Verification notes

Shutdown: The operator’s July 13, 2026 notice explicitly confirms that the named service ended on March 31, 2026. July 13 is a later confirmation and domain warning, not the unknown first shutdown-announcement day. The actual cutoff hour and time zone are unknown. Original releases establish a complete independent cloud workflow: input a draft or import Word, Excel or PowerPoint text, receive AI context-sensitive corrections, and configure terminology and team rules. Public alpha and commercial Free/Pro versions count once, not separate products or models. The former iwi-ai.com domain was subsequently acquired by an unrelated third party; its present content is neither a revival nor evidence of product ownership. This record links the safe original IWI product-release page, and does not claim an exclusive currently owned old domain. The operator’s other products continue. Tokyo is an evidenced operator-headquarters fallback, not a product-specific office. The identity asset deliberately uses the original operator’s native IWI wordmark, not the repurposed domain’s material. No former-domain visit, sign-in, software download or proofreading execution was performed. Closure source
