COMPARISON RESULT
DESIGNED TO BE EXPLICIT
Your rules.
Your source of truth.
Local, not invisible
Comparison runs in your browser. Document contents are not sent to a server, added to links, or saved automatically. The site host still receives normal page requests. Clear removes inputs and rendered results from this tab, but is not a guarantee of forensic memory erasure.
Exact where it matters
Imported file line endings are preserved until you edit that side. The editor displays LF; editing adopts that newline format. Pasted text may already be newline-normalized by your browser. In JSON mode, numbers keep their original tokens, including large integers and exponents. Paths use JSON Pointer notation. Root changes are labelled "(root)". Limits or errors never count as an identical result.
Know the limits
Text files only, not Word or PDF. Word emphasis is best effort on short adjacent replacement lines. JSON allows up to 64 nesting levels, 30,000 values per side and 5,000 changes. Large comparisons can stop at the time or cost limit. Reports contain your compared content, so share them carefully.
