TEXT OPERATIONS
Compare two inputs using a bounded longest-common-subsequence line diff and return unchanged, removed, and added lines in readable order.
WHAT THIS DOES
Runs entirely in your browser.
/tools/text-difftext-diffv4.0.0LOCAL · LOCAL RUNIMPLEMENTED — This workbench is functional in the current release.Presets for this workbench
No preset yet. A preset stores the values in this form — never the result — and only for workbenches that run entirely in your browser.

BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of before and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
A dynamic-programming longest-common-subsequence table reconstructs a line-level diff. Input is bounded to limit browser memory use.
Boundary: This is a line diff, not a character diff, merge tool, version control system, semantic comparison, or document upload service.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
This is a line diff, not a character diff, merge tool, version control system, semantic comparison, or document upload service.
No. This published tool runs locally in your browser. UtilityForge does not send the values entered in this workbench to a server.
No. This workbench runs in the page: Original text, Revised text are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: Original text (100,000 characters) and Revised text (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
