powered by PDQ perceptual hashing

Your intimate images,
protected forever

Corvinth detects and removes non-consensual intimate images across platforms — even when rotated, cropped, or re-uploaded.

Three steps to protection

No images ever leave your device. We only process a digital fingerprint — a hash — that cannot be reversed into your photo.

1

Select your image

Choose the image you want to protect. It stays on your device — only a fingerprint is ever sent.

2

We generate a hash

Our PDQ algorithm creates a unique fingerprint that matches the image even if rotated, flipped, or re-saved.

3

Platforms are alerted

Partner platforms scan every upload against your hash. Matches are flagged and removed automatically.

Built for real-world abuse patterns

Rotation tolerant

Detects your image after 90°, 180°, or 270° rotation — a common evasion tactic.

Zero image storage

Your actual photo never touches our servers. Only a mathematical fingerprint is stored.

Always-on scanning

Once registered, your hash is checked against every upload to partner platforms in real time.

Platform API

Built for scale. Platforms integrate our REST API to scan content before it goes live.

One API. Instant protection.

Integrate Corvinth into your content pipeline with a single POST request. Protect your users before harm occurs.

Built for developers, designed for trust

Our REST API is simple to integrate and built on the same PDQ hashing standard used by Meta, TikTok, and Reddit.
