Qipit is a free service for turning digital photos into sharable, online documents. It works with any photo taken with a digital camera, or from your mobile phone. Like ScanR (review), Qipit will store and host your photos, and let you rotate them to your heart's content. This works the best with shots of documents taken at an angle, and with whiteboards, business cards, etc. Once uploaded, Qipit will tweak the contrast of your shot, drawing out the text, and doing its best to correct perspective warp. Unlike ScanR however, you're not getting the archival goodness of optical character recognition to turn those notes into searchable text. Instead, it's up to you to tag your shots for easy sorting later on.
I had mixed results with the service. All my test shots with oblique angles didn't receive any perspective correction, and the two I had selected for color instead of black and white turned out harder to read than they were originally. Also, many modern-day digital cameras have text and whiteboard modes that will either help you center your shots or do correction right in the camera (such as Casio's Exilim line). For phones however, Qipit is a slightly better solution than ScanR, which requires one megapixel or higher, leaving many phones in the dust.
