-# AI Photo Edit
+# EditmaskwithAI
 
-AI Photo Edit is a self-hosted, web-based image editing tool that allows you to regenerate only a selected area of a photo using AI.
+A self-hosted, web-based AI photo editor. Paint over any object, describe what you want, and the AI replaces just that region — every pixel outside your selection stays untouched.
 
-## Core Concept
+## Quick Start
 
-**Have AI regenerate only a selected area of a photo.**
+### GPU machine (recommended — free inference, best quality)
 
-- Upload an image
-- Select a specific region (rectangle, ellipse, or freehand lasso)
-- Enter a prompt describing what to fix
-- Have AI regenerate only the selected region
-- Composite the regenerated region back into the original image
-- Preserve every pixel outside the selection
-- Maintain full edit history and reversibility
-
-**The system does not regenerate the entire image.**
-**The system does not alter any pixel outside the selected mask.**
-
-## Features
-
-### Selection Tools
-- **Rectangle**: Click and drag to select rectangular regions
-- **Ellipse**: Click and drag to select elliptical regions
-- **Lasso**: Draw freehand selections around irregular shapes
-
-### AI Modes
-- **Mode A (Default)**: Send only the selected patch
-  - Faster processing
-  - Lower cost
-  - Best for isolated fixes
-
-- **Mode B**: Send patch + full image reference
-  - Better style consistency
-  - More context-aware results
-  - Higher cost
-
-### Edge Blending
-- Adjustable feather slider (0-50 pixels)
-- Smooth blending at selection edges
-- Prevents harsh transitions
-
-### Edit History
-- Full history of all edits
-- Revert to any previous edit
-- Reset to original image
-- All edits are reversible

-## Installation
-
-### Prerequisites
-- Docker and Docker Compose
-- AI API key (OpenAI or Stability AI) for production use
-
-### Quick Start
-
-1. **Clone the repository**
 ```bash
-git clone <repository-url>
-cd EditmaskwithAI
+# Prerequisites: Docker + nvidia-container-toolkit
+# Install toolkit once (Ubuntu/Debian):
+curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey \
+  | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-ctk.gpg
+curl -s -L https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list \
+  | sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-ctk.gpg] https://#g' \
+  | sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list
+sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
+sudo nvidia-ctk runtime configure --runtime=docker
+sudo systemctl restart docker
+
+# Verify GPU passes through into Docker:
+docker run --rm --gpus all nvidia/cuda:12.1.0-base-ubuntu22.04 nvidia-smi
+
+# Clone and run:
+git clone https://github.com/outis1one/editmaskwithai
+cd editmaskwithai
+docker compose -f docker-compose.gpu.yml up --build
 ```
 
-2. **Configure environment variables**
+Open **http://localhost:3080**
+
+**First startup downloads the AI model for your GPU (5–20 GB, one time).** Models are cached in a Docker volume and survive rebuilds.
+
+---
+
+### Cloud API (no GPU required)
+
 ```bash
+git clone https://github.com/outis1one/editmaskwithai
+cd editmaskwithai
 cp .env.example .env
+# Edit .env: set AI_PROVIDER and your API key (see .env.example for options)
+docker compose up -d --build
 ```
 
-Edit `.env` and set your AI provider:
-```env
-# For OpenAI (DALL-E)
-AI_PROVIDER=openai
-OPENAI_API_KEY=your-openai-api-key-here
+Open **http://localhost:3080**
 
-# OR for Stability AI
-AI_PROVIDER=stability
-STABILITY_API_KEY=your-stability-api-key-here
+---
 
-# OR for testing (no AI, returns original)
-AI_PROVIDER=mock
-```
-
-3. **Start the application**
-```bash
-docker-compose up -d
-```
-
-4. **Access the application**
-- Frontend: http://localhost
-- Backend API: http://localhost:8000
-- API Documentation: http://localhost:8000/docs
-
-### Development Setup
-
-For development with hot-reload:
+### Updates (any machine)
 
 ```bash
-docker-compose -f docker-compose.dev.yml up
+git pull
+# GPU:
+docker compose -f docker-compose.gpu.yml up -d --build
+# or cloud:
+docker compose up -d --build
 ```
 
-- Frontend: http://localhost:5173 (Vite dev server)
-- Backend: http://localhost:8000 (auto-reload enabled)
+---
 
-## Usage
+## AI Providers
 
-### 1. Create a Project
-- Enter a project name
-- Upload your image (PNG, JPG, etc.)
-- Click "Create Project"
+| Provider | Setup | Cost | Quality |
+|---|---|---|---|
+| `local_gpu` | GPU machine + nvidia-container-toolkit | Free | Best (SDXL/FLUX auto-selected by VRAM) |
+| `openai` | `OPENAI_API_KEY=sk-...` | ~$0.02–0.04/image | DALL-E 3 |
+| `replicate` | `REPLICATE_API_KEY=r8_...` | ~$0.002–0.03/image | Multiple models |
+| `invokeai` | InvokeAI running on another machine | Self-hosted | FLUX/SDXL |
+| `comfyui` | ComfyUI running on another machine | Self-hosted | Any model |
 
-### 2. Select an Area
-- Choose a selection tool (Rectangle, Ellipse, or Lasso)
-- Draw your selection on the image
-- Adjust the selection if needed
+You can also mix: set a default provider in `.env` and override per-operation in the **Image → AI Provider Settings** dialog inside the app.
 
