Free vs paid text tools — when each is worth it
Comparing Diff Checker to paid writing tools. The honest take. Browser-based, free, no signup, runs entirely on your device.
Most inputs you work with don't justify opening Word. Diff Checker is for the in-between cases — paste, transform, paste back. Browser-local, no signup, no character limits.
Use the tool: Diff Checker — No upload, no signup, no daily limit.
Free vs paid text tools
Paid writing-assistant tools bundle dozens of features. Diff Checker does one thing and does it instantly, with no signup. Both have their place — but if you only need the one thing, Diff Checker is the lighter, faster choice.

Frequently asked questions
Can Diff Checker handle non-English text?
Yes — it uses Unicode-standard rules that work for most major scripts.
Is there a length limit?
Practically, several MB of text. Beyond that the browser starts to lag.
Can I trust the count for assignment / SEO purposes?
Diff Checker matches the published Unicode standard. Cross-check against the tool of record (Word, your CMS) if that's what's being graded against.
Will Diff Checker work offline?
Yes — once the page loads, processing happens locally with no further network calls.
