Que fait Text Diff ?
Text Diff permet de comparer des entrées dans le navigateur et présente clairement le résultat et ses limites. Fonctions vérifiées : Line-by-line diff, Whitespace normalization, Copyable patch view, Local comparison.
Line diff favors readable revisions
Use this page for configuration files, lists, and prose already divided into meaningful lines. Use JSON Diff for parsed JSON semantics or a word-level review tool for dense paragraphs.
Comment l’utiliser ?
- Paste the earlier text into Original text and the revision into Changed text.
- Enable Ignore whitespace only when leading, trailing, and repeated spaces should not create a change.
- Read the + and − lines, then copy the plain patch view if needed.
Exemple réel d’entrée et de sortie
Replace one complete line

Original:

- betaThis implementation finds a longest common sequence of complete lines; it does not highlight changed characters inside a line.
Erreurs fréquentes et corrections
| Symptôme | Cause probable | Correction |
|---|---|---|
| One edited sentence appears as a removal plus an addition. | The current comparison unit is the complete line. | Break long prose into stable lines or use a word-level diff when character-level review is required. |
| The page stops a very large comparison. | More than four million line pairs would require unsafe browser memory for the comparison table. | Compare smaller sections or use a streaming command-line diff for large files. |

Text Diff — FAQ
Does the Text Diff upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the Text Diff accept?
It accepts an original text and a changed text. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the Text Diff produce?
It produces a readable line diff with plus and minus markers. Copy and download controls appear when the output format supports them.
What limitation should I know?
This release compares complete lines; a changed line appears as one removal and one addition.
Quelles modifications ?
Mise à jour substantielle : Text Diff: Added Line-by-line diff, Whitespace normalization, Copyable patch view, Local comparison, responsive controls, explicit runtime disclosure, and task-specific examples and limitations.
