Diff Checker for writers
For writers, Diff Checker fills a gap most writers run into daily: a small text task that doesn't justify opening a heavyweight editor, but that doing by hand is error-prone. Open the page, paste, do the thing, paste back.
Common writers workflows
- Quick checks before sending — counts, capitalization, formatting
- Cleanup of pasted-in content from another source (Word, Slack, web pages)
- Format conversion to fit a target medium with strict character limits
Launch the tool
No upload, no signup, no daily limit.
Frequently asked questions
Will Diff Checker work offline?
Yes — once the page loads, processing happens locally with no further network calls.
Is there a length limit?
Practically, several MB of text. Beyond that the browser starts to lag.
Can Diff Checker handle non-English text?
Yes — it uses Unicode-standard rules that work for most major scripts.
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.
