Which AI Is Best for Interior Design in 2026?

Best AI for Interior Design Overall

Each platform was tested on its highest-quality model or plan. A platform’s overall score is the average of its scores across the eight tasks in our study, with each task weighted equally. In the table below, we rank the ten platforms from highest to lowest.

Interior Design Scores by AI Platform (September to October 2026)

Rank	AI Platform	Model or Plan Tested	Overall Score	Strongest Task
1	Google Gemini	Nano Banana Pro	89.1	Style Matching
2	ChatGPT	GPT Image 2 (Thinking)	88.0	Color and Material Palettes
3	HomeDesigns AI	Expert plan	84.3	Room Redesign From a Photo
4	Planner 5D	Professional plan	82.6	Floor Plans and Space Planning
5	Grok	Grok Imagine Image 2.0	82.3	Room Redesign From a Photo
6	Microsoft Copilot	MAI-Image-2.5	82.1	Color and Material Palettes
7	Interior AI	Premium plan	82.0	Virtual Staging
8	REimagine Home	Pro plan	81.3	Virtual Staging
9	Meta AI	Muse Image	79.4	Style Matching
10	Midjourney	Midjourney V8.2	78.6	Architectural Renderings
Not ranked	Claude	No image model	N/A	Does not generate images
Not ranked	DeepSeek	No image model	N/A	Does not generate images

Our researchers took three main points from this data:

• We found that Google Gemini’s lead comes from strong results on every task. It finished first or second in seven of the eight tasks, and its lowest task score (84.1, for floor plans) was higher than the floor plan score of every platform except Planner 5D.
• HomeDesigns AI was the highest-ranked dedicated design app, in third place at 84.3. It beat both Google Gemini and ChatGPT on room redesigns from a photo but trailed them on floor plans, sourcing and architecture.
• Midjourney ranked last overall (78.6) even though it led architectural renderings. It scored 62.7 on floor plans and 64.1 on furniture sourcing, the two lowest task scores in the study.

Best AI for Each Interior and Architectural Design Task

The requests in our study were split evenly across eight tasks, with 60 requests per task. Five tasks focused on interiors, and the other three covered floor plans, exteriors and architectural renderings. The first table below shows the winner and runner-up for each task. The second table and the heat map that follows show every platform’s score for every task, with the top score in each column in bold.

Best AI Platform for Each Design Task (September to October 2026)

Design Task	Best Platform	Score	Runner-Up	Score
Room Redesign From a Photo	HomeDesigns AI	91.4	Google Gemini	90.6
Virtual Staging	Interior AI	91.8	REimagine Home	90.1
Style Matching	Google Gemini	91.2	ChatGPT	89.4
Color and Material Palettes	ChatGPT	90.8	Google Gemini	89.7

Architectural Renderings	Midjourney	90.2	Google Gemini	88.8

Interior and Architectural Design Scores by Task and AI Platform (September to October 2026)

AI Platform	Room Redesign	Staging	Style Matching	Palettes	Floor Plans	Sourcing	Exteriors	Renderings
Google Gemini	90.6	88.4	91.2	89.7	84.1	90.3	89.5	88.8
ChatGPT	88.9	86.7	89.4	90.8	83.6	88.9	87.6	87.9
HomeDesigns AI	91.4	89.6	87.8	84.2	78.4	80.7	82.9	79.6
Planner 5D	80.3	82.4	79.6	83.1	92.4	84.7	76.8	81.3
Grok	84.6	82.9	83.8	82.4	76.9	79.6	84.3	83.7
Microsoft Copilot	83.1	81.4	82.7	85.6	77.8	83.9	81.6	80.9
Interior AI	89.7	91.8	85.9	82.6	74.3	76.8	78.4	76.2
REimagine Home	87.2	90.1	84.6	81.9	72.8	78.5	80.2	75.4
Meta AI	82.4	80.6	84.1	81.3	71.6	77.2	79.8	78.4
Midjourney	78.2	74.6	86.9	83.4	62.7	64.1	88.6	90.2

Here is what our team took from the task-level results:

• We found that six different platforms won at least one task. Google Gemini won three, and the dedicated design apps won three between them.
• Floor plans and space planning produced the widest gap of any task, 29.7 points between Planner 5D (92.4) and Midjourney (62.7). Furniture and decor sourcing was next at 26.2 points, because Google Gemini linked its picks to products sold in real stores while Midjourney can only show furniture in a picture.
• ChatGPT led color and material palettes (90.8). Judges said its palettes came with the clearest notes on paint names, finishes and where to use each material.

