Switching from Pedra: what to pick
- The frame changed. Roomagen kept it (drift 15.3, $0.40/photo) and Collov AI kept it (drift 11.0, $0.45/photo).
- You want fewer changes to the room. Collov AI (11.0), Roomagen (15.3), REimagineHome (16.2) and Apply Design (17.2) had clearly lower room 01 drift than Pedra (27.1) and kept the frame.
- The watermark gets in the way. Apply Design (1 free credit) and virtualstaging.ai (2 credits after email confirmation) gave us a free output with no watermark.
- It is too slow. REimagineHome (16 s) and Collov AI (18.6 s) vs about 35 s, frame kept.
- You do not want a subscription. Apply Design (Apply Coins, up to 9, $10 one-time (per coin)).
- A feature Pedra does not list. restyling a furnished room: Collov AI, Roomagen, REimagineHome and MeltFlex; day-to-dusk: Collov AI and Roomagen; a "virtually staged" disclaimer option: Collov AI and virtualstaging.ai; a stated commercial-use licence: Collov AI, virtualstaging.ai and MeltFlex.
$0.45 per photo on the cheapest option. The free output had a watermark (logo).
Room 01 drift 15.3, framing pass. Starter, $12/month.
Our room 01 download: no watermark, 1280x960, 38.7 s.
Why people look past Pedra
- It failed our framing check on room 01 (zoom 0.9871; 2.5% of the output is outside the original frame), so the delivered photo is not the exact view you uploaded.
- It ranks 6 of 7 comparable tools on room 01 architecture drift (27.1; lower is better).
- The free output we got had a watermark (badge).
- Editor note (lighting shadows, 3/5): Relit as a warm evening scene with lamps on, unlike the daylight original.
- Editor note (artifacts, 3/5): Adds fixtures that aren't in the flat: a pendant lamp over a new dining table and under-cabinet kitchen lights.
- Room 04: Pedra flagged this photo as a 360 image; we kept it flat. Alignment failed (14 inlier matches, 25 needed; a looser diagnostic also fails), so framing is unknown and drift (28.8) is unaligned. By eye the skylights and pillars sit where they are in the original.
Where Pedra holds up
- Editor note (fit to room, 5/5): Separate living and dining zones suit the open-plan room.
- It is among the cheaper options: $0.33 per photo (2 of 17).
Features listed on its pages: furniture removal (declutter), empty-room staging, sky replacement, virtual renovation (wall and floor recolor), 360 or video output and an API.
What our notes say about Pedra
- Room 01 (our test): 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.
- Room 02: Framing passes. Furnish / Modern / Whole photo.
- Room 03: Framing passes; drift 33.5 is the highest of Pedra's rooms, partly from new shelving and art on the walls.
- Room 04: Pedra flagged this photo as a 360 image; we kept it flat. Alignment failed (14 inlier matches, 25 needed; a looser diagnostic also fails), so framing is unknown and drift (28.8) is unaligned. By eye the skylights and pillars sit where they are in the original.
- Room 05: Framing passes. Unlike Collov, Pedra kept the steps up to the bay.
- Room 06: Framing passes.
- Pricing page: Annual: EUR 239/yr for 1,200 credits (about EUR 0.20/photo). The page's own table rounds 100 credits to EUR 0.28/credit.
- Cheapest plan: 1 credit per staged photo
- Redo: Thumbs-down a bad result and you may get the credit back

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.).
