Introduction

Vouch verifies user-owned data with cryptographic proofs. The user signs in to their own account, proves the fact you asked for, and you receive it as JSON at your webhook.

AI-Resilient Verification

Vouch enables businesses to verify user-owned data with cryptographic proofs that defeat fraud, including AI deepfakes. No document uploads. No manual checks.

The user signs in to their own account, proves the specific fact you asked for, and you receive it as structured JSON. You never see their credentials or their whole account, and you need no platform API keys or partnerships.

Why businesses use Vouch

Checking a claim about a user usually means one of these, and they all fail in the same way:

The usual approachWhy it breaks
Ask for a document or screenshotTrivial to edit or generate, expensive to review, unstructured
Trust what the user tells youSelf-reported, and inflated more often than not
Use the platform's APIOften has no such endpoint, needs a partnership, or exposes only a subset
Buy third-party dataEstimates and inference, not what the account actually shows

Vouch replaces claim → upload → manual review → decision with claim → verify → decision. Reviews stop being a queue, and the friction that made users abandon the flow goes with it.

  • Universal data access: verify data from any source users can access online.
  • Zero integration: no platform API integrations or partnership agreements required.
  • Privacy-first: users control their data; you receive only verified proofs.

Send the user to Vouch

One SDK call returns a URL. The user signs in to the platform and confirms what will be shared. Quickstart →

A structured JSON payload, checked before it reaches you. Receiving results →

Most teams are live within days, and you run no verification infrastructure.

Two verification modes

Every verification runs in one of two modes.

Three verification channels

The mode decides how the proof is made. The channel decides where the user is standing when they make it. All three produce the same result payload.

The Vouch Verifier browser extension, the Vouch Verifier mobile apps, or our mobile SDKs inside your own app. Compare the three →
