automatically identifying and linking every person, place, and organization mentioned across all documents, Patrivox builds an interactive knowledge graph called "Constellation." Users can navigate visually from node to node, discovering relationships and connections between entities that would be exceedingly difficult to uncover through traditional linear document review, revealing the social and historical fabric woven through the records.

Sovereign European Hosting & Sharing

Built with European data sovereignty as a cornerstone, Patrivox is GDPR-native and hosted exclusively on servers within the European Union. This provides crucial legal and ethical compliance for public institutions handling sensitive historical data. Furthermore, the platform includes robust sharing capabilities, allowing administrators to grant unlimited read-only access to researchers, team members, or the public, facilitating collaboration and open access without compromising administrative control.

Marketing Campaigns

Marketers can utilize NB2 Hub to create eye-catching visuals for campaigns, enhancing engagement through high-quality images that convey their brand message effectively. The ability to generate crisp text and imagery makes it a powerful tool for advertisements.

Municipal Archives Digitization

City and town archives can use Patrivox to digitize and bring to life decades of council deliberations, civil registers, property records, and official correspondence. The platform makes these documents instantly searchable for clerks and historians, while the public-facing sharing options allow citizens to explore their local heritage, fulfilling transparency and cultural preservation mandates efficiently.

Historical Society Collections Management

Historical societies often manage extensive collections of bulletins, newsletters, photographs, and personal papers from donors. Patrivox enables small teams or volunteers to process these collections at scale, making every name and event searchable. The knowledge graph helps uncover biographical links and local historical networks, empowering societies to create compelling digital exhibitions and research resources.

Parish and Diocesan Record Preservation

Dioceses and parish archives hold fragile registers of baptisms, marriages, and burials that are vital for genealogical and historical research. Patrivox provides a secure, European-hosted solution to digitize these records. The powerful OCR handles varied handwriting, and the entity extraction automatically identifies names and dates, creating a priceless searchable index for family historians and academic researchers alike.

Special Collections in Heritage Libraries

Libraries with special collections of manuscripts, rare books, or thematic archives can use Patrivox to lower the barrier to access. Instead of requiring in-person visits and manual catalog searches, scholars worldwide can query the AI chat or explore the knowledge graph to identify relevant materials remotely. This amplifies the research impact of the collection and protects physical originals from excessive handling.
