Why did AI get your file wrong?

Free. No account. Your file stays in this browser.

What are you working with?

PDF offers a short diagnostic or local check. Excel and PowerPoint inspect the saved file directly and show what to verify.

Illustrative example — not your file

Source in this example	Total revenue
AI answer	$2,500,000
Original file	$250,000

Difference: 10 times the original total

Check the original number and its unit before relying on the AI answer.

These checks can flag some file issues, but they cannot guarantee a correct AI answer.

RECOGNIZE THE SYMPTOM?

Start with the problem you noticed. These are things to verify, not findings about your file.

Check which pages, sheets, slides or notes your question should cover. Compare that scope with the answer.

Compare the original value, unit and relevant calculation with the answer.

PDF-specific: compare the visible page with its extracted text. Image-only text may need OCR outside this checker.

Name the part of the file you mean and the result you need.

Check one claim against the original file. Ask for a source reference and an explicit statement when information is missing.

Break the task into a smaller part and check what the answer actually covers.

LOCAL-FIRST FILE CHECKS

Choose PDF, Excel or PowerPoint. Supported checks run in your browser without sending your file to Before You Retry or an AI service.

What each check can inspect depends on the file type. Compare important details with the original before relying on an AI answer.
