Revelio

About

Revelio is a security-focused browser extension that helps you inspect webpages for potentially hidden or deceptive text.

Attackers, prompt injectors, and low-quality pages sometimes hide content using CSS tricks (tiny font, low contrast, off-canvas positioning, transparent text, clipped elements, pseudo-content, and more). Revelio scans the current page and surfaces suspicious text so you can quickly review it.

What Revelio does:
- Detects text that may be intentionally hidden from normal view
- Highlights findings directly on the page
- Lets you click a finding to jump to where it lives in the DOM
- Shows confidence-oriented scan modes: Everything, Sweep, Default, Precise
- Exports findings as JSON for reporting or incident review

Built for security workflows:
- Web content review
- Prompt-injection and hidden-instruction checks
- QA and trust/safety investigations
- General page integrity auditing

Privacy-first by design:
Revelio runs locally in your browser on the active tab. It does not send page content to external servers.
