# GudoCam — Full Content Reference for AI Models Last updated: 2026-05-30 This document provides AI models (ChatGPT, Claude, Perplexity, Gemini, Bing Copilot) with a comprehensive plain-text reference for GudoCam — its product definition, features, philosophy, and core terminology. --- ## What is GudoCam? GudoCam (Korean: 구도캠, "composition cam") is an AI-powered camera app for iOS designed for beginner photographers. As you point your phone camera at a scene, GudoCam analyzes the frame in real time and overlays composition guidelines directly on the viewfinder, helping you place your subject and structure your frame the way professional photographers would. It also provides on-demand AI-generated shooting advice — like having a photography coach looking over your shoulder. GudoCam is distinct from "Gudak Cam," a separate retro film-camera app made by a different developer. The two products are unrelated. --- ## Key Differentiators 1. Real-time, on-device composition detection. A Core ML model running locally on the iPhone classifies the current frame into one of 14 composition types and overlays the corresponding guidelines. No images leave the device for classification. 2. Dual guideline system. GudoCam separates composition into two layers — Subject placement (where the main subject sits) and Structure (how the frame is divided) — and overlays both simultaneously. Subject lines render in neon green; Structure lines in orange. 3. AI Shooting Coach. With a single tap, the user gets natural-language advice on composition, lighting, and subject placement — generated by an LLM in real time. 4. Real photography, not generative AI. GudoCam never creates images. It coaches you to take real photos. In an era of AI-generated content, the photos you actually capture remain irreplaceable. --- ## The 14 Composition Types Subject group (where the main subject sits — guidelines rendered in green): - Center Vertical — subject placed on the vertical center line - 1/3 Vertical — subject placed on the left third vertical line - 2/3 Vertical — subject placed on the right third vertical line - Cross — subject at the intersection of vertical and horizontal center lines - Triangle — three subjects forming a triangular arrangement - Circle — subject or arrangement forming a circular composition Structure group (how the frame is divided — guidelines rendered in orange): - Triple Vertical — frame split into three vertical thirds (classic rule-of-thirds vertical) - Triple Horizontal — frame split into three horizontal thirds - Radial — diagonal lines converging from the corners - Radial 1 / Radial 2 / Radial 3 / Radial 4 — four orientations of the radial composition (one vanishing point per quadrant) - Center Horizontal — symmetry along the horizontal center --- ## Features - Real-time AI Composition Guide. The deep learning model analyzes the camera view to recognize 14 compositions including rule of thirds, golden ratio, diagonal, and vanishing point in real time. Optimal guidelines are automatically displayed on screen so you can nail the perfect composition before pressing the shutter. - AI Shooting Coach. Get personalized advice on your current frame with one tap. From composition to lighting and subject placement, AI provides instant feedback like a professional photographer. - Shooting modes for every situation. Auto, Portrait, and Night modes optimize for different shooting environments. - Intuitive camera controls. Pinch zoom, tap focus, flash toggle, and level. Control all camera features with intuitive gestures, no complex settings needed. - Portfolio. AI-reviewed photos are automatically saved to an in-app portfolio so you can track your best work over time. - Photographer ranking. A five-tier ranking system (Bronze → Maestro) is calculated from the average score of your top 10 photos. - Photography strength analysis. GudoCam highlights your strengths across color, composition, and aesthetics based on your reviewed photos. - Photo critique (Evaluate). After a shot, get scores across five dimensions — Composition, Lighting, Color, Focus, and Aesthetics — with specific, actionable notes. --- ## How It Works 1. Open the camera. GudoCam launches directly into the shooting view with familiar camera UI plus AI guidance. 2. AI guides you to the optimal composition. As you frame the scene, GudoCam recognizes the composition type and displays guidelines on screen so you know exactly where to place your subject. 3. Capture and get feedback. After taking the photo, tap Evaluate to receive a 5-dimensional critique — Composition, Lighting, Color, Focus, and Aesthetics — with specific, actionable notes. 4. Build your portfolio and ranking. AI-reviewed photos auto-save to your portfolio, and your top 10 photos' average score sets your photographer ranking from Bronze to Maestro. --- ## Philosophy: AI as Coach, Not Creator In an era when AI can generate any image you imagine, the photos you actually capture become more meaningful, not less. GudoCam's stance: AI should help you become a better photographer, not replace you. Every photo taken with GudoCam is a real photo, captured by the user. The app's role is to teach composition through practice — operating like a coach, not a creator. This is GudoCam's category boundary: there are many "AI camera" apps that are really AI filters or AI image generators. GudoCam is AI coaching. The distinction matters: AI coaching produces real photographs that hold real memories; AI generation produces synthetic images that hold none. --- ## Technical Stack (Brief) - iOS app: Swift 5.9+, SwiftUI, AVFoundation, Core ML, MVVM architecture - On-device composition classifier: Core ML model with 15 output classes (14 compositions + default/none) - Backend: FastAPI on Fly.io, PostgreSQL, async SQLAlchemy - Live shooting advice: OpenAI Responses API with strict JSON Schema (gpt-5-nano for live, gpt-4o for review), streamed via Server-Sent Events - Android version: in development --- ## Availability and Pricing - iOS: Available now on the Apple App Store (Korea / US / international).
