+
+### OCR Click-to-Copy (`clicktodo`)
+
+The `clicktodo` command provides an OCR-based workflow for extracting and copying text from anywhere on your screen:
+
+1. Captures a fullscreen screenshot
+2. Runs OCR to detect all text on screen (via persistent daemon for speed)
+3. Shows an interactive overlay with detected text regions highlighted
+4. Click any text region to copy it to clipboard
+5. Press `ESC` or right-click to cancel
+
+**Performance:** Uses RapidOCR + ONNXRuntime for 5-15x faster processing than traditional OCR engines. Typical latency: 300-600ms on a 2880x1800 display.
+
+**Setup:**
+
+1. Install OCR dependencies:
+   ```sh
+   pip install caelestia[ocr]
+   # Or manually: pip install rapidocr-onnxruntime onnxruntime PyQt6 numpy
+   ```
+
+2. Run the setup script to configure the OCR daemon:
+   ```sh
+   ./setup-ocr.sh
+   ```
+
+   This will:
+   - Install dependencies if missing
+   - Set up a systemd user service for the OCR daemon
+   - Create default configuration at `~/.config/caelestia/ocr.json`
+   - Start the daemon (models stay hot in memory for instant responses)
+
+**Requirements:**
+- Requires `grim` and `wl-clipboard` (already needed for other features)
+- Python 3.13+ with pip
+
+**Hyprland keybinding example:**
+
+Add to your `hyprland.conf`:
+```
+# Standard mode
+bind = SUPER, O, exec, caelestia clicktodo
+
+# Fast mode (more aggressive optimizations)
+bind = SUPER SHIFT, O, exec, caelestia clicktodo --fast
 ```
 
+**Usage:**
+```sh
+# Standard mode
+caelestia clicktodo
+
+# Fast mode (downscales more aggressively, limits max boxes)
+caelestia clicktodo --fast --live
+```
+
+**Configuration:**
+
+Edit `~/.config/caelestia/ocr.json` to customize:
+```json
+{
+  "provider": "cpu-ort",    // cpu-ort, gpu-rocm, npu-xdna (future)
+  "downscale": 0.6,         // Detection downscale factor (0.5-1.0)
+  "tiles": 1,               // Parallel tiles (future feature)
+  "max_boxes": 300,         // Maximum text boxes to detect
+  "use_gpu": false,         // Enable GPU (experimental on AMD)
+  "warm_start": true,       // Run warm-up on daemon start
+  "performance": {
+    "idle_threads": 1,      // Background thread budget when idle
+    "standard_threads": 4,  // Default thread budget during normal OCR
+    "fast_threads": 0,      // 0 = auto, otherwise specific thread count
+    "idle_cores": 1,        // CPU cores kept active when idle
+    "standard_cores": 0,    // 0 = auto mid-range core count
+    "fast_cores": 0         // 0 = all available cores during bursts
+  }
+}
+```
+
+Set any value to `0` (or omit the key) to allow the daemon to auto-detect from the host CPU. Leave the entire `performance` block out to use adaptive defaults.
+
+**Daemon Management:**
+```sh
+# Check status
+systemctl --user status caelestia-ocrd
+
+# Restart daemon
+systemctl --user restart caelestia-ocrd
+
+# Stop daemon
+systemctl --user stop caelestia-ocrd
+
+# View logs
+journalctl --user -u caelestia-ocrd -f
+```
+
+**Future Optimizations:**
+- NPU acceleration via AMD XDNA (when ONNX Runtime EP is stable on Linux)
+- GPU acceleration via ROCm (when Radeon 890M iGPU is officially supported)
+- Parallel tile processing for ultra-high-resolution displays
+
 ## Configuring
 
 All configuration options are in `~/.config/caelestia/cli.json`.
