Short answer
On room 01 the three lowest drifts among tools that kept the frame were Collov AI (11.0), Roomagen (15.3) and REimagineHome (16.2). TINTY, Pedra and virtualstaging.ai failed framing. The automatic check has limits. Collov AI on room 05: Framing passes and drift is low (21.4) because the automatic check only looks at the top 65% of the frame. It misses the biggest change: the two steps up to the bay are gone. Misrepresentation risk.
| # | Tool | Room 01 drift / framing | Framing detail | Our note |
|---|---|---|---|---|
| 1 |  Collov AI | 11.0 Pass | zoom 1.0003, rotation -0.003°, 99.61% of frame visible, 0% invented | Lowest architecture drift on room 01 and kept the frame. Removed the chair that was already in the room (allowed: it is furniture). Output is slightly smaller than the original (1200x896 vs 1280x960). |
| 2 |  Roomagen | 15.3 Pass | zoom 1.0001, rotation 0°, 99.74% of frame visible, 0% invented | Kept the frame, low drift. The heavy tiled watermark makes the free output hard to use in a listing. Time is approximate (30–57 s observed). |
| 3 |  REimagineHome | 16.2 Pass | zoom 1.0028, rotation 0.048°, 99.81% of frame visible, 0.13% invented | Kept the camera frame. The tiled watermark on the free output adds some edges, which nudges drift up a little. A second run through Styldod (same engine) scored 14.4 in about 38 s; only the first output counts. |
| 4 |  Apply Design | 17.2 Pass | zoom 1, rotation -0.01°, 99.74% of frame visible, 0% invented | Kept the frame, no watermark, larger output. Slowest by far: about 585 s (almost 10 minutes) for one image, and the free tier is a single credit. |
| 5 |  TINTY | 18.1 Fail | zoom 1, rotation 0°, 89.06% of frame visible, 0% invented | Framing fails: the default crop frame returns a 3:2 image, so about 54 px are cut from the top and from the bottom (11% of the frame). Inside the visible area the architecture matches the original closely. Time is approximate (at most about 30 s). |
| 6 |  Pedra | 27.1 Fail | zoom 0.9871, rotation -0.48°, 99.88% of frame visible, 2.46% invented | Framing fails: zoomed out by about 1.3% and rotated about 0.5°, so roughly 2.5% of the image at the edges is newly drawn. After alignment the walls, column and doorway line up, but parts of the kitchen are redrawn and wall decor adds edges, so architecture drift stays high (27.1). Alignment explains about 10 of the 37.6 raw points. |
| 7 |  virtualstaging.ai | 28.2 Fail | zoom 0.9898, rotation -0.755°, 98.92% of frame visible, 2.94% invented | Highest architecture drift on room 01. The column is moved and the soffit is changed, which you can see in the comparison. It also zoomed out slightly and rotated about 0.8°, so framing fails. No watermark, same resolution as the original. |
| – |  MeltFlex | Unknown alignment failed; unaligned 48.5 not comparable | alignment failed | Free download paywalled (Subscribe €12/mo); saved on-page preview. Official alignment failed (20/25 inliers); drift 48.5 is unaligned fallback. Diagnostic ratio 0.8: framing FAIL (zoom 0.84, 29% invented), aligned drift 38.0 — not an official v0.2 score. |
Architecture drift runs from 0 to 100, lower is better (how much walls, windows and doors changed after aligning the output to the original). Differences of about 3 points or less are within measurement noise. Framing fails if the tool cropped, zoomed, shifted or rotated the photo beyond our thresholds.

Partial results: 1 of 10 rooms scored for most tools (Collov AI also has rooms 02-05, Pedra rooms 02-06 and Roomagen room 02. The leaderboard still compares room 01 only.).
