Compare up to three actual products. Mandatory requirements come first. Blank scores remain unknown; these are your judgments, never measured material ratings.
Choose a JSON record downloaded from this workspace. It stays in your browser. Review the names below before replacing the current comparison; export any current work you want to keep.
1. Identify the products and screen requirements
Use the exact product, grade and profile from a quote or product document. A material family such as hardwood or composite is not a complete candidate. Leave requirements unresolved until you have their source basis.
2. Set the importance of each preference
0 excludes a preference from arithmetic. It never removes a mandatory requirement.
3. Read the possible score ranges
Bars show the possible preference score when missing ratings could be anywhere from 0 to 5. They are not statistical confidence intervals.
On a narrow screen, scroll the table sideways. Keyboard users can focus the table region and use the arrow keys.

What to resolve next
Requirements take priority over preference scores. For unknown scores, the point span shows how much that single missing rating contributes to the range at your current weights. It does not measure risk or prove that evidence is adequate.

? Exact product identity is missing
? Requirement and source basis are missing
? Mandatory requirement review is unresolved

Every row below changes only the selected weight. Other weights and your candidate ratings stay fixed. Overlapping ranges leave the preference order unresolved.

Machine-readable data
Work remains in this page until you export or choose an inquiry handoff. Reloading clears the comparison; download JSON to reopen it later. A handoff stores your review in this browser tab until removed; it does not send it.
Compare labeled samples, not promises.
Surface study / fictional samples
Illustrative surface study. These are fictional samples, not identified products or measured performance evidence. Detail views crop the same master image.
One scene. Three surfaces.
Compare surface character under consistent illustrative light. Choose a sample to separate a visible observation from an evidence requirement.
What remains unknown
None of these appearances establishes product identity, mechanical suitability, service life or approval for your project.
The next useful question
Obtain actual labeled samples and exact product documents, then record the requirement and its source in your comparison.
