Compatible with your favorite architecture software
Export any viewport, axonometric, sketch or floor plan from your existing tools — Luw.ai turns it into a photoreal architectural render. No plugins, no install.
01 — Sketch to Render AI
From hand sketch to photorealistic architectural render
Drop in a napkin sketch, line-art elevation or SketchUp viewport. The AI infers depth, materials, lighting and context — and returns a photorealistic architectural visualization in under 10 seconds. Iterate with one-click style variations until your concept lands with the client.
- ✓ Works with hand sketches, line drawings, axonometrics & perspectives
- ✓ Geometry-locked: AI preserves your architectural intent
- ✓ 4K output (up to 8K), instant material & lighting variations
02 — AI Interior Design from Photo & Photo-to-Render
AI interior design from photo — restyle any architectural photo in seconds
luw.ai restyles any architectural photo with AI. Upload a site photo, an existing room, or a raw SketchUp/Revit render, and the AI swaps materials, lighting, time-of-day and surroundings while preserving the original geometry. With 40+ architectural styles it suits client pitches, planning boards, competition entries and virtual staging.
- ✓ 40+ architectural styles (modern, brutalist, minimalist, biophilic, japandi…)
- ✓ Material swap: concrete, timber, brick, glass, stone, metal
- ✓ Day/night, sunny/overcast, dusk & golden hour lighting
03 — AI for Floor Plan & 3D Floor Plan
AI floor plan generator & 3D floor plan rendering — no Lumion required
Luw.ai is the only AI for floor plan work that goes both directions: generate clean 2D floor plans from a brief or hand sketch, or convert your existing CAD floor plans into rendered 3D floor plans and photoreal interior/exterior views. Free floor plan AI for early-stage concept work, schematic design and selling the dream before construction starts.
- ✓ AI floor plan generator from brief or hand sketch — free tier included
- ✓ 2D floor plan → 3D floor plan + photoreal interior in one step
- ✓ Export up to 8K renders, isometric views & client-ready boards
04 — Exterior Architecture Rendering
Exterior renders that win the pitch
Façade studies, urban context, landscape integration, planning submissions — all from a SketchUp viewport, Revit export, hand sketch or site photo. Cinematic AI rendering for residential, commercial and urban architecture.
- ✓ Single-family, multi-family, commercial & mixed-use
- ✓ Add context: trees, cars, people, sky, neighborhood
- ✓ Façade material studies in seconds, not days
05 — luw.ai Studio
Studio — design in 3D and render on one canvas
luw.ai Studio is a browser-based 3D building editor with AI render built in. Most AI tools take a screenshot of your model; Studio is the model. Build multi-storey buildings, curved walls, columns, stairs and roofs, then render any view photorealistically without leaving the canvas — or walk through it in first person.
- ✓ Build — walls, 9 door types, 10 window types, 7 roof types, parametric columns
- ✓ Furnish — 150+ catalog items, placed with code-level rules
- ✓ Render & Walk — first-person walk mode, 8K render from the same view
06 — Archiagent
Archiagent — the first self-auditing AI architect
Archiagent is an AI agent that designs and checks its own work. Give it a brief — "a 1-bed, 80m² apartment, kitchen on the south wall" — and it draws the rooms to scale, places every fixture by architectural rules, then audits the plan in 2D for door-swing arcs, clearances and collisions. Most AI guesses; Archiagent verifies.
- 1. Brief → natural language in
- 2. Build & furnish → rooms + items, code-level placement
- 3. Self-audit → mandatory 2D pass, red swing arcs, zero clearance violations
07 — ArchiGPT & AI Concept Design Architecture
The best AI for architecture concept design — your AI co-architect
ArchiGPT is purpose-built for architectural reasoning and AI concept design: brief-to-concept, programme analysis, façade composition critique, materials advice and reference image generation. Trained on architecture — not generic AI art. The best AI for architecture brief work, not just rendering.
- ✓ Brief → concept moodboard in 30 seconds
- ✓ Critique on proportions, rhythm, hierarchy
- ✓ Material & style references with one-click render

What architects say about Luw.ai
"We were paying a render farm $400 per board and waiting 48 hours. Luw.ai gives me a better-looking render in ten seconds from a SketchUp viewport. We won three pitches this month using it."
"I was a Lumion power user for six years. I haven't opened it in four months. Luw.ai is faster, the materials look better out of the box, and there's no rendering queue eating my evenings."
"As an architecture student, I can't afford V-Ray or D5 Render. The free tier on Luw.ai lets me deliver studio reviews at the same quality as the firms my classmates intern at. Game changer."

Architect FAQ
Questions architects actually ask
What is the best AI for architects in 2026?
