AI Software for Architects 2026: Forma, Hypar, TestFit, Veras & LookX Compared

"AI software for architects" now covers two completely different jobs, and most comparison lists blur them together. Some of these tools help you decide what to build — massing, feasibility, unit yield, site analysis. Others help you show what you designed — photorealistic renders from your model or a sketch. Buying the wrong category is the most expensive mistake here, because a feasibility engine will never give you a client-ready render, and a render tool will never tell you whether the massing pencils out.

This guide compares the five names architects actually shortlist in 2026 — Autodesk Forma (the former Spacemaker), Hypar, TestFit, Veras, and LookX — from an architecture and archviz practitioner's point of view: what each one is really for, what it costs, what it plugs into, and where it sits in a real project.

Quick verdict

• Autodesk Forma (ex-Spacemaker) — the strongest choice for early-stage site planning and environmental analysis (sun, wind, noise, embodied carbon). Best if you already live in the Autodesk/AEC Collection ecosystem. Not a rendering tool.
• Hypar — cloud generative space planning: floor plans, structural grids, and furniture layouts driven by rules. Best for repetitive building logic and teams that want automation without scripting.
• TestFit — the real-estate feasibility workhorse: parking, yield, unit mix, and cost in seconds. Built for developers and the architects who serve them, not for design imagery.
• Veras — AI rendering that lives inside your modeling app (Revit, SketchUp, Rhino, Archicad and more). Best when geometry fidelity matters and you want to stay in your BIM/CAD tool.
• LookX — affordable web-based AI rendering with video and custom style training. Best for fast, cheap concept visuals and mood exploration.

If your question is really "how do I turn these concepts into client-ready visuals," that's a separate rendering-and-post-production step — covered near the end, where dedicated AI rendering tools like Visiomake come in.

How to read this comparison: two categories, not one race

Before the individual reviews, fix the mental model. Forma, Hypar, and TestFit are decision tools. They answer questions like "how many units fit," "does the daylight work," "how much parking do we need," "what does the massing do to wind comfort." You use them at the start of a project, and their output is data and geometry, not imagery.

Veras and LookX are visualization tools. They answer "what will this look like" and turn geometry or a sketch into a render. You use them from concept through client presentation. They will not tell you whether your scheme is buildable or profitable.

Almost every real office needs one tool from each category — plus a way to take the resulting render across the finish line for clients. Keep that in mind as you read; the visualization pipeline is where the categories eventually meet.

Autodesk Forma (formerly Spacemaker)

Autodesk acquired Spacemaker in 2020 and rebuilt it as Forma; the early-stage product is now officially Forma Site Design. It is a cloud platform for the conceptual phase: you sketch massing directly in the browser and Forma runs real-time analysis on sun and daylight, wind comfort, noise, and embodied carbon as you push volumes around. That instant feedback loop is what made Spacemaker famous, and it is still Forma's core strength.

What it costs

Standalone Forma Site Design runs roughly $185/month (about $1,500/year). More commonly, architects get it bundled in the AEC Collection (~$430/month or ~$3,430/year), which also includes Revit, AutoCAD and Civil 3D — so if your office already pays for the Collection, Forma is effectively free to try.

Where it fits

Forma is for feasibility and site strategy, not imagery. It connects to Revit, Rhino and Dynamo and reads IFC/OBJ, so massing decisions carry forward into BIM. The catch: it is deliberately a planning tool. When you need a render for a client, you leave Forma and go to a visualization tool. Best for mid-to-large practices already invested in Autodesk.

Hypar

Hypar is a cloud generative-design platform that automates repetitive building logic. Its model is "functions": reusable rules for things like structural grids, core placement, daylight, facade layout, and furniture, which you chain into a workflow that generates an entire building system from a spatial program. With Hypar 2.0 the company pivoted hard toward space planning, turning what used to be a scripter's playground into something closer to a cloud layout tool a generalist can use.

What it costs

Hypar offers a free tier to explore functions and layouts; serious/team use is enterprise pricing on request. That opacity is the main friction for small offices trying to budget.

Where it fits

Reach for Hypar when your work has repeatable logic — offices, labs, multifamily, anything where the same rules regenerate as inputs change — and you want editable masses, grids and layouts without writing Grasshopper from scratch. It exports to Revit and connects to Rhino/Grasshopper. Like Forma, it produces design intelligence, not renders.

