Private AI browser · Windows early access
A privacy browser that enforces itself: trackers blocked, fingerprints spoofed, sessions wiped — and an AI agent that researches on your behalf, so websites never see you.
Canvas, audio, WebGL and navigator APIs return spoofed values, and WebRTC is killed entirely — closing the most common IP leak.
Known tracker and ad domains are blocked on every navigation and sub-resource request, not just the URL you type.
Cookies, localStorage, IndexedDB and cache are wiped when the session ends. Browsing history is never written to disk.
utm_*, fbclid, gclid, msclkid and other tracking parameters are stripped before any request is made.
Ask a question and an agent searches, fetches and sanitizes pages through a privacy gateway, then answers with every claim traced to a source.
Connect a local Ollama model to summarize, translate or explain the page you are reading — nothing leaves your machine.
Every action the agent proposes is checked against a fixed allowlist outside the model's context — a malicious page can't talk its way past it.
From Normal to Protected, Private, Anonymous (Tor) and AI Only — each an enforced configuration, switchable per session and always visible.
No account, no analytics SDK, no crash reporter, no silent updates. The only traffic Casper sends is traffic you initiate.
Type a question. Casper spots question-shaped input and routes it to the agent — no mode switch needed.
A local AI turns your question into targeted queries and fetches results through a privacy gateway.
Candidate pages are fetched headlessly and stripped of scripts, tracking pixels and hidden text before the model sees them.
You get a synthesized answer with sources. The sites you researched saw an anonymous request — not you.
Windows early access is live — no email, no account, no registration. macOS, Linux, iOS and Android builds are coming soon.
