What is Noxidox?
Intelligent Document Analysis — Entirely on Your iPhone
Noxidox is an iOS app that lets you search, analyze, and query your documents using artificial intelligence — without your data ever leaving your device. Import PDFs, Word documents, or text files, organize them into projects, and simply ask questions in natural language.
Noxidox is powered by Apple Intelligence, Apple's powerful on-device AI framework. All processing runs locally on your iPhone — no internet connection required, no external servers involved, and no privacy trade-offs. Noxidox uses this framework for fully private, AI-optimized document analysis directly on your device.

What Noxidox Can Do
Eight powerful features for intelligent document analysis — entirely on your device.
On-Device AI
Noxidox is powered by Apple Intelligence — Apple's proprietary on-device AI model, deeply integrated into the A17 Pro chip and continuously refined by Apple's own research teams. Unlike open-source models, Apple Intelligence is purpose-built for iPhone hardware: faster, more efficient, and more accurate. All processing runs locally — no cloud, no latency, no trade-offs.
Hybrid AI Search — Precise Answers from Your Documents
At the heart of Noxidox is a hybrid AI-based search that combines semantic vector search with classical keyword search. While a standard full-text search only finds exact matches, semantic search understands the meaning of your question — and surfaces contextually relevant passages even when they don't contain the exact term you used. The result: more accurate answers, less noise, and more relevant hits.
Multi-Document Projects — Search and Analyze Across Sources
Organize your documents into thematic projects and ask a single question that is answered across all documents simultaneously. Whether it's a research collection, study materials, or a contract folder — Noxidox connects relevant passages from multiple sources into a coherent answer. Projects can be expanded, restructured, and exported at any time.
Voice Input & Output — Hands-Free Interaction
With built-in voice input, you ask questions simply by speaking — fully transcribed on-device, without any audio data being sent to an external service. The voice output reads answers back to you, so your hands stay free while driving, exercising, or cooking. Noxidox uses exclusively native iOS frameworks that require no cloud connection.
PDF & Document Formats — Flexible Import Options
Noxidox supports PDFs, Word documents (.docx), and text files (.txt). Upon import, documents are automatically indexed and prepared for AI-based search. Images within PDFs are analyzed and recognized using Apple Vision, converting them into searchable content — so no information is lost, even when a document contains scanned pages.
Chat History — Revisit Your Analyses Anytime
All conversations are stored locally on your device and accessible at any time. On request, Noxidox generates an AI-powered summary of each chat session — including key insights, the sources consulted, and open questions your documents could not answer. This keeps you oriented, even when researching a topic across multiple sessions.
Chat Export as PDF & Markdown
Export any conversation with a single tap as a cleanly formatted PDF or Markdown document. Perfect for reports, meeting notes, and sharing AI-generated insights — directly from the app, no workarounds needed.
Tags & Automatic AI Classification
Assign custom tags to projects and documents — or let Apple Intelligence automatically suggest fitting tags for you. Filter your library in seconds and stay on top of your content, no matter how many documents you manage.
Your Privacy. No Compromises.
All data stays on your device — no servers, no telemetry.
What this means in practice:
- No cloud processing. The AI runs locally — on your device, with your hardware.
- No access to your content. Noxidox has no visibility into the contents of your documents or conversations.
- No tracking, no analytics. No usage data is collected or shared.
- Fully offline. Noxidox works entirely without an internet connection.
- GDPR compliant. Since no personal data is collected or transmitted, there are no privacy gray areas.
With optional iCloud Sync (Pro), projects and documents can be synchronized across your Apple devices — while remaining end-to-end encrypted and accessible only to you. Even Apple has no visibility into the synced content.
Noxidox is the answer to a question many AI users are asking: can I use modern AI features without giving up my data? The answer is yes.
For iPhone with Apple Intelligence
Noxidox requires Apple Intelligence and runs on iPhone 15 Pro, iPhone 15 Pro Max, and all newer models with the A17 Pro chip or later. iOS 26 or higher is required. The app is fully offline-capable — no internet connection is needed for either the AI or the search functionality.
