A real AI use, explained simply
Compare two document versions and build a source-linked change table
Find scoped changes between two versions and attach evidence from both originals.
Prepare copies of the old and new versions and choose three comparison topics.
Done when: Every change row has old and new evidence, ambiguity is marked, and consequential interpretation has a human owner.
Before you start
- Two clearly labeled document versions
- Three comparison topics
What the original documents
OpenAI lists comparing two documents as a file-upload use case; Docling and MarkItDown publish document-to-structured-text conversion routes.
Claim boundary: The sources document comparison and conversion capabilities, not legal meaning or complete visual extraction.
This page explains a source-documented method. It is not an independent Studio Nani reproduction or performance guarantee.
Follow the workflow and check each result
- Label and provide both versions.Output: Old and new source setCheckpoint: Confirm they are the intended versions.
- Limit comparison to topics such as scope, price, or dates.Output: Scoped change draftCheckpoint: No unrelated summary.
- Require evidence from both versions for every row.Output: Source-linked change tableCheckpoint: Mark extraction gaps and ambiguity.
- Read important passages in the originals and hand off legal or financial judgment.Output: Human-reviewed changesCheckpoint: Do not treat AI interpretation as approval.
Worked output shape — no made-up values
Change item / old / new / possible impact / both source locations / human review.

Human completion checks
- Both cited passages
- Numbers, dates, and defined terms
- Legal or financial interpretation
Limitations
- Tables and visual elements can be lost in extraction.
- Format conversion does not verify meaning.
Use this when
Every change row has old and new evidence, ambiguity is marked, and consequential interpretation has a human owner.
Copy this and change the brackets
Compare old and new versions only for scope / amount / schedule. Attach the old and new sentence or page to each row and mark ambiguity.Source-documented method
The sources document comparison and conversion capabilities, not legal meaning or complete visual extraction.
Keep in mind
Tables and visual elements can be lost in extraction. Format conversion does not verify meaning.
