Feature Comparison
NB2 Hub
Faithful text + image remix
This feature allows users to upload a reference image along with a short prompt, enabling the Nano Banana Pro to maintain layout and lighting fidelity while enhancing details and textures. It is particularly advantageous for UI iterations, product shots, and comic panels, ensuring that the essence of the original content is preserved.
Crisp text inside images
Users can generate clean and legible text within images, ranging from headlines to entire paragraphs. This feature supports multilingual typography and avoids blurring or halos. It is ideal for creating visually appealing posters, advertisements, and social media covers that require high-quality textual integration.
Grounded to real-world facts
With the ability to leverage world knowledge and retrieval grounding, this feature ensures that generated images accurately visualize data, places, and styles. It strikes a balance between beauty and truthfulness, making it invaluable for educational content, infographics, and any context where factual representation is essential.

Patrivox
Next-Generation AI Processing
Patrivox utilizes Mistral AI to provide superior document intelligence. Upon upload, the system performs advanced OCR to accurately extract text from even challenging historical documents. It then automatically applies Named Entity Recognition (NER) to identify and tag key entities such as individuals, locations, and organizations. This dual-layer AI processing forms the foundation for all search and discovery features, transforming raw scans into structured, analyzable data without any manual configuration or data entry required from the user.
Intelligent Search & AI Chat
The platform offers a multi-faceted search experience. Users can perform instant full-text searches across the entire collection with built-in typo tolerance. For more complex inquiries, the integrated AI chat allows users to ask questions in plain language (e.g., "What was discussed about the cathedral renovations in 1830?"). The AI synthesizes information from across the documents and provides concise answers, each meticulously cited with direct links to the source pages, ensuring verifiability and trust in the results.
Interactive Knowledge Graph (Constellation)
This feature visually maps the connections between entities extracted from the documents. Every person, place, and organization becomes a node in an interactive graph, showing how they are interlinked through the archival material. Users can navigate this "constellation" to discover non-obvious relationships and contextual connections that would be nearly impossible to find through manual review, offering unprecedented insight into the social and historical networks within the archives.
Sovereign European Hosting & Security
Patrivox is built with data sovereignty as a core principle. All data is 100% hosted on servers within the European Union, ensuring compliance with strict GDPR regulations by design. The platform includes robust security features such as detailed audit logs and provides flexible, secure sharing options, including unlimited read-only access for researchers or the public, managed by a configurable number of administrators.
