Text diff checker online — compare two texts instantly
Need to spot what changed between two versions of text? Our free text diff checker online highlights every difference instantly. Paste your original text on one side and the updated version on the other, and it shows exactly what was added, removed, or changed — line by line, and right down to the individual words within a line. No more squinting to find the one edit that matters.
Switch between a side-by-side view and an inline unified view, and fine-tune the comparison by ignoring case or whitespace when you only care about real changes. A clear summary tells you how many lines were added and removed at a glance. Whether you're comparing drafts, reviewing code or config changes, checking edits to a document, or proofreading, the differences jump straight out. Simply paste two texts to compare them instantly. No sign-up, no downloads, no limits — just clear results, privately.
