Featuring the proprietary TextScrub auto-redaction technology, Whatzit is the ONLY secure way to post X-rays for crowdsourced feedback. What is TextScrub? Exclusive to Whatzit, TextScrub technology uses AI, computer vision and other proprietary processes to automatically redact text from X-rays prior to being posted in the Whatzit app. This lightning fast process takes place completely on your device without any communication with Whatzit's cloud-based servers. Un-redacted X-rays with potentially sensitive information should never leave your device.