TestFit

TestFit is the real-estate feasibility platform in this list. Its configurators generate rapid site plans and instantly count parking stalls, unit mix, yield, and yield-on-cost from your parametric inputs — the tedious math that used to eat days of a deal. It is aimed squarely at developers and the architects who do feasibility work for them, where speed to a defensible number wins the deal.

What it costs

TestFit is tiered: an Urban Planner plan around $100/month (billed annually), a Data Maps plan around $250/month, and Site Solver starting near $8,000/year, with custom Enterprise pricing above that. The jump to Site Solver is where most professional configurator power lives.

Where it fits

Use TestFit at the deal / pro-forma stage, integrated with AutoCAD, Revit, SketchUp and Excel. It is the least design-and-image tool of the five — nobody buys TestFit for renders — but it is unmatched when the question is "does this site pencil out, and how fast can we prove it."

Veras (by EvolveLAB, distributed by Chaos)

Veras is AI rendering that runs inside your modeling application. Instead of exporting to a browser, you trigger it as a plugin in Revit, SketchUp, Rhino, Forma, Archicad or Vectorworks (a web app also exists) and it renders straight from your live geometry. Its signature control is a geometry-override slider that balances strict model fidelity against freer AI invention, plus render-selection repainting and seed reuse for controlled iteration — features archviz users care about because they preserve your design instead of hallucinating a new one.

What it costs

Indicative 2026 tiers: about $59/month on a monthly named-user plan, about $612/year for a floating license, and roughly $149/year for eligible students, plus a trial of 30 renders over 15 days. Distribution is now handled by Chaos (the V-Ray/Enscape company), which signals staying power.

Where it fits

Veras is the right pick when geometry fidelity is non-negotiable and you want to stay inside your BIM/CAD tool — early concept renders, quick design-review visuals, iterating without leaving Revit or SketchUp. Its limitation is the flip side of its strength: you are tied to the host apps it supports.

LookX

LookX is a web-based AI rendering platform built on its own ArchiNet model, aimed at turning text prompts, sketches, or reference images into photorealistic renders, animations, and even 3D visualizations. Its standout features are custom model training — upload a set of images in a consistent style and generate new visuals that match your studio's aesthetic — and a Style Adapter that applies a reference image's look to your design. It also does video generation and integrates with SketchUp and Rhino.

What it costs

LookX is genuinely cheap: a free plan with 100 X-points for basic use, and paid plans from about $20/month or $199/year for unlimited generations. At that price it undercuts almost every professional rendering workflow, which is much of its appeal for students and small studios.

Where it fits

LookX is best for fast, low-cost concept visuals, mood exploration, and style-driven imagery where you value speed and volume over exact geometric control. Compared to a plugin like Veras, expect looser fidelity to your source model — great for early ideation, less so when the client wants the render to match the built scheme precisely.

Which tool for which office? Use-case recommendations

Match the tool to the job, and expect to run two or three of them together:

• You do feasibility and site strategy for developers. TestFit for the pro-forma math; Forma if environmental performance (daylight, wind, carbon) drives the scheme.
• You design repetitive building types (multifamily, offices, labs). Hypar for generative layouts and grids; Forma for the site envelope; then a renderer for presentation.
• You are an Autodesk/Revit shop. Forma is the natural early-stage tool (often already in your AEC Collection), and Veras renders straight from your Revit model.
• You are a small studio or freelancer on a budget. LookX for cheap, fast concept visuals; Veras if you need renders locked tightly to real geometry.
• You need the render to become a polished client deliverable — refined materials, upscaled resolution, walkthrough video, virtual staging. That is a post-production step none of the five above own.

Where visualization actually finishes

Here is the gap the five tools leave: Forma, Hypar and TestFit decide the scheme; Veras and LookX generate a first render. But a first render is rarely the client deliverable. You still need to fix artifacts without re-rendering, swap materials or furniture, upscale to print resolution, and often turn the still into a walkthrough video. That finishing layer — sketch-to-render, AI inpainting, upscaling, staging, and image-to-video — is exactly what Visiomake is built for, and it slots in downstream of whichever design and render tools you choose.
