NB2 Hub vs Patrivox

Faithful Text & Image Remix

This feature lets you upload a reference image and provide a short text prompt. Nano Banana Pro intelligently preserves the original layout, composition, and lighting of your image while expertly upgrading the details, textures, and specific elements you request. It's perfect for iterating on UI designs, creating new versions of product photography, or remastering comic panels without starting from scratch, saving you hours of manual editing work.

Crisp Text Inside Images

Say goodbye to blurry, AI-generated text! NB2 Hub specializes in creating clean, legible text directly inside your images. It can generate everything from bold headlines to full paragraphs with proper multilingual typography, without any of the strange artifacts or halos common in other AI tools. This feature is a game-changer for creating professional posters, advertisement banners, social media covers, and any graphic where clear communication is key.

Multi-Reference Fusion & Identity Consistency

Need to blend ideas or maintain a character across multiple scenes? This powerful feature allows you to upload several reference images and fuse them into one coherent result. More importantly, it expertly maintains consistency for characters, products, or specific brand elements across all your generated shots. This is ideal for creating storyboards, multi-angle product sets, or ensuring a cohesive look for an entire marketing campaign.

Pro-Level Lighting & Camera Control

Take full creative control over the mood and composition of your images. This feature provides fine-tuned adjustments just like a professional photographer or cinematographer would use. You can control lens type, framing, depth of field, and color grading. Make local edits, change a scene from day to night, or add dramatic chiaroscuro lighting effects—all through simple text instructions to achieve cinematic results on demand.

Automation with Mistral AI

Simply drag and drop your PDFs, whether it's one file or hundreds in a batch. Patrivox takes over from there. Within minutes, the integrated Mistral AI engine reads every page with next-generation OCR, automatically extracts key entities (people, places, organizations, dates), and enriches document metadata. There's no manual data entry or complex configuration required. You drop your files, and the platform does the rest, turning unstructured scans into a structured database ready for exploration.

Intelligent Search & AI Chat

Find any word or phrase across your entire collection in less than a second, with smart typo tolerance so you don't need perfect spelling. You can also filter results by date, author, or document type. For more complex inquiries, use the AI chat feature. Ask questions in natural language, like "What was discussed about the cathedral in 1830?" and the AI will provide concise answers, directly citing the source documents it found the information in, making verification easy and trustworthy.

Interactive Knowledge Graph (Constellation)

This feature visually reveals the hidden connections within your archives. Every person, place, and organization identified by the AI becomes a node in an interactive graph. You can navigate from one entity to another, seeing all the documents that connect them. This allows you to discover relationships and patterns that were previously invisible, offering a powerful new way to conduct research and explore your collection's narrative.

Sovereign European Hosting & Sharing

Patrivox is built on a foundation of data sovereignty and security. All data is processed and hosted 100% within the European Union, ensuring full compliance with GDPR regulations. The platform also includes an audit log for transparency. Furthermore, it offers flexible sharing: you can have multiple administrators while granting unlimited read-only access to researchers, your team, or the public, making it easy to open your archives without compromising control.

Social Media & Marketing Content Creation

Quickly generate a constant stream of eye-catching visuals for your social media channels, email newsletters, and digital ads. Create branded posts with perfect text overlays, design multiple ad variations for A/B testing, and produce engaging infographics that explain your services, all without needing a graphic designer on standby for every single request.

Product Design & Mockup Generation

Revolutionize your product development and presentation cycle. Designers can iterate on product concepts, apply logos and patterns accurately onto 3D objects, and generate photorealistic mockups for packaging, merchandise, or online stores. This allows for rapid prototyping and client presentations, making it easier to visualize and sell a product before it's physically made.

Storyboarding & Concept Art

Filmmakers, game developers, and writers can use NB2 Hub to quickly visualize scenes and characters. Upload sketches or mood boards and use the multi-reference fusion feature to create consistent character shots from different angles. Generate entire storyboard panels with controlled lighting and composition, helping to communicate creative visions clearly to entire production teams.

Educational & Informational Graphics

Teachers, trainers, and content marketers can create beautiful, accurate educational materials with ease. Leverage the tool's grounding in real-world facts to generate correct visualizations of data, historical events, or scientific concepts. Turn dense information into easy-to-understand, visually appealing infographics, diagrams, and illustrated guides that enhance learning and engagement.

Municipal Archives

Municipalities can use Patrivox to digitize and showcase their historical deliberations, civil registers, and official correspondence. This makes decades or centuries of administrative history instantly searchable for staff and citizens, improving transparency and preserving local heritage for future generations without the need for manual indexing.

Historical Societies & Associations

Societies often have vast collections of bulletins, newsletters, and documentary collections. Patrivox allows them to upload these materials and make them fully searchable and explorable for their members and researchers. The knowledge graph helps uncover the intricate stories and connections between local figures and events featured in their publications.

Heritage Libraries & Archives

Libraries with special collections can use Patrivox to open their unique archives to a wider audience. Researchers can instantly search through rare manuscripts, historical books, or photo collections, while the AI chat helps them ask specific questions, accelerating discovery and making precious knowledge accessible without handling fragile originals.

Dioceses & Parish Archives

Religious institutions can preserve and index their valuable parish registers, ecclesiastical correspondence, and historical documents.
