Revision note
This first release focuses on pasted or extracted text from drawings, schedules, and markups. It is a lightweight review surface for revision spotting, not a full CAD or PDF renderer.
Use this tool when
These are the practical situations where this workflow usually earns its keep.
You copied notes, schedules, or OCR text from two revisions and want a focused diff.
You need to detect numeric changes in sizes, ratings, flows, or dimensions quickly.
You want a simple summary before a coordination or review meeting.
Civil, mechanical, and electrical drawing review
Teams can compare extracted sheet notes and schedules without relying on a heavyweight CAD workflow for every small change review.
Procedure and permit revisions
Field operations and mining teams can use the same surface for text-first revision checks outside of formal drawing sets.
Facilities and hospital works
Extracted notes from maintenance or refurbishment documents can be reviewed locally before sign-off or discussion.
Common mistakes to avoid
These are the checks that usually keep the output useful instead of misleading.
Pasting whole documents with inconsistent formatting when a smaller extracted section would produce a clearer comparison.
Assuming the text diff replaces visual review of the original sheet or markup.
Ignoring context around a changed number when the unit or related note may also have changed.
Learn how to use this tool
Compare extracted drawing notes and schedules so revision changes are easier to spot and summarize.
