## OpenCone Description
Transform your iPhone and iPad into a self-contained RAG powerhouse. Import PDFs, Word docs, code, images, and text into a secure sandbox - extraction, embedding, and semantic search happen with zero lock-in. Point the app at your OpenAI and Pinecone credentials for a private knowledge base that streams grounded, citation-backed answers in real time.

COMPLETE DOCUMENT PIPELINE
• Multi-format extraction: PDF, DOCX, TXT, HTML, Markdown, JSON, CSV, and code
• Apple Vision OCR for on-device image text recognition
• MIME-aware chunking with configurable size and overlap
• Security-scoped bookmarks preserve file access across launches
• Deduplication by path, size, and timestamp fingerprinting
• Live progress tracking with structured logs for every phase

SEMANTIC SEARCH WITH STREAMING
• One-tap queries embed prompts and run similarity search against Pinecone
• Server-Sent Events deliver incremental answer deltas—no blocking spinners
• Citations reference exact chunks with document names and source metadata
• Metadata filters scope searches to specific documents or custom tags
• Conversation memory keeps recent turns in context for coherent follow-ups

GPT-5 REASONING MODEL SUPPORT
• Choose between standard models (GPT-4o, GPT-4o mini) or GPT-5
• Dynamic controls: reasoning effort for GPT-5, temperature/top-p for others
• Unified Responses API with conditional parameterization

RESILIENCE & OBSERVABILITY
• Pinecone health checks surface outages with dismissible banners
• Circuit breaker prevents hammering unhealthy hosts
• Watchdog timers catch stalled streams and trigger fallbacks
• Per-search trace IDs and granular log levels make every stage inspectable
• Error banners auto-dismiss after 8 seconds with user-friendly summaries

SETTINGS & PRIVACY
• Credentials in Keychain via SecureSettingsStore
• Release guardrails prevent accidental key leaks
• Model selection, chunk parameters, top-k defaults, metadata presets persist
• Reset control wipes credentials and history without reinstalling
• Guided onboarding validates API keys before unlocking main interface

POLISHED SWIFTUI EXPERIENCE
• Theme manager with alternate icons and dynamic color schemes
• Reactive MVVM-S architecture decouples views from business logic
• Async/await throughout keeps UI responsive during heavy operations
• Design system components ensure consistency across all tabs

Whether building surgical references, legal research corpora, or personal knowledge vaults, OpenCone delivers production-grade RAG without vendor dashboards or billing surprises.
