About This Launch
TextCompare is a free online diff checker that finds the differences between two texts, files or code snippets. Paste or drop two versions and it highlights added, removed and changed lines, with line, word and character-level modes and side-by-side or inline views. It also compares Excel, CSV, Word, PDF, images, JSON, XML and source code. Everything runs locally in your browser: nothing is uploaded, no sign-up.
Why I Built This
We needed a quick, private way to compare documents and code without uploading sensitive text to a server, so we built a diff checker that runs fully in the browser.
