AI can sound human, and AI-initiated communications are on the rise. Deckrd stands between you and the bots — so you always know who's on the other side.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Pair a trusted contact — exchange identity keys and confirm a short SAS code out-of-band (like Signal safety numbers).
Start a call — Deckrd handshakes over a secure relay when you connect. Identity confirmed within seconds of first speech.
See the verdict — ✓ Verified live for the real person; ⚠ Unverified for a recording, relay, or clone.
Install Deckrd and it works silently in the background, analysing conversations and rendering verdicts within degrees of confidence.
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.
Our ensemble engine evaluates every conversation locally on your device. Nothing leaves your machine.
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.
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.
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.
Eleven independent local detectors running simultaneously. When generators get better at one signal, the others still hold.
Patterns analysed on your device. Nothing leaves your machine. Deckrd sees structural shape, never message content.
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.
Deckrd isn't a single feature — it's Detect, Protect, and Verify, scaling across chat, voice, video, and every device where conversations happen.
Free during the open beta. Install in seconds. No account, no friction.
Detects AI across the chats you already use. ChatGPT, Discord, WhatsApp Web, Messenger, LinkedIn, X DMs, and more.
Detect AI on calls and in native chat apps. Protect your voice on Zoom, Meet, Teams, and every app using your mic. Verify a voice is genuine to family and trusted contacts — live in the macOS alpha.
The same Detect engine that powers the extension, exposed as @deckrd/sdk. Protect and Verify APIs ship later. Free tier: 10,000 detections/month.
