Questions

Line or word mode?

Line mode is best for code, lists and data. Word mode is better for prose, where a single edit would otherwise mark a whole paragraph as changed.

Is there a size limit?

The comparison runs in your browser and handles documents of several thousand lines comfortably. Nothing is uploaded.
