Abstract: A server-based platform for text proofreading includes a network unit, a processing unit, and a storing unit. The network unit connects to a networking device to receive a document including original paragraphs with words. The processing unit connects electronically to the network unit for identifying the words from the document, converting the words into reflow paragraphs, and generating an index data based on the contrast relationship between the original paragraphs and the converted reflow paragraphs. The storing unit connects electronically to the processing unit for storing a reflow document including the reflow paragraphs. The processing unit generates a proofread webpage including a first window and a second window. When the processing unit receives a referencing command from the networking device via the network unit, the original paragraphs and the corresponding reflow paragraphs are displayed on the first window and the second window respectively according to the index data.
