Diff Checker for students
For students, Diff Checker fills a gap most students 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 students 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

Frequently asked questions
Does Diff Checker count characters with or without spaces?
Diff Checker shows both counts simultaneously, so you can use whichever your target requires.
Does Diff Checker save my text?
No. Diff Checker processes everything in your browser; nothing is uploaded or stored.
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.