Accuracy: Room Structure, Scale and Floor Plan Dimensions

A redesign is only useful if it shows your actual room. For every redesign that started from a photo, our panel checked whether the walls, windows and doors stayed where they are in real life, and whether the new furniture was drawn at a size that would fit the space. For every floor plan, we measured the room dimensions against the true measurements we supplied. The table below is sorted by the share of redesigns that kept the room’s structure.

Design Accuracy by AI Platform (September to October 2026)

AI Platform	Kept the Room’s Structure	Furniture at Realistic Scale	Floor Plan Dimensions Within 5%
HomeDesigns AI	95.2%	90.4%	71.3%
Interior AI	94.6%	92.7%	64.8%
Google Gemini	93.7%	91.2%	84.6%
REimagine Home	93.1%	88.3%	62.5%
ChatGPT	91.8%	89.6%	82.9%
Planner 5D	88.4%	95.6%	96.8%
Microsoft Copilot	86.7%	85.1%	73.9%
Grok	84.3%	83.7%	70.2%
Meta AI	82.9%	81.4%	61.7%
Midjourney	61.3%	74.8%	38.6%

Our researchers drew three conclusions from the accuracy data:

• We found that HomeDesigns AI kept the room’s structure in 95.2% of redesigns, the highest rate in the study, followed by Interior AI at 94.6%.
• Planner 5D drew 96.8% of floor plans within 5% of the true dimensions, well ahead of Google Gemini (84.6%), because it builds plans from measurements instead of generating a picture.
• Midjourney kept the room’s structure in only 61.3% of redesigns, so it works better for mood and style ideas than for planning changes to a real room.

Best AI for Design Advice Without Images

Many people use AI chat to plan a room in words: how to arrange furniture, which colors work together, what a project will cost and whether a change needs a permit. We asked seven AI chatbots the same 160 written design questions, 40 for each of four types of advice, and the same panel scored each answer from 0 to 100. This test includes Claude and DeepSeek, which do not generate images.

Design Advice Scores by AI Chatbot (September to October 2026)

AI Chatbot	Model Tested	Layout Advice	Color and Material Advice	Budget and Shopping Plans	Renovation Questions	Overall
Claude	Claude Opus 5.5	91.2	90.6	88.4	92.3	90.6
ChatGPT	GPT-6 Sol	90.4	91.1	89.7	89.8	90.2
Google Gemini	Gemini 4 Argon	89.1	89.6	91.4	88.2	89.6
Microsoft Copilot	GPT-6 Astra	85.6	86.2	87.1	85.3	86.0
Grok	Grok 4.6	83.9	84.7	82.6	82.1	83.3
DeepSeek	DeepSeek V4-Pro	82.7	81.9	80.3	83.4	82.1
Meta AI	Muse Spark	81.2	83.4	80.9	78.6	81.0

Here is what our team took from the advice results:

• We found that Claude gave the best design advice overall (90.6), winning layout advice (91.2) and renovation questions (92.3).
• Claude was the most likely to say when a change, such as removing a wall or moving plumbing, needs a permit or a licensed professional.
• Google Gemini led budget and shopping plans (91.4), using current prices from Google Shopping, while ChatGPT led color and material advice (91.1).

Best AI Models and Plans for Interior Design, Including Free Options

What you get often depends on your plan. We tested 13 models and plans across the ten platforms, including each platform’s free option where one exists. The table below ranks each one and lists the price of the lowest paid plan that includes it.

12	Muse Image	Meta AI	Free	79.4	Free
13	Midjourney V8.2	Midjourney	Paid	78.6	$10/month

Our team took three main points from the model-level results:

• We found that Nano Banana 2 in Google Gemini is the best free AI for interior design, scoring 86.4, higher than every paid option outside the top three.
• Upgrading Google Gemini to Nano Banana Pro added 2.7 points, mostly from better floor plans and more accurate room structure.
• Planner 5D’s free plan scored 80.6, 2.0 points below its Professional plan, because free users get about half of the furniture catalog.
