Crovia Seal · On your phone

One way. Install. Share. Sealed.

Apple and Google don't allow buttons inside chat apps. So the only sensible path is the system Share menu — that you already use to share photos, links and text. Same gesture, new option: Crovia Seal.

Open the Crovia Seal app

Android 2-tap setup

Once installed, Crovia Seal appears in the system Share menu of every app (ChatGPT, Claude, Gemini, WhatsApp, anywhere).

1

Tap the blue button above

Chrome opens the Crovia Seal web app, then offers to Install it. If not, open Chrome menu ⋮ → Install app.

2

That's it. Now use Share anywhere.

Long-press text in ChatGPT app → Share → Crovia Seal. The app opens with the text pre-filled, you tap Seal, the sealed text is on your clipboard. Paste anywhere as proof.

Pro tip: after sealing, the text now includes a visible croviatrust.com/v/sl_… link. Anyone who reads your message can click it to independently verify when the AI said it.

iPhone 3-tap workflow

iOS doesn't show our app in the share menu (Apple restriction). The workflow is one extra tap, but still simple and one-time-setup.

1

Add to Home Screen (one time)

Tap the blue button above in Safari, then Share → Add to Home Screen. The Crovia Seal icon appears next to your apps.

2

Copy AI text from any app

Inside ChatGPT app (or any other AI/messaging app): long-press the response → Copy.

3

Tap the Crovia Seal icon, then "Paste & Seal"

The app reads from your clipboard, seals the text, and copies the sealed version back. Paste wherever you want — the seal travels with the text.

Why not 1-tap on iPhone? Apple does not allow third-party apps in the share menu unless distributed through the App Store with platform-specific extensions. We chose to stay free and account-less, so you do one extra tap. Honest trade-off.
Is my text sent to Crovia servers?

No. The text is hashed locally on your phone (SHA-256). Only the hash + length are sent for signing. We never see your conversation. Privacy details.

Will the seal still be there if I paste into WhatsApp / email / Twitter?

Yes. The sealed text contains a visible croviatrust.com/v/sl_… link plus an invisible cryptographic mark. The visible link survives every platform. Anyone who clicks it sees the verification page.

I'm a power user — is there a desktop browser extension?

Yes. Get it here — a 🛡 Seal button appears inside ChatGPT, Claude, Gemini and Perplexity, right next to the native Copy/Like/Regenerate buttons.
