Your Fingerprint

A quick audit of how you overshare. Paste your last few AI prompts, sent messages, or emails. ShareLess looks at your own outgoing activity — locally, in this tab — and shows where ordinary oversharing and invisible side-channels leak more than you meant, paired with a lower-leakage way to share the same thing.

• Runs entirely on your device — your text is never uploaded.
• Two tracks, weighted equally: visible oversharing and invisible side-channels.
• Every leak comes with a concrete fix, not just a warning.
