Why compare versions
Instructional design is collaborative work. The script goes back and forth with the subject-matter expert (SME), the client, the review. Without a fast way to see what changed, review becomes a treasure hunt — and changes slip by unnoticed.
This tool compares line by line and highlights what came in and what went out, plus how much the text grew or shrank. Useful to approve a review round, check whether a requested cut was made, or document a content's history.
Everything runs in your browser — the texts never leave your computer.
