OpenIntelligence
Offline Neural RAG Engine
Free · In‑App Purchases · Designed for iPad
On-device RAG engine for iPhone. 29-step pipeline, 7 anti-hallucination gates, 3 quality modes. Import PDFs, Word, Excel, images - ask questions, get cited answers.
Turn your documents into an offline neural knowledge base - entirely on your iPhone.
OpenIntelligence is an on-device RAG engine that imports your documents, builds a local search index, and answers questions using Apple Intelligence. No cloud. No accounts. No data leaves your device.
RETRIEVAL (29-STEP PIPELINE)
• Hybrid Search — BM25 keywords fused with 384-dim neural embeddings via RRF
• HyDE — Synthetic answer generation for better semantic matching
• Cross-Encoder Reranking — Neural model rescores candidates for precision
• MMR Diversification — Filters redundant chunks for maximum coverage
• Parent Document Retrieval — Expands matches to surrounding paragraph context
• Graph Context Packing — Optimizes the 4,096-token budget via graph algorithms
• Lost-in-Middle Mitigation — Reorders evidence so the AI sees critical content first
DOCUMENT PROCESSING
• Semantic Chunking — Splits by logic and structure, not character counts
• Multi-Column OCR — Metal-accelerated Vision at 360 DPI for complex layouts
• Font Cipher Detection — Detects encoded text and forces full OCR
• Entity Extraction — Names, organizations, technical terms indexed per document
ANTI-HALLUCINATION (7 GATES)
Every answer passes gates A-G: retrieval confidence, evidence coverage, numeric sanity, contradiction detection, semantic grounding, quote faithfulness, and generation quality. Critical failures trigger abstention — the app refuses to answer rather than answer wrong.
When questions barely overlap with documents, Evidence-First Mode states what evidence exists instead of fabricating answers.
THREE QUALITY MODES
• Standard — Fast factual answers in seconds
• Deep Think — Multi-step reasoning steps with iterative retrieval for legal, medical, or academic research
• Maximum — As many steps it takes to reach 98% confidence with exhaustive multi-chain synthesis
AI HUB TRANSFORMS
Extract Key Facts, Step-by-Step, Plain English, Gap Analysis, or Illustrations from any answer — grounded in source documents with markdown rendering.
AGENTIC TOOL USE
8 tools the AI invokes automatically: semantic search, document listing, summarization, pattern counting, exact text search, corpus statistics, related documents, and cross-document comparison.
PERFORMANCE & TELEMETRY
3-tier Metal GPU shaders and concurrent neural reranking adapt to your Apple Silicon. Motherboard HUD shows real-time chip telemetry: thermal, memory, GPU utilization.
100% PRIVATE
Runs on-device via Apple's Foundation Models. Documents never leave your iPhone unless iOS invokes Private Cloud Compute — Apple's zero-retention, cryptographically verified fallback. No accounts. No uploads. No tracking.