For architectural visualization specifically, Luw.ai leads the field for sketch-to-render, photo-to-photoreal restyle and floor-plan-to-3D in 2026. Unlike Lumion or D5 Render it needs no install and no GPU; unlike PromeAI it is purpose-built for architecture rather than general AI art. The free tier covers full-resolution previews so most architects can ship client boards without paying.
Will AI replace architects?
No. AI replaces the slow, repetitive parts of architectural visualization — manual rendering, lighting setup, material assignment, post-production, render-farm bills — not the design judgment, regulation, structure or client relationships that define the profession. Architects who adopt AI rendering early ship 5–10× more concept iterations and win measurably more pitches.
How does AI rendering for architects actually work?
You upload a sketch, SketchUp/Revit/Rhino viewport, axonometric, floor plan or reference photo. Luw.ai's architecture-tuned diffusion model preserves your geometry and re-paints it with photoreal materials, contextual lighting and surroundings. Render time is typically under 10 seconds at 4K (with up to 8K available). You can lock geometry, restyle materials, swap time-of-day or apply Magic Wand region edits.
Can I use Luw.ai with SketchUp, Revit, Rhino, ArchiCAD, 3ds Max or Blender?
Yes — every major architecture tool. Export any viewport, axonometric, elevation or sketch as JPG/PNG (or use a 2D plan from AutoCAD/Vectorworks/Chief Architect) and drop it into Luw.ai. The AI preserves your geometry and applies photoreal materials, lighting and context. No plugin install required.
Is there a free AI rendering tool for architects?
Yes. Luw.ai's free tier includes daily renders, full-resolution previews and every architectural style. No credit card required. Architecture students get extended free access — perfect for studio reviews, thesis projects and portfolio work.
Can AI generate a photorealistic render from just a hand sketch?
Yes. Sketch-to-render is one of the most popular workflows on Luw.ai. Upload a napkin sketch, concept drawing or line-art elevation — even a phone photo of paper. The AI infers depth, materials, lighting and surrounding context to produce a photorealistic architectural visualization. See Sketch AI for the dedicated workflow.
Can AI generate floor plans?
Yes. Luw.ai's AI floor plan generator turns a brief or hand sketch into a clean 2D floor plan, and converts existing CAD floor plans into rendered 3D interior or exterior views — useful for schematic design, client communication and real-estate marketing.
Luw.ai vs Lumion vs D5 Render vs V-Ray vs Enscape vs PromeAI — which should I pick?
Lumion, D5 Render, V-Ray and Enscape are traditional 3D rendering engines — they require a paid licence, a powerful GPU, plugin setup and a learning curve measured in days to months. PromeAI is general-purpose AI art with some architecture presets. Luw.ai is the only option built end-to-end for architects with cloud rendering (no install/GPU), sub-10-second turnaround, a free tier and architecture-specific tooling (sketch-to-render, floor-plan-to-3D, ArchiGPT). Many studios run Luw.ai alongside Lumion/D5 for early concept work and switch to the traditional pipeline only for final hero shots.
Is Luw.ai suitable for planning permission boards and client presentations?
Yes. Renders are 4K standard with up to 8K available, photoreal and consistent across iterations — suitable for client pitches, planning permission submissions, heritage consultation, real-estate off-plan marketing and competition entries. Use Enhance AI to upscale further for billboard-size prints.
Can the AI render exteriors as well as interiors?
Yes — both with dedicated workflows. See Exterior AI for façade studies, urban context and landscape integration, and Interior AI for room-by-room photoreal interior architecture.
Which AI tools for architects are actually worth using?
The shortlist of AI tools for architects that actually save studio time: an AI rendering engine purpose-built for architecture (Luw.ai Render AI), an AI floor plan generator (Luw.ai's AI for floor plan workflow), sketch-to-render (Sketch AI), an AI for architectural visualization that locks geometry (Interior AI & Exterior AI), and an AI co-architect for concept design and critique (ArchiGPT). Avoid general-purpose AI image generators — they ignore your geometry. Avoid AI tools for architects that are just GPT wrappers — they don't render.
What is the best AI for interior design in 2026?
For architects and interior designers who need to deliver client work, the best AI for interior design in 2026 is one that locks your room geometry, restyles materials photorealistically, supports AI interior design from photo input, and offers a free tier — see Luw.ai's dedicated Interior AI page. For pure inspiration moodboards, general AI image tools work; for delivery, only geometry-aware AI room design and AI home design tools produce usable, consistent output.
How is this different from Midjourney, DALL·E or generic AI image generators?
General AI image generators produce pretty pictures but ignore your geometry — every iteration is a different building. Luw.ai's models are tuned for architecture and lock to your input geometry, so the building you designed is the building that renders. That's the difference between concept art and architectural visualization.
Do you offer a discount for architecture students and schools?
Yes — architecture students get extended free access and architecture schools can request classroom plans. Email us with your .edu address or student ID. Many of our most-loved features were built after listening to studio crit sessions.
