Kanai

A one-sentence summary

Kanai is an AI-based application for interior design and 3D space visualization, developed by Kanai, LLC. It allows users to scan real rooms, create furniture models, edit space layouts, and view different decoration styles through AI-generated visuals.

What is Kanai?

Kanai integrates phone scanning, conversion of 2D images into 3D models, room editing, and generative interior design into a single mobile workflow. Users can first create room models that reflect real-world geometric relationships, and then add furniture and adjust materials and sizes, which helps to overcome the difficulties associated with judging the appearance of a space based solely on 2D images.

This article deals with the Kanai 3D interior design application; it is not related to marketing automation, AI governance, or other software with similar names. The current version of this product is offered by Kanai, LLC within the Apple app ecosystem.

Overview of main functions

3D room scanning

The user uses the device’s camera to slowly move around the room, covering key areas such as tables, chairs, sofas, and corners; the application then creates a model of the space based on this information. The new scanning process shows the progress of processing and is compatible with devices that are not of the Pro version.

• Identify the boundaries of walls, doors, windows, and floors.
• Record the existing objects in the room and their spatial relationships.
• On supported Pro devices, hardware more suitable for spatial perception is utilized.
• Non-Pro devices can also be used for scanning, but the quality and stability of the models may vary.
• The scan results can serve as a basis for determining the arrangement of furniture and for creating AI-generated previews of the space.

How should scan accuracy be understood?

Room models are useful for conceiving decorations and previewing the fit of furniture, but they cannot be used as a substitute for architectural drawings, construction plans, or documents related to structural safety. Important dimensions should still be verified using reliable measuring tools, and the construction of custom cabinets and other fixed installations should be checked by professionals.

Convert furniture images to 3D

Users can upload pictures of furniture, and the system converts them into 3D models that can be incorporated into room layouts. This process is useful for adding sofas, tables, lighting fixtures, or decorations from product catalogs to one’s own space designs.

• Try to choose furniture images with a complete subject and a clean background.
• Avoid photos that are heavily obscured by other objects.
• After the conversion is complete, check the model’s outline and proportions.
• Even after using automatic size recognition, it is still necessary to verify the actual specifications of the product.
• Compare different placement positions by rotating, scaling, and moving.

2D images are unable to show the back side of an object, its internal structure, or its actual material properties; as a result, the models generated may contain inferred information. They are suitable for visual decision-making, but they are not equivalent to high-quality 3D assets used in manufacturing.

AI Studio-style renderings

AI Studio allows users to upload photos of a room and select a style direction, after which it generates a realistic preview of the interior after renovation. It is useful for comparing colors, atmospheres, and decorative elements before actually purchasing furniture or starting construction work.

• Generate a new interior style preview based on room photos.
• Select the design direction from the predefined style set.
• Use multiple renderings to compare different decoration ideas.
• Understand spatial awareness through a first-person, immersive perspective.
• Share the renderings with fellow residents or designers for discussion.

AI-generated renderings may alter the proportions of a space, the location of doors and windows, the lighting conditions, or the details of the furniture. Users should consider them as conceptual drawings, rather than designs that can be implemented exactly as shown.

Room and Furniture Editing

The project editor allows for moving, rotating, and scaling furniture, and it includes tools such as measurement functions, texture handling, and surface alignment. When the furniture is close to walls, floors, or other surfaces, this alignment feature reduces the difficulty of manually positioning it.

Complete usage process

1. Install the app and create an account to save personalized settings and manage projects.
2. Select room scanning, move the device slowly and cover the corners, doors, windows, and major objects.
3. Wait for the room model to be processed, and check for missing areas and obvious geometric errors.
4. Upload furniture images to create 3D models, or use the furniture already available in the project.
5. Drag the furniture into the room and adjust its position, orientation, size, color, and texture.
6. Copy the project to create multiple versions, and compare the channels, proportions, and overall visual effect.
7. When looking for style inspiration, submit room photos to AI Studio to generate renovation previews.
8. Share the plan and gather feedback; verify all key dimensions once more before purchasing or starting construction.

