Lives in the corner of the screen. Loud only when it matters.
An always-on extension that knows the difference between a meme and a manipulation. It does not slow you down, take over your tab, or push notifications. It puts a small honest label on what you're already looking at — then gets out of the way.
AI Detector
Inline ribbons on text, images, audio and video. Confidence score, model fingerprint, and one-click 'show me why.'
Manipulation Lens
Highlights confirmshaming, urgency timers, sponsored disguised as organic, and emotional-priming headlines.
Prompt Firewall
Before you send a message to any AI assistant, Defog scans it for 180+ sensitive data categories: personal identifiers, company confidential markers, regulated health information, financial account data. If a match is found, you see exactly what triggered the flag and choose what to do. Your AI usage. Your information. Your call.
Reality Score
Your weekly exposure: % of feed AI-touched, # of dark patterns, # of would-be PII leaks blocked. The first number about your digital life that actually matters.
Provenance Chain
Right-click any image: see every other site it appears on, with what caption. Crowd-sourced. Cryptographically verifiable when sources sign.
EXIF X-ray
Drag any image into Defog: shutter speed, lens, GPS (if present), edit history, AI generator if known. The metadata most platforms strip — restored.
Caspian — your AI, with your memory, under your control.
A local-first companion that reads what you read, remembers what you ask it to, and never trains on you. The opposite of the assistants the platforms are pushing.
