+
+# CalcTrainer Annotator 📝
+
+**Annotation tool for validating OCR predictions on handwritten math answers from [CalcTrainer](https://huggingface.co/spaces/hoololi/CalcTrainer)**
+
+## How to Use
+
+1. **Review** the math problem and handwritten answer
+2. **Validate or correct** the OCR suggestion:
+   - **✅ Correct** → Validates and moves to next
+   - **❌ Incorrect** → Type correct number and validate
+3. **Export** annotations anytime to save progress
+
+## Features
+
+- **Smart filtering**: Only shows unannotated entries
+- **OCR suggestions**: Pre-filled predictions with error warnings
+- **Incremental export**: Safely add annotations without data loss
+- **Progress tracking**: Real-time statistics
+
+## Data Flow
+
+```
+CalcTrainer → Raw Dataset → Manual Annotation → Validated Dataset
+```
+
+## Output
+
+Creates `hoololi/CalcTrainer_dataset_annotated` with human-validated labels for OCR model fine-tuning.
+
+**Private Space** - Controlled access for annotation quality.
