TryDiff is a free text comparison tool. Paste or upload files, hit Compare, and get a clean side-by-side diff with changes highlighted at the line and character level. No signup, no install, no data stored on our servers. We built TryDiff because existing diff tools are bloated desktop apps, paywalled SaaS, or ad-heavy websites. TryDiff is fast, clean, and works on any device — desktop or mobile. 100% free, always.
