How to Create a Proof from a Public URL

Before you capture (quick checklist)

The goal is simple: capture the exact page you care about, at the moment it matters. A strong proof starts with the right URL and timing.

✅ Good candidates for capture

news articles and blog posts
public social posts / public profiles (via URL)
pricing pages, policies, Terms, Privacy, legal pages
product pages, listings, “what was promised” pages

Method A — Create a proof from the dashboard (all plans)

This is the standard workflow: you sign in, paste a URL, and create a proof. It’s the fastest way to produce a Proof ID and export Evidence ZIP.

Step 1 — Open the dashboard

Go to /app and sign in. In the dashboard, you’ll see the option to create a new proof.

Step 2 — Paste the public URL

Paste the exact URL you want to capture. Example: https://example.com/article

Step 3 — Create proof

Start the capture. GPA records what was visible on that URL at that moment. Your proof will be created as a tamper-evident record.

Step 4 — Copy the Proof ID (and optionally export Evidence ZIP)

After creation, you get a Proof ID in dashboard. You can share the proof link, and if needed export an Evidence ZIP for case files, external review, or offline verification.

Tip for evidence workflows

If this is for a dispute, investigation, or formal review, export the Evidence ZIP and archive it. Later you can demonstrate the ZIP is original and unchanged using verification.

The Browser Widget lets you create proofs directly from your browser while you’re viewing a page. This is especially useful when you need to capture exactly what you see on-screen quickly.

Who can use the widget?

Widget capture is available for Enterprise and Business plans. If you don’t see widget options, check your plan in the dashboard.

Step 1 — Install and sign in (once)

Install the Browser Widget, then authenticate it with your GPA account. After that, you can capture pages without switching tabs.

Step 2 — Open the target page

Navigate to the page you want to capture. Make sure the key content is fully visible (scroll if needed).

Step 3 — Click “Capture with GPA”

Trigger capture from the widget. GPA creates a proof record and returns a Proof ID. From there, the workflow is the same: you can open the proof page, export Evidence ZIP, and verify later.

When the widget is the better choice

you need to capture quickly while reviewing content
you want “what I saw in the browser right now” captured fast
you’re doing repeated captures (change tracking, investigations)

Common mistakes (avoid weak proofs)

Capturing the homepage instead of the specific page that contains the claim.
Capturing too late after the content was already edited or removed.
Not waiting for the page to load (missing key text/images).
Assuming private content can be captured (GPA focuses on public URLs).

Next steps

Once you’ve created your first proof, the next skill is verification: how to prove the evidence wasn’t altered later.
