ShapeWin Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Yusuke Kamimura; hereinafter "ShapeWin"), a PR company, has launched a web tool called "Press Release Strength Diagnosis by ShapeWin" that allows users to score the communication power of their own press releases for free in approximately 3 minutes. This tool uses an AI engine to diagnose the communication power of press releases based on evaluation criteria accumulated by ShapeWin through supporting over 300 companies and refining more than 10,000 press releases, simply by inputting a PR TIMES corporate page URL.
