Gunzino.me is my support hub for all 4 of my iOS Apps currently on the App Store + 1 prototype : OpenClinic is a provider workspace with SMART on FHIR and local clinical retrieval | OpenIntelligence is the local-first document intelligence stack | OpenResponses is the active Responses API playground | OpenCone is a cloud-hybrid OCR and vector search client | OpenAssistant is the legacy Assistants API build.

Products

Each page is written as a publisher surface for App Store review, user support, and technical evaluation: what the app does, which APIs it depends on, what stays local, and where the support and privacy routes live.

OpenClinic

OpenClinic

Clinical Workspace with Local Intelligence

Provider-facing charting workspace for iPhone, iPad, Mac Catalyst, and visionOS. Uses SwiftData, Apple Foundation Models, SMART on FHIR imports, and OpenIntelligence-derived retrieval components for grounded local clinical workflows.

OpenCone

OpenCone

Cloud-Hybrid OCR and Vector Search

SwiftUI client that extracts and OCRs files locally with PDFKit and Vision, then sends embeddings and search traffic to OpenAI and Pinecone serverless indexes. Useful for private corpora, but not a fully offline app.

OpenAssistant

OpenAssistant

Legacy Assistants API Client

Older native dashboard for OpenAI Assistants API threads, runs, files, and vector stores. Kept online for support and reference, but superseded by OpenResponses.
