MNKI
Sketch to Render with AI — Photorealistic in Seconds
Last updated: July 28, 2026
How MNKI turns a sketch into a render
Architectural visualisations traditionally take hours of modeling and rendering in 3D software. MNKI streamlines the concept phase into a simple 3-step AI workflow:
1. Upload Sketch
Drop in your hand drawing, iPad line sketch, or CAD line export. MNKI preserves your perspective, windows, and structural boundaries.
2. Select Style & Prompt
Choose from over 30 architectural styles—such as Brutalist, Japandi, Scandinavian, or Modern Glass—or enter a custom material prompt.
3. Generate & Inpaint
Receive high-resolution renders in seconds. Use MNKI's inpainting tool to restyle specific materials, lighting, or furniture without re-rendering.
Architectural styles you can apply
MNKI supports both interior and exterior architectural styles out of the box:
- Modern Minimalist: Clean concrete, floor-to-ceiling glass, and warm wood accents.
- Japandi & Wabi-Sabi: Natural linen, muted earth tones, curved plaster walls, and organic lighting.
- Biophilic & Tropical: Integrated greenery, wood slats, water features, and soft natural sunlight.
- Industrial Luxury: Exposed dark metal, brickwork, polished screed floors, and warm ambient lighting.

Frequently asked questions
How does MNKI turn a sketch into a photorealistic render?
MNKI uses specialized AI models trained on architectural design and materials. You upload a hand-drawn sketch or 2D CAD outline, select a design style, and MNKI generates a photorealistic render preserving your spatial layout and proportions in under 60 seconds.
What type of sketches work best with MNKI?
MNKI accepts hand sketches, pencil drawings, iPad drawings, AutoCAD elevation exports, SketchUp line captures, and rough napkin drafts. Clear lines and visible spatial geometry yield the most accurate renders.
Is MNKI free to try for sketch-to-render?
Yes, MNKI is free to start. The free plan provides 40 credits with no watermark and no credit card required. You can render your first sketch instantly in the browser.
