Notes from the demo run

AI-generated

We signed up for Meshdiff, created two review projects, took the guided tour on your Sample Project and ran the v1 to v2 bracket diff end to end. The compare screen is the strongest thing you've built: two synced viewports on top, the combined voxel overlay underneath in green/red, and the Geometric Delta panel reading +1640 mm3, +42.9% volume, Size delta Y 4.0 mm — all on one screen with no scrolling. A hardware lead would understand what changed in about three seconds.

Highlights

The compare view answers the question in one screen
Added voxels +6,264, removed -1,218, volume delta +42.9%, tolerance 0.15 mm as tiles under the 3D view. You didn't make anyone dig for the number that matters.
Sample Project is seeded before the first click
A brand-new account already has bracket-v1.stl and bracket-v2.stl with a real diff between them. We reached your core value screen without uploading anything — that's the right call, and rarer than it should be.
Printability is stated as a rule, not a verdict
The project page spells out pass/warn/fail thresholds (thin walls <0.8mm, overhang >55deg / >60deg, unsupported area >20% / >30%) right next to the result. Engineers trust a tool more when the rubric is visible.
Version history reads like a changelog
'v1 to v2 — Volume increased by 1640 mm3 (42.9%). Bounding box changed by 0.0 x 4.0 x 0.0 mm. Printability status: pass.' written in prose next to +6,264 / -1,218. That entry is the product in one line.
Tour is skippable and doesn't block the workspace
'Show me around' is opt-in via a button rather than an unskippable modal on first load. Our walk reached the workspace without fighting an overlay.

Friction points

Unknown URLs render a developer error page, not a 404
Visiting /settings, /account, /teams or /billing shows 'Unexpected Application Error! 404 Not Found' followed by the React Router dev message '💿 Hey developer 👋 — You can provide a way better UX than this when your app throws errors'. Anyone landing on a stale or mistyped link sees your framework's internals. A catch-all route with a real 404 page is a one-file fix.
No settings or account route exists in the app shell
The sidebar offers Sign Out and a language picker but no way to reach account, billing or team settings — the only Upgrade path is the trial banner. Worth adding before the trials start expiring.

Couldn't reach

upload new version·Upload is a Pro feature and disabled on the sample project, so we exercised the existing v1/v2 diff instead.
