Text Diff Checker
Compare two versions of a draft side by side. Spot insertions and deletions by character, word, or line without sending text away.
Drop the previous copy in one box and the revised copy in the other. The checker highlights what changed, it does not merge files like git.
Diffing runs with a client-side library in this tab so drafts never leave the machine.
How to use
- Paste text A and text B.
- Pick character, word, or line granularity.
- Scan highlighted insertions and deletions.
How it works
Word mode is the default for prose. Character mode catches tiny edits like a missing comma. Line mode suits config files and poetry with stable rows.
The output is a visual diff only. It does not write a patch file.
Examples
Legal clause
Two contract paragraphs that differ by a single adjective show a tight word-level highlight.
Config file
Line mode flags a renamed key in a .env paste without drowning you in character noise.
FAQ
Can I diff binary files?
No. Paste plain text only. Images and documents need another workflow.
Which mode should I start with?
Word mode for articles. Line mode for code-like rows. Character mode for tiny typos.
Is this a git diff?
No. It compares two pastes in the page. It does not read a repository.
Are drafts stored?
No. Comparison stays in this browser tab.
