Microsoft is officially deprecating the similarity checker feature within Microsoft Word, a tool launched in July 2020 via Microsoft Editor that used Bing to cross-reference text with online web sources. According to reports from Neowin, the removal is scheduled to take effect on October 3, 2023, leaving students and professionals to seek alternative software for verifying text originality.
The Architecture and Lifecycle of Microsoft Editor’s Similarity Engine
When Microsoft rolled out the similarity checker in July 2020, it integrated deeply into the Microsoft Editor ecosystem across Word 365, Office 365, and Word for the Web. The underlying mechanics relied on querying the Bing search index to parse documents against live web pages. Users accessed the functionality through the Home or Review tabs by opening the Editor menu, scrolling to the similarity section, and executing a manual scan.
The system generated an overall editor score alongside a specific percentage indicating how much of the drafted text matched external web fragments. Hovering over flagged sentences allowed writers to inspect the matching source material directly. From there, users could either insert proper citations or rewrite the flagged passage to lower their similarity metric.
Impact on Academic Workflows and Content Creation
Students relied on the functionality to catch accidental plagiarism and refine their citation practices before submission. For educators, the utility provided a rudimentary scan for repeated text in student assignments. However, technical consensus always framed the feature as a baseline writing assistant rather than a robust, enterprise-grade academic integrity suite, citing limitations in comprehensive database coverage compared to dedicated institutional software like Turnitin.
What Remains in Microsoft Word After the Sunset
According to official Microsoft documentation under tracking code MC1466753, removing the similarity checker does not dismantle the broader Microsoft Editor framework. Core text editing capabilities remain fully intact. Users will continue to receive automated assistance for spelling, advanced grammar checks, and contextual style suggestions.
Microsoft has not released a granular technical explanation for retiring the feature. Industry observers point to potential shifts in product strategy, internal feature consolidation, or an effort to alleviate query loads on Bing’s web-scraping infrastructure. With the October 2023 sunset date approaching, workflows dependent on native cloud comparison will require migration to third-party integrations or dedicated plagiarism detection platforms.
