// the firewall for humanity

Two ways to fix this.
We're building the second.

Generative AI has crossed the line at which most people can no longer reliably tell. There are only two ways to solve the bot problem at scale. The platforms and governments are converging on one of them. We're building the other.

PATH A · VERIFY EVERY HUMAN

Mandatory digital ID.

A single digital ID that everyone must carry. Iris scans. Personhood proofs. Government or platform credentials tied to every account. Mandatory, universal, surveillance by default, irreversible once built.

PATH B · DETECT THE BOTS. VERIFY THE HUMANS YOU CHOOSE.

Deckrd.

Detection runs on the AI side of the conversation, so strangers are never asked to prove themselves. Verification is cryptographic and voluntary: you prove you are the live human to the people and organisations you choose, and nobody else. Bots must prove themselves to humans. Not the other way around.

We detect the bots. You verify yourself only to the people and organisations you choose. No registry, no mandatory ID.
// why deckrd

The human pulse is fading.

AI is getting better at sounding human, in your inbox, your DMs, your dating apps, even your family's phone. Deckrd is the layer of truth between you and the bots.

Protect your voice

Every video call app now has an uninvited AI note-taker. Some of them are training voice models on you. Deckrd Protect stops your voice being cloned, and Verify lets family hear it is really you.

Dating & social

The perfect match who always says the right thing. The new follower sliding into your DMs. When the chemistry feels too good to be scripted, Deckrd lets you know if it actually is.

Protecting family

When your parents get a scam call with a cloned voice of their child, or a text "from the bank" asking them to verify their account, Deckrd Detect catches the bots, and Verify shows trusted family ◉ VERIFIED when it is really you.

Recruiting & hiring

The candidate acing your interview in real time, is it them, or their AI? Make sure the person you're hiring is the one actually doing the talking.

// verify

Prove it's really you. Live.

PROTOTYPE · DEMO ON REQUEST

Verify is end-to-end authenticity for voice, the way the HTTPS padlock works for the web. Add someone you trust once. On every call after that, they see ◉ VERIFIED when it is really you, live, not a recording or a clone. The proof is cryptographic, not a judgement about how your voice sounds, so a perfect AI clone still fails. No voiceprint is ever stored. Technical specifics on request under NDA.

Not mandatory digital ID

Verify is voluntary. You prove you are the live human only to the people and organisations you choose. No registry. No mandatory ID.

01

Add a trusted contact. Add someone you trust once.

02

Start a call. On every call after that, they can see the verdict.

03

See the verdict. ◉ VERIFIED when it is really you, live. A recording or a clone does not pass.

// for people and for organisations

For people: peer to peer. You choose who you trust. Your proof lives on your device, no directory anywhere.

For organisations: the organisation is the trust anchor for its own people. It holds the directory, policy and audit trail in its own environment. Nothing about a staff member's voice leaves their device.

In both: the person holds the proof, the customer holds the directory, Deckrd holds neither.

// for organisations

Security teams can no longer tell human from machine.

AI is now inside every channel the organisation runs on. A deepfaked executive on a video call moved about US$25M at Arup in 2024. Deckrd is the authenticity layer: detect the AI reaching your people, protect their voices from cloning, verify the live human on high-stakes calls and approvals.

Deploys inside your environment, next to the identity stack you already run. You hold the directory, the policy and the audit trail. Deckrd never holds your proof, your voiceprint or your conversations.

// detect

Flag AI and deepfakes reaching staff through email, chat and voice. Text live, inbound voice in alpha.

Design
// how it works

Three steps. Zero configuration.

Install Deckrd and it works silently in the background, analysing conversations and showing results with confidence levels.

STEP 01

Install in seconds

Grab the browser extension from the Chrome Web Store or Firefox Add-ons. One click, no account, no setup. Launch the extension and Deckrd goes to work.

STEP 02

Deckrd watches silently

Our ensemble engine evaluates every conversation on your device. Message content never goes to Deckrd's servers.

STEP 03

Get real-time verdicts

A clear, instant signal when AI is detected on the other side of a conversation above a certain threshold of certainty. Human, AI, or still analysing. No guessing.

// what makes deckrd different

Passive. Always-on. Privacy-first.

Deckrd installs once and runs quietly in the background. When you open a conversation, it surfaces a verdict the moment one is reachable, without you ever asking, without your messages ever leaving your device.

Passive monitoring + active alerts

Other tools require you to copy and paste a suspicious message into a checker. By then it's too late. Deckrd watches in real time and tells you. You never have to suspect: we tell you when there's something to suspect.

Ensemble detection

Eleven independent local detectors running simultaneously. When generators get better at one signal, the others still hold.

Privacy-first by architecture

Patterns analysed where the conversation is: on your device for people, inside the organisation's own environment for enterprise. Never on Deckrd's servers. Deckrd sees structural shape, never message content.

DECKRD vs. COPY-AND-PASTE

Pasting messages into a third-party checker means the user has to already suspect a bot to find one, and means the message is uploaded somewhere. Deckrd watches the conversation as it happens, on-device, and tells you when it sees something.
