8 Best Tools to Turn a Sketch Into Render Using AI | 2024 Update

Written by Kacper Staniul

In the early conceptual design phases of architectural and interior design projects, hand-drawn sketches and diagrams are commonly used to explore initial ideas and concepts.

However, translating those rough 2D sketches into detailed and realistic 3D visualizations traditionally requires specialized 3D modeling skills and rendering software, slowing down the iterative design process.

Recently though, AI has emerged as a powerful new tool for architects, enabling basic sketches to be turned into photorealistic 3D renderings within literally seconds through modern machine learning algorithms.

Below, we list some of the top sketch to render AI tools, that allow architects and interior designers to quickly generate conceptual 3D scenes directly from hand drawings or CAD models.

Best sketch to render AI software

MyArchitectAI

If you're looking to generate an unlimited number of design ideas from your architectural sketches, look no further.

MyArchitectAI's style transfer feature is a game-changer for the early conceptualization stage of projects, letting you turn simple sketches or CAD models into photorealistic 3D renders in under 10 seconds.

By uploading hand-drawn architectural sketches or models, the AI engine automatically generates realistic renderings by recognizing lines and shapes in your designs.

Here's how you can render your sketch in MyArchitectAI:

1. Sign up for a free account here

2. Upload your sketch

3. Upload a reference image you'd like the app to use as inspiration or select a preset from the style gallery

4. Adjust the style strength depending on how closely you want the generated design to look like the reference image you picked

5. Click the "generate" button to render your sketch

Additionally, you can fine-tune the details in your image using text prompts:

The whole process runs in your browser, which means you don't need a powerful computer (unlike with traditional rendering tools).

This allows architects and interior designers in the early design stage to quickly explore multiple design options and visualize their ideas in 3D before committing to pixel-perfect modeling.

Pricing: generate 10 renders for free. After that, a $29/month plan gets you unlimited renders.

Interior AI

InteriorAI is an AI image generator that lets architects and interior designers render their sketches and CAD models, real estate agents do virtual staging, and homeowners find ideas for interior remodeling.

The app is very easy to use: simply upload your sketch as a JPG or PNG file, select your desired aesthetic and settings, and click the "render" button. Your 3D visualization will be ready to download in less than a minute.

Aside from still images, InteriorAI can also generate interactive 3D flythroughs of spaces for more detailed review.

The biggest cons of InteriorAI are inaccurate rendering and a lack of free testing plans.

Pricing: starts at $39/month for 1,000 generations a month. No free plan available.

Sketch2Render

Sketch2Render is a very simple AI sketch to render app that takes hand-drawn 2D architectural sketches as input.

By uploading sketches, the AI engine analyzes the geometry of the design and automatically generates 3D renders with decent accuracy and realism.

Pricing: 10 renders a month are free. Premium plans start at $49/month.

Fabrie

Fabrie's AI Imagine tool allows architects to generate conceptual 3D scenes from sketches and text prompts, providing another path for early ideation and exploration.

By typing parameters like the building style and key features, Fabrie's AI engine takes sketches to renders within seconds. This rapid generation allows exploring many more concepts before advancing designs further.

Their generous free plan makes Fabrie suitable for personal or educational use.

Pricing: Fabrie AI is still in beta stage and you can try it for free with 300 credits a day

LookX

LookX lets you take your design concept from sketch to render in a matter of seconds using its versatile AI engine.

It has two modes: image and video. The first one creates 3D visualizations from either a sketch or text prompt alone, and the latter animates your existing renders or creates a video from from a text prompt.

LookX also has SketchUp and Rhino plugins that let you visualize your concepts right inside these CAD tools.

Pricing: Lookx has a free plan with limited features and unlimited paid plans that start at $20/month.

ArchiVinci

ArchiVinci has three sketch rendering modes: interior, exterior, and masterplan, which are optimized for these visualization types and cater to both architects and construction firms.

It lets you specify your exact needs using a custom prompt and define the level of creativity their AI engine will apply using the similarity level option.

It also offers a virtual staging feature for filling empty spaces with furniture, and inpainting mode for selectively modifying parts of your renders.

Pricing: first 3 renders are free. Then plans range from $10 to $270.

Architect AI

Architect AI's rendering tool accepts hand-drawn sketches, diagrams, or 3D models as input for the AI sketch to render system to automatically visualize 3D building models with decently accurate dimensions and layouts at a conceptual level of detail.

This allows architects to leverage AI to turn basic sketches into rendered presentations and documents more efficiently.

Pricing: you can turn the first 10 sketches to renders for free. After that, credits start at $1.99 per 10 credits.

ArchitectRender

ArchitectRender is another easy-to-use solution that lets you upload your architectural models or sketches for the AI software to generate 3D scenes and photorealistic renders. This allows users to produce client-ready visuals directly from basic sketches or diagrams early in the design process.

Pricing: 5 credits are free, then each credit costs $1. The more credits you purchase, the lower the price.

Common questions about sketch to render AI tools

How to turn an architectural sketch into a 3D render using AI?

The rendering process using AI-based software is much more straightforward than when using traditional solutions. All you need to do is upload your sketch or CAD model to the app, select your desired settings from a simple user interface (usually sliders and dropdown options), and hit the generate button.

How long does it take to generate an architectural AI render from sketch?

Most AI rendering tools will create a sketch rendering in 10-20 seconds. Occasionally, this process may take up to 2 minutes when the rendering engine needs to "warm up" which is a way to describe the optimization stage of the underlying machine learning model. In any scenario, the process is by a couple magnitudes faster compared with traditional rendering tools.

How much does it cost to render a sketch with AI?

Prices range from $19 to $49 per month and give you the ability to render an unlimited number of sketches. Many sketch to render tools offer free testing accounts, so you can generate a few visualizations before subscribing to a paid plan.

What to look for when evaluating AI sketch rendering tools?

There are a couple of aspects you should check before subscribing to a paid plan:

  • If the rendering software has a free plan to let you "try before you buy".
  • How much control does it give you over the output - it should allow you to provide a prompt (custom text instructions).
  • If a style transfer feature is available - to let you use your own reference images
  • How photorealistic the renders are.
  • If you get full commercial rights to the created images.
  • If your sketches and visualizations are kept private and not shared online by the sketch rendering app developer.
  • What is the resolution of the generated images (many apps let you upscale your images).
  • How frequently the developer adds new features and improvements to the app (a public roadmap is usually a good indicator).
