A few frames is all it takes
At 60 fps, a "barely visible" flash is dozens of perfectly sharp frames. Each one is a screenshot of your secrets.

Leak nothing.
Voksa is a desktop browser built for streaming. Emails, IP addresses, phone numbers and your own secret keywords are masked on screen before a single frame can escape. Not blurred after the fact. Never painted at all.

The problem
One leaked frame is
leaked forever.
You share your screen, open one wrong tab, and your email, your client's name or your home IP is on the recording. Your VOD keeps every single frame. Anyone can download it, scrub frame by frame, and stop exactly on the one that should never have existed.
Masking add-ons react too late
Browser extensions run inside a page that is already drawn. They hide content after it was painted, and after your stream captured it.
The VOD never forgets
Twitch, YouTube, a Zoom recording: the replay is public, downloadable and pausable. The leak outlives the moment, forever.
The solution
Stream Mode.
A zero-leaked-frame guarantee.
Voksa is not an add-on fighting the browser. Voksa is the browser. So it can do the one thing nothing else can: keep sensitive pixels from ever being drawn.
Pages load invisible
From the very first byte, every page is held invisible. There is nothing to capture, on any load, reload, new tab or iframe.
Secrets are rewritten first
IPs, emails, phone numbers and your keywords are masked directly in the page, synchronously, before the next paint. Even content that appears mid-stream.
Revealed only when clean
The page appears already masked, in the same frame. By construction there is no transition window, so there is nothing to scrub for.
Protection by construction. Not by reaction.
Everything included
Built for the worst case.
Pleasant every day.
Masks everything sensitive, live
Public IPv4 and IPv6 addresses, emails and phone numbers are redacted on every page, as pages load and change. Form fields are visually redacted while you type; what you submit stays intact.
Your own keywords
A client's name, a project codename, your username: add them once, they vanish everywhere.
The browser masks itself too
Tab titles, address bar, suggestions, history surfaces: masked. Structurally impossible for an extension.
Turns itself on
Launch OBS, Streamlabs, XSplit or vMix and Voksa arms Stream Mode by itself, before you even hit "Start streaming".
Hardware stays private
Camera, microphone, location and screen-capture requests are auto-denied on stream. WebRTC, the classic IP leak, is blocked.
A real, full browser
Sign in to Google, Gmail and YouTube normally. Install uBlock Origin, Bitwarden and friends straight from the Chrome Web Store. Bookmarks with nested folders, downloads, find in page, print preview, session restore, full dark mode, French and English, silent auto-updates.
The honest comparison
Why not just a masking extension?
