Planner 5D Alternative for Architects (2026)
6 min read
Planner 5D has been a go-to for DIY room planning for years, and the reason is simple: it's free to start, runs in a browser or on a phone, and lets anyone drag walls and furniture into place and see the result in 3D within minutes. Homeowners use it to plan a renovation, students use it to learn layout basics, and its AR mode lets you point a phone at an empty room and preview furniture in place. That's a genuinely useful toolset for planning a space from nothing. The honest question is what happens when the space already exists — a real room, a hand sketch, a CAD export — and the job is rendering it, not rebuilding it.
What Planner 5D gets right
- Free and instantly accessible. No install required — open a browser tab or the mobile app and start placing walls and objects immediately.
- AR preview. Point a phone camera at a real room and see placed furniture overlaid in the actual space, which is a genuinely handy sanity check before a purchase.
- A large object and template catalog. Thousands of furniture and decor items, plus ready-made room templates for common layouts.
- Both 2D and 3D views side by side. Switching between a floor-plan view and a 3D render of the same layout while editing is smooth and beginner-friendly.
Where it shows the ceiling
- Everything is built by hand inside the app first. There's no path from a real room photo or a hand-drawn elevation straight to a finished render — the space gets modeled from scratch, wall by wall.
- No CAD or BIM import. A SketchUp, Revit or 3ds Max model doesn't carry over; the room has to be rebuilt in Planner 5D's own editor.
- Interior and floor-plan focused. It's built for furnishing and laying out rooms, not for rendering an exterior facade, a masterplan, or a site photo.
- No masked edits or video. You can move or swap objects you placed, but there's no way to change just one material on an existing photo, and no walkthrough video export.
Honest comparison
| Planner 5D | Archome | |
| Workflow | Build the room inside the app, then furnish it | Upload a photo, sketch or CAD view, render it directly |
| Input | Modeled from scratch in-editor | Photo, hand sketch, floor plan, SketchUp/3ds Max viewport |
| AR preview | Yes, via mobile app | Not the focus — output is render-ready stills and video |
| Exterior / facade | Not the focus | Dedicated Exterior AI tool |
| Video / 3D output | Static 3D views and panoramas | Cinematic video and 3D export via to-3D |
| CAD/plugin path | Own modelling environment only | Free SketchUp and 3ds Max plugins |
| Free tier | Free with limits on premium content | Free — 100 credits to start, no card |
Who should pick which
If the job is planning a room layout from a blank slate — deciding where a sofa or a kitchen island goes, previewing it in AR before committing, and doing it at zero cost — Planner 5D is a solid, purpose-built tool for exactly that. Its catalog and template library make early-stage layout genuinely fast, and the AR check is a real advantage for a homeowner deciding on furniture.
If the space or design already exists — a real room photo, a hand sketch, a plan drawn in Floor Plan AI, or a viewport exported from CAD — the job is preserving that geometry, not rebuilding it as objects one at a time. Interior AI keeps the walls, windows and proportions from your upload and changes only what you describe, and the same account covers sketch-to-render, exterior, floor plans, video and a 4K enhancer — so one upload goes from concept to finished walkthrough without remodelling the space by hand.
A five-minute test
Take a phone photo of a real room, or a hand sketch of a layout you're already committed to, and try to get a finished, photorealistic render from it in each tool without rebuilding the space as objects first. That single step — remodel required, or not — is usually the whole decision. The 2026 AI interior design tool roundup covers where the rest of the category lands if Planner 5D isn't the only alternative on the list.
Verdict
Planner 5D is a genuinely useful, free tool for the job it was built for — planning a room from an empty floor plan, with AR to sanity-check the result. Archome assumes the opposite starting point: the room, sketch or model already exists, and the fastest path to a usable image starts from what you already have. Upload a room photo and see it rendered without modelling anything — first renders are free.
