Mat3

The Mat3 guide

A clear review starts
with clear documents.

Bring the requirement, the exact product and its supporting evidence. Compare the materials, open the sources, draft supplier questions and save your decision and report.

The documents to bring.

Approved project requirements

Use a specification, BOQ description or finish schedule that states the material’s intended use and required properties. These might be paint finish, steel grade and diameter, a door’s size or documented performance. If a BOQ only names a material, add the missing requirements before approving your baseline.

Supplier documents

Upload the datasheet, relevant catalogue pages, packaging photos and test reports for the exact product offered. A catalogue can contain several sizes and finishes; choose the specific variant before comparison.

Supported files: PDF, JPEG, PNG, WebP, HEIC, XLSX and CSV. Files are limited to 25 MB, PDFs to 100 pages and spreadsheets to 10,000 populated rows. A submission can contain up to 20 files. One analysis uses up to 100 selected pages and 50 requirements.

Select only the pages or spreadsheet ranges you intend to review. A missing-evidence finding applies to the processed submission scope. Include the relevant supporting documents before deciding.

From documents to a decision.

  1. Create a project and choose the material category. Describe where it will be used and assign a reviewer.
  2. Upload your requirements, extract a draft and check every proposed value. Add missing requirements and approve the baseline.
  3. Upload the supplier’s files. Select the exact product and variant from the extracted candidates.
  4. Run the comparison and inspect each finding. Open the quoted page, image region or spreadsheet cell to check the source.
  5. Draft a supplier question from unresolved findings. Check the wording, save the draft, then copy or download it to share.
  6. Record a decision and download the PDF or CSV. Revised documents require a new submission revision and another comparison.

Try the same documents yourself.

Three completed tests use an IOM Nigeria BOQ, a CDK tile catalogue excerpt and an archived Dulux Trade product-guide excerpt. Each pack includes the inputs, reviewer-selected requirements, labelled expected findings and the actual saved reports.

Create your own test project, select the stated pages and approve the reference values after checking their sources. Choose the exact supplier variant, compare and inspect each finding. The pack README provides the full procedure.

A new upload creates new evidence locations. The reference sheet describes what to check; it does not automatically approve your requirements. Missing evidence applies to the submitted excerpt. The archived paint guide demonstrates a finish comparison and does not establish current availability.

What the checks mean.

Document OCR reads scanned pages and images. Gemini extracts requirements, supplier statements and product variants, using source block identifiers and quotations. The app validates citations before storing the output.

Rules compare dimensions after converting explicit metric units. For example, 60 × 60 cm and 600 × 600 mm are equivalent. Numeric performance checks require compatible units and the same stated test method. Gemini interprets requirements that need semantic comparison.

Only add the checks needed for the material. Paint can be reviewed for finish without tile dimensions. Steel can be checked for grade and diameter. Door and window dimensions keep their stated order; reversed width and height require clarification.

  • Matches: submitted evidence supports the approved requirement.
  • Conflicts: readable evidence contradicts the approved requirement.
  • Missing evidence: a required statement or document is absent from the fully processed submission scope.
  • Unclear: evidence is ambiguous, unreadable, contradictory or cannot be compared reliably.

These checks compare documented claims. Site suitability, physical quality and certificate authenticity require the reviewer’s judgement and separate verification.

Ask the supplier a clear question.

Choose “Draft supplier question” in a completed review. The draft uses the current unresolved findings, approved requirements, supplier values, reviewer notes and source locations.

Edit the subject and message before saving. Copy or download it to send through your email or messaging app. Saved drafts stay with the review; choose “Edit a copy” to prepare a revised question before recording the decision.

Keep the decision with the evidence.

The assigned reviewer can record Approved, Approved with conditions, Revise and resubmit or Rejected. Unconditional approval is blocked while required findings remain unresolved. Conditional approval requires a condition for each outstanding required finding.

A correction records the reviewer’s reason alongside the original machine finding. Approved baselines, reviewed supplier revisions, decisions and report snapshots are preserved. Changes create a new version; they cannot silently rewrite a previous approval.

Download the review and keep its history.

After recording a decision, choose “Generate PDF” or “Generate CSV.” The report contains the project and supplier, reviewed document versions, findings and source references, reviewer corrections, decision and conditions.

Return to the saved review to download the same report later. If the supplier changes the material or sends new documents, create a new submission revision and compare again. The earlier report continues to show the earlier decision.

Give each person the right access.

Owners manage the company and project assignments. Contributors upload documents and supplier proposals. Reviewers approve requirements; only the reviewer assigned to a particular review can record its decision. Viewers can read assigned projects and their reports.

Invitations are tied to a work email and expire after seven days. Cloud accounts require verified email. Uploaded files are private and are served only after checking company and project access.
