NMR Data Process & Report Generator

1. OCR Quick Input: Use the left panel to upload or paste images (Ctrl+V). Click Start Recognition to automatically extract peak values from your spectrum. Adjust rotation if needed.

2. Smart Calculation: Choose a splitting pattern and input peaks. The system uses robust algorithms to calculate J-values, even for complex systems like ddd or tt.

3. Signal Management: Click Add to Table to save data. You can toggle the "test tube" icon to mark signals as Impurities (they will be visible in the table but excluded from the final report).

4. Professional Reporting: Select your solvent to get perfectly formatted strings with ¹H, J in italics, and correct subscripts for chemical formulas.

5. Persistent Storage: All your data is saved locally in your browser. Feel free to refresh the page!