How to improve the quality of scanning and generation

1. Maintain even lighting in the room, and avoid strong backlighting as well as large reflective surfaces.
2. Move slowly during scanning to ensure that corners and large objects are covered from multiple angles.
3. When adapting furniture images, it is best to use clear, unobstructed pictures with the entire object visible, either from the front or at an angle.
4. After the model is completed, check the outlines of the walls, doors, windows, floors, and furniture first.
5. Compare the length, width, and height of the actual product with those of the model, item by item.
6. Create separate projects for different layouts to prevent overwriting older versions that can be compared.
7. Mark separately the structural changes, non-purchaseable items, and abnormal details in the AI-generated renderings.
8. When construction, customization, and safety distances are involved, it is necessary to have professionals conduct on-site rechecks.

Which users are it suitable for

• New homeowners who are preparing to move in and planning the placement of their furniture.
• Consumers who want to determine whether sofas, tables, or cabinets match well with each other before making a purchase.
• Users who need to discuss the layout with a partner, roommate, or family member.
• Interior design enthusiasts who can quickly create conceptual plans.
• Design professionals who need to present preliminary ideas for the space to clients.
• Homeowners who are interested in comparing a variety of colors, textures, and decoration styles.
• Users of Apple devices who wish to combine phone scanning with tablet editing.

Typical use cases

Price and subscription

The price information was verified on August 23, 2026; the actual amounts, taxes, exchange rates, and discounts may vary, and the final figures will be those displayed on the settlement page.

The app can be downloaded for free, with in-app purchases available through Kanai Designer. In the United States, two pricing options are listed: 4.99 dollars and 49.99 dollars; however, the official store page does not specify the billing period for these options.

The price varies depending on the country, taxes and fees, the currency, and the region of the Apple account. Before making a purchase, it is necessary to check within the app the subscription period, automatic renewal options, free trials, cancellation policies, and the features available; one should not assume whether the payment is monthly or annual based solely on two amounts.

Platform and device requirements

The app supports multiple languages, including Simplified Chinese, English, French, German, Japanese, and Spanish. Whether the specific functions are identical on all devices depends on the actual interface after installation.

Accounts, Synchronization, and Sharing

The account is used for personalization, project management, cross-device synchronization, and managing payment plans. Users can scan rooms on their smartphones and then use tablets under the same account to continue with the design work.

• Project synchronization depends on an account and a network connection.
• The scan results can be copied to create different design options.
• You can share project ideas or multiple Studio renderings.
• Joint discussion is not equivalent to a complete multi-user permission and version management system.
• For important projects, the dimensions, purchase list, and records of manual verification should be retained.

Privacy and data processing

Kanai handles the room images captured by the cameras, the images of furniture used for conversion, as well as account management information. 3D scanning and the process of converting 2D data into 3D format are carried out in the cloud, and third-party interfaces are utilized for furniture conversion.

According to the privacy guidelines of app stores, user-provided information such as name, email address, as well as photos and videos can be linked to an individual’s identity. Room listings may reveal details about an address, valuable possessions, and living habits; it is therefore necessary to remove any unnecessary sensitive information before uploading them.

Content ownership

Users retain ownership of the original scans and images they submit, while granting Kanai the permission to use, process, and store such content for the purpose of providing and improving services. Before designing something for a client’s project or for commercial use, it is necessary to confirm the rights regarding the generated content, as well as any images of third-party furniture and brand materials.

API, GitHub, and open-source status

To date, there are no Kanai APIs, SDKs, or official open-source repositories that have been made available to ordinary developers. Applications and cloud-based processing services should be considered closed-source commercial products; they cannot be labeled as open source just because they make use of third-party interfaces or Apple’s system capabilities.
