Everything They Block.
Nothing They Take.

Nine layers of protection built into the browser — not an extension you install, a permission you grant, or a policy you hope they keep.

Threat Narrator

See who tracks you in plain English. Every tracker named, counted, and explained — not just a number in a shield.

Encrypted Vault

Save anything. GPS stripped. Camera data removed. Encrypted before it touches your disk. Crypto-shred any category in an instant.

On-Device AI

Summarise pages, detect phishing, check privacy — all in an isolated process with zero network access. Not a policy. Physics.

Writing Style Detection

Your bank writes a certain way. Phishing pages get the visual design right but the writing wrong. We catch what URL checkers miss.

Arabic Intelligence

Six dialects. RTL override attack detection. Homoglyph identification. Mixed-script domain warnings. The only browser built for Arabic speakers.

Behavioral Lock

Your browsing rhythm becomes your encryption key. Even with stolen credentials, an attacker cannot match your keystroke timing.

Zero-Knowledge Vault

Save passwords, import from Chrome/Firefox/Safari, sync with 1Password and Bitwarden. When AI fills a login form, it never sees the password — a single-use token handles the injection. Crypto-shred any category instantly.

Per-Tab VPN Tunneling

Route any tab through Saj Loop VPN with one click. Each tab gets its own SOCKS5 tunnel — your banking tab uses a VPN while your news tab doesn't. Same exit IP across all navigation. DNS leak proof.

49 MCP Tools

AI agents can navigate, click, fill forms, audit security, extract data, and capture design sessions — all through the MCP protocol. Each agent gets its own browser tab. Zero cross-session interference.

Every other browser sends your data to a cloud.
We don't even have a cloud.

Saj Browse's AI runs in an isolated process on your device with no network access. This isn't a privacy setting you can toggle — it's how the software is built. The AI component physically cannot reach the internet.

When you ask the AI to analyse a page, it reads the DOM in memory, processes it locally, and returns a result. Nothing leaves your machine. There is no request, no response, no log.

Built for AI Agents

Saj Browse ships an MCP (Model Context Protocol) server that lets AI assistants like Claude, Cursor, and Windsurf control the browser programmatically. 49 tools for navigation, form interaction, security auditing, accessibility testing, and design capture — all with per-session tab isolation so multiple agents work simultaneously without interference.

Part of Something Bigger.

Saj Browse is one piece of a sovereign technology ecosystem. Every product shares the same principle: your data belongs to you.

Privacy Shouldn't Cost a Fortune.

The most important protections are free — because security that only wealthy people can afford isn't security at all.
