Set the version pair
Choose the approved before and after versions, dates, and owners for the comparison.
Document workflow / version comparison
A redline is only useful when you can see what actually changed.
We build private workflows that compare approved document versions, classify changes by section and type, and prepare a comparison report for the responsible reviewer.

Where version review loses time
The change is somewhere in the document.
The review work is finding the difference, understanding what it affects, and deciding whether it is acceptable.
Find every change
Identify inserted, deleted, moved, and reformatted content across sections and tables.
Prepare the review note
Summarize changes, affected sections, open questions, and the reviewer for the decision.
The version boundary
The system shows the difference. It does not approve the edit.
Keep versions attached
Every change is linked to the before and after file, page, and revision it came from.
Flag complex structure
Tables, images, formatting, and metadata changes are shown as review items rather than silently assumed.
The owner approves
Acceptance, rejection, and sign-off remain with the responsible professional and the business.
A first comparison workflow
Start with one document family and one review route.
Choose the document family
Pick contracts, policies, briefs, reports, or another set with recurring revisions.
Define the report
List the change types, sections, owners, and approval fields the reviewer needs.
Test with real revisions
Compare known redlines and check insertion, deletion, table, and formatting handling.
Deliver the comparison
Return the change map, section report, and open questions to the responsible reviewer.
A version comparison is useful when the change, the section, and the decision stay visible.
Why trust Pristine3D?
We build and operate production software.
Pristine3D Ltd builds and operates live digital products, and we run private AI workflows internally as part of our own operations. We scope around your real workflow: the documents you own, the questions your team asks, and the access boundary you approve. Based in Lagos, Nigeria, we work remotely with clients worldwide.
We already run live products
Based in Lagos, Nigeria, Pristine3D currently builds and operates smartcards.ng, venu.ng, photoshoot.ng, and ugc.ng in production.
We start with the actual workflow
One input, one output, one test set, and one person who owns the result. We scope a real workflow instead of a transformation programme.
The boundary stays visible
Cloud, model, storage, and messaging accounts stay in your name. The chosen data path, access rules, test record, documentation, and training are part of the agreed scope.

Straight answers
Common questions.
Does this approve a document version?
No. It prepares the comparison. Acceptance and sign-off remain with the responsible professional.
Can it compare scanned versions?
Yes, where OCR is scoped. The workflow flags uncertain text so the reviewer does not miss it.
How is this different from contract clause extraction?
That page maps clauses and obligations. This page is the revision workflow: comparing versions and preparing a change report.
Own your knowledge base
The model is not the product. The knowledge base is.
Documents, the retrieval index, access rules, and the workflows built around them are the asset, and they compound. We deploy so the knowledge base stays yours: on your accounts, in the environment you choose, under access rules your team defines. The model behind the answers is a connector, so the knowledge base moves with you, not with a vendor.
Your corpus, your index
The document store, metadata, and retrieval setup live on accounts you own. No vendor holds the corpus.
Models are swappable parts
Change the model provider, move regions, or go local without rebuilding the knowledge base or the workflow.
The knowledge base is the alpha
Every improvement to the corpus improves the answers, and the improvement stays with you, not with a vendor.
