AI Automatically Detects "What Changed?" ── Drawing Knowledge Platform "BuddyBoard" Launches Beta Version of "AI Drawing Comparison" Feature to Find Differences Between New and Old Drawings

BuddyBoard Inc. (Headquarters: Nagoya City, Mizuho Ward, Aichi Prefecture, Representative Director: Raizo Kosaka) has launched the "AI Drawing Comparison" feature as a new function of "BuddyBoard AI" on July 6, 2026, as a beta version. This feature automatically compares new and old drawings using AI to detect changes within the drawing knowledge platform "BuddyBoard." During the beta period, customers using the Enterprise Plan can use it free of charge.

It automatically pairs the new and old drawing pages that need to be compared, corrects for discrepancies in layout and scale, and then indicates which parts have been changed. Not only can you see at a glance where corrections have been made, but it also catches subtle changes like line types. This reduces the burden of comparison work that staff have traditionally done manually, preventing rework due to oversights.

Challenges in the Field

In architectural practice, many stakeholders, including design firms, general contractors, and specialized construction companies, repeatedly review and revise drawings. Drawings are modified many times according to the client's requests and the progress of deliberations, and each time, stakeholders must check for differences between the new and old drawings.

The content of the check varies depending on the role. For the prime design firm or general contractor, it's about whether the indicated revisions have been correctly reflected. For subcontractors, it's about the scope of their own revisions based on changes to architectural drawings, etc. In all cases, the task of comparing new and old drawings has been left to the individual in charge.

The more drawings there are, the heavier the burden of comparison becomes. Minor changes are more easily overlooked, which has led to discrepancies in understanding among stakeholders and rework in later stages.

What It Can Do

AI Drawing Comparison enhances the accuracy and speed of drawing checks in three steps.

First, it automatically pairs the new and old drawing pages to be compared. Even for drawing sets of hundreds of pages, the AI identifies corresponding pages, eliminating the need to search manually.

Next, it automatically corrects for discrepancies in layout and scale. Drawings may change slightly in position or scale with each revision, but the comparison is performed after correcting for these differences. Then, it detects and indicates the changed areas. Not only can you see at a glance where corrections have been made, but it also detects subtle changes that are difficult for the human eye to notice, such as changes in line type, preventing major oversights.

BuddyBoard is originally a service that allows multiple people to display the same drawing on the same screen and write on it in real-time. With AI Drawing Comparison, stakeholders can confirm the indicated changes while pointing them out on the spot, ensuring alignment before proceeding to the next stage of review or revision.

Comment from Raizo Kosaka, Representative Director of BuddyBoard Inc.

"AI Drawing Comparison was born from our customers' practical need to quickly and reliably grasp changes in new and old drawings and eliminate rework caused by unexpected modifications. BuddyBoard is a service for stakeholders in different locations to review drawings while referring to the same ones. We aim to create an environment where they can spend more time on the reviews and consensus-building that they should focus on, by reducing the burden of comparison that arises with each revision."

Ease of Implementation

AI Drawing Comparison can be used as is within the existing BuddyBoard environment. No new software installation or complex setup is required; you can start using it simply by uploading the drawings you want to compare. Since BuddyBoard is accessible via a browser, it can be used on various devices, not just tablets, but also PCs at each office, allowing real-time confirmation of the same drawings.
