14,
23,
31]. These leading platforms exemplify the growing role of AI in architecture, driving the industry toward more efficient, sustainable, and innovative practices that cover the entire architectural workflow.
However, not all listed software solutions aim to cover the entire architectural workflow, as outlined in this study; many excel in specialized tasks.

20]. These specialized tools demonstrate the diverse ways in which AI and advanced computational methods are transforming specific aspects of architectural practice, each addressing unique challenges within the design and construction process[
13,
33].
4. Discussion
The integration of AI into architecture is reshaping the field by improving efficiency, sustainability, and collaboration. The study reveals that tools such as Swapp, Spacio.ai and Autodesk Forma dominate the market due to their extensive feature sets, each addressing critical phases of the architectural process. Swapp, which focuses on automating construction documentation and BIM modeling, offers cost-effective solutions but faces criticism due to its limited real-world application and access.
Akhtar & Ramkumar (2023) similarly noted that while AI has significant potential in architectural workflows, the lack of large-scale testing and validation often limits adoption, particularly in regions where technological infrastructure is lacking [
34]. Spacio.ai, with its rapid modeling and real-time performance dashboards, leads in facilitating faster decision-making, enabling architects to efficiently navigate early-stage project development. This aligns with previous research by
Płoszaj-Mazurek & Ryńska (2024), who emphasize that AI's ability to rapidly process large datasets and provide actionable insights is crucial in promoting sustainable design practices [
10].
Furthermore, while Autodesk Forma offers environmental optimization and is closely matched with Spacio.ai in terms of features, it does not surpass it. This gap highlights a recurring theme in AI research, as observed by
Jin et al. (2024), where AI’s effectiveness is influenced by external factors such as market readiness, regulatory environments, and technological infrastructure [
6].
The gap between these top-performing tools and more specialized solutions demonstrates that the current AI landscape is fragmented, with each tool addressing a specific segment of the architectural process. This mirrors the findings of Kumar (2024), who stressed that AI tools, while transformative, are often limited in their ability to cover the entire architectural workflow comprehensively, necessitating a combination of specialized tools for maximum efficiency [
7]. For example, Midjourney and DALL-E, which excel in conceptual design visualization, and Cove.tool, which focuses on sustainability consulting, are examples of AI tools that target specific aspects of the architectural process without offering comprehensive coverage.
The regional distribution of AI software in architecture is predominantly concentrated in the US, EU, Australia, and increasingly, China. These regions benefit from advanced technological infrastructures that provide the computational resources and skilled talent necessary for AI innovation in fields like architecture and urban planning. The US, EU, and Australia have strong economies that enable significant investment in AI research and development, while China, with its government-driven initiatives and substantial tech ecosystem, has rapidly become a major player in AI technology. Economic and regulatory frameworks in these areas are generally more favorable, offering clear guidelines on data privacy, ethics, and the integration of AI technologies. This contrasts with emerging markets, where financial and regulatory barriers limit the development and adoption of AI tools. As early adopters, the US, EU, Australia, and China not only lead in AI development but also set global standards, shaping the broader market’s adoption of innovative architectural solutions.
This study provides a comprehensive analysis of AI tools in architecture, but several limitations should be acknowledged. Firstly, the research primarily relies on available literature, official product documentation, and data from selected AI tools, which may not fully capture the breadth and nuances of AI applications in the architectural industry. Additionally, the varying levels of transparency and detail in the available data for each tool, particularly regarding real-world performance and adoption, create challenges for direct comparison. This is especially evident in tools like Swapp, which, despite its potential, has limited real-world validation and user access. Consequently, there may be discrepancies in the depth of analysis between tools with extensive market presence and those with restricted or emerging usage, potentially affecting the overall comprehensiveness of the findings. Further research, including more widespread testing and industry feedback, will be necessary to refine these insights and ensure a more robust understanding of AI’s impact on architecture.
Lastly, none of the authors have any financial interests or professional affiliations with the companies whose AI tools were studied. This ensures that the research findings are unbiased and based solely on the data collected and analyzed. Further research is encouraged to explore the long-term impacts and evolving functionalities of AI tools in architecture, considering the rapidly changing technological landscape and market dynamics.
