Deckrd: AI Detection από Deckrd.ai

Is the person on the other end of this chat a real human, or an AI?

Deckrd runs a panel of 11 detectors on every conversation you have and gives you a live AI-probability score. It watches Discord, WhatsApp Web, Messenger (facebook.com/messages), LinkedIn, and X/Twitter DMs out of the box, and can be opted into any other chat site with one click.

▸ WHAT IT CATCHES
• Timing patterns - response latency consistency, typing speed, message bursts
• Writing style - vocabulary diversity, sentence variance, punctuation fingerprints
• Conversation flow - topic drift, non-sequiturs, self-contradictions
• Style mirroring - AI often converges on your style or ignores it too obviously
• Persona consistency - biographical coherence across turns
• AI hallmarks - em-dashes, curly quotes, Oxford commas, "delve" and "navigate the complexities"
phrasing
• Response shape - long essay answers to short prompts, suspiciously enthusiastic topic latches

▸ HOW YOU SEE IT
A toolbar icon shows a live score while you chat. Click it to open the HUD-style popup with a
dual-gauge score ring, per-detector breakdown, and a list of every monitored tab so you can spot AI activity in the background while you're focused elsewhere. When any conversation crosses the AI-detected threshold, the icon flashes briefly to draw your eye.

▸ PASTE-TO-ANALYZE
Beyond live chat, the Analyze tab lets you paste long-form prose (essays, emails, blog posts, LinkedIn updates) and get an AI-probability score on demand. Best on text 200 words or longer; chat-style short replies are a known blind spot and live monitoring remains the stronger tool for those.

▸ PRIVACY BY DESIGN
Every detector runs client-side in the extension. No chat content, no message text, no conversation history is ever transmitted. The only data leaving your device is your sign-in credentials (to our authentication service) and, if you choose to submit a bug report via the in-extension Feedback button, the technical diagnostics you include with it.

UPDATE - Account is no longer required to use Deckrd, but there are benefits for being part of the founding tester team

▸ ACCOUNT REQUIRED
Deckrd requires a Deckrd account to run. A free tier supports 2 devices per account; a Pro tier (currently awarded to Founding Testers, Alpha Testers, Closed Beta Testers, and VIP invitees as lifetime Pro) supports 10. Sign up or request an invite at deckrd.ai.

▸ COMPANION DESKTOP APP (Coming soon)
An optional macOS desktop app (Tauri-based) monitors any chat window, voice call, or video call system-wide. The extension can pipe captured messages to the desktop app via an optional localhost WebSocket bridge when both are running.

▸ BUILT FOR AUDIT
Deckrd runs a bounded set of detectors with documented weight configurations - no opaque ML model making calls in a black box. Detection logic ships out-of-band so we can tighten it as AI evolves without pushing new extension builds every week.
