Known limits

What Plyvel does not do today, stated plainly. Passing tests do not make any of this go away.

What is not measured

Openings, thin features, signage text and visual artefacts have no instrument in this release. They are handed to the reviewer and appear as not measurable, never as passed.
The building outline is measured only when you supply outline masks, and Plyvel cannot tell whether a mask is accurate.
Some thresholds are engineering hypotheses. Each is marked “not validated” where it is shown, and the receipt records it.
The colour-difference map shows where pixels changed. It is not a geometry heatmap.

Product

One person, one computer: no accounts, no sharing and no history beyond the project list.
Jobs run one at a time, cannot be cancelled, show a stage rather than a percentage, and are not resumed after a restart.
One observation per review group, not per item.
Model rendering needs Blender on your computer, replaces the scene’s lights with a preset, frames the camera automatically and greys out missing materials.
Observations are kept in the browser session only; a browser restart during a long review loses the text. Viewer zoom, mode and position reset on navigation.
Exported file names still carry the product’s old working name.

This site

English only; the Arabic version is a translation still to come.
Tested in Chromium, Firefox and WebKit (Safari’s engine) at desktop size, and at 390 px with touch by emulation; no physical phone or tablet, and not in Safari itself.
Nothing is charged: there are no plans and no accounts.
The included example is a procedural pavilion. It is not a client project, and no better imagery exists on this site yet.
