Isidorus Hispalensis

Isidorus Hispalensis is a personal document management system that harnesses the power of modern artificial intelligence while keeping your documents private. Document analysis and AI processing happen locally on your iPad. By default, your files are never uploaded to the cloud. PRIVATE BY DESIGN - Document and AI processing run locally on your device - Your documents, prompts, queries, AI responses, file names, and file paths are never collected - No accounts or registration required - Core features work offline - Optional anonymous telemetry may be used only to improve performance, stability, and features AI DOCUMENT TASKS - Summarization: Generate concise summaries of any document - Translation: Translate entire documents to multiple languages - Presentations: Automatically create slides from your texts - Q&A: Get precise answers about document content - Rewriting: Transform documents with custom instructions - Chat with your documents naturally INTELLIGENT SEMANTIC SEARCH Ask questions in natural language about your document library. The RAG agent finds and synthesizes information from multiple files to give you complete answers, and Deep Research mode digs deeper for thorough, multi-source results. CONVERSATIONAL ASSISTANT Ask general questions even without adding documents. The built-in conversational agent draws on a bundled knowledge base of reference articles (a selection of Wikipedia) and understands your questions in your own language. ENTITY EXTRACTION Automatically categorize your documents by people, organizations, and locations mentioned. Build a knowledge graph from your document collection locally on your iPad. PDF UTILITIES - Merge multiple PDFs into one - Extract specific pages from documents - OCR to extract text from scanned documents SUPPORTED FORMATS PDF, Word (.docx), Excel (.xlsx), PowerPoint (.pptx), EPUB, plain text, RTF, and Markdown. Export to Word, RTF, Markdown, PowerPoint, and EPUB. Read EPUB ebooks directly in the app. MULTILINGUAL Isidorus speaks your language. Available in 28 languages — including English, Spanish, Chinese (Simplified and Traditional), Hindi, Arabic, Bengali, Portuguese, French, German, Russian, Japanese, and Korean — the assistant understands your questions in your own language. OPTIONAL CLOUD MODELS Want extra power? Optionally connect OpenAI-compatible cloud providers and choose the right model for each task. This is entirely optional — local processing stays the default, your API keys are stored securely in your device's keychain, and nothing is sent anywhere unless you connect a provider. ANONYMOUS TELEMETRY Optional anonymous telemetry may be used to understand app performance, errors, crashes, and feature usage. Telemetry is used strictly to improve the app and its features. It does not include Personal Identifiable Information, document contents, file names, file paths, search queries, chat messages, AI prompts, or AI responses. Telemetry is not sold and is not shared with third parties for advertising, profiling, or cross-app tracking. FREE AND UNLIMITED No subscriptions, no quotas, no usage limits. All features are included because document and AI processing run on your own hardware. Named after Isidore of Seville, the medieval scholar considered the first encyclopedist, this app continues his legacy of knowledge organization in the digital age. Requirements: iOS 18 or later, Apple Silicon, 6GB RAM minimum.
