WillGate Enhances TACT SEO with AI-Fact Checking Functionality

WillGate, headquartered in Minato, Tokyo and led by CEO Riki Kojima, has announced the addition of a new feature to its AI and SEO tool, TACT SEO. This tool not only facilitates easy SEO article creation but now also allows for AI-powered fact-checking of the content produced.

Overview of the New Feature

With this update, TACT SEO enables users to verify the accuracy of AI-generated content. The fact-checking process analyzes the entire article, presenting results categorized into three different verdicts based on the comparison with reference sites:

- Accurate: The article's content is confirmed as correct based on the information from reference sites.
- Inaccurate: There is a discrepancy between the reference information and the article's content.
- Indeterminate: There are insufficient sources to provide a conclusive judgment.

Additionally, users can easily access the source sites for further analysis. Any content that requires revision can be rewritten swiftly with a single click, taking only about ten seconds to adjust.

Expected Benefits

This innovation significantly reduces the manual effort involved in content verification after article creation. Although the AI writing feature had already streamlined the article creation process, the necessity for manual fact-checking had extended the time required before publication. With the new automated AI fact-checking, articles can now be published much faster with significantly reduced labor hours.

Success with AI Rewrites

Approximately 60% of articles rewritten with TACT SEO achieve placement within the top 10 search results. The media division of WillGate has experienced numerous instances of rank improvement thanks to these AI-assisted revisions.