-### 3. Configure Edit
-- **AI Mode**: Choose Mode A (faster) or Mode B (better context)
-- **Feather**: Adjust edge blending (0-50 pixels)
-- **Prompt**: Describe what you want to change
+---
 
-Examples:
-- "Remove the person"
-- "Change sky to sunset"
-- "Fix the red eye"
-- "Add flowers"
+## GPU Tier Auto-Selection
 
-### 4. Process Edit
-- Click "Fix Selected Area"
-- Wait for AI processing (status shown in history)
-- View the result on the canvas
+The app detects your GPU at startup and picks the best model it can run:
 
-### 5. Manage History
-- View all edits in the history panel
-- Revert to any previous edit
-- Reset to original image anytime
+| Effective VRAM | Model selected | Notes |
+|---|---|---|
+| ≥ 24 GB | FLUX.1-schnell | Best quality, 4-step generation |
+| 12–24 GB | SDXL | Excellent quality |
+| 8–12 GB | SDXL + xformers | Good quality |
+| 6–8 GB | SDXL + attention slicing | Good quality, slightly slower |
+| 4–6 GB | SDXL + CPU offload | Good quality, slower (GTX 1060 6GB range) |
+| 2–4 GB | SD 1.5 | Fast, lower detail |
+| < 2 GB | SD 1.5 + CPU offload | Very slow — consider a cloud provider |
 
-## API Documentation
+Override the auto-selected model with `HF_MODEL_TXT2IMG`, `HF_MODEL_INPAINT` in `.env`.
 
-### Projects
+---
 
-**Create Project**
-```
-POST /projects/
-Body: { "name": "My Project" }
+## What it can do
+
+### Selection
+- **Smart Select (SAM brush)** — paint over an object, AI detects its exact boundaries
+- **Smart Select (click)** — click any object, SAM selects it
+- **Rectangle / Ellipse / Lasso** — classic selection tools
+
+### After selecting
+- **AI Edit** — describe what to change ("add a scar", "make it look aged")
+- **Make less symmetrical** — AI adds natural organic variation
+- **Replace with clipboard** — paste any image into the selection shape
+- **Scale by %** — make the selected object bigger/smaller, AI fills the gap
+- **Copy / Cut to layer** — non-destructive layer workflow
+- **Erase** — remove the selected region with AI fill
+
+### Image tools
+- **Text → Image** — generate from a text description (GPU or cloud)
+- **Upscale** — Real-ESRGAN AI upscaling (genuinely adds detail, not just resize)
+- **Prepare for Print** — one-click: AI upscale to target DPI + fit to frame
+- **Fit to Frame** — resize/crop/AI-extend to standard print sizes
+- **Expand Canvas (Outpaint)** — AI extends the image in any direction
+- **Remove Background** — one-click background removal
+
+### Print presets
+Frame sizes: 4×6, 5×7, 8×10, 11×14, 16×20, 18×24, 20×24, 24×36 (portrait + landscape)  
+DPI options: 72, 150, 200, 300 — 200 DPI is fine for 18×24" and larger (viewed from distance)
+
+---
+
+## Progress bars
+
+All AI operations show a real-time progress overlay. For local GPU inference, the bar advances step-by-step as the model denoises (e.g. "Step 14 / 30"). For cloud providers and upscale operations, it animates to indicate activity.

+## Troubleshooting
+
+**GPU not detected in Docker**
+```bash
+# Check toolkit is installed and Docker restarted:
+docker run --rm --gpus all nvidia/cuda:12.1.0-base-ubuntu22.04 nvidia-smi
+# If that fails, re-run: sudo nvidia-ctk runtime configure --runtime=docker && sudo systemctl restart docker
+```
+
+**Model download stalls or fails**
+```bash
+# Check logs for HuggingFace errors:
+docker compose -f docker-compose.gpu.yml logs -f | grep -E "local_gpu|Error|Failed"
+# If a private/gated model: add HF_TOKEN=hf_... to .env
+```
+
+**Out of VRAM during generation**
+- Reduce `LOCAL_GPU_MAX_PIPELINES=1` in `.env` (default 2)
+- Or override to a smaller model: `HF_MODEL_TXT2IMG=runwayml/stable-diffusion-v1-5`
+
+**Settings saved locally only**
+- The in-app AI Provider Settings dialog saves to localStorage for the session
+- To make settings permanent: edit `.env` and rebuild
+
+**Check API docs**
+```
+http://localhost:3080/api/docs
