qbiq is an AI interior space planning platform that generates complete office design packages, including floor plans, 3D walkthroughs, and Revit-ready files in 24 hours or less. TestFit is a site feasibility platform that evaluates massing, zoning, and yield before a building is designed. They solve different problems at different stages of a project. TestFit ends at the shell; qbiq starts there.
What is the difference between qbiq and TestFit?
qbiq and TestFit are both AI tools used in commercial real estate, but they operate at entirely different stages of a project. qbiq handles interior space planning, turning an existing floor plate into a fully programmed office layout with workstations, conference rooms, and collaboration zones. TestFit handles site feasibility, evaluating whether a parcel of land can support a given density before design begins.
The practical difference between qbiq and TestFit is that if you have a vacant floor and need to show a tenant how their team fits, qbiq is the right tool. If you're deciding whether to buy a site and need to model unit mix and pro forma, that's TestFit. The two tools address different problems in the project lifecycle.
qbiq vs TestFit: feature-by-feature comparison
When should you choose qbiq?
qbiq is the right tool when your project involves an existing building and a tenant or client who needs to see how their team fits inside it. Choose qbiq if:
- You're a broker or landlord showing tenants how a space can work before the deal closes
- You need interior layouts with workstations, conference rooms, and breakout areas
- You want to go from a blank floor plate to a branded, 3D-rendered presentation package in one business day
- Your team has no in-house architect, but you need architect-quality deliverables at the RFP stage
- You're working in a commercial office, flex, or co-working
- Deal velocity is critical, and waiting a week for test fits is costing you leases
Brokers at JLL and Colliers use qbiq to respond to RFPs with complete design packages before competitors have an architect scheduled. By the time a traditional test fit arrives, the qbiq-equipped broker has already presented a photorealistic walkthrough. Book a demo at qbiq.ai →
When should you choose TestFit?
TestFit is the right tool for pre-development decisions. It is used before land is purchased, before a building is designed, and before a unit mix is finalized. Choose TestFit if:
- You're a developer evaluating whether a site can support the density you need
- Your project is multifamily, mixed-use, or involves structured parking
- You need to model unit mix, yield, zoning compliance, and ROI before buying land
- You're working pre-design: your output is a feasibility study, not a leasing presentation
- You need to test hundreds of massing configurations against a pro forma
- Your stakeholders care about doors-per-acre and IRR, not seat density and finish selection
TestFit is excellent at what it does. But once a site is acquired and a building exists, or you're working with existing commercial space, it's not the right tool for interior planning.
Can qbiq and TestFit be used together?
Yes. In development scenarios where a project includes both ground-up construction and commercial interior space, the two tools complement each other at different stages. A developer might use TestFit to evaluate a site, confirm unit mix and massing, and close on the land. Once the building is under contract or construction is complete, qbiq enters the picture for the commercial portions such as ground-floor retail, co-working amenity floors, corporate tenant suites, or speculative office space being marketed to tenants.
What makes qbiq different from other AI space planning tools?
qbiq delivers a complete downstream package. Where generic AI tools hand you a sketch to iterate on, qbiq produces a full design package including multiple layout variants, a photorealistic 3D walkthrough, an architectural program, a quantity takeoff, and an editable Revit model, all within 24 hours.
Three factors differentiate qbiq from other AI space planning tools:
Domain specificity. qbiq's AI is purpose-built for commercial office and trained on over 400 million square feet of real-world planning configurations. It understands efficiency ratios, workstation density, collaboration zone placement, and code-compliant circulation.
Output depth. The package includes everything needed to present to a tenant or advance to construction documents, including floor plans, 3D tour, quantity takeoff, and CAD/Revit export. No further tool is needed between qbiq's output and a client presentation.
Deal-stage focus. qbiq is designed for the moment between a vacant space and a signed lease. Brokers use it without an architect in the loop and still deliver credible planning packages at the RFP stage.

Gindi Studio processed significantly more projects with the same team by replacing manual test fit workflows with AI-generated layouts — the output-depth claim in practice. Read the Gindi Studio case study.
How to get started with qbiq
Upload a floor plate, set your program requirements, and receive a complete design package — floor plans, 3D tour, quantity takeoff, and Revit files — within 24 hours. No architect required.
Used by brokers at JLL, Colliers, and leading architecture firms worldwide.
Frequently Asked Questions
qbiq vs TestFit — which is better for commercial offices?
qbiq. TestFit operates at the site and building massing level and is not designed for interior office planning. qbiq was built specifically for commercial office, generating workstation layouts, meeting room configurations, 3D walkthroughs, and Revit files tailored to office use cases.
Are there alternatives to TestFit for interior space planning?
TestFit was never intended for interior space planning. If you've been using it for that purpose, qbiq is the purpose-built alternative. Other tools in the interior planning space include Archilogic and SpaceIQ, but qbiq's AI-generated complete design packages, including 3D tours and Revit-ready models delivered in 24 hours, represent the most advanced automation available for commercial office environments.
What are alternatives to qbiq for AI test fit generation?
Competitors include Archilogic and generic AI floor plan generators, but none match qbiq's combination of domain depth, output completeness, and turnaround speed for commercial office test fits. qbiq's planning engine is trained on over 700 million square feet of planning data, and its outputs include the full downstream package: 3D rendering, virtual tour, quantity takeoff, and exportable CAD/Revit files — delivered in a single workflow.
