Chrome Extension · Logged-in capture · Proof ID · Evidence ZIP · Verify later

Capture the web as tamper-evident evidence — not just screenshots.

Turn what you see online into a proof you can verify later. Capture public URLs or logged-in pages (via extension), export an Evidence ZIP with hashes, and show a clear integrity result: Match or Modified.

Why this holds up better than screenshots: evidence is designed to be tamper-evident. If someone alters captured files later, verification is expected to expose the change.

Built for disputes, investigations, and compliance workflows (not legal advice).

Works in Chrome + Edge + Opera. (Firefox support can be added separately.)
Proof link

A Proof ID you can share for review and later verification.

Evidence ZIP

Portable package + manifest + SHA-256 hashes.

Verifier

Clear result: Match / Modified — with integrity details.

Evidence workflow
Capture → ZIP → Verify

Designed for fast capture when content may change, be edited, or disappear.

Option A — Capture a public URL
https://example.com/policy-or-post

Screenshot + extracted content + metadata (as available).

Option B — Capture what you see (logged-in)
Use the Chrome Extension to capture authenticated pages.

Useful when content is behind accounts, dashboards, portals, or paywalls you legitimately access.

Result — Proof ID + Evidence ZIP
Proof ID: 70352d57-d6bc-4873-87f2-d052b1bef548

Share the proof link or export an Evidence ZIP for third-party review.

Tip: Perfect for “what was shown” disputes (pricing, policies, promises, claims, profiles).
Tamper-evident integrity

Evidence packages include a manifest + SHA-256 hashes for later verification.

Public verifier

Verify by Proof ID or upload Evidence ZIP for integrity checks.

Logged-in capture

Capture what you see in your browser using the extension.

Note: “tamper-evident” means modifications are detectable; it does not guarantee legal outcomes.

Built for disputes, not just screenshots

Screenshots alone are easy to challenge. GetProofAnchor produces a structured, integrity-checked record you can reference and verify later.

Step 1 — Capture

Capture a public URL or what you see in your browser via extension.

Step 2 — Export

Export an Evidence ZIP with a manifest and SHA-256 hashes.

Step 3 — Verify

Verify by Proof ID (online) or verify the ZIP (offline) to detect modifications.

Important: GetProofAnchor does not judge truthfulness — it verifies integrity: whether a live page (or an evidence package) matches what was captured at a specific time.
