About this tool
Lines up two texts line by line and marks which lines were added, removed, or left untouched. Useful for comparing two drafts of a document, or finding when a config file started to differ. Both inputs are compared inside your browser and are never transmitted.
When to use it
- —Pulling out only the changed sentences between two versions of a contract or proposal
- —Finding why the same config file fails on one server but not another
- —Checking that a translation has the same number of paragraphs as the source
Good to know
- —Comparison happens per line, so changing a few words marks the whole line as changed.
- —Trailing spaces and indentation differences also count as changes.
- —Very long documents may make the browser appear to pause while it computes.
