About OpenIntelligence

OpenIntelligence is a dedicated, on-device document search and citation-backed Q&A engine for iPhone, iPad, and Mac.

IMPORTANT: This is not a conversational chatbot, creative writing assistant, or internet-connected search agent. It is a professional productivity tool engineered to index, search, and answer questions about your specific offline documents, files, and transcripts.

Why OpenIntelligence is unique:
- 100% Offline: Indexing, OCR, transcription, and reasoning run entirely on Apple Silicon. Functions in Airplane Mode with no cloud dependencies, subscriptions, or data leaving your device.
- Citation-Backed Answers: Every response is generated from matching passages. Claims are verified against source texts; if a fact is missing, the engine states it cannot verify instead of hallucinating. Tapping a citation jumps to the exact page and highlight.
- Isolated Libraries: Keep projects, clients, or classes completely isolated in distinct local or iCloud-synced containers.

Engineering & Architecture (Docs Reference):
Built from the ground up to leverage the local hardware capabilities of Apple Silicon:
- Lexical & Semantic Hybrid Search: Combines local BM25 keyword matching with semantic vector databases. Vector operations utilize Apple's Accelerate framework (BNNS and vDSP_mmul matrix computations) directly on the Neural Engine and GPU.
- Local CoreML Inference: Runs on-device LLM reasoning using CoreML, optimizing memory and latency on Apple Silicon without cloud API endpoints.
- Verification Gate: A strict math-based validation layer inspects retrieved text fragments, strips out ungrounded assertions, and cancels speculative answers before displaying them.
- Hardware Telemetry HUD: Real-time system monitoring overlays SoC thermal outlines, active Neural Engine/GPU utilization, and memory layout configurations.
- Private Cloud Compute Compatibility: Securely integrates with Apple's Private Cloud Compute architecture for advanced context lengths exceeding on-device chip capacity (handled by the OS).
- Resilient iCloud Sync: Custom multi-device sync logic utilizing deletion tombstones, conflict resolution merging, and concurrent background file downloading using Swift TaskGroups.

How the workflow works:
1. Setup: No sign-up, logins, or cloud accounts.
2. Ingestion: Import files from iCloud/other apps or scan pages. OpenIntelligence extracts digital text, performs on-device OCR on scanned pages, transcribes audio/video locally, and builds vector indexes.
3. Querying: Query in natural language using local reasoning modes:
- Standard: Fast, direct lookups (names, dates, figures).
- Deep Think: Multi-step reasoning across multiple files or separate pages.
- Maximum: Exhaustive CPU and Neural Engine power for complex synthesis.

Supported Formats:
- Documents: PDF, DOCX, XLSX, PPTX, Markdown, CSV, RTF, TXT, HTML, JSON, XML, YAML, and code.
- Images: JPEG, PNG, HEIC, TIFF, GIF.
- Audio & Video: MP3, M4A, WAV, AIFF, MP4, MOV.

Performance & Limitations:
- Strengths: Finding facts, specifications, code references, and citations across manuals, legal documents, and research papers offline.
- Limitations: Parsing corrupted/legacy PDFs, poor handwriting in scans, iWork formats. Converting these to clean PDFs or TXT files first is recommended.

Subscription Tiers:
- Free: Evaluation mode with limited document ingestion.
- Pro: Unlocks unlimited documents, larger libraries, and deeper context-packing.
- Lifetime: One-time purchase to permanently unlock all features on all your devices.

Privacy:
No user tracking, no telemetry, and no remote server connections. Your data remains strictly yours.

What's New in the Latest Version 3.7.5

Last updated on May 29, 2026

Old Versions

Changes since 3.6:

Version 3.7.5:
- Hardened iCloud synchronization concurrency by offloading all synchronous database merging, file copying, and conflict resolutions off the Main Actor (UI Thread) to completely eliminate UI freezes and watchdog crashes.
- Accelerated multi-device data transfers using parallel Swift TaskGroups to download iCloud ubiquitous files concurrently rather than sequentially.
- Hardened download error recovery, ensuring isolated iCloud file download failures or timeouts do not stall or fail the entire library synchronization.

Version 3.7/3.7.1:
- Resolved a gesture conflict on iOS where long-pressing library pills in the horizontal scroll view failed to trigger the context menu, fully restoring library deletion on iPhones.
- Preserved full library identity in the Documents pill strip more reliably by preventing the document-count badge from collapsing names into ambiguous truncation.
- Fixed a synchronization issue in iCloud Sync where deleted libraries could be merged back and resurrected on other devices, and implemented deletion tombstones to automatically propagate deletions across all synced devices.
- Added automated local cleanup of vector databases, Spotlight search indexes, and UI presentation caches when a synced library is deleted on another device.
- Documents was tightened again with cleaner library pills, a less crowded header, smaller sync controls, and clearer organization/management surfaces.
- Shared-workspace and background-ingestion plumbing are more robust, with safer queue cleanup, cleaner reconciliation, and better handling for long-running work.
- Camera capture, OCR-heavy pages, and mixed digital/scanned documents import more reliably.
- Clean digital text is preserved more faithfully, while noisy scans and image-heavy pages still get the heavier recovery path when they need it.
- Retrieval is stronger across Standard, Deep Think, and Maximum, with better context packing, better use of surrounding document context, and less drift away from the source.
- Suggested questions and follow-ups are more grounded in the active library and less repetitive across refreshes.
- Chat handles direct attachments and captured content more smoothly, so it is easier to bring new material into the conversation flow.
- Answer inspection is much richer now, with clearer source review, timing, retrieval-quality, and evidence-detail surfaces when you want to see how a response was built.
- Technical answers and structured output render more cleanly, including stronger code block handling and clearer response detail views.
- Diagnostics and device-aware performance behavior are more stable on larger libraries and longer-running work, with deeper inspection tools behind the scenes for validation and monitoring.
- Added native App Store rating and review prompting triggers after successful query tasks.
- Resolved Mac Catalyst layout truncations, including the Sync Mode picker, action chips, and scrollable library selector pills.
- Enabled full iCloud ubiquity container access and network permissions for Mac Catalyst by packaging universal sandbox entitlements.
- Resolved Xcode build catalog warnings with a unified universal AppIcon configuration across iOS and macOS targets.
- Redesigned the Silicon hardware telemetry HUD to dynamically rotate motherboard borders (SoC and Taptic outlines) to match device layout rotation, added iPad layout coordinates, and cleanly hid visual outlines on Mac targets.
- Hardened suggested questions and 3D visualization keywords to aggressively filter out OCR junk, syntax noise, and generic templates.

This release is about making OpenIntelligence feel more complete from import to answer review: fewer weak spots between "I added a file" and "I trust this answer."
