// 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.

Iris scans. Personhood proofs. Government-linked credentials tied to every account.

Solves the bot problem at the cost of forcing every human onto a permanent identity rail. Once that rail exists, it doesn't come down.

PATH B · DETECT EVERY BOT

Deckrd.

Detection runs on the AI side of the conversation. The human is never asked to prove anything.

Solves the bot problem without inverting the relationship between the humanity and the right to privacy.

We don't ask humans to prove themselves. We make the bots prove themselves to the humans.
// 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.

Voice identity protection

Every video call app now has an uninvited AI note-taker. Some of them are training voice models on you. Deckrd protects your voice from recording or cloning.

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 text "from the bank" asking them to verify their account, or a call that sounds just like a real person, Deckrd catches what they might not.

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.

// how it works

Three steps. Zero configuration.

Install Deckrd and it works silently in the background, analysing conversations and rendering verdicts within degrees of confidence.

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 locally on your device. Nothing leaves your machine.

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 on your device. Nothing leaves your machine. 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. That's the category split.

// the roadmap

Detection across every modality.
Delivered on every surface.

Deckrd isn't a single product, it's a detection company that scales horizontally. As AI moves into voice, video and eventually presence, our detection moves with it.
