How to Use

A guide to screenshot calculations

Choose a clear image

Upload, drag, or paste a PNG, JPG, or WEBP image up to 10 MB. Crop unrelated content and make sure digits and operators are readable.

Analyze and review

Select Analyze screenshot. OCR runs in your browser; the first use loads its library from jsDelivr. After analysis, expand “Review text read from image” and compare it with your screenshot. Correct the expression in the manual calculator when needed.

Check the calculation

Detected arithmetic is evaluated locally. Inspect the detected values and displayed total. The tool does not fully understand financial documents or arbitrary algebra, so check that the proposed expression matches the question you intended to solve.

Manual calculations

Enter numbers with +, -, *, /, and parentheses. Press Calculate or Enter. Unsupported input produces an error message.
