Both tools staged the same empty room with default settings; only the first output counts. Verdict first, then every number we have.

Partial results. As of 21 October 2026 we have scored room 01 of 10 for 8 tools (tested 19 October 2026), plus a few extra rooms for some. The other 12 of the 20 tools we list are not tested yet. No final ranking. How we test
Fidelity is not comparable here: our alignment failed for MeltFlex, so its room 01 drift (48.5) is an unaligned fallback score and we do not compare it with Collov AI's aligned score. On published prices MeltFlex is cheaper per staged photo: $0.21 vs $0.45 on the cheapest paid option.
Built from the numbers below, not a paid placement. This is not a final ranking.

Same empty open-plan room, default settings, first output only. Each image shows the original next to the output; alignment failed for MeltFlex, so that image is not aligned.


Room 01: 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.
Pricing notes: Home-design tool, not real-estate specific. Counts are 'up to'. Page shows a countdown discount banner. 'Up to 100 AI renders' (490 credits); EUR 12/mo billed yearly.

Room 01: 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).
Editor notes: Living zone staged and kitchen untouched, which suits an open-plan room. Sofa, rug and chairs are sized right and leave the kitchen walkway clear. No melted or floating items; the large central collov.ai logo is the main blemish.
Pricing notes: Yearly billing: $0.32/photo (Standard) and $0.33 (Advanced). Credits reset monthly. 'High-resolution downloads' (no pixel size given); our free outputs were about 1.1 MP. $19/mo if billed yearly ($228).

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. Editor realism ratings are one person's 1-5 ratings, not blind. Details: methodology. 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.). Prices from vendors' public pages, checked 19 October 2026; EUR converted at the ECB rate (1.1253, 2026-10-16). Nobody paid for a placement, and affiliate links never change the order.
