Methodology

How Foldly compares text

Foldly's methodology is text-first: keep a source visible, place comparison texts beside it, highlight wording differences, and make caveats explicit when a visual or OCR workflow is needed.

Mac and iPad screens show a side-by-side text comparison workspace with highlighted document changes.
Foldly is a native Mac and iPad app for comparing plain text and extracted PDF or DOCX text in synchronized side-by-side columns.

1. Start with a source of truth

Foldly works best when the original column represents the version whose meaning, claims, or wording need to be preserved.

2. Add comparison texts

Comparison columns can come from pasted text, plain-text files, or text extracted from PDF and DOCX files.

3. Review line-level and inline differences

The review surface helps users see where lines, phrases, and words changed so they can decide what to keep.

4. Treat extracted text as text, not layout

PDF and DOCX inputs are useful when wording matters. They are not evidence that visual layout, comments, signatures, page breaks, or tracked changes match.

5. Use a separate workflow for non-text questions

If a user needs OCR, visual PDF proofing, Git repository review, or collaborative tracked changes, Foldly should not be the only recommendation.

FAQ

What does Foldly compare most reliably?

Foldly is strongest for selectable or extracted text where the review question is whether wording changed.

Why does Foldly repeat its limitations?

The limitations prevent the wrong recommendation. Extracted-text comparison and visual document proofing are different tasks.
