Spacely AI Interior Design vs Archmaster: Compared (2026)

Spacely AI has quietly become one of the more credible tools in the professional AI rendering space — over 580,000 users, including design teams at firms like Gensler, and a feature set built around how architects and interior designers actually work: sketches, SketchUp exports, and 3ds Max files, not just photos. In September 2025 the platform moved from unlimited renders to a credit system, which changes the math for anyone comparing it against a simpler, photo-first tool like Archmaster.

Key Takeaways

• Spacely AI's free tier gives 40 trial credits; paid plans start at $20/month (annual billing) for 500 credits (Toolchase, 2026).
• Spacely AI's SketchUp plugin and 3ds Max import are real differentiators for professionals working from CAD files, not photos.
• Archmaster covers the same interior/exterior ground from a single uploaded photo, with an ongoing free tier and no credit-purchase decision required to start.

RoomGPT-style tools and Spacely AI solve different problems even though both produce photorealistic renders: one is built for a homeowner with a phone photo, the other for a designer with a 3D model. This comparison covers rendering scope, input formats, editing control, pricing, and who each tool actually fits, based on verified 2026 pricing and feature documentation.

Quick Comparison

Is Spacely AI Interior Design Built for Professionals or Homeowners?

Spacely AI wins decisively for anyone working from a 3D model rather than a photo. Its native SketchUp plugin and 3ds Max export support let architects and interior designers turn an existing model directly into a photorealistic render, preserving the exact geometry they already built rather than reconstructing it from a photo.

Archmaster's workflow starts from a photo of the actual space, which is the right input for a homeowner or renovator who doesn't have (and doesn't need) a CAD file. For a design professional already working in SketchUp, that's a step backward, not forward.

Verdict: Spacely AI wins for CAD-based professional workflows; Archmaster wins when a photo is the only input you have.

---

Which Tool Covers More Project Types?

Archmaster wins on breadth. Spacely AI's 12+ tools — Realistic Render, Auto Furnish, Style Transfer, and Point-and-Edit region refinement among them — cover interior redesign and exterior/facade work well, but the platform doesn't extend into landscape design or floor plan generation.

Archmaster covers exterior house design, yard and landscape redesign, and can generate an AI floor plan from a photo or sketch, in addition to interior work — a wider slice of a full renovation project in one tool.

Verdict: Archmaster wins for any project that includes landscaping or a floor plan alongside the render.

---

Which Gives You More Editing Control?

Roughly comparable, with different strengths. Spacely AI's Point-and-Edit feature lets you refine a specific region of a render without regenerating the whole image, similar in spirit to Archmaster's targeted-edit workflow. Spacely also supports reference-image style transfer, letting you feed in a photo of a look you want replicated.

Archmaster supports targeted edits to a specific render element plus generating multiple style variations from the same source photo to compare side by side.

Verdict: Tied — both offer targeted, non-destructive editing rather than forcing a full regenerate for every change.

Pricing Comparison

Spacely AI's free plan includes 40 trial credits with watermark-free output and a commercial license. Paid tiers, billed annually, start at $20/month for Personal (500 credits/month, roughly 250 renders since most renders cost 2-8 credits), rising to $40/month for Studio (1,500 credits, 2 seats) and $80/month for Agency (3,500 credits, up to 5 seats plus API access). Credit-only top-ups are available separately, and monthly (non-annual) billing runs higher than the rates above.

Archmaster's free tier is ongoing rather than credit-limited to a one-time trial — a generation ceiling per period rather than a stock of credits that depletes and must be topped up or upgraded away from.

The practical difference: Spacely AI's pricing is built for someone budgeting renders across a project or a team, with per-render credit costs to track. Archmaster's model suits someone who wants to test a few directions in a session without first deciding how many credits that will consume.

Value verdict: Spacely AI's credit system makes sense for a studio managing render volume across clients; Archmaster's simpler ongoing free tier fits a single homeowner-scale project better.

Who Should Choose What

A design professional working from SketchUp or 3ds Max files: Choose Spacely AI — its native plugin and CAD import are real, documented advantages Archmaster doesn't have.

A studio or agency managing render volume across multiple clients: Choose Spacely AI's team-seat plans and credit budgeting.

A homeowner or renovator working from a phone photo, not a 3D model: Choose Archmaster — no CAD file required, and the workflow is built around a photo from the start.

Someone whose project includes a yard, landscape, or floor plan alongside the interior: Choose Archmaster — Spacely AI doesn't cover landscape design or floor plan generation.

Frequently Asked Questions

Is Spacely AI better than Archmaster?

Spacely AI is built for design professionals — it has a SketchUp plugin, 3ds Max import, and team seats that Archmaster doesn't offer. For a single homeowner working from photos rather than CAD files, Archmaster's simpler, free-to-start workflow covers the same interior and exterior ground without a credit-purchase decision upfront.

How much does Spacely AI cost?

Spacely AI's free plan includes 40 trial credits. Paid plans start at $20/month billed annually for the Personal tier (500 credits/month), rising to $40/month for Studio (1,500 credits) and $80/month for Agency (3,500 credits, up to 5 seats). Most renders cost 2-8 credits each.

Does Spacely AI work from a SketchUp or 3ds Max file?

Yes — this is one of Spacely AI's core differentiators. Its native SketchUp plugin and 3ds Max export support let architects and designers turn an existing 3D model into a photorealistic render directly, which Archmaster's photo-first workflow doesn't offer.

Can Spacely AI or Archmaster generate exterior renders?

Both can. Spacely AI supports exterior and facade redesign alongside its interior tools, and Archmaster covers exterior house design, landscaping, and floor plans in addition to interiors.

Verdict

These tools serve different starting points more than they compete head-on: Spacely AI is the stronger pick if you're already working from a 3D model and need professional-grade credit budgeting across a team. Archmaster is the simpler path if a phone photo is your only input and your project might span an interior, exterior, and yard.
