Whatzit is a secure platform tailor-made for spine implant identification. 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. Please keep in mind as you use the Whatzit app that modern mobile applications are incredibly difficult to build and just as difficult to maintain.
