What “no uploads” should mean
“No uploads” isn’t a marketing phrase—it’s a behavior. The safest setup is when your text stays on your device and the comparison happens locally. In practical terms:
- The diff is computed in the browser (not on a remote API).
- Your content isn’t stored server-side, logged, or used for analytics/training.
- Sharing is explicit (you choose when and how to share a result).
A safe workflow for comparing two texts
1) Start with a clean paste
Paste the “before” version on the left and the “after” version on the right. If the text includes secrets (tokens, passwords), consider masking those sections first.
2) Use “ignore” options intentionally
Many differences are cosmetic. If you’re reviewing formatting noise, try ignore settings like whitespace or case to focus on meaning. If you’re reviewing code or exact copy, keep them off.
3) Check the summary first, then drill in
A good habit: start with the totals (lines added/removed), then skim the largest change blocks, then review the final output top-to-bottom.
4) Share safely (or don’t share at all)
If you must share, prefer sharing only the minimal necessary information. If your tool supports shareable links, treat that link like the document itself: anyone with the link can see the contents. Share it only with trusted recipients.
Common pitfalls (and how to avoid them)
- Invisible characters: copied text can include non-printing characters. If a diff looks “weird,” re-copy from a plain-text source.
- Formatting-only edits: use ignore whitespace for layout-only reviews, but don’t use it when exact formatting matters (poetry, code, tables).
- Over-sharing: screenshots and shared links can leak more than you intend. Redact before you share.
