Foldly
Text comparison
A review of wording-level differences between two or more text versions.
Definitions
Text comparison glossary
This glossary defines the terms Foldly uses for text-level document comparison, extracted-text review, and draft revision workflows.
Why these definitions matter
Many document comparison terms sound similar but imply different tools. Foldly is explicit about text comparison so users do not mistake it for visual proofing, OCR, or tracked-changes collaboration.
Definitions
Side-by-side diff
A comparison layout that keeps versions in separate columns so differences can be read in context.
Original column
The baseline or source text column that can become the final edited version in Foldly.
Comparison column
A second or later column used to show another draft, export, prompt output, or extracted document text beside the original.
Extracted text
Text pulled from a PDF or DOCX file for wording-level comparison.
PDF text extraction
The process of reading selectable PDF text so it can be compared as text. It is not the same as visual PDF comparison.
DOCX text extraction
The process of reading document text from a DOCX file for comparison outside the original Word layout.
Visual PDF comparison
A layout-level comparison of rendered PDF pages, typography, signatures, page breaks, and visual placement. Foldly does not do this.
OCR
Optical character recognition, a process that converts image-based text into selectable text. Foldly does not OCR image-only PDFs.
Line-level change
A difference shown at the line or paragraph level.
Inline difference
A more specific difference inside a line, such as changed words or phrases.
Source of truth
The approved baseline text that other drafts, exports, or returned files are checked against.
Final-send review
A last text-level check before sending, publishing, or sharing a document.
Prompt-output review
A workflow for comparing AI or prompt-generated text outputs before selecting or editing the final version.
