Questions & Answers

As answered by people managing DiffMerge and TextCompare.me.

What makes your product unique?

TextCompare.me's answer:

TextCompare.me brings IDE-grade diff quality to the browser. Its comparison engine is ported from IntelliJ IDEA's diff implementation (Myers LCS with smart change correction), refined with word-level highlighting — the same quality developers trust in their IDE, now available online for free. Everything runs locally in your browser: your text never leaves your device unless you explicitly create a share link. It's also fully bilingual (English/Chinese) and works great on mobile.

Why should a person choose your product over its competitors?

TextCompare.me's answer:

  • Better diff quality — most online tools show raw minimal diffs that look confusing; TextCompare.me optimizes results the way IntelliJ IDEA does, so changes read naturally.
  • Privacy by default — comparison happens 100% client-side; no uploads, no accounts, no tracking of your content.
  • No friction — it's free, unlimited, no sign-up, no ads walls, and handles large texts fast, right in the browser.

How would you describe the primary audience of your product?

TextCompare.me's answer:

Developers comparing code snippets, configs, and logs; writers and editors tracking revisions between drafts; QA engineers, translators, students, and anyone who needs to spot exactly what changed between two versions of a text — without installing anything.

What's the story behind your product?

TextCompare.me's answer:

TextCompare.me started from a simple frustration: existing online diff tools either upload your text to a server, hide features behind sign-ups, or produce diffs that are technically "minimal" but hard to read. As a developer used to IntelliJ IDEA's excellent diff view, I wanted that same quality in a browser tab — private, instant, and free. So I ported IDEA's diff engine to TypeScript, refined it with word-level highlighting, and shipped it as a simple web tool. It has been continuously improved based on real usage, including careful mobile support.

Which are the primary technologies used for building your product?

TextCompare.me's answer:

Next.js (App Router) + React + TypeScript, styled with Tailwind CSS, deployed on Vercel. The core diff engine is a TypeScript port of IntelliJ IDEA's Myers LCS algorithm, combined with the jsdiff library for character/word-level refinement. All comparison runs client-side in the browser.

Who are some of the biggest customers of your product?

TextCompare.me's answer:

  • individual developers
  • writers
  • and professionals worldwide who rely on it for quick, private text comparisons.
