// 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. Strangers are never asked to verify — but you can verify your voice to people you trust.

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

We don't ask strangers to prove themselves. We detect bots — and let you verify your voice to people you trust.
// 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 or transcribed — and Verify lets family hear it's 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 live when it's 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

Passkeys for your voice.

Strangers are never asked to prove themselves. Verify is opt-in cryptography for your trusted circle — so family and close contacts can hear it's really you, live, not a recording or clone.

✓ Verified live — desktop alpha

While you talk, your Mac stamps your voice with a continuously refreshed signature only your device can produce. Contacts you've paired with see ✓ Verified live. A perfect AI clone still can't forge it — because the clone doesn't have your key. No voiceprint stored.

Not mandatory digital ID

Verify is a private, voluntary trust layer for people you choose — the opposite of forcing every human onto a permanent identity rail. Pair once out-of-band, then every call is checked automatically.

01

Pair a trusted contact — exchange identity keys and confirm a short SAS code out-of-band (like Signal safety numbers).

02

Start a call — Deckrd handshakes over a secure relay when you connect. Identity confirmed within seconds of first speech.

03

See the verdict✓ Verified live for the real person; ⚠ Unverified for a recording, relay, or clone.

// 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

Three capabilities.
Every modality. Every surface.

Deckrd isn't a single feature — it's Detect, Protect, and Verify, scaling across chat, voice, video, and every device where conversations happen.
